Subject: [PATCH 0/4] slimbus: patches (set 1) for 5.15
Date: Fri,  6 Aug 2021 10:16:35 +0100	[thread overview]
Message-ID: <20210806091639.532-1-srinivas.kandagatla@linaro.org> (raw)

Hi Greg,

Recently runtime pm testing on slimbus reveled that its
totally broken on SlimBus ngd drivers.

Below are the fixes to get it back working.

- One of the reason begin incorrect device pointer used for
runtime pm and in some places

- Second one was to do with unable to validate transaction id
 which resulted in negative runtime pm count.

- Other fix was to do with resetting dma addresses once ngd
controller is power-cycled.

With all these fixed runtime pm is now fully functional on NGD
controllers.

Currently I marked them all with Cc: <stable@vger.kernel.org>
as these all patches are required to fix runtime pm on SlimBus
NGD controller.

Can you please queue them up for 5.15.

thanks for you help,
srini
