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
