After a quick look into the reference manuals:
Patch 5b72505 ("ARM: dts: imx53: add srtc node") is bad. The i.MX53 provides
an RTC more close to the i.MX6 instead (e.g. rtc-snvs.c). But unfortunately
it uses a different register layout than the i.MX6 does. So we can't use
this driver without i.MX53 specific adaptions.
But at least 5b72505 should be reverted.Agreed. Looked in the vendor kernel and this is the rtc driver for mx53: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-mxc_v2.c?h=imx_2.6.35_11.09.01 ,which is a different one from the dryice one: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/drivers/rtc/rtc-imxdi.c?h=imx_2.6.35_11.09.01 I will send a revert for 5b72505 ("ARM: dts: imx53: add srtc node"). Thanks
