That node looks fine, but I wonder why we need to mark a bunch of
regulators as always-on? shouldn't the references to vdd-supply and
power-supply from this node be enough? If not, perhaps the tree
structure of the regulators isn't correct, or the DSI or panel bindings
don't allow enough regulators to be referenced?
regulator-always-on is indeed not needed for vdd_lcd. I actually had a
patch in my tree removing this line that I forgot to squash. Will post a
v2 for this patch that fixes this, thanks.
vdd-2v8-display needs to remain always-on however. Here we may hit a
limitation of the simple-panel driver, where only one power supply can
be provided.
