pinctrl driver for MT7622 SoC + +Add support for pinctrl on MT7622 SoC. The IO core found on the SoC has +the registers for pinctrl, pinconf and gpio mixed up in the same register +range. However, the IO core for the MT7622 SoC is completely distinct from +anyone of previous MediaTek SoCs which already had support, such as +the hardware internal, register address map and register detailed +definition for each pin. + +Therefore, instead, the driver is being newly implemented by reusing +generic methods provided from the core layer with GENERIC_PINCONF, +GENERIC_PINCTRL_GROUPS, and GENERIC_PINMUX_FUNCTIONS for the sake of code +simplicity and rid of superfluous code. Where the function of pins +determined by groups is utilized in this driver which can help developers +less confused with what combinations of pins effective on the SoC and even +reducing the mistakes during the integration of those relevant boards. + +As the gpio_chip handling is also only a few lines, the driver also +implements the gpio functionality directly through GPIOLIB. + +Signed-off-by: Sean Wang <sean.wang@mediatek.com> +Reviewed-by: Biao Huang <biao.huang@mediatek.com> +Signed-off-by: Linus Walleij <linus.walleij@linaro.org> +--- + drivers/pinctrl/Makefile | 2 +- + drivers/pinctrl/mediatek/Kconfig | 10 + + drivers/pinctrl/mediatek/Makefile | 3 +- + drivers/pinctrl/mediatek/pinctrl-mt7622.c | 1595 +++++++++++++++++++++++++++++ + 4 files changed, 1608 insertions(+), 2 deletions(-) + create mode 100644 drivers/pinctrl/mediatek/pinctrl-mt7622.c + +diff --git a/drivers/pinctrl/Makefile b/drivers/pinctrl/Makefile +index c16e27900dbb..3a798d5b0900 100644 +--- a/drivers/pinctrl/Makefile ++++ b/drivers/pinctrl/Makefile +@@ -63,5 +63,5 @@ obj-$(CONFIG_PINCTRL_SUNXI) += sunxi/ + obj-y += ti/ + obj-$(CONFIG_PINCTRL_UNIPHIER) += uniphier/ + obj-$(CONFIG_ARCH_VT8500) += vt8500/ +-obj-$(CONFIG_PINCTRL_MTK) += mediatek/ ++obj-y += mediatek/ + obj-$(CONFIG_PINCTRL_ZX) += zte/ +diff --git a/drivers/pinctrl/mediatek/Kconfig b/drivers/pinctrl/mediatek/Kconfig +index 03b3023d5fe5..3e598740b379 100644 +--- a/drivers/pinctrl/mediatek/Kconfig ++++ b/drivers/pinctrl/mediatek/Kconfig +@@ -32,6 +32,16 @@ config PINCTRL_MT8127 + select PINCTRL_MTK + + # For ARMv8 SoCs ++config PINCTRL_MT7622 ++ bool "MediaTek MT7622 pin control" ++ depends on OF ++ depends on ARM64 || COMPILE_TEST ++ select GENERIC_PINCONF ++ select GENERIC_PINCTRL_GROUPS ++ select GENERIC_PINMUX_FUNCTIONS ++ select GPIOLIB ++ select OF_GPIO ++ + config PINCTRL_MT8173 + bool "Mediatek MT8173 pin control" + depends on OF +diff --git a/drivers/pinctrl/mediatek/Makefile b/drivers/pinctrl/mediatek/Makefile +index e59c613d4ddd..6e3ca6bbda7a 100644 +--- a/drivers/pinctrl/mediatek/Makefile ++++ b/drivers/pinctrl/mediatek/Makefile +@@ -1,9 +1,10 @@ + # Core +-obj-y += pinctrl-mtk-common.o ++obj-$(CONFIG_PINCTRL_MTK) += pinctrl-mtk-common.o + + # SoC Drivers + obj-$(CONFIG_PINCTRL_MT2701) += pinctrl-mt2701.o + obj-$(CONFIG_PINCTRL_MT8135) += pinctrl-mt8135.o + obj-$(CONFIG_PINCTRL_MT8127) += pinctrl-mt8127.o ++obj-$(CONFIG_PINCTRL_MT7622) += pinctrl-mt7622.o + obj-$(CONFIG_PINCTRL_MT8173) += pinctrl-mt8173.o + obj-$(CONFIG_PINCTRL_MT6397) += pinctrl-mt6397.o +diff --git a/drivers/pinctrl/mediatek/pinctrl-mt7622.c b/drivers/pinctrl/mediatek/pinctrl-mt7622.c +new file mode 100644 +index 000000000000..3824d82888ac +--- /dev/null ++++ b/drivers/pinctrl/mediatek/pinctrl-mt7622.c +@@ -0,0 +1,1595 @@ ++/* ++ * MediaTek MT7622 Pinctrl Driver ++ * ++ * Copyright (C) 2017 Sean Wang <sean.wang@mediatek.com> ++ * ++ * This program is free software; you can redistribute it and/or modify ++ * it under the terms of the GNU General Public License version 2 as ++ * published by the Free Software Foundation. ++ * ++ * This program is distributed in the hope that it will be useful, ++ * but WITHOUT ANY WARRANTY; without even the implied warranty of ++ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
