Subject: [PATCH v3 0/3] Add compatible for Tegra234 GPCDMA
Date: Mon, 11 Jul 2022 21:15:33 +0530 [thread overview]
Message-ID: <20220711154536.41736-1-akhilrajeev@nvidia.com> (raw)
Tegra234 supports recovery of a channel hung in pause flush mode.
This could happen when the client bus gets corrupted or if the end
device ceases to send/receive data.
Add a separate compatible for Tegra234 so that this scenario can be
handled in the driver.
v2->v3:
* Updated binding docs and device tree compatible
v1->v2:
* split device tree change to a different patch.
* Update commit message
Akhil R (3):
dt-bindings: dmaengine: Add compatible for Tegra234
dmaengine: tegra: Add terminate() for Tegra234
arm64: tegra: Update compatible for Tegra234 GPCDMA
