I added one more ack from Shengjiu Wang, but other than that it's just a
resend with +Cc: Mark Brown
Sascha
Changes since v5:
- Add one more ack from Shengjiu Wang
Changes since v4:
- collect more acks
- whitespace cleanup in 16/21
Changes since v3:
- Add commit log to "ASoC: fsl_micfil: drop unused variables"
- Fix include name in "ASoC: fsl_micfil: add multi fifo support"
- Drop unnecessary temporary adding of struct fsl_micfil::osr
- Leave default quality setting at 'medium'
- Drop debugging message printed at error level
- collect acks from Shengjiu Wang and Vinod Koul
Changes since v2:
- Add forgotten commit log to dmaengine patches
- Add patch to move include/linux/platform_data/dma-imx.h to include/linux/dma/imx-dma.h
- Use prefix dmaengine: for dma patches
Changes since v1:
- Drop unused variable sw_done_sel
- Evaluate sdmac->direction directly instead of storing value in n_fifos
- add missing include linux/bitfield.h

In get_pdm_clk() REG_MICFIL_CTRL2 is read, but the result is never used.

All that the .set_sysclk hook in the micfil driver does is to pass
the sysclk frequency to fsl_micfil_set_mclk_rate(). This function
expects the sample rate as argument though, not any kind of sysclk
frequency. The resulting rate setting of the clock is overwritten
in hw_params anyway, so drop this altogether.

No need to have defines for the mask of single bits. Also shift is
unused. Drop all these unnecessary defines.

* [PATCH v6 04/21] ASoC: fsl_micfil: do not define SHIFT/MASK for single bits

No need to have defines for the mask of single bits. Also shift is
unused. Drop all these unnecessary defines.

* [PATCH v6 05/21] ASoC: fsl_micfil: use GENMASK to define register bit fields

Use GENMASK along with FIELD_PREP and FIELD_GET to access bitfields in
registers to straighten register access and to drop a lot of defines.

* [PATCH v6 05/21] ASoC: fsl_micfil: use GENMASK to define register bit fields

Use GENMASK along with FIELD_PREP and FIELD_GET to access bitfields in
registers to straighten register access and to drop a lot of defines.

Instead regmap_update_bits() use the simpler variants
regmap_[set|clear]_bits() where appropriate.

Failed register accesses are really not expected in memory mapped
registers. When it fails then the register access itself is likely not
the reason, so no need to have extra error messages for each regmap
access. Just drop the error messages. This also fixes some places where
a return value is concatenated using 'ret |=' and then returned as
error value.

The i.MX DMA drivers are device tree only, nothing in
include/linux/platform_data/dma-imx.h has platform_data in it, so move
the file to include/linux/dma/imx-dma.h.

* [PATCH v6 10/21] dmaengine: imx-sdma: error out on unsupported transfer types

The i.MX SDMA driver currently silently ignores unsupported transfer
types. These transfer types are specified in the dma channel description
in the device tree, so they should really be checked.
Issue a message and error out when we hit unsupported transfer types.

* [PATCH v6 10/21] dmaengine: imx-sdma: error out on unsupported transfer types

The i.MX SDMA driver currently silently ignores unsupported transfer
types. These transfer types are specified in the dma channel description
in the device tree, so they should really be checked.
Issue a message and error out when we hit unsupported transfer types.

The i.MX SDMA engine can read from / write to multiple successive
hardware FIFO registers, referred to as "Multi FIFO support". This is
needed for the micfil driver and certain configurations of the SAI
driver. This patch adds support for this feature.
The number of FIFOs to read from / write to must be communicated from
the client driver to the SDMA engine. For this the struct
dma_slave_config::peripheral_config field is used.

The micfil hardware provides the microphone data on multiple successive
FIFO registers, one register per stereo pair. Also to work properly the
SDMA_DONE0_CONFIG_DONE_SEL bit in the SDMA engines SDMA_DONE0_CONFIG
register must be set. This patch provides the necessary information to
the SDMA engine driver.

The micfil hardware provides the microphone data on multiple successive
FIFO registers, one register per stereo pair. Also to work properly the
SDMA_DONE0_CONFIG_DONE_SEL bit in the SDMA engines SDMA_DONE0_CONFIG
register must be set. This patch provides the necessary information to
the SDMA engine driver.

The OSR (OverSampling Rate) setting is set once to the default value
and never changed throughout the driver. Nevertheless the value is
read back from the register for further calculations. Just use the
default value because we know what we have written.

get_pdm_clk() calculates the PDM clock based on the quality setting,
but really the PDM clock is independent of the quality, it's always
rate * 4 * micfil->osr. Just drop the function and do the calculation
in the caller.

The reference manual has this for calculating the micfil internal clock
divider:
MICFIL Clock rate
clkdiv = -----------------
8 * OSR * outrate
(with OSR == Oversampling Rate, outrate == output sample rate)
The driver first sets the MICFIL Clock rate to (outrate * 1024) and then
calculates back the clkdiv value from the above calculation.
Simplify this by using a fixed clkdiv value of 8 and set the MICFIL
Clock rate to (outrate * clkdiv * OSR * 8).
While at it drop disabling the clock before setting its rate. The MICFIL
module is disabled when the rate is changed and it is also resetted
before it is started again, so I doubt it's necessary to disable the
clock.

* [PATCH v6 16/21] ASoC: fsl_micfil: rework quality setting

For the quality setting the quality setting register values are directly
exposed to the kcontrol and thus to userspace. This is unfortunate
because the register settings contains invalid bit combinations marked
as "N/A". For userspace it doesn't make much sense to be able to set
these just to see that the driver responds with "Please make sure you
select a valid quality." in the kernel log.
Work around this by adding get/set functions for the quality setting.

The "fsl,shared-interrupt" property is undocumented and unnecessary.
Just pass IRQF_SHARED unconditionally.

caller, do so.

The micfil driver prints out the IRQ numbers for each interrupt at error
level. This information is useful for debugging at best, remove it.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
