[PATCH v8 2/2] arm64: dts: rockchip: Add ALIENTEK QuarkPi-CA2

[Bob Hui <bg9oxa@163.com>]

Add a device tree for the ALIENTEK QuarkPi-CA2, an RK3588S based card
computer. The board comes in 4, 8 and 16 GiB LPDDR4X variants with
32 GB, 64 GB or 128 GB of eMMC; this was tested on the 16 GiB/128 GB
one.

Supported peripherals:
  - 2x LPDDR4X SDRAM and eMMC, plus the microSD card slot
  - RK806-1 PMIC with the full regulator tree
  - HDMI output up to 4K60, through hdptxphy0 and VOP2
  - Gigabit Ethernet with the YT8531 RGMII PHY on MDIO1
  - four USB Type-A ports (1x USB 3.0, 3x USB 2.0)
  - USB Type-C port with USB 3.0 and DP output, described through the
    USBDP PHY and DP0, with role switch and DP altmode
  - 3.5 mm headset jack (headphones + microphone) with the ES8388
    codec, the headphone amplifier and jack detection
  - three function keys (volume down, volume up and PWR_ON from the
    PMIC) and the headset hook button
  - IR receiver, 4-pin PWM fan connector and two LEDs
  - 3-wire debug UART (UART2)
  - 40-pin expansion header with UART5, I2C3, I2C5, SPI0 and PWM14
  - two 26-pin MIPI DSI and three 22-pin MIPI CSI connectors, with the
    connector I2C buses enabled (i2c4, i2c7); panels and cameras are
    described by overlays
  - M.2 E-key socket for a WiFi/BT module, with the PCIe 2.0 x1 link
    enabled (pcie2x1l2, combphy0_ps)
  - Mali GPU and the three NPU cores

The GbE MAC takes its reference clock from the PHY, and the PHY keeps its
clock output enabled while the link is down so that the MAC can be
initialised. The PHY adds the RGMII delays internally ("rgmii-id") while
the MAC adds none, and the MDIO bus is described through the SoC mdio1
controller with the PHY as its only child.

Tested on hardware: boot from eMMC with this DTB, gigabit Ethernet at
line rate with zero retransmissions, the USB-C port switching to host
mode with DP altmode on an attached display, the USB 3.0 Type-A port
with a SuperSpeed UAS disk, HDMI output on a monitor, ES8388 playback
on the 3.5 mm jack, jack detection, the ADC volume keys, the headset
hook button, the IR receiver and the PWM fan.

Notes on some of the less obvious choices:

* The codec is clocked through I2S0_8CH_MCLKOUT_TO_IO rather than the
internal I2S0_8CH_MCLKOUT mux. On RK3588 the MCLK-to-IO routing is a
gate in SYS_GRF SOC_CON6 which the bootloader leaves closed, so nothing
drives MCLK out to the codec; using the _TO_IO clock makes the codec
driver open that gate at probe, while assigned-clocks stays on the
internal mux to keep the 12.288 MHz rate.

* The codec compatible list is "everest,es8388", "everest,es8328", as
documented in everest,es8328.yaml and as used by the other boards with
this part.

* The 3.5 mm jack is fed from the codec outputs (LOUT1/ROUT1) and from
the on-board headphone amplifier, as in the vendor tree. The DAPM state
during playback shows LOUT1/ROUT1 each with two active consumers (the
amplifier and the jack), and describing only the amplifier path leaves
the jack silent (verified on hardware with a test tone and music).

* The USB 3.0 Type-A port is wired to usb_host2_xhci through combphy2_psu;
both are enabled here. combphy2_psu is free because the M.2 socket uses
pcie2x1l2 (combphy0_ps), so sata0 stays disabled - it shares that PHY.

* The USB-C port is a dual-role port: the connector carries data-role
"dual" and role-switch endpoints, the dwc3 uses usb-role-switch, and the
SBU lines are switched through the TCPC. The port also provides DP
altmode, described through the usbdp PHY and the DP output.

* The board also has a second Type-C connector used as a PD power input;
it is not described here. The reset and UPDATE buttons are not described
either: reset and power-on are handled by the RK806-1, and UPDATE is a
boot strap sampled at reset.

* The board has two 26-pin MIPI DSI and three 22-pin MIPI CSI connectors,
but no camera or panel is described here: those are plug-in modules.
Enabling the CSI-2 receiver without a sensor attached makes the driver
fail to find its endpoint at probe, so camera and panel descriptions
belong in overlays, as in the vendor tree. The I2C buses of the two DSI
connectors are enabled (i2c4, i2c7); the backlight PWMs (pwm5, pwm6) and
the MIPI DCPHYs are left to the same future overlay work.

* Analog capture does not work yet: the capture stream returns a constant
0xFFFF even though the codec's ADC and PGA paths power up, the input
muxes are enabled and the mic bias register bits are set. Comparing the
mainline es8328 driver with the vendor one shows that the vendor driver
carries an extra input-selection mux layer for the capture path, so this
is a driver-side limitation and not a problem with this description; it
will be submitted separately.

* The IR receiver uses the generic gpio-ir-receiver binding; no keymap is
set here because the remote shipped with the board has no upstream
rc-map entry yet.

* The two SPI0 chip selects are described as GPIOs (cs-gpios) instead of
muxing the dedicated SPI0_CS0_M3 / SPI0_CS1_M3 pins. Both chip select
lines are routed to the 40-pin expansion header, so they cannot stay
owned by the pinmux; with cs-gpios both of them are claimed by the SPI
core and remain usable from the header.

* A 500 MB transfer over the GbE port completed with zero retransmitted
segments (363427 segments) and rx_crc_errors staying at zero; the PHY
negotiates 1000 Mb/s full duplex and, once the link is up, the MAC delay
registers stay at zero as described above.
