The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void.

2023-02-28ASoC: mchp-pdmc: fix poc noises when startingMark Brown
Merge series from Claudiu Beznea <claudiu.beznea@microchip.com>: To start capture on Microchip PDMC the enable bits for each supported microphone need to be set. After this bit is set the PDMC starts to receive data from microphones and it considers this data as valid data. Thus if microphones are not ready the PDMC captures anyway data from its lines. This data is interpreted by the human ear as poc noises. To avoid this the following software workaround need to be applied when starting capture: 1/ enable PDMC channel 2/ wait 150ms 3/ execute 16 dummy reads from RHR 4/ clear interrupts 5/ enable interrupts 6/ enable DMA channel For this workaround to work step 6 need to be executed at the end. For step 6 was added patch 1/3 from this series. With this, component DAI driver sets its struct snd_soc_component_driver::start_dma_last = 1 and proper action is taken based on this flag when starting DAI trigger vs DMA.
2023-02-28ASoC: sam9g20ek: Disable capture unless building with microphone inputMark Brown
Without modification the AT91SAM9G20-EK has no capture support, none of the inputs of the CODEC are wired to anything to useful and there are no paths supporting loopback. Since the audio is clocked from the CODEC and the DAPM inputs are marked as unusable this means that capture will fail to transfer any data as the ADC path can't be powered up. Flag this in the device description so apps don't see unusable capture support, guarded with the existing optional define for mic input.

2023-02-28ASoC: mchp-pdmc: fix poc noise at capture startupClaudiu Beznea
Microchip PDMC IP doesn't filter microphone noises on startup. By default, it captures data received from digital microphones after the MCHP_PDMC_MR.EN bits are set. Thus when enable is set on PDMC side the digital microphones might not be ready yet and PDMC captures data from then in this time. This data captured is poc noise. To avoid this the software workaround is to the following: 1/ enable PDMC channel 2/ wait 150ms (on SAMA7G5-EK setup) 3/ execute 16 dummy reads from RHR 4/ clear interrupts 5/ enable interrupts 6/ enable DMA channel Fixes: 50291652af52 ("ASoC: atmel: mchp-pdmc: add PDMC driver") Signed-off-by: Claudiu Beznea <claudiu.beznea@microchip.com> Link: https://lore.kernel.org/r/20230228110145.3770525-4-claudiu.beznea@microchip.com Signed-off-by: Mark Brown <broonie@kernel.org>

2023-01-30ASoC: mchp-spdifrx: fix controls that works with completion mechanismClaudiu Beznea
Channel status get and channel subcode get controls relies on data returned by controls when certain IRQs are raised. To achieve that completions are used b/w controls and interrupt service routine. The concurrent accesses to these controls are protected by struct snd_card::controls_rwsem. Issues identified: - reinit_completion() may be called while waiting for completion which should be avoided - in case of multiple threads waiting, the complete() call in interrupt will signal only one waiting thread per interrupt which may lead to timeout for the others - in case of channel status get as the CSC interrupt is not refcounted ISR may disable interrupt for threads that were just enabled it. To solve these the access to controls were protected by a mutex. Along with this there is no need for spinlock to protect the software cache reads/updates b/w controls and ISR as the update is happening only when requested from control, and only one reader can reach the control.

2023-01-30ASoC: mchp-spdifrx: fix controls which rely on rsr registerClaudiu Beznea
The SPDIFRX block is clocked by 2 clocks: peripheral and generic clocks. Peripheral clock feeds user interface (registers) and generic clock feeds the receiver. To enable the receiver the generic clock needs to be enabled and also the ENABLE bit of MCHP_SPDIFRX_MR register need to be set. The signal control exported by mchp-spdifrx driver reports wrong status when the receiver is disabled. This can happen when requesting the signal and the capture was not previously started. To solve this the receiver needs to be enabled (by enabling generic clock and setting ENABLE bit of MR register) before reading the signal status. As with this fix there are 2 paths now that need to control the generic clock and ENABLE bit of SPDIFRX_MR register (one path though controls, one path though configuration) a mutex has been introduced. We can't rely on subsystem locking as the controls are protected by struct snd_card::controls_rwsem semaphore and configuration is protected by a different lock (embedded in snd_pcm_stream_lock_irq()). The introduction of mutex is also extended to other controls which rely on SPDIFRX_RSR.ULOCK bit as it has been discovered experimentally that having both clocks enabled but not the receiver (through ENABLE bit of SPDIFRX.MR) leads to inconsistent values of SPDIFRX_RSR.ULOCK. Thus on some controls we rely on software state (dev->trigger_enabled protected by mutex) to retrieve proper values.

2022-08-15ASoC: mchp-spdiftx: Fix clang -Wbitfield-constant-conversionNathan Chancellor
A recent change in clang strengthened its -Wbitfield-constant-conversion to warn when 1 is assigned to a 1-bit signed integer bitfield, as it can only be 0 or -1, not 1: sound/soc/atmel/mchp-spdiftx.c:505:20: error: implicit truncation from 'int' to bit-field changes value from 1 to -1 [-Werror,-Wbitfield-constant-conversion] dev->gclk_enabled = 1; ^ ~ 1 error generated. The actual value of the field is never checked, just that it is not zero, so there is not a real bug here. However, it is simple enough to silence the warning by making the bitfield unsigned, which matches the mchp-spdifrx driver.

Otherwise we can end up with an unbalanced reference counter for this interrupt.
