From: Chen-Yu Tsai <w...@csie.org>
The rockchip_dw_mmc driver supports the MMC controller found in Rockchip
SoCs. This controller is used for the SD card on all SoCs and eMMC on
older SoCs. Almost all defconfigs for Rockchip platforms have this
enabled.
Enable it by default for all supported Rockchip SoCs. Disable it
explicitly in defconfigs that previously didn't have it enabled. Of
these, only the Cool Pi GenBook w/ CM5 doesn't actually use the
controller. The other two, the Geekbox and the RV1108 EVB, both have
MMC enabled in their device trees. With this patch, they will gain
support for MMC automatically.
Also limit the driver to Rockchip platforms only, like what is done for
the other dw_mmc platform glue drivers.
