Subject: mmc: omap_hsmmc: allow the simple HS modes to use the default pinctrl
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bcc6bd84d48cfc5f7b777feb2e2a6e264b270252;p=project%2Fbcm63xx%2Fu-boot.git

mmc: omap_hsmmc: allow the simple HS modes to use the default pinctrl

The default configuration is usually working fine for the the HS modes.
Don't enforce the presence of a dedicated pinmux for the HS modes.
