Subject: drivers/rtc/rtc-at91rm9200.c: make IO endian agnostic
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6da7bb1e9cef9ab956e4223125090e4465f51fb2;p=linux-beck.git

drivers/rtc/rtc-at91rm9200.c: make IO endian agnostic

Change the __raw IO calls to readl/write_relaxed which makes the driver
endian agnostic to run properly on big endian systems.
