* ASoC: atmel-classd: Remove endianness flag on class d componentCharles Keepax2022-06-091-1/+0
| | | | | | | | | | | | | | | | | | | | | [ Upstream commit 0104d52a6a69b06b0e8167f7c1247e8c76aca070 ] The endianness flag should have been removed when the driver was ported across from having both a CODEC and CPU side component, to just having a CPU component and using the dummy for the CODEC. The endianness flag is used to indicate that the device is completely ambivalent to the endianness of the data, typically due to the endianness being lost over the hardware link (ie. the link defines bit ordering). It's usage didn't have any effect when the driver had both a CPU and CODEC component, since the union of those equals the CPU side settings, but now causes the driver to falsely report it supports big endian. Correct this by removing the flag.

* ASoC: atmel: Remove system clock tree configuration for at91sam9g20ekMark Brown2022-04-041-61/+0
| | | | | | | | | | | | | | | | | | | | | The MCLK of the WM8731 on the AT91SAM9G20-EK board is connected to the PCK0 output of the SoC, intended in the reference software to be supplied using PLLB and programmed to 12MHz. As originally written for use with a board file the audio driver was responsible for configuring the entire tree but in the conversion to the common clock framework the registration of the named pck0 and pllb clocks was removed so the driver has failed to instantiate ever since. Since the WM8731 driver has had support for managing a MCLK provided via the common clock framework for some time we can simply drop all the clock management code from the machine driver other than configuration of the sysclk rate, the CODEC driver still respects that configuration from the machine driver.

| | | | | | | | | | | | | | | | | | | | | | | | In function mchp_pdmc_af_put(), Intel's kernel test robot reports the following warning: sound/soc/atmel/mchp-pdmc.c:186:34: warning: address of array \ 'uvalue->value.integer.value' will always evaluate to 'true' \ [-Wpointer-bool-conversion] This is because we are using `uvalue->value.integer.value` which its type is `long value[128];` for conditional expression and that array will always decay to a non-NULL pointer.

* Add driver for SAMA7G5's PDMCMark Brown2022-03-083-0/+1102
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge series from Codrin Ciubotariu <codrin.ciubotariu@microchip.com>: This patch series adds support for Pulse Density Microphone Controller (PDMC), present on Microchip's SAMA7G5. The PDMC interfaces up to 4 digital microphones having Pulse Density Modulated (PDM) outputs. It generates a single clock line and samples 1 or 2 data lines. The signal path includes an audio grade programmable decimation filter and outputs 24-bit audio words. The source of each channel can be independently defined as PDMC_DS0 or PDMC_DS1, sampled at the rising or falling edge of PDMC_CLK. The patch series starts with a fix on the ASoC DMA engine support. Then continues with the bindings and the driver of PDMC. It is followed by the DT nodes for SAMA7G5 and SAMA7G5-EK. In the end, the drivers for PDMC and PDM microphones are enabled in sama7_defconfig.

* ASoC: mchp-i2s-mcc: Add support to select TDM pinsCodrin Ciubotariu2021-03-101-4/+48
| | | | | | | | | | | | | SAMA7G5's I2S-MCC has 4 pairs of DIN/DOUT pins. Since TDM only uses a single pair of pins for synchronous capture and playback, the controller needs to be told which of the pair is connected. This can be mentioned using the "microchip,tdm-data-pair" property from DT. The property is optional, useful only if TDM is used. If it's missing, DIN/DOUT 0 pins will be used by default.

* ASoC: mchp-i2s-mcc: Add multi-channel support for I2S and LEFT_J formatsCodrin Ciubotariu2021-03-101-0/+38
| | | | | | | | | | | The latest I2S-MCC available in SAMA7G5 supports multi-channel for I2S and Left-Justified formats. For this, the new version uses 8 (4 * 2) input and output pins, with each pin being responsible for 2 channels. This sums up to a total of 8 channels for synchronous capture and playback.

* ASoC: atmel-pdc: Use managed DMA buffer allocationLars-Peter Clausen2021-01-131-74/+4
| | | | | | | | | | | | | | | | Instead of manually managing its DMA buffers using dma_{alloc,free}_coherent() lets the sound core take care of this using managed buffers. On one hand this reduces the amount of boiler plate code, but the main motivation for the change is to use the shared code where possible. This makes it easier to argue about correctness and that the code does not contain subtle bugs like data leakage or similar.
