[PATCH 4/4] ARM: dts: motorola-mapphone: fix LCD reset line polarity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The LCD driver (panel-dsi-cm), when performing reset, starts with line
set high, then drives it low, holds it there for a moment, and releases
it back to high.  This means that the reset line should be described
as "active low" in DTS. This will be important when the driver is
converted to gpiod API which respects the polarity declared in DTS.
