* pinctrl: add driver for rk3399Kever Yang2016-09-22-0/+440

* rockchip: rk3288: Fix pinctrl for GPIO bank 0John Keeping2016-07-31-2/+19
| | | | | | | | | | | | | | | | Bank 0 is the "PMU GPIO" bank which is controlled by the PMU registers rather than the GRF registers. In the GRF the top half of the register is used as a mask so that some bits can be updated without affecting the others, but in the PMU this feature is not provided and the top half of the register is reserved. Take the same approach as the Linux driver to update the value via read-modify-write but setting the mask for only the bits that have changed. The PMU registers ignore the top 16 bits so this works for both GRF and PMU iomux registers. Signed-off-by: John Keeping <john@metanate.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
* dm: Use dm_scan_fdt_dev() directly where possibleSimon Glass2016-07-27-17/+4
| | | | | | | Quite a few places have a bind() method which just calls dm_scan_fdt_dev(). We may as well call dm_scan_fdt_dev() directly. Update the code to do this. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()Simon Glass2016-07-27-5/+2
| | | | | | | This new function is more convenient for callers, and handles pre-relocation situations automatically. Signed-off-by: Simon Glass <sjg@chromium.org>
* cosmetic: rockchip: sort socs according to numbersHeiko Stübner2016-07-25-1/+1
| | | | | | | | | | Having some sort of ordering proofed helpful in a lot of other places already. So for a larger number of rockchip socs it might be helpful as well instead of an ever increasing unsorted list.

* cosmetic: rockchip: rk3036: pinctrl: fix config symbol namingHeiko Stübner2016-07-25-1/+1
| | | | | | | | | Rockchip socs are always named rkxxxx in all places, as also shown by the naming of the rk3036 pinctrl file itself. Therefore also name the config symbol according to this scheme. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Simon Glass <sjg@chromium.org>
* cosmetic: rockchip: rk3288: pinctrl: fix config symbol namingHeiko Stübner2016-07-25-1/+1
| | | | | | | | The rk3288 pinctrl is very specific to this soc, so should not hog the generic rockchip naming. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Acked-by: Simon Glass <sjg@chromium.org>
* rockchip: pinctrl: Update the rk3288 driver to support of-platdataSimon Glass2016-07-14-1/+7
| | | | | | | | Add support for of-platdata with rk3288. This requires disabling access to the device tree and renaming the driver to match the string that of-platdata will search for. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: rk3288: pinctrl: support more pinsSjoerd Simons2016-05-27-1/+1
| | | | | | | | | The rgmii_pins node in rk3288.dtsi configures 15 pins. Increase the size of the cell array to accomedate that, otherwise only the first 10 get configured. Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Reviewed-by: Simon Glass <sjg@chromium.org>
* rockchip: rk3288: pinctrl: Fix HDMI pinctrlSimon Glass2016-01-21-0/+2
| | | | | | | Since the device tree does not specify the EDID pinctrl option for HDMI we must set it manually. Fix the driver to handle this. Signed-off-by: Simon Glass <sjg@chromium.org>

* rockchip: pinctrl: Add a full pinctrl driverSimon Glass2016-01-21-1/+229
| | | | | | | We can make use of the device tree to configure pinctrl settings. Add this support for the driver so we can use it in U-Boot proper. Signed-off-by: Simon Glass <sjg@chromium.org>
* rockchip: Convert the PMU IOMUX registers into an arraySimon Glass2016-01-21-2/+2
| | | | | | | | | This is easier to deal with when using generic code since it allows us to use a register index instead of naming each register. Adjust it, adding an enum to improve readability. Signed-off-by: Simon Glass <sjg@chromium.org>

* pinctrl: move dm_scan_fdt_node() out of pinctrl uclassMasahiro Yamada2015-09-19-0/+8
| | | | | | | | | | | | | | | | | | | | | Commit c5acf4a2b3c6 ("pinctrl: Add the concept of peripheral IDs") added some additional change that was not mentioned in the git-log. That commit added dm_scan_fdt_node() in the pinctrl uclass binding. It should be handled by the simple-bus driver or the low-level driver, not by the pinctrl framework. I guess Simon's motivation was to bind GPIO banks located under the Rockchip pinctrl device. It is true some chips have sub-devices under their pinctrl devices, but it is basically SoC-specific matter. This commit partly reverts commit c5acf4a2b3c6 to keep the only pinctrl-generic features in the uclass. The dm_scan_fdt_node() should be called from the rk3288_pinctrl driver.
