[PATCH v2 0/2] add support for Theobroma Systems PX30-µQ7 (Ringneck) with Haikou devkit

[PATCH v2 0/2] add support for Theobroma Systems PX30-µQ7 (Ringneck) with Haikou devkit

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz@theobroma-systems.com>

The PX30-uQ7 (Ringneck) SoM is a µQseven-compatible (40mmx70mm, MXM-230
connector) system-on-module from Theobroma Systems[1], featuring the
Rockchip PX30.

It provides the following feature set:
* up to 4GB DDR4
* up to 128GB on-module eMMC (with 8-bit 1.8V interface)
* SD card (on a baseboard) via edge connector
* Fast Ethernet with on-module TI DP83825I PHY
* MIPI-DSI/LVDS
* MIPI-CSI
* USB
- 1x USB 2.0 dual-role
- 3x USB 2.0 host
* on-module STM32 Cortex-M0 companion controller, implementing:
- low-power RTC functionality (ISL1208 emulation)
- fan controller (AMC6821 emulation)
- USB<->CAN bridge controller
* on-module Espressif ESP32 for Bluetooth + 2.4GHz WiFi
* on-module NXP SE05x Secure Element

[1] https://www.theobroma-systems.com/som-product/px30-%C2%B5q7/

The Espressif ESP32 support is not added in this patch series as
there'll be some challenges around the Device Tree bindings that will
require its own patch series and discussion.

MIPI-DSI/CSI "consumers" will come later with an adapter board once it
is designed.

Cheers,
Quentin

v2:
 - changed GPIO used for sleep and wake buttons since v1.2 HW rework (v1.1 was
   engineering sample),
 - changed GPIO used for PHY reset since v1.2 HW rework (v1.1 was engineering
   sample),
 - enabled saradc used for module voltage feedback and module HW version identifier,
 - updated vccio_sd for 1.8V-3.3V operation instead of forced 3V,
 - enabled SDR12, SDR25 and SDR50 for SD card controller,
 - added vqmmc supply for SD card controller,
 - removed SW_BOOT_ALT addition to the input SW events in favor of a GPIO input
   hog,
 - renamed model property in DT to use u instead of µ since dtc didn't like it,
 - renamed haikou-keys DT node name into gpio-keys to match DT standard
   expectation,
 - renamed gpio-keys entries with lowercase and dash characters only,
 - added button- or switch- prefix for gpio-keys,
 - removed label for GPIO LEDs in favor of function and color properties,
 - renamed regulator DT node names to be suffixed with -regulator as per DT
   standard expectation,
 - added GPIO hog for BIOS_DISABLE/BOOT_ALT override pin (makes sure that the
   lines to eMMC and SPI-flashes are working even if the hardware switch
   disabled them at boot),
 - renamed pmic_int DT node name into pmic-int,
 - removed a couple of redundant status = okay,
 - added Acked-By for dt-bindings,
 - replaced µ with u in dt-bindings description just for consistency,
