Subject: [PATCH v3 0/2] DaVinci: VPIF: upgrade with v4l helpers
From: "Lad, Prabhakar" <prabhakar.csengg@...il.com>
Hi All,
This patch series upgrades the vpif capture & display
driver with the all the helpers provided by v4l, this makes
the driver much simpler and cleaner. This also includes few
checkpatch issues.
Sending them as single patch one for capture and another for
display, splitting them would have caused a huge number small
patches.
Changes for v2:
a> Added a copyright.
b> Dropped buf_init() callback from vb2_ops.
c> Fixed enabling & disabling of interrupts in case of HD formats.
Changes for v3:
a> Fixed review comments pointed by Hans.
v4l-compliance output is as follows:--
