This patchset adds Pin controller driver support for Meson-A1 Soc which shares the same register layout of pinmux with previous Meson-G12A, however there is difference for gpio and pin config registers in A1. Note that since dt-binding patch has been removed from this patch set, compiling need header file in patch 1 of [3]. Changes since v5 at [4] - modify return value when meson_map_resource return err or null for gpio/mux in meson_pinctrl_parse_dt. Changes since v4 at [3] - remove dt-binding patch for it can be merged first according to Linus Walleij's suggestion. - make SoCs before g12a share the same aobus dt paser function - make A1 dt paser function also as common part for later chip will re-use this definition. - modify meson_map_resource return value Changes since v3 at [2] - separate ao fixup from meson_pinctrl_parse_dt - provide ao extra dt parse callback for each SoC Changes since v2 at [1]: - make dt parser callback as a separate patch Changes since v1 at [0]: - collect Reviewed-by - modify commit log - add an extra dt parser function for a1 [0] https://lore.kernel.org/linux-amlogic/1568700442-18540-1-git-send-email-qianggui.song@xxxxxxxxxxx/ [1] https://lore.kernel.org/linux-amlogic/1570532999-23302-1-git-send-email-qianggui.song@xxxxxxxxxxx/ [2] https://lore.kernel.org/linux-amlogic/1571050492-6598-1-git-send-email-qianggui.song@xxxxxxxxxxx/ [3] https://lore.kernel.org/linux-amlogic/1572004167-24150-1-git-send-email-qianggui.song@xxxxxxxxxxx/ [4] https://lore.kernel.org/linux-amlogic/1573203636-7436-1-git-send-email-qianggui.song@xxxxxxxxxxx/ Qianggui Song (3): pinctrl: meson: add a new callback for SoCs fixup pinctrl: meson: add pinctrl driver support for Meson-A1 SoC arm64: dts: meson: a1: add pinctrl controller support arch/arm64/boot/dts/amlogic/meson-a1.dtsi | 18 + drivers/pinctrl/meson/Kconfig | 6 + drivers/pinctrl/meson/Makefile | 1 + drivers/pinctrl/meson/pinctrl-meson-a1.c | 942 +++++++++++++++++++++++++++++ drivers/pinctrl/meson/pinctrl-meson-axg.c | 1 + drivers/pinctrl/meson/pinctrl-meson-g12a.c | 9 + drivers/pinctrl/meson/pinctrl-meson-gxbb.c | 1 + drivers/pinctrl/meson/pinctrl-meson-gxl.c | 1 + drivers/pinctrl/meson/pinctrl-meson.c | 38 +- drivers/pinctrl/meson/pinctrl-meson.h | 7 + drivers/pinctrl/meson/pinctrl-meson8.c | 1 + drivers/pinctrl/meson/pinctrl-meson8b.c | 1 + 12 files changed, 1017 insertions(+), 9 deletions(-) create mode 100644 drivers/pinctrl/meson/pinctrl-meson-a1.c -- 1.9.1
