[PATCH v3 0/8] pinctrl: Add T-Head TH1520 SoC pin controllers

From: Drew Fustini
Date: Mon Sep 30 2024 - 15:51:21 EST


This adds a pin control driver created by Emil for the T-Head TH1520
RISC-V SoC used on the Lichee Pi 4A and BeagleV Ahead boards and updates
the device trees to make use of it.

Changes in v3:
- Add Rb from Rob for the binding
- Rebase on 6.12-rc1 which enables AP_SUBSYS clock controller in dts
- Update dts to use AP_SUBSYS clock controller instead of fixed clocks
- Remove unneeded defines from the driver for dt unit addresses
- Link to v2: https://lore.kernel.org/linux-riscv/20240914-th1520-pinctrl-v2-0-3ba67dde882c@xxxxxxxxxxxxxxx/

Changes in v2:
- Add thead,pad-group device tree property
- Change driver to use the thead,pad-group property instead of the unit
address to identify the pad group of the pin controller being probed
- Return -EINVAL if no pin group can be determined during probe. In v1,
there was a bug that instead returned an unitialized variable
- Link to v1: https://lore.kernel.org/r/20240902-th1520-pinctrl-v1-0-639bf83ef50a@xxxxxxxxxxxxxxx
