Andy Shevchenko 703aae3d09 mmc: add a file to debugfs for changing host clock at runtime ... For debugging power management features it is convenient to have the possibility of changing the MMC host controller clock at runtime. This patch adds a 'clock' file for this under the MMC host root of debugfs. Usage is as follows: # cat /sys/kernel/debug/mmc0/clock 52000000 # echo "1000000000" > /sys/kernel/debug/mmc0/clock # cat /sys/kernel/debug/mmc0/clock 52000000 # echo "48000000" > /sys/kernel/debug/mmc0/clock # cat /sys/kernel/debug/mmc0/clock 48000000 The middle example shows limits being applied by the host driver.
