* Tomi Valkeinen <tomi.valkeinen@ti.com> [141204 23:42]: > The lcd0 node for am437x-sk-evm.dts contains bad LCD timings, and while > they seem to work with a quick test, doing for example blank/unblank > will give you a black display. > > This patch updates the timings to the 'typical' values from the LCD spec > sheet. > > Also, the compatible string is completely bogus, as > "osddisplays,osd057T0559-34ts" is _not_ a 480x272 panel. The panel on > the board is a newhaven one. Update the compatible string to reflect > this. Note that this hasn't caused any issues, as the "panel-dpi" > matches the driver. > > Cc: <stable@vger.kernel.org> # v3.17+ > Tested-by: Felipe Balbi <balbi@ti.com> > Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Applying into omap-for-v3.19/fixes thanks.
