Merge patch series "pinctrl: add support of Airoha SoCs"
Mikhail Kshevetskiy <[email protected]> says:
This patch series add pin controller and gpio driver support for EN7523/
AN7581/AN7583 SoCs. The driver based on official linux airoha pinctrl
and gpio driver with Matheus Sampaio Queiroga changes.
The original Matheus Sampaio Queiroga driver can be taken from the repo:
https://sirherobrine23.com.br/airoha_en7523/kernel/src/branch/airoha_en7523_pinctrl
Additionally in the EN7523 case the patches removes existing gpio dts
nodes and replaces them with pinctrl node. It should not be very
dangerous, because:
* No official EN7523 gpio support present in U-Boot
* Legacy Linux EN7523 GPIO driver is mostly abandoned
* The same driver is planned for upstream linux/openwrt
This patchset includes bitfield.h patches created for Linux kernel by
Geert Uytterhoeven. It suits U-Boot fine. I preserve original author and
original commit messages. Please note me, if there is a better way.
The patches were tested on EN7523/AN7581/AN7583 boards.
