sunxi: driver refresh for 3.13
- update gmac / mmc / usb / ahci drivers to follow mainline dev trees - add driver for spi - update clock support - update a31 support - move to new DT compats where appropriate - re-order patchqueue where needed - verified working a20 smp - move most DTSes off files/ - update defconfig Signed-off-by: Zoltan HERPAI <wigyori@uid0.hu> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@39782 3c298f89-4303-0410-b956-a3cf2f4a3e73

+Subject: [PATCH] sunxi-mmc: Don't set mmc clk in low power mode
+
+The android driver uses an io-flag to descern whether a controller is
+hooked up to a sdcard slot, or to an onboard sdio dev. And for sdcard slots
+it sets the clock in a low-power mode.
+
+This is causing transmission errors when talking to the sdio-wifi on the
+cubietruck, and this may be the cause of problems with some type sdcards
+too. This patch fixes things by simply never setting the clk in low power
+mode.
+
