Add suffix ULL to constant 256 in order to give the compiler complete information about the proper arithmetic to use. Notice that such constant is used in a context that expects an expression of type u64 (64 bits, unsigned) and the following expression is currently being evaluated using 32-bit arithmetic: 256 * fs * 2 * mclk_src_scaling[i].param Addresses-Coverity-ID: 1339616 ("Unintentional integer overflow") Signed-off-by:Gustavo A.

Machine drivers statically define a number of DAI links that currently cannot be changed or removed by topology. This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. 5) assign a new card name prefix to differentiate this topology to userspace. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies. Signed-off-by:

The generated clock (gclk) driver is able to set aclk as its parent and change its rate alone, if needed. This means that our driver no longer needs to configure aclk and we can let gclk select and configure its clock source. Signed-off-by:

Drop AVDD in favor of PVDD to match the names used in the datasheet and only claim PVDD on the es7154. The es7134 and es7144 don't have a separate supply for the digital I/O. Signed-off-by:

Now that the I2S channel names are fixed, and DMA data flow order is consistent (ch1 then ch2), we can simplify channel start order: start the upstream channel and then the downstream channel for both playback and capture cases. Signed-off-by:

The pointer() callback gets its value by reading the I2S BYTE_COUNT register. This is a 64-bit runnning transaction counter. If a transaction was aborted in the middle of a sample buffer, the counter will stop counting on a number divisible by the buffer size. Since we actually use it as a pointer into an aligned buffer, however, we do want to ensure that it always starts at a number divisible by the buffer size when starting a transaction, hence we reset it whenever starting a transaction. To accomplish this, it wasn't necessary to zero bytescount at the termination of each transaction, so remove this unnecessary code. Signed-off-by:

On capture, audio data is first copied from I2S to ACP memory, and then from ACP to SYSRAM. The I2S_TO_ACP_DMA interrupt fires on every sample transferred from I2S to ACP memory. That is it fires ~48000 times per second when capturing @ 48 kHz. Since we don't do anything on this interrupt anyway, disable it to save quite a few unnecessary interrupts. The real "work" (calling snd_pcm_period_elapsed()) is done when transfer from ACP to SYSRAM is complete. Signed-off-by:

On capture, audio data is first copied from I2S to ACP memory, and then to SYSRAM. For each step the channel number increases, so the names in the driver were wrong. Signed-off-by:

It is always correct to subtract out the starting bytescount value. Even in the case of 2^64 byte rollover (292 Million Years in the future @ 48000 Hz) the math still works out. Signed-off-by:

Commit 6b116dfb ("ASoC: AMD: make channel 1 dma as circular") made both channels circular, so this comment and logic no longer applies. Always stop ch2 (the channel closest to the output) before ch1. This ensures that the downstream circular DMA channel does not continue to play/capture repeated samples after the upstream circular DMA channel has already stopped. Signed-off-by:

We are currently using power saving mode for button detection. However, it will impact the headset recording performance. This patch will switch button detection to normal mode in capture and switch to power saving mode in the end of capture. Signed-off-by:
