If anyone has any objections, please let me know. ------------------ From: Artur Weber [ Upstream commit eab4f56d3e75dad697acf8dc2c8be3c341d6c63e ] After more investigation, I've found that it's not the panel driver config that needs to be modified to invert the data polarity, but the FIMD config. Add the missing invert-vclk option that is required to get the display to work correctly.
