Subject: [PATCH 0/2] Add compatible for Tegra234 GPCDMA
Date: Thu, 7 Jul 2022 15:57:23 +0530 [thread overview]
Message-ID: <20220707102725.41383-1-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.
