Earlier the PBIAS regulator was optional, not so with recent omap_hsmmc changes. To make things easier for people with custom .config files, let's add minimal documentation for it as suggested by Russell King <rmk+kernel@arm.linux.org.uk>. Signed-off-by: Tony Lindgren <tony@atomide.com>
This file contains documentation for running mainline kernel on omaps. KERNEL NEW DEPENDENCIES v4.3+ Update is needed for custom .config files to make sure CONFIG_REGULATOR_PBIAS is enabled for MMC1 to work properly.
