[PATCH v2 00/10] riscv: Add FPIOA and GPIO support for Kendryte K210

[Sean Anderson]

This patch series adds support for pinmuxing, gpios, and leds on the Kendyte
K210.

This patch series was previously part of

This patch series depends on
https://patchwork.ozlabs.org/project/uboot/list/?series=178480

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

Sean Anderson (10):
  pinctrl: Add pinmux property support to pinctrl-generic
  test: pinmux: Add test for pin muxing
  pinctrl: Add support for Kendryte K210 FPIOA
  gpio: sifive: Use generic reg read function
  gpio: dw: Fix warnings about casting int to pointer
  gpio: dw: Add a trailing underscore to generated name
  gpio: dw: Return output value when direction is out
  led: gpio: Default to using node name if label is absent
  riscv: Add pinmux and gpio bindings for Kendryte K210
  riscv: Add FPIOA and GPIO support for Kendryte K210
