[PATCH 00/24] R-Car VSP1: Histogram, look-up table and flip support

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

 



Hello,

Here's my current set of pending VSP1 patches, based on top of the
"[PATCH v2 00/13] R-Car VSP improvements for v4.7 - Round 2" series. For
convenience I've pushed the patches and their dependencies to

	git://linuxtv.org/pinchartl/media.git vsp1/flip

The series contains new features as well as several fixes. In particular the
driver now supports histogram generation through the HGO (01/24 to 04/24),
doesn't generate warnings to the kernel log due to uninitialized functions
(05/24 to 10/24), supports the LUT and CLU (12/24 to 19/24), supports
horizontal and vertical flipping (20/24 to 22/24) and doesn't attempt to
access freed buffers anymore (24/24).

I plan to send a pull request for v4.8 as soon as the previous pull request
gets merged.
