ARM: dts: Use drive strength 3 for SD pins for exynos4
Browse files Browse the repository at this point in the history 
This patch modifies pin control groups of SD pins on EXYNOS4210
and EXYNOS4X12 to use drive strength 3 as a default value which
corresponds to S5P_GPIO_DRVSTR_LV4 in legacy non-DT code.

This is needed at least on Origen board for sdhci2 to work and
if any other drive strength is required on each board, we can
overide it.
