Subject: [PATCH 0/5] Suspend and resume fixes for omapdrm pdata removal

Hi all,

Recent omapdrm related changes to drop legacy platform data caused
a suspend and resume regression. I must have only tested suspend
and resume only with the changes preparing to drop the platform data,
but looks like I forgot to test suspend after dropping the platform
data.

There seem to be other longer term DSS regressions remaining too.
Looks like at least panel-simple currently does not probe. It fails
with "panel-simple display: Reject override mode: panel has a fixed
mode". I think the solution there is to drop the board specific
panel-timing related dts lines, but that still seems to be pending.
Anyways, no luck getting the LCD enabled on am437x-sk-evm with v5.6
or v5.7-rc kernels.

Regards,

Tony
