It is also a hack but I solved on the IGEPv2 board by adding a regulator-name =
"vdds_dsi" to the VPLL2 regulator as suggested by Tony.
Look at commit 2f2befd8 ("ARM: dts: omap3-igep0020: name twl4030 VPLL2 regulator
as vdds_dsi")
Having the workaround in the Device Tree is better IMHO since this is a
per-board configuration. That can be later removed once the DSS DT bindings are
added to mainline.
Thanks a lot and best regards,
Javier
