[PATCH 0/4] i.MX27: visstrim_m10: Add several peripherals.

[Javier Martin]

I've splitted video related patch into three to attend Uwe's requirements
and have added RTC support too.

[PATCH v2 1/4] i.MX27: visstrim_m10: Sort IMX_HAVE_PLATFORM_MXC_MMC properly.
[PATCH v2 2/4] i.MX27: visstrim_m10: Register I2C devices after I2C busses have been added.
[PATCH v2 3/4] i.MX27: visstrim_m10: Add m41t00 RTC support.
[PATCH v2 4/4] i.MX27: visstrim_m10: Add video support.

[PATCH v2 1/4] i.MX27: visstrim_m10: Sort IMX_HAVE_PLATFORM_MXC_MMC properly.
