This patch series adds support for configuring pbias register needed for
switching (ON/OFF, voltage scaling 3V, 1.8V) vmmc regulator suppling
OMAP mmc/sd1 i/o pads for device tree boot.
The control module registers are needed for mmc pbias i/o, speed mode
configuration of mmc1 and loopback clock configuration of mmc2.
With voltage switch support (pbias i/o) added for dt, enhance regulator
deferred probe handling by adding needs_vmmc and needs_vmmc_aux to indicate
whether regulator is applicable so that omap_hsmmc can handle regulator
deferred probe error properly.
Remove the assumption that vmmc_aux regulator to be present only if vmmc is
available. Platforms can have fixed-always-ON regulator for vmmc and/or vmmc_aux
in such cases vmmc regulator needed not be specified in board file.
Balaji T K (10):
ARM: OMAP2+: add needs_vmmc to hsmmc_info
mmc: omap_hsmmc: make vcc and vcc_aux independent
mmc: omap_hsmmc: use needs_vmmc
mmc: omap_hsmmc: update needs_vmmc for dt
mmc: omap_hsmmc: remove use_reg
mmc: omap_hsmmc: add support for pbias configuration in dt
mmc: omap_hsmmc: remove dt pbias workaround
ARM: dts: omap3: split omap3_pmx_core
ARM: dts: omap3: add pbias and mmc_init pinctrl states
ARM: dts: omap4: add pbias and mmc_init pinctrl states
