[PATCH v5 0/6] media: Introduce Allwinner H3 deinterlace driver

[Jernej Skrabec]

Starting with H3, Allwinner began to include standalone deinterlace
core in multimedia oriented SoCs. This patch series introduces support
for it. Note that new SoCs, like H6, have radically different (updated)
deinterlace core, which will need a new driver.
