95ce385a4a dm: core: Add uclass_first/next_device_check()
Sometimes it is useful to iterate through all devices in a uclass and
skip over those which do not work correctly (e.g fail to probe). Add two
new functions to provide this feature.

The caller must check the return value each time to make sure that the
device is valid. But the device pointer is always returned.

Add support for the gmac ethernet interface to pinctrl. This hardcodes

fe450895ff rockchip: pinctrl: rk3328: use gpio instead of sdmmc-pwren
SDMMC-PWREN is a pin to control voltage for SDMMC IO, it may
be high active or low active, the dwmmc driver always assume
the sdmmc-pwren as high active.

Kernel treat this pin as fixed regulator instead of a pin from
controller, and then it can set in dts file upon board schematic,
that's a good solution, we can also do this in u-boot.

bafcf2db41 rockchip: Add basic support for phyCORE-RK3288 SoM based carrier board
The phyCORE-RK3288 is a SoM (System on Module) containing a RK3288 SoC.
The module can be connected to different carrier boards.
It can be also equipped with different RAM, SPI flash and eMMC variants.
The Rapid Development Kit option is using the following setup:

  - 1 GB DDR3 RAM (2 Banks)
  - 1x 4 KB EEPROM
  - DP83867 Gigabit Ethernet PHY
  - 16 MB SPI Flash
  - 4 GB eMMC Flash

Add basic support for the PCM-947 carrier board, a RK3288 based development
board made by PHYTEC. This board works in a combination with
the phyCORE-RK3288 System on Module.

419b08012a Revert "mmc: dw_mmc: rockchip: select proper card clock"
The origin patch get rockchip dwmmc by name 'ciu', which lead
to the SPL not able to remove 'clock-names' node in dts.
I'm not saying this is not correct, but I would prefer to handle
this in dts or clock driver to save memory for SPL.
For example the rk3288 SPL size has out of memory if not enable
BACK_TO_BROM option, there are many other SoCs has less internal
memory than rk3288.

This reverts commit 480a9b834c.

3d40479f00 rockchip: ns16550: dm: convert fdt_get to dev_read
