[PATCH v3 00/12] riscv: Allwinner D1/D1s platform support

Thu Dec 8 01:02:25 PST 2022

This series adds the Kconfig/defconfig plumbing and devicetrees for a
range of Allwinner D1 and D1s-based boards. Many features are already
enabled, including USB, Ethernet, and WiFi.

The devicetrees use bindings from the following series which have not
yet been merged to linux-next:
 - In-package LDO regulators:
   https://lore.kernel.org/lkml/20221208084127.17443-1-samuel@sholland.org/
 - Ethernet MAC binding fix (not a new issue with D1):
   https://lore.kernel.org/lkml/20221208061616.7806-1-samuel@sholland.org/
 - TI ADC101C ADC (accepted, not yet in linux-next):
   https://lore.kernel.org/lkml/20221125220903.8632-1-samuel@sholland.org/

The only remaining DT validation issue is that gpio-fan is missing a
YAML conversion, although one is on the list here:

Note that validation requires dt-schema v2022.12 or newer.

I tested this series (DMIC, Ethernet, LEDs, MMC, PMIC, touch, and USB,
all where available) on the following boards:
 - sun20i-d1-devterm-v3.14
 - sun20i-d1-dongshan-nezha-stu
 - sun20i-d1-lichee-rv-86-panel-480p
 - sun20i-d1-mangopi-mq-pro
 - sun20i-d1-nezha
 - sun20i-d1s-mangopi-mq

Changes in v3:
 - Drop dummy DCXO clock-frequency property
 - Decrease the PLIC's riscv,ndev property to 175
 - Fix `make W=1 dtbs` warnings (unnecessary #address/#size-cells)
 - Drop mmc aliases
 - Change LED_FUNCTION_BACKLIGHT to LED_FUNCTION_STATUS (the backlight
   regulator is disconnected by default, so this is a standalone LED)
 - Fix `make W=1 dtbs` warnings (missing reg properties)
 - ARCH_SUNXI depends on MMU && !XIP_KERNEL

Changes in v2:
 - Add MangoPi MQ (non-Pro) board
 - Split into separate files for sharing with D1s/R528/T113
 - Use SOC_PERIPHERAL_IRQ macro for interrupts
 - Rename osc24M to dcxo and move the frequency to the board DTs
 - Drop analog LDOs due to the missing binding
 - Correct tcon_top DSI clock reference
 - Add DMIC, DSI controller, and DPHY (bindings are in linux-next)
 - Add CPU OPP table
 - Common regulators moved to MangoPi MQ patch, removed analog LDOs
 - Removed LRADC (depends on analog LDOs)
 - Added XR829 host-wake interrupt
 - Added DMIC sound card to Lichee RV dock and Lichee RV 86 Panel
 - Removed LRADC (depends on analog LDOs)
 - Added LED (GPIO shared between onboard LED and backlight regulator)
 - Added PMIC GPIO controller node (binding merged for 6.2)
 - Sort Kconfig as if we had done s/SOC_/ARCH_/ for future-proofing
