[PATCH v5 0/8] clk: sunxi-ng: Add support for Allwinner A733 CCU and PRCM

[Junhui Liu]

Add support for the main CCU and the PRCM module (R-CCU) found in the
Allwinner A733 SoC. The clock architecture is derived from the previous
A523 design, with the MCU_CCU removed and the clock tree extended for
the additional functional blocks found on the A733.

The A733 introduces a "pll-ref" clock that normalizes the physical
oscillator frequency, which can be 19.2MHz, 24MHz, or 26MHz, into a
consistent 24MHz reference for the PLL clock tree.

The peripheral, video, and DE PLLs provide multiple independently gated
outputs with programmable dividers. Model these outputs as separate
divider-and-gate child clocks. Also follow the documented hierarchy for
the derived peripheral PLL outputs. The explicitly named PLL_AUDIO1 /2
and /5 outputs are modeled as fixed-factor clocks, with their divider
fields initialized accordingly.

Also extend the sunxi-ng SDM (Sigma-Delta Modulation) support for the
dual-pattern register layout used by the A733 PLLs. PLL_AUDIO0 uses the
dual-pattern SDM support to synthesize its fractional output.
PLL_AUDIO1 does not expose fractional rates, but its SDM controls are
modeled so that stale settings left by firmware can be disabled when an
integer rate is programmed.

The actual parents of a small number of bus gates are not documented in
the user manual. Follow the vendor BSP and keep these gates parented to
"hosc" until more complete hardware information is available.

This series depends on the A523 single-divider clock fixes [1], which
add feature support to the M-only clock macro used by the MBUS and DRAM0
clocks. The prerequisite series has been applied to the
sunxi/clk-for-7.4 branch.

[PATCH v5 1/8] dt-bindings: clk: sun60i-a733-ccu: Add Allwinner A733 support

[Junhui Liu]

The CCU and R-CCU (PRCM) modules provide clocks and reset functions for
the Allwinner A733 SoC. The clock architecture of the A733 is evolved
from the A523, though the root clocking strategy transitions from a
static oscillator frequency in the Devicetree to the "hosc" clock, which
is determined by choosing from three possible frequencies (19.2MHz,
24MHz, or 26MHz) by the RTC hardware, and finally feeds the CCU and
R-CCU.

Additionally, the MCU_CCU module found in previous designs is removed
from the A733, and the clock tree is expanded with more clock outputs
to support new functional modules.

[PATCH v5 2/8] clk: sunxi-ng: sdm: Add dual patterns support

[Junhui Liu]

On newer Allwinner platforms like the A733, the Sigma-Delta Modulation
(SDM) control logic is more complex. The SDM enable bit, which was
previously located in the PLL register, is now moved to a second
pattern register (PATTERN1).

To support this, rename the existing "tuning" members to "pattern0" to
align with the datasheet, and introduce the _SUNXI_CCU_SDM_DUAL_PAT
macro to provide pattern1 register support. Related operations are also
updated.

[PATCH v5 3/8] clk: sunxi-ng: a733: Add PRCM CCU

[Junhui Liu]

Add support for the Power Reset Clock Management (PRCM) module found in
the Allwinner A733 SoC. This clock controller manages the clock control
and reset functions for device modules within the CPUS domain.

The PRCM module includes the management of three primary buses: r-ahb,
r-apb0, and r-apb1. It also provides clocking for several key
peripherals, such as R-UART, R-I2C, R-SPI, and the R-RISCV subsystem.
Additionally, the reset lines for these modules are integrated.

[PATCH v5 4/8] clk: sunxi-ng: a733: Add PLL clocks support

[Junhui Liu]

Add PLL clock support for the main CCU of the Allwinner A733 SoC. The
structure is mostly similar to the sun55i, with the addition of a
PLL_REF clock that normalizes the hardware-detected DCXO/hosc frequency
(19.2MHz, 24MHz, or 26MHz) into a consistent 24MHz reference for all
subsequent PLLs.

Model the independently gated outputs of the peripheral, video, and DE
PLLs as programmable-divider child clocks, with each output gate modeled
separately. Follow the documented hierarchy for the derived peripheral
PLL outputs.

