[PATCH v2 2/2] arm64: dts: rockchip: Add FriendlyElec CM3588 NAS board

From: Sebastian Kropatsch
Date: Sun Jun 02 2024 - 18:20:45 EST

From: Sebastian Kropatsch <seb-dev@xxxxxx>

The CM3588 NAS by FriendlyElec pairs the CM3588 compute module, based on
the Rockchip RK3588 SoC, with the CM3588 NAS Kit carrier board.
To reflect the hardware setup, add device tree sources for the SoM and
the NAS daughter board as separate files.

Hardware features:
- Rockchip RK3588 SoC
- 4GB/8GB/16GB LPDDR4x RAM
- 64GB eMMC
- MicroSD card slot
- 1x RTL8125B 2.5G Ethernet
- 4x M.2 M-Key with PCIe 3.0 x1 (via bifurcation) for NVMe SSDs
- 2x USB 3.0 (USB 3.1 Gen1) Type-A, 1x USB 2.0 Type-A
- 1x USB 3.0 Type-C with DP AltMode support
- 2x HDMI 2.1 out, 1x HDMI in
- MIPI-CSI Connector, MIPI-DSI Connector
- 40-pin GPIO header
- 4 buttons: power, reset, recovery, MASK, user button
- 3.5mm Headphone out, 2.0mm PH-2A Mic in
- 5V Fan connector, PWM buzzer, IR receiver, RTC battery connector

PCIe bifurcation is used to handle all four M.2 sockets at PCIe 3.0 x1
speed. Data lane mapping in the DT is done like described in commit
f8020dfb311d ("phy: rockchip-snps-pcie3: fix bifurcation on rk3588").

This device tree includes support for eMMC, SD card, ethernet, all USB2
and USB3 ports, all four M.2 slots, GPU, RTC, buzzer, UART debugging as
well as the buttons and LEDs.
The GPIOs are labeled according to the schematics.

To differentiate if a node or property should be part of the SoM's
devicetree source or the carrier board's source, I used the official
schematics and documents available in FriendlyElec's wiki. [1-3]

Changes in v2 (this patch):
- split dts into two files (CM and carrier board)
- rename fixed regulators with preferred 'regulator-' prefix
- use preferred 'gpios' property instead of 'gpio'
- add 'pinctrl-names' property for every pinctrl
- add several pwm nodes
- drop HMDI PHY and VOP support
- drop unneeded &wdt node
- remove i2c4 since it's not availabe according to the schematics
- &sdhci: drop 'full-pwr-cycle-in-suspend' flag
- &sdmmc: drop 'cap-mmc-highspeed' flag because no-mmc is present
- &sdmmc: drop 'cd-gpios' property, unneeded w/ using sdmmc_det pinctrl *1
- &usb_host0_xhci, &usb_host2_xhci: remove default 'dr_mode' property

*1:
Some RK3588 boards are still using this property, the following quote
is from rk3588-tiger-haikou.dts for example:
&sdmmc {
/* while the same pin, sdmmc_det does not detect card changes */
cd-gpios = <&gpio0 RK_PA4 GPIO_ACTIVE_LOW>;

I am unsure as to whether this comment from the quote might apply for
the CM3588 as well. Please let me know if you are able to tell :-)
