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.