PLL_AUDIO0 uses SDM parameters from the vendor driver to provide a
22.5792MHz * 4 output. PLL_AUDIO1 provides fixed /2 and /5 outputs and
does not expose fractional rates, but its SDM controls are modeled so
that stale firmware settings can be disabled when an integer rate is
programmed.

[PATCH v5 5/8] clk: sunxi-ng: a733: Add bus clocks support

[Junhui Liu]

Add the essential bus clocks in the Allwinner A733 CCU, including AHB,
APB0, APB1, APB_UART, and MBUS. These buses are necessary for many other
functional modules. Additional clocks such as trace and gic are also
added as they fall within the register address range of the bus clocks,
even though they are not strictly bus clocks.

The MBUS clock is marked as critical to ensure the memory bus remains
operational at all times. And the hardware requires an update bit
(bit 27) to be set so that the configuration takes effect and the
updated parameters can be correctly read back for the MBUS clock.

The GIC clock is also marked as critical. The bootloader may leave the
GIC running on a PLL parent, and disabling that PLL during
clk_disable_unused would hang the interrupt controller and the system.

[PATCH v5 6/8] clk: sunxi-ng: a733: Add mod clocks support

[Junhui Liu]

Add the module clocks found in the Allwinner A733 SoC, including video,
storage, interfaces and others. While most of these clocks are similar
to those in the A523 SoC, this implementation accounts for changes in
register offsets and introduces support for new modules.

[PATCH v5 7/8] clk: sunxi-ng: a733: Add bus clock gates

[Junhui Liu]

Add the bus clock gates that control access to the devices' register
interface on the Allwinner A733 SoC. These clocks are typically
single-bit controls in the BGR registers, covering UARTs, SPI, I2C, and
various multimedia engines. It also includes bus gates for system
components like the IOMMU and MSI-lite interfaces.

Also mark the ahb-store, mbus-store and ahb-cpus clocks as critical.
Disabling either store gate breaks access to boot/storage devices such
as MMC and SPI NOR, while gating ahb-cpus hangs any access to the CPUS
power domain registers when unused clocks are disabled.

[PATCH v5 8/8] clk: sunxi-ng: a733: Add reset lines

[Junhui Liu]

Add the reset lines for the Allwinner A733 SoC. These reset control bits
are integrated into the Bus Gate Reset (BGR) registers, typically
sharing the same register address with their corresponding bus clock
gates. Integrate them into the main CCU driver using the existing
sunxi-ng ccu_reset framework, allowing the CCU to also function as a
reset controller for the SoC.

Re: [PATCH v5 0/8] clk: sunxi-ng: Add support for Allwinner A733 CCU and PRCM

Hi folks,

Gentle ping on this series.

It would be great if this could make it into v7.4, as other A733 drivers
can then be developed on top of the clock/reset support provided by this
series.

Some of the clock controls, like the PLL and AHB/APB bus dividers, are
secure by default and need to be set to non-secure for Linux to be able
to use them properly. And there is also a TWD clock in the PRCM that the
user manual says is secure only.

Have you given any thought to this? If we end up having to convert to
SCMI or something to handle those clocks it's going to be a bit ugly.

And presumably things work now because the secure/non-secure access bit
isn't in effect right now because you aren't using secure boot? At least
this was a thing in the past...


Thanks

Re: [PATCH v5 0/8] clk: sunxi-ng: Add support for Allwinner A733 CCU and PRCM

[Norman Herms]

Hi ChenYu,

> And presumably things work now because the secure/non-secure access bit
> isn't in effect right now because you aren't using secure boot?

Yes, on our side. One data point from a single board type, Radxa Cubie
A7S, two boards. The measurements and this summary were done by AI
agents (Claude) working on my boards, so please read it as a report,
not as a Tested-by.

- Secure boot is not enabled on these boards: SID + 0xA0 (0x030060A0,
  SID_SECURE_MODE in the vendor boot0 sources; the UM does not describe
  the SID) reads 0 on both. The notes under PRCM_SEC_SWITCH_REG (UM
  V1.00 4.2.5.26) say these registers are always non-secure when the
  system is in non-security mode.

