This patch series adds support for pinmuxing, gpios, and leds on the Kendyte
K210.
This patch series was previously part of
https://patchwork.ozlabs.org/project/uboot/list/?series=161576
This patch series depends on
https://patchwork.ozlabs.org/project/uboot/list/?series=178480
Changes in v5:
- Increase CONSOLE_LOGLEVEL to 5 as a hack to get the board booting again
- Patch 05/12 "gpio: sifive: Use generic reg read function" has been superseded
by commit 2548493ab4.
- Rebase onto u-boot/master
Changes in v4:
- Add sandbox dt-binding headers to MAINTAINERS
- Add test for led behavior
- Add test/dm/pinmux.c to patch
- Move sandbox_* variables into a priv structure. This resets them to the
default state every time we re-probe.
- Reformat documentation in dm/pinctrl.h
Changes in v3:
- Add dt-bindings/pinctrl/sandbox-pinmux.h to patch
Changes in v2:
- Add test for pinmuxing
- Don't clear existing pinctrl settings on probe
- Re-order GPIOs to match the defaults more closely
- Rebase onto v13 of "riscv: Add Sipeed Maix support"
- Rewrite FPIOA driver to use pinmux property
- Support muxing the output enable signal for each function in the FPIOA
- Support output and input inversion in the pinmux driver
- Support pinmux property in pinctrl-generic
