dmaengine: qcom: bam_dma: fix runtime PM underflow

2022-07-01T11:03:36+00:00

Commit dbad41e7bb5f ("dmaengine: qcom: bam_dma: check if the runtime pm enabled")
caused unbalanced pm_runtime_get/put() calls when the bam is
controlled remotely. This commit reverts it and just enables pm_runtime
in all cases, the clk_* functions already just nop when the clock is NULL.

Also clean up a bit by removing unnecessary bamclk null checks.

dmaengine: qcom: gpi: Add support for sc7280

2022-05-19T18:13:40+00:00

Add compatible and driver_data for GPI DMA engines found in Qualcomm
SC7280. The driver_data contains ee_offset of 0x10000.

dmaengine: hidma: In hidma_prep_dma_memset treat value as a single byte

2022-04-20T11:58:12+00:00

The value parameter is a single byte, so duplicate it to the 8 byte
range that is used as the pattern.

dmaengine: qcom: gpi: Add SM8350 support

2022-04-13T12:25:36+00:00

The Qualcomm SM8350 platform does, like the SM8450, provide a set of GPI
controllers with an ee-offset of 0x10000. Add this to the driver.

dmaengine: qcom: gpi: Add support for ee_offset

2022-04-13T12:24:39+00:00

Controller on newer SoCs like SM8450 have registers at at offset. Add
ee_offset to driver_data and add this compatible for the driver.

dmaengine: qcom: gpi: set chain and link flag for duplex

2022-04-13T12:24:39+00:00

Newer platforms seem to have strict requirement for TRE flags which
causes transaction to timeout. This was resolved to missing chain and
link flag for duplex spi transaction.

So add these two flags.

dmaengine: qcom_hidma: Remove useless DMA-32 fallback configuration

2022-03-11T09:53:23+00:00

As stated in [1], dma_set_mask() with a 64-bit mask never fails if
dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.

Simplify code and remove some dead code accordingly.

 "A bunch of new support and few updates to drivers:

  New support:
   - DMA_MEMCPY_SG support is bought back as we have a user in Xilinx
     driver
   - Support for TI J721S2 SoC in k3-udma driver
   - Support for Ingenic MDMA and BDMA in the JZ4760
   - Support for Renesas r8a779f0 dmac

  Updates:
   - We are finally getting rid of slave_id, so this brings in the
     changes across tree for that
   - updates for idxd driver
   - at_xdmac driver cleanup"

Pull sound updates from Takashi Iwai:
 "It's a relatively calm development cycle, but still lots of updates in
  the driver side like Intel SOF. Below are some highlights:

  ALSA / ASoC core:
   - A new kselftest for ALSA control API
   - PCM NO_REWINDS support
   - Potential race fixes around control removals
   - Unify x86 SG-buffer memory allocation code
   - Cleanups and race fixes for ASoC DPCM locking

  ASoC:
   - Refinements and cleanups around the delay() APIs
   - Wider use of dev_err_probe().
   - Continuing cleanups and improvements to the SOF code
   - Support for pin switches in simple-card derived cards
   - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
     systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
     S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
     TLV320ADC3xxx

  HD-audio / USB-audio:
   - Fix deadlock at HD-audio codec unbinding
   - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
   - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device

  Misc:
   - Fix virmidi drain behavior

  Note that the merge of CS35L41 codec support is still half-baked, and
  at least one ACPI change is missing. Although this won't hinder the
  kernel build itself, we're going to catch up before RC1"
