[PATCH 10/10] drm/panel: raspberrypi-touchscreen: Remove MIPI-DSI driver

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

 



The driver was using a two-steps initialisation when probing with the
i2c probe first registering the MIPI-DSI device, and then when that
device was probed the driver would attach the device to its host. This
resulted in a fairly non-standard probe logic.

The previous commit changed that logic entirely though, resulting in a
completely empty MIPI-DSI device probe. Let's simplify the driver by
removing it entirely and just behave as a normal i2c driver.
