This series adds SoC-level CAMSS support for the Qualcomm SM8150
(Snapdragon 855), based on v7.4-rc1.
SM8150 contains four CSIPHY, four CSID (two full and two lite), two
VFE and two VFE-Lite instances. The blocks are close to the existing
SDM845/SM8250/SC8280XP implementations, so the driver change only adds
platform data and hooks the SoC into the existing Gen2 CSID and
VFE 17x code paths.
As requested in the v2 review, the CSIPHY I/O spaces, clocks,
interrupts and supplies are excluded from the CAMSS container device
and instead described by four qcom,sm8150-csi2-phy nodes driven by the
dedicated CSI2 PHY driver. Each PHY node feeds one CAMSS CSI input
port and is fed by the core and timer clocks, the vdda-phy and
vdda-pll supplies, and the Titan top power domain. No new register
programming sequences are introduced: the PHY driver reuses the
existing SC8280XP lane register table.
The series documents the SM8150 CCI compatible, which the CCI nodes use
with qcom,msm8996-cci as the fallback. The patches are ordered bindings
first, then driver data, then the DT description. The series is
intentionally SoC-level only: it does not add a board DTS, camera
sensor drivers, or board-specific camera wiring.
Testing: with a local Pixel 4 (google-flame) board port and
out-of-tree sensor drivers, the rear wide (IMX363), rear tele
(IMX481), front (IMX520) and IR (dual OV7251, patched driver)
cameras stream. The board port itself is not part of this series.
checkpatch reports no errors. The only warning is the new-binding
"MAINTAINERS needs updating" prompt, which is a false positive because
the existing CAMSS entry already covers qcom,*camss* bindings.
dt_binding_check passes for qcom,sm8150-camss.yaml and
qcom,sm8150-csi2-phy.yaml, and the new PHY/CAMSS drivers and DTS build.
Changes in v3:
- Switch to the new CSI2 PHY driver (Vladimir's v2 review request):
new qcom,sm8150-csi2-phy binding + driver, four phy@ nodes linked to
CAMSS CSI ports. CAMSS keeps only VFE/CSID resources (19 clocks,
8 IRQs). Timer pinned to 300 MHz (SM8150 timer only supports
19.2/300 MHz).
- Fix VFE lite clock match: restrict prefix match to numbered
"vfe_liteN" clocks to avoid matching aux clocks.
- Binding/DTS cleanup: patternProperties for ports, reg/reg-names after
compatible, sorted required list, redundant minItems dropped, aligned
example (lowercase hex, wrapped interconnects, isp@ name), ports
required, remote-endpoint in example, cam_hf_1_mnoc last, SDA/SCL
pinctrl comments, remote-only SoC endpoints (Glymur pattern).
- Order SM8150 before X1E80100 in PHY driver (7 nm predates 4 nm).
- The new CSI2 PHY driver does not support DPHY split mode, so the
Pixel 4 follower OV7251 (one of the two sensors sharing CSIPHY1) is
disabled in this series. A separate patchset adding split-mode support
to mainline OV7251 driver is planned.
- Link to v2: https://patch.msgid.link/20261106-sm8150-v7.4-rc1-camss-v2-0-39ee37787b00@andrewgigena.dev
Changes in v2:
- Address the review comments from Sashiko, Bryan and Val.
- Drop the internal CAMCC *_src clocks from the binding, the example and
the DTS; the binding now lists 27 clocks instead of 42.
- Remove clock-lanes from the CSI endpoints and use an unnumbered
endpoint in the example, matching the other CAMSS bindings.
- Describe vdda-phy-supply as 0.88V and vdda-pll-supply as 1.2V.
- Move the CSIPHY supplies from the CSID resources to the CSIPHY
resources, so they are enabled before the PHY is accessed.
- Add a separate fix for the VFE lite clock rates
- Tidy the CAMSS_8150 switch ordering.
- Link to v1: https://patch.msgid.link/20261104-sm8150-v7-4-rc1-camss-v1-0-7a9534a9a22f@andrewgigena.dev

Document the Qualcomm SM8150 Camera Subsystem. The IP integrates four
CSIPHY, four CSID (two full and two lite), two VFE and two VFE-Lite
instances, with 19 clocks, 8 interrupts, eight IOMMU streams, four
interconnect paths and three power domains.
The CSIPHY I/O spaces are not part of the CAMSS container device: each
CSIPHY is driven by the dedicated qcom,sm8150-csi2-phy driver, so this
binding only describes the VFE and CSID resources. Each CSI input port
is described with data lanes starting at 1, as required by the CAMSS
PHY mode.
Describe SM8150 in a dedicated schema instead of reusing another SoC's
schema.

Document the Qualcomm SM8150 MIPI CSI2 D-PHY. The PHY sits between the
CSI2 sensor and the CAMSS CSI decoder and is fed by the CSIPHY "core" and
"timer" clocks, the TITAN top power domain and the vdda-phy/vdda-pll
supplies.
Unlike the X1E80100 C-PHY/D-PHY combo PHY, SM8150 only has a D-PHY, has
no separate AHB clock and no MMCX/MX power domains, so describe it in a
dedicated schema.

From: Andrew Gigena <mail@andrewgigena.dev>
vfe_match_clock_names() builds the expected lite clock name from
vfe->id, but vfe->id is the index of the VFE in the resources array.
On SoCs where the lite VFEs come after the full VFEs, the generated
name is vfe_lite2, vfe_lite3, ... and never matches the actual
vfe_lite0/vfe_lite1 clocks, so their rates are never programmed.
Restrict the new prefix match to numbered "vfe_liteN" clocks (digit
check) to avoid matching aux clocks, leaving the pre-existing
vfe_lite_name and bare "vfe_lite" matches unchanged.
This affects SM8150, SC7280 and SC8280XP. On a Pixel 4 (SM8150),
streaming through VFE-lite0 left cam_cc_ife_lite_0_clk at 19.2 MHz and
failed with "VFE reset timeout".

From: Andrew Gigena <mail@andrewgigena.dev>
Add CAMSS platform data for the Qualcomm SM8150 SoC. The camera
subsystem contains four CSIPHY, four CSID (two full and two lite), two
VFE and two VFE-Lite instances.
The hardware reuses the existing 3-phase 1.0 CSIPHY, Gen2 CSID and
VFE 17x implementations; the CSIPHY uses the SC8280XP lane register
layout. Add CAMSS_8150 to the version enum and to the shared code
paths, then add the per-block clock, regulator, power domain,
interrupt and interconnect resources.
The CSIPHY resources are reduced to id/hw_ops/formats only; clocks,
regulators, registers and interrupts are owned by the dedicated CSI2
PHY driver.

From: Andrew Gigena <mail@andrewgigena.dev>
Add SM8150 platform data to the CSI2 DPHY driver so that SM8150 can use
the dedicated PHY driver instead of the CAMSS-integrated CSIPHY.
The SM8150 CSIPHY uses the SC8280XP lane register layout, as already
used by the CAMSS driver, so reuse that table, dropping the DNP entries,
which the new PHY driver does not program. The PHY is fed by the "core"
and "timer" clocks, the vdda-phy and vdda-pll supplies, and the Titan top
power domain, which is not scaled.
The timer clock is pinned to 300 MHz via a new timer_rate_hz soc field
(SM8150 timer only supports 19.2/300 MHz). SM8150 is ordered before
X1E80100 as it predates it (7 nm vs 4 nm). A detach of the
platform-attached single power domain is done before attaching by name,
so single-domain SoCs do not fail with -EEXIST.

From: Andrew Gigena <mail@andrewgigena.dev>
Describe the SM8150 CAMSS block and its CSID, VFE and VFE-Lite
instances, together with the four dedicated CSI2 PHYs, the two CCI
controllers and their I2C buses.
The CAMSS node exposes four CSI input ports, each linked to one
CSI2 PHY output port, and references the CAMCC clocks and GDSCs, the
interconnects and the IOMMU streams. Each of the four CSIPHY I/O
spaces is described by its own qcom,sm8150-csi2-phy node, fed by the
CSIPHY clocks and the Titan top power domain; the vdda-phy and
vdda-pll supplies are board-specific. The CCI nodes describe the
CCI0/CCI1 I2C buses, and the TLMM pinctrl states for their clock and
data lines are added to the existing pin controller node.
All new nodes are left disabled. The PHY supplies and the sensor
wiring are board-specific, so they belong in the board DTS that
enables the controller.

very much appreciated for changing the CAMSS phys to this format.
Please double check if SM8150 CSIPHY v1.1 is capable of C-PHY:
* https://git.codelinaro.org/clo/la/kernel/msm-4.14/-/blob/LA.UM.8.1.r1-16600-sm8150.0/drivers/media/platform/msm/camera/cam_sensor_module/cam_csiphy/cam_csiphy_soc.c#L239-256
D-PHY combo mode is also supported on the CSIPHY apparently.
Likely these features are supported on SM8150.

In downstream camcc-sm8150.c, PLL0 is on MX, and PLL0 supplies CSIPHY
clocks. I believe MX shall be added to the list of 'power-domains'.

Still it would be preferred to get 'vdda-0p9-supply' and 'vdda-1p2-supply'
properties.

Back to downstream

D-PHY combo mode is also supported on the SM8150 CSIPHY apparently,
it shall be reflected in a way that two endpoints could be present.

In general the change looks good, thank you, but likely it can be embedded
into the scheme for X1E.

That's an intermix of names, and you will get a review comment from
Krzysztof about it, I stand aside.

Drop 'cam_' prefix and 'cam_sf_0_mnoc' also.

Or C-PHY, right?..
In fact you shall drop bus-type from here, because the link between
CAMSS and PHY's output is not a CSI-2 bus, it makes it inapplicable.
'bus-type' is needed only between CSIPHY and a sensor connected to it.

that series.
