70f7a2cdac rockchip: rk3288: pinctrl: support more pins
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.

318922b30f rockchip: rk3288: pinctrl: Fix HDMI pinctrl
Since the device tree does not specify the EDID pinctrl option for HDMI we
must set it manually. Fix the driver to handle this.

Implement this so that the GPIO command will be able to report whether a
GPIO is used for input or output.

This file has many features that are not needed by SPL. Use #ifdef to
remove the unused features and reduce the code size.

bea705c993 rockchip: pinctrl: Add a full pinctrl driver
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.

a4275f5e52 rockchip: Convert the PMU IOMUX registers into an array
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.

8a5f6129d1 pinctrl: move dm_scan_fdt_node() out of pinctrl uclass
Commit c5acf4a2b3 ("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 c5acf4a2b3 to keep the only
pinctrl-generic features in the uclass.  The dm_scan_fdt_node()
should be called from the rk3288_pinctrl driver.