- The vendor BL31 blob in Radxa's u-boot package (v2.5) opens the
  switches at boot: PRCM_SEC_SWITCH_REG |= 0x7, then 0x7 to
  CCMU_SEC_SWITCH_REG at 0x02003F00. TF-A's sunxi_security_setup()
  does the same for the H6/H616.

- On the A733, CCMU_SEC_SWITCH_REG is at CCU + 0x1F00 (UM 4.1.6.278),
  not 0x0F00 as on the H6/H616; here 0x0F00 is SPI0_CLK_REG (UM
  4.1.6.160). The A733 TF-A port at github.com/dlan17/trusted-firmware-a
  (branch A733, f4c0b0dba, the commit Radxa's package pins) still uses
  0x0F00. On one of our boards the 0x7 ended up in SPI0_CLK_REG until
  we moved it to 0x1F00.

- TWD: UM 4.2.5.9 marks S_TWD_BGR_REG as fixed secure. We have not
  measured it.

Boot chain on these boards: vendor boot0 (DRAM init), U-Boot SPL and
U-Boot from Radxa's A733 tree with a few board patches, TF-A
lts-v2.12.15 with the A733 port above plus our fixes.

Thanks,
Norman

The three bus dividers are secure by default, and either need to be toggled
to non-secure by the bootloader, or (I'm guessing) the system is running
without secure boot and the secure access bit isn't in effect.

Please add a comment about this.

User manual says this is secure only. I suggest at least adding a comment
if not removing it altogether. Or perhaps someone could clarify with
Allwinner what this does.

BSP sources say there is a "dma-clken-sw" gate at 0x1dc bit 0. Same on the
A523, though it's unclear what it does or controls.

Thanks for pointing this out. This is indeed something I had not
considered before. I will try enabling secure boot on my spare Cubie A7Z
board and test it on actual hardware.

For the PLL and AHB/APB bus clock controls, the user manual indicates
that the relevant security bits can be set by TF-A to allow the kernel
to access these registers. This also appears to be how this has
traditionally been handled on sunxi platforms. So I think we can do the
same in TF-A for the A733.

For bus_r_twd_clk, I will test whether the register is indeed always
secure. If it is, I think the clock can be removed from the kernel and
left enabled by its hardware reset value or by the boot firmware.

I will try to test this on a board with secure boot enabled. If the
register is indeed inaccessible from the non-secure world, I will remove
this clock.

I checked the vendor BSP available to me and found that dma-clken-sw is
present in the sun60iw1 R-CCU driver, but not in the sun60iw2 R-CCU
driver.

The A733 corresponds to sun60iw2. Since this clock is neither documented
in the A733 user manual nor present in the vendor A733 (sun60iw2) clock
driver, I don't plan to expose it in the A733 driver.

Re: [PATCH v5 3/8] clk: sunxi-ng: a733: Add PRCM CCU

[Norman Herms]

Hi ChenYu,

Measurements for your comments on this patch. Same two Radxa Cubie A7S
boards and boot chain as in my reply to the cover letter (SID + 0xA0 =
0, no secure boot). Cold boot, register reads from U-Boot at
non-secure EL2 on both boards (same values). On one board also a
non-secure write test, and reads from EL3 with a test BL31 that only
reads, before and after sunxi_security_setup(). Again done by AI agents
(Claude) on my boards, so a report, not a Tested-by.

On our boards the bootloader toggles them. Bit 0 of PRCM_SEC_SWITCH_REG
(UM 4.2.5.26) covers exactly AHBS/APBS0/APBS1, and TF-A's common
sunxi_security_setup() writes 0x1 to that register (our BL31 and the
vendor BL31 set 0x7). From EL3 it reads 0 before and 0x7 after that
write. From non-secure: 0x07010290 = 0x7, r-ahb = 0x03000000, r-apb1 =
0x04000000. Both differ from the reset value 0, so these registers are
readable. We have not checked non-secure access to them before BL31
sets the switch. Note that secure filtering is active on these parts
even without the fuse, see the TWD gate below.

