This patch fix the error handling in tb10x_pinctrl_probe(): - devm_ioremap_resource() return ERR_PTR() and never return NULL - remove the dev_err call to avoid redundant error message - pinctrl_register() returns NULL not ERR_PTR() Signed-off-by:

The gpio interrupt controller on Rockchip socs can do edge triggers only for single edges but not both. Nevertheless a lot of gpio users rely on the availability of both-edge triggered interrupts - i.e. gpio-keys. Therefore implement a solution similar to pinctrl-coh901 re-setting the triggering edge depending on the gpio value in the interrupt demuxer. Signed-off-by:

Besides the pull registers sitting in a separate place, the rk3188 also has the peculiarity that the pull registers of the first bank are split and the first half is sitting in the register space of the pmu. Therefore this adds a special bank-type for the first bank, to handle the two register sources. Signed-off-by:

The check limiting bias options to supported ones is already done thru rockchip_pinconf_pull_valid. Therefore this check is redundant and can be removed. Signed-off-by:

There are Rockchip SoCs, namely the rk3188, that combine a set of regular banks with banks that need special handling for some settings. Therefore add the possibility for the driver to handle more than one bank type. Signed-off-by:
-
Heiko Stübner authored
Further investigation of the different Rockchip SoCs showed that the differences especially in the pull settings are quite deep. As further patches will show, the register layout for the pulls of the rk3188 is quite strange. Also it is to assume, that later Rockchip SoCs may introduce even more quirks in this regard, making it hard to support all of those using the current generic pull_* variables. Therefore move the driver to hold the type of controller in an enum and do the handling according to it in the necessary places. Also instead of calculating the register in the get and set pull functions move it to a type-specific callback. Signed-off-by:

The AS3722 is a compact system PMU suitable for mobile phones, tablets etc. Add a driver to support accessing the GPIO, pinmux and pin configuration of 8 GPIO pins found on the ams AS3722 through pin control driver and gpiolib. The driver will register itself as the pincontrol driver and gpio driver. Signed-off-by:

While commit e1641531 (pinctrl: imx: move hard-coding data into device tree) moves to use DTC macro for imx pinctrl device tree setting, it changes the semantics of fsl,pins without updating the bindings doc properly. Let's update the fsl,pins description to stop confusing people. While at it, the example in the document is updated, and the stale TODO gets removed. Signed-off-by:
