Subject: [PATCH v6 0/8] arm64: dts: renesas: Enable GMSL on Eagle and Condor
Date: Thu, 22 Jul 2021 11:12:31 +0200	[thread overview]
Message-ID: <20210722091239.26451-1-jacopo+renesas@jmondi.org> (raw)

Hello,
   here we go again with the attempt to try enable GMSL for Eagle and this time
also Condor board.

v5 highlighted an issue with the integration of RDACM20 which shown failures at
start streaming time due to conflicts with i2c writes performed by the embedded
microcontroller. A new patch
- media: i2c: rdacm20: Re-program chip address earlier
is aimed to fix the issue by reducing the collision window by re-programming the
chip address earlier. All capture session I've run seems stable now.

Compared to v5 integration for the Condor board is now included.

Condor has 2 GMSL channels, something the current version of the MAX9286 driver
does not support. However the DTS integration can be upstreamed but a single
channel can be used at a time.

Support for Condor required a reword of what was called eagle-gmsl.dtsi in v5
and is now called gmsl-cameras.dtsi to expand support for the secondary GMSL
channel.

Integration of the new "maxim,gpio-poc" property required for Eagle/Condor is
fully reviewed and can be eventually fast-tracked.

The series is based on:
https://patchwork.linuxtv.org/project/linux-media/list/?series=5847
and has been tested on Eagle V3H board, while only compile tested for Condor.

Thanks
   j
