Mikhail Kshevetskiy <mikhail.kshevetskiy@iopsys.eu> 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.
