Subject: [PATCH 0/2] arm64: dts: renesas: r8a7796{1,5}: Add CMT nodes
Date: Wed,  9 Dec 2020 21:07:36 +0100	[thread overview]
Message-ID: <20201209200738.811173-1-niklas.soderlund+renesas@ragnatech.se> (raw)

Hi,

Add CMT nodes to Renesas R-Car M3-W+ and D3 that for unknown reasons are 
missing these nodes. I only have access to the M3-W+ and I have tested 
this series on this (and H3, M3-W, M3-) by enabling all CMT nodes in DT 
and then using the kernel timer selftests located in
tools/testing/selftests/timers/

    - clocksource-switch.c
    - inconsistency-check.c
    - nanosleep.c

And if the fix for a deadlock race when switching clocksource [1] also 
is present the test pass on all SoCs mentioned above that I have access 
to. I have no reason to believe it would not also work on D3.

1. [PATCH 0/2] timekeeping: Fix change_clocksource() for PM and sh_cmt
