[PATCH] ARM: dts: am335x-bone-common: Fix mmc0 Write Protect

[Robert Nelson]

Mainline Commit b74c2b21e1551018af53ee6c1efc051dfce2d788 added the pinmux
settings for mmc1, however this pin (0x9a0) is routed to P9_42 on the cape
header. Thus any BeagleBone cape that utilizes P9_42 triggers mmc0's Write
Protect.

Thanks applying into omap-for-v4.18/fixes. I'll also add a Fixes tag for
it.

The evm sk sdwp needs to be removed as well. I guess I'll post a
separate patch as this is already applied.

Thanks,
