Subject: [PATCH v9 0/5] spi: dw: DW SPI DMA Driver updates
Date: Thu, 27 Apr 2023 12:33:09 +0000 [thread overview]
Message-ID: <20230427123314.1997152-1-joychakr@google.com> (raw)
This Patch series adds support for 32 bits per word trasfers using DMA
and some defensive checks around dma controller capabilities.
---
V1 Changes : Add support for AxSize=4 bytes to support 32bits/word.
---
V1->V2 Changes : Add dma capability check to make sure address widths
are supported.
---
V2->V3 Changes : Split changes , add DMA direction check and other
cosmetic chnages.
---
V3->V4 Changes : Fix Sparce Warning

---
V4->V5 Changes : Preserve reverse xmas Tree order, move direction
check before initalisation of further capabilities, remove zero
initialisations, remove error OR'ing.
---
V5->V6 Changes :
-Remove case of n_bytes=3 using 4_bytes buswidth
-Avoid forward decaration
-Break capability check patch into 2
-round n_bytes to power of 2 ( Bug Fix)
-Add more explanation in commit text.
---
V6->V7 Changes : Remove extra spaces, refer to functions in commit as
func()
---
V7->V8 Changes : Minor commment updates in patch 4/5
---
V8->V9 Changes : Minor formatting changes in patch 5/5
---
Joy Chakraborty (5):
