Subject: ARM: mach-imx: support for DryIce RTC in i.MX53
X-Git-Tag: next-20121029~1^2~41
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=1cab4eeba9cb0a2b5536b046c1380c20c2f45e22;p=karo-tx-linux.git

ARM: mach-imx: support for DryIce RTC in i.MX53

Enable support for i.MX53 in addition to i.MX25 by providing a dummy clock
on i.MX53 since this one doesn't have a separate clock for internal RTC
but the driver requests one.
