The exact cause is > not fully understood, but it seems to be related to the probe order. SPI > communication to the panel driver (spi1.2) fails unless the touchscreen > (spi1.0) has been probed/initialized before. When the omap2-mcspi driver > was converted to a platform driver, it resulted in that the devices are > probed immediately after the board registers them in the order they are > listed in the board file. > > Fix the issue by moving the touchscreen before the panel in the SPI > device list. > > The patch fixes the following failure: > > [ 1.260955] acx565akm spi1.2: invalid display ID > [ 1.265899] panel-acx565akm display0: acx_panel_probe panel detect error > [ 1.273071] omapdss CORE error: driver probe failed: -19 Thanks for updating the description, applying into omap-for-v3.10/fixes.
