Subject: mmc: exynos_dw_mmc: Use .of_to_plat for device tree parsing
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-logo.png?a=commitdiff_plain;h=658a1b873ad4997feed7572cd3cca7fee01ac9f2;p=u-boot.git

mmc: exynos_dw_mmc: Use .of_to_plat for device tree parsing

exynos_dwmci_get_config() is called from the probe function and used to
read data from device tree. Make use of .of_to_plat driver callback
instead, and convert exynos_dwmci_get_config() to match its signature.

No functional change.
