[PATCH/RFC 55/60] drm/omap: Pass pipe pointer to omap_crtc_init()

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

 



Replace the dss display device pointer by a pipe pointer that will allow
the omap_crtc_init() function to access both the display and the DSS
output. As a result we can remove the omapdss_device_get_dispc_channel()
function that is now unneeded.
