[U-Boot] [PATCH V3 0/4] Fix fdt 'reg' parsing and unbreak few Exynos4 boards

[Przemyslaw Marczak]

Booting of Odroid U3/X2 with SD card, ends with error:

MMC:   EXYNOS DWMMC: 0
Card did not respond to voltage select!
*** Warning - MMC init failed, using default environment

Generally this was broken, because of wrong addresses,
assigned to GPIOs.
The source of the problem was in rework of lib/fdtdec.c, after which
function fdtdec_get_addr() doesn't work as previous and function
dev_get_addr() doesn't works as expected.

The code after rework in lib/fdtdec.c assumed, that #size-cells property,
should be always greater or equal to 1, this was wrong, because it can be 0.

In case of debugging the issue, I found, that mmc clock was computed wrong,
for Exynos4, because of function get_mmc_clk(), which always returns -1 for
this SoC.

The patchset should fix booting on all Exynos4 boards, however it was tested
on: Odroid X2 / U3 / XU3 and Trats / Trats2.

Przemyslaw Marczak (4):
  fdtdec: fix parsing 'reg' property with zero value in '#size-cells'
  gpio: s5p: call: dev_get_addr() instead of fdtdec_get_addr()
  mach-exynos: clock: restore calling dead exynos4_get_mmc_clk()
  trats: fdt: disable unused DW MMC
