Subject: [PATCH v18 0/4] Add NVIDIA Tegra GPC-DMA driver
Date: Tue, 1 Feb 2022 20:56:35 +0530 [thread overview]
Message-ID: <1643729199-19161-1-git-send-email-akhilrajeev@nvidia.com> (raw)
Add support for NVIDIA Tegra general purpose DMA driver for
Tegra186 and Tegra194 platform.
v17 -> v18:
* Add get_residual() to get residual in tx_status()
* Added label for device tree node so that the phandle
can be used in client devices using the dma.
