[U-Boot] [PATCH 0/2] Revert changes to __of_translate_address()

[U-Boot] [PATCH 0/2] Revert changes to __of_translate_address()

[Przemyslaw Marczak]

Globally enabled CONFIG_OF_TRANSLATE causes, that function dev_get_addr()
returns a different result for a node with: 'size-cells = <0>'.

The above change, breaks the Exynos boards for a long time, because of GPIO
driver, which uses the fdt in a non standard way.

After sending few approaches with adding support for that case,
the one was appllied for a temporary fix for the release:

"fdt: fix address cell count checking in fdt_translate_address()"

However, after discussion on the list, we found that this way can't be
accepted because the function __of_translate_address() as a backend
of dev_get_addr(), shouldn't be used for translating a non-MMIO addresses.

Updating some device tree files with '#size-cells = 1' and by extending
the 'reg' property by address length - fixes the problem.

This applies on u-boot-dm/master:
c5a7533 net: Fix delay in net_retry test

[U-Boot] [PATCH 1/2] dts:exynos:update pinctrl size-cells and fix child regs

[Przemyslaw Marczak]

This change is required to avoid warnings about invalid
size-cells defined in device-tree pinctrl nodes for Exynos.

Tested on:
- Odroid U3
- Odroid XU3

[U-Boot] [PATCH 2/2] Revert "fdt: fix address cell count checking in fdt_translate_address()"

[Przemyslaw Marczak]

This reverts commit 71105f50fedddfa5b0535d102c3d5078671721ad.

The reverted commit was applied for a temporary to unbreak
few Exynos boards on the release.

After the discussion about the change, this commit should be avoided.
Fixed device-tree for Exynos, allows reverting it without any issues.
