From 9e80f9064e73f9f82679884ddf8b03ac3606cf4a Mon Sep 17 00:00:00 2001 From: Neil Armstrong Date: Fri, 21 Oct 2016 11:09:58 +0200 Subject: pinctrl: Add SX150X GPIO Extender Pinctrl Driver Since the I2C sx150x GPIO expander driver uses platform_data to manage the pins configurations, rewrite the driver as a pinctrl driver using pinconf to get/set pin configurations from DT or debugfs. The pinctrl driver is functionnally equivalent as the gpio-only driver and can use DT for pinconf. The platform_data confirmation is dropped. This patchset removed the gpio-only driver and selects the Pinctrl driver config instead. This patchset also migrates the gpio dt-bindings to pinctrl and add the pinctrl optional properties. The driver was tested with a SX1509 device on a BeagleBone black with interrupt support and on an X86_64 machine over an I2C to USB converter. This is a fixed version that builds and runs on non-OF platforms and on arm based OF. The GPIO version is removed and the bindings are also moved to the pinctrl bindings. Changes since v2 - rebased on v4.9-rc1 - removed MODULE_DEVICE_TABLE as in upstream bb411e771b0e ("gpio: sx150x: fix implicit assumption module.h is present") Changes since v1 - Fix Kconfig descriptions on pinctrl and gpio - Fix Kconfig dependency - Remove oscio support for non-789 devices - correct typo in dt bindings - remove probe reset for non-789 devices Changes since RFC - Put #ifdef CONFIG_OF/CONFIG_OF_GPIO to remove OF code for non-of platforms - No more rely on OF_GPIO config - Moved and enhanced bindings to pinctrl bindings - Removed gpio-sx150x.c - Temporary select PINCTRL_SX150X when GPIO_SX150X - Temporary mark GPIO_SX150X as deprecated Signed-off-by: Neil Armstrong Tested-by: Peter Rosin Acked-by: Rob Herring ested-by: Andrey Smirnov Signed-off-by: Linus Walleij --- drivers/gpio/Makefile | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/gpio/Makefile') diff --git a/drivers/gpio/Makefile b/drivers/gpio/Makefile index ab28a2daeacc..76c7af6c5839 100644 --- a/drivers/gpio/Makefile +++ b/drivers/gpio/Makefile @@ -102,7 +102,6 @@ obj-$(CONFIG_GPIO_SPEAR_SPICS) += gpio-spear-spics.o obj-$(CONFIG_GPIO_STA2X11) += gpio-sta2x11.o obj-$(CONFIG_GPIO_STMPE) += gpio-stmpe.o obj-$(CONFIG_GPIO_STP_XWAY) += gpio-stp-xway.o -obj-$(CONFIG_GPIO_SX150X) += gpio-sx150x.o obj-$(CONFIG_GPIO_SYSCON) += gpio-syscon.o obj-$(CONFIG_GPIO_TB10X) += gpio-tb10x.o obj-$(CONFIG_GPIO_TC3589X) += gpio-tc3589x.o -- cgit v1.2.3
