[PATCH 07/16] drm/exynos: get encoder from bridge whenever possible

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

 



The bridge will not necessarily use the encoder of struct exynos_dsi,
but might use another encoder from another drm driver. Therefore, the
driver has to use the encoder from the bridge instead of the one from
exynos_dsi.
