* pinctrl: tree-wide probe devices during core_initcallMarco Felsch2018-10-191-1/+1
| | | | | | | | | | | | | Since commit 37e6bee7e5 ("gpiolib: Add support for GPIO "hog" nodes") barebox can handle hog-gpios. To work correctly the pinctrl driver must be initialised first. Reorder all pinctrl drivers so they will be called first. find drivers/pinctrl/ -type f -name *.c \ -exec sed -i 's/\bpostcore_initcall\b/core_initcall/' "{}" +; Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

* pinctrl: tegra: try to select "boot" stateLucas Stach2014-11-041-2/+6
| | | | | | | | | | New DTs call the initial pinctrl state "boot" in order to avoid Linux reconfiguring the pinctrl by default. The bootloader should explicitly set this state. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* tegra20: add pinctrl driverLucas Stach2013-05-121-0/+346
This adds a pinctrl driver for the Tegra 20 line of SoCs. It only supports the three basic pinconfiguration settings function mux, tristate control and pullup/down control. The driver understands the same devicetree bindings as the Linux one, unimplemented pinconfiguration options will be ignored.
