Few trivial omap MMC regression fixes for card voltages where the syscon areas for PBIAS regulator were missing "simple-bus" that prevents probing of the children in the mapped region. This probably was not noticed earlier as the bootloader has already configured the regulator for the card in the slot. * tag 'omap-for-v4.2/fixes-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: dra7: Fix broken pbias device creation ARM: dts: OMAP5: Fix broken pbias device creation ARM: dts: OMAP4: Fix broken pbias device creation ARM: dts: omap243x: Fix broken pbias device creation Signed-off-by: Olof Johansson <olof@lixom.net>
