GMSL support now counts max9286 deserializer and rdacm20, rdacm21
camera modules.

Record the GMSL reliability investigation that took place in Q1 2021.

   - The MAX9286 has a version which is dependent upon the V4L2-Mux/Virtual Channel series.
   - Until that can be resolved, it is split so that we can aim to get the 'single' camera driver upstream.

+    GMSL reliability (Jacopo)
+    The currently mainlined (as of v5.12-rc1) version of GMSL support shows a
+    worrying 20% boot rate failure when tested with RDACM21 on Eagle V3M. An
+    investigation on the root causes of such bad performances has been
+    undergoing during Q4 2020 and Q1 2021, performing more than 500 boot tests
+    and resulting in 2 patch series sent for upstreaming integration.
+
+    v1 https://patchwork.linuxtv.org/project/linux-media/list/?series=4650
+    Shows a reliability improvement down to 13% failures when run on a 50 cycles
+    boot test.
+
+    v2 https://patchwork.linuxtv.org/project/linux-media/list/?series=4861
+    Fixes the reliability issue when tested with Eagle V3M and RDACM21 resulting
+    in a single failure when run on an 80 cycles boot test.
