[PATCH v6 00/21] ASoC: fsl_micfil: Driver updates
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 twice. Drop second read.

clk_div = mclk_rate / (get_pdm_clk(micfil, rate) * 2);
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.

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 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 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.

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.

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
