[PATCH RFC 12/31] mmc: sdhci: convert reset into a library function

Russell King rmk+kernel at arm.linux.org.uk
Wed Feb 19 02:10:04 EST 2014


Rather than having platform_reset_enter/platform_reset_exit methods,
turn the core of the reset handling into a library function which
platforms can call at the appropriate moment in their (new) reset
method.
