Subject: [PATCHv2 0/2] v4l: vsp1: Add HGT support
Date: Tue, 6 Sep 2016 16:38:54 +0200 [thread overview]
Message-ID: <20160906143856.27564-1-niklas.soderlund+renesas@ragnatech.se> (raw)
Hi,
This series add support for the VSP1 2-D histogram engine HGT.
It's based on top of Laurent Pinchart tree at
git://linuxtv.org/pinchartl/media.git hgo. And depends on Laurents patch
'[PATCH] v4l: vsp1: Move subdev operations from HGO to common histogram
code'.
It is tested on Koelsch using a modified vsp-tests suite package,
modifications can be found at https://git.ragnatech.se/vsp-tests hgt.
* Changes since v1
- Rebased on top of Laurents patch which made all subdev operations
common for HGO and HGT. This removed a lot of code that is now shared.
- Removed the Hue area configuration for the histogram pixel format.
These values are set by userspace so it already knows them.
- Updated pixel format documentation after input from Laurent.
- Better aligned the code to the existing VSP code base.
- Simplify check that hue areas are valid for the hardware.
- Fixed spelling.
