Subject: [PATCH 0/2] spi: spi-geni-qcom: Add new interfaces and utilise them to do map/unmap in framework for SE DMA
Date:   Fri, 12 May 2023 22:37:43 +0530
Message-Id: <1683911265-3395-1-git-send-email-quic_vnivarth@quicinc.com>
Precedence: bulk

A "known issue" during implementation of SE DMA for spi geni driver was
that it does DMA map/unmap internally instead of in spi framework.
Current patches remove this hiccup and also clean up code a bit.

Testing revealed no regressions and results with 1000 iterations of
reading from EC showed no loss of performance.
Results
=======
Before - Iteration 999, min=5.10, max=5.17, avg=5.14, ints=25129
After  - Iteration 999, min=5.10, max=5.20, avg=5.15, ints=25153

  soc: qcom: geni-se: Add interfaces geni_se_tx_init_dma() and
    geni_se_rx_init_dma()
  spi: spi-geni-qcom: Do not do DMA map/unmap inside driver, use
    framework instead
