[PATCH v2] ARM: dts: tegra: correct Beaver pinmux

Lucas Stach dev at lynxeye.de
Fri Feb 26 11:18:30 PST 2016


Update pinmux to get rid of invalid uses of the rsvd1 function, which lead
to the mux settings on those pins to not be applied.

Also add correct drive settings, derived from the Tegra3 TRM, for SDIO1,
which makes some more SD-cards work.
