On Device Tree boot the VDDS_DSI regulator is not linked to
the DPI device so omapfb driver probing fails with:
[ 3.186035] OMAPFB: omapfb_probe
[ 3.190704] omapdss DPI error: can't get VDDS_DSI regulator

[ 3.216735] omapfb omapfb: failed to setup omapfb
As a workaround name the VPLL2 regulator from twl4030 as vdds_dsi
so getting the VDDS_DSI regulator will succeed on dpi_init_regulator().

Most of the boards are using the TI AM/DM37x processor, there is only a small
quantity of IGEP Processor Boards based on TI OMAP3530. So it's better use the

IGEP's DVI connector's DDC pins are connected to OMAP's third i2c bus.
When booting with Device Trees the requested bus number is set to -1
which means that the bus number should be dynamically assigned. So the

Since now only DT booting is supported for IGEP boards after commit

Enabling of Posted mode is seen to cause problems on dmtimer modules on AM33xx
(much like other OMAPs). Reference discussions on forums [1] [2]. Earlier
patch solving this on other OMAPs [3].
For OMAP SoCs with this errata, the fix has been to not enable Posted mode.
However, on some SoCs (atleast AM33xx) which carry this errata, Posted mode
is enabled on reset. So we not only need to ignore enabling of the POSTED bit
when the timer is requested, but also disable Posted mode if errata is present.
