2022-02-08ASoC: xilinx: xlnx_formatter_pcm: Make buffer bytes multiple of period bytesRobert Hancock
commit e958b5884725dac86d36c1e7afe5a55f31feb0b2 upstream. This patch is based on one in the Xilinx kernel tree, "ASoc: xlnx: Make buffer bytes multiple of period bytes" by Devarsh Thakkar. The same issue exists in the mainline version of the driver. The original patch description is as follows: "The Xilinx Audio Formatter IP has a constraint on period bytes to be multiple of 64. This leads to driver changing the period size to suitable frames such that period bytes are multiple of 64. Now since period bytes and period size are updated but not the buffer bytes, this may make the buffer bytes unaligned and not multiple of period bytes. When this happens we hear popping noise as while DMA is being done the buffer bytes are not enough to complete DMA access for last period of frame within the application buffer boundary. To avoid this, align buffer bytes too as multiple of 64, and set another constraint to always enforce number of periods as integer. Now since, there is already a rule in alsa core to enforce Buffer size = Number of Periods * Period Size this automatically aligns buffer bytes as multiple of period bytes."

2021-08-18ASoC: xilinx: Fix reference to PCM buffer addressTakashi Iwai
commit 42bc62c9f1d3d4880bdc27acb5ab4784209bb0b0 upstream. PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The driver needs to refer to substream->runtime->dma_addr instead for the buffer address.

2019-11-25Revert "ASoC: Remove dev_err() usage after platform_get_irq()"Dong Aisheng

2019-08-02ASoC: Remove dev_err() usage after platform_get_irq()Stephen Boyd
We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

2019-01-03ASoC: xlnx: fix error handling in xlnx_formatter_pcm_probeGustavo A. R. Silva
Currently, if platform_get_irq_byname() fails, the returned error turns into a huge value, once it is being store into a variable of type unsigned int, hence never actually reporting any error and causing unexpected behavior when using the values stored in aud_drv_data->s2mm_irq and aud_drv_data->mm2s_irq. Fix this by changing the type of variables s2mm_irq and mm2s_irq in structure xlnx_pcm_drv_data from unsigned int to int.
