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 <narmstrong@baylibre.com> Tested-by: Peter Rosin <peda@axentia.se> Acked-by: Rob Herring <robh@kernel.org> ested-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