On our boards it behaves like that even without secure boot. From EL3,
S_TWD_BGR_REG (0x0701012C) reads its UM default 0x1, before and after
the BL31 security setup, so the gate is open after reset. From
non-secure it reads 0 on both boards, and a non-secure write of 0x1
does not stick.

The A733 UM lists no register at 0x1DC (the S_PRCM list goes from
0x01CC to 0x020C). In the Radxa BSP (radxa/allwinner-bsp, branch
cubie-aiot-v1.5.0) "dma-clken-sw" exists in ccu-sun55iw3-r.c and
ccu-sun60iw1-r.c, but not in ccu-sun60iw2-r.c, the A733 one. On our
boards 0x070101DC reads 0 from non-secure.

Norman

First a correction to my earlier reply in this thread. I answered
ChenYu's "presumably ... the secure/non-secure access bit isn't in
effect" with "yes" and quoted the UM note that these registers are
always non-secure in non-security mode. On our non-fused A7S boards
(SID + 0xA0 = 0, also when read from EL3) that does not hold for every
register. Read from EL3 with a test BL31, CCMU_SEC_SWITCH_REG is 0x7
after BL31's security setup, S_TWD_BGR_REG is 0x1 and the SPC status
registers are 0xffffffff, but from non-secure all of them read 0, and
non-secure writes to the first two do not stick. So secure filtering
is active on these parts even without the fuse.

That is what the BL31 on our boards does: PRCM_SEC_SWITCH_REG |= 0x7
and 0x7 to CCMU_SEC_SWITCH_REG at CCU + 0x1F00, as the vendor BL31
does. From EL3 both read 0 before and 0x7 after. The 0x1F00 versus
0x0F00 trap in the A733 TF-A port is in my first reply.

On our non-fused boards it is already inaccessible from the non-secure
side (reads 0, writes ignored). From EL3 it reads 0x1, the UM default,
so the gate is open. Details are in my reply to ChenYu on patch 3/8,
which crossed with yours.

Same boards and caveats as before: AI agents (Claude) on my boards, a
report, not a Tested-by.

Thanks,
Norman

Hi Norman,

Thanks for testing this. You saved my A7Z board from an almost certain
sacrifice. :)

I will double-check this on my side and add the relevant comments as
Chen-Yu suggested.

Understood. This bus gate is therefore not meaningful to the kernel,
so I will remove the clock in the next version.

A data point for that comment, measured since my last reply. For the
registers behind a security switch, ChenYu's guess holds on our boards.
Two test BL31s, each clearing a switch again after
sunxi_security_setup(), then reads and writes from U-Boot at
non-secure EL2:

- PRCM_SEC_SWITCH_REG bit 0 cleared (0x07010290 reads 0x6): r-ahb
  reads 0x03000000 and r-apb1 0x04000000, the values EL3 reads, and a
  write to r-apb0 (0 -> 1 -> 0) sticks.

- CCMU_SEC_SWITCH_REG cleared to 0 (PLL, BUS and MBUS secure): PLL_PERI0,
  AHB, APB0, APB1, TRACE, the AHB and MBUS master gating, NSI and MBUS
  read the values EL3 reads. Writes to PLL_NPU pattern 0 and to TRACE
  stick, and U-Boot's own write to the MBUS gate enable register
  (0x4 -> 0x804) sticks.

So on these non-fused parts (SID + 0xA0 = 0) the switch bits do not
gate non-secure access, as the UM notes on these registers say for
non-security mode. With secure boot enabled, the bootloader has to set
them; we cannot test that.

That narrows what I wrote earlier about secure filtering without the
fuse: on our boards it applies to the registers the UM marks as fixed
secure (S_TWD_BGR_REG), to CCMU_SEC_SWITCH_REG itself and to the SPC
status words, not to the registers behind a switch. We tested a sample
of each switch group, not every register.

One board, AI agents (Claude) on my board as before, so a report, not
a Tested-by.

Thanks,
Norman
