Subject: [PATCH v4 00/17] media: gmsl: Reliability improvements

Hello,
   series following:
v1: https://patchwork.linuxtv.org/project/linux-media/list/?series=4650
v2: https://patchwork.linuxtv.org/project/linux-media/list/?series=4861
v3: https://patchwork.linuxtv.org/project/linux-media/list/?series=4904

This series is a minor rework that builds on top of the comments received on v3.

I've re-order patches for better consumption:
[01/17] -> [05/17]: max9286 style fixes
[06/17] -> [07/17]: max9271 minor fixes
[08/17] -> [10/17]: rdamc21 fixes: these patches are relevant for RDACM21
 		    stability
[11/17] -> [15/17]: rdacm20 fixes
[16/17] -> [17/17]: GMSL initialization series rework, also relevant for syste,
                    stability

The only part where consensus still has to be reached is the last two patches.
Unfortunately, Sakari's suggestion of moving the remotes initialization to
s_stream() time did not work, and this version is the only one I've found that
gurantees a reliable initialization sequence. I've cc-ed Hans and Sakari to
continue the discussion.

Run quite some tests with Eagle and RDACM21: 1378 boot cycles with 100% boot
success (thanks Kieran for the board access).

Thanks
   j
