[PATCH 2/3] drm/tilcdc: Enable EOF interrupts for v1 LCDC

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

 



This got accidentally dropped in the fixed commit and is required for
the driver to properly work on the rev1 IP, such as found on the LCDK.

Fixes: 2b2080d7e9ae ("drm/tilcdc: Get rid of complex ping-pong mechanism")
