Subject: [PATCH v5 0/3] Add RZ/G2L DMAC support
Date: Thu, 29 Jul 2021 09:25:17 +0100	[thread overview]
Message-ID: <20210729082520.26186-1-biju.das.jz@bp.renesas.com> (raw)

This patch series aims to add DMAC support on RZ/G2L SoC's.

It is based on the work done by Chris Brandt for RZ/A DMA driver.

v4->v5:
 * Passing legacy slave channel configuration parameters using dmaengine_slave_config is prohibited.
   So started passing this parameters in DT instead, by encoding MID/RID values with channel parameters
   in the #dma-cells.
 * Removed Rb tag's of Geert and Rob since there is a modification in binding patch
 * Added 128 byte slave bus width support
 * Removed SoC dtsi and Defconfig patch from this series. Will send as separate patch.

v3->v4:
 * Added Rob's Rb tag for binding patch.
 * Incorporated Vinod and Geert's review comments.
v2->v3:
  * Described clocks and resets in binding file as per Rob's feedback.

v1->v2
 * Started using virtual DMAC
 * Added Geert's Rb tag for binding patch.
