Subject: [PATCH v13 01/21] dt-bindings: connector: analog: add sdtv standards property
Date: Thu, 12 Mar 2020 11:31:36 +0100 [thread overview]
Message-ID: <20200312103156.3178-2-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20200312103156.3178-1-m.felsch@pengutronix.de>
Some connectors no matter if in- or output supports only a limited
range of sdtv standards. It doesn't matter if the hardware behind that
connector supports more than the listed formats since the users are
restriced by a label e.g. to plug only a camera into this connector
which uses the PAL format.
This patch adds the capability to describe such limitation within the
firmware. There are no format restrictions if the property isn't
present, so it's completely backward compatible.

v12:
- split patch https://patchwork.linuxtv.org/patch/58491/
v10:
- fix typo s/TV_STD_*/SDTV_STD_*/
v8:
Hi Rob,
I dropped your r b tag becuase of the changes I made in this version.
Please can you have look on it again? Luckily this would be the last
time ;-)
- move definition to include/dt-bindings/display
- rename tvnorms.h to sdtv-standards.h
- TVORMS_* -> SDTV_STD_*
- add sync comments
- adapt commit message
- fix bindings documentation
v7:
I kept Robs r b tag because I only changed the example and extended
TVNORM_* macros.
- fix some style issues
- add TVNORM_NTSC, TVNORM_525_60 and TVNORM_625_50
v6:
- tvnorms.h: use tabs instead of spaces
- tvnorms.h: add TVNORM_PAL and TVNORM_SECAM
- tvnorms.h: drop rarely used TVNORM_ATSC_* norms
v2-v4:
- nothing since the patch was squashed from series [1] into this
series.
