2023-05-11ASoC: jz4740-i2s: Add support for X1000 SoCAidan MacDonald
The X1000's AIC is similar to the AIC found on other Ingenic SoCs. It has symmetric playback/capture rates like the JZ4740, but more flexible clocking when outputting the system or bit clocks.

2023-05-11ASoC: jz4740-i2s: Make I2S divider calculations more robustAidan MacDonald
When the CPU supplies bit/frame clocks, the system clock (clk_i2s) is divided to produce the bit clock. This is a simple 1/N divider with a fairly limited range, so for a given system clock frequency only a few sample rates can be produced. Usually a wider range of sample rates is supported by varying the system clock frequency. The old calculation method was not very robust and could easily produce the wrong clock rate, especially with non-standard rates. For example, if the system clock is 1.99x the target bit clock rate, the divider would be calculated as 1 instead of the more accurate 2. Instead, use a more accurate method that considers two adjacent divider settings and selects the one that produces the least error versus the requested rate. If the error is 5% or higher then the rate setting is rejected to prevent garbled audio. Skip divider calculation when the codec is supplying both the bit and frame clock; in that case, the divider outputs are unused and we don't want to constrain the sample rate.

2022-10-31ASoC: jz4740-i2s: Remove .set_sysclk()Aidan MacDonald
.set_sysclk() is effectively unused here. No machine drivers use jz4740-i2s; and JZ4740_I2S_CLKSRC_EXT is the only selectable clock source with simple-card, but that is also the default source and has a fixed frequency, so configuring it would be redundant. simple-card ignores -ENOTSUPP error codes when setting the sysclock, so any device trees that do set the sysclock for some reason should still work. It's still possible to configure the clock parent manually in the device tree and control frequency using other simple-card options, so at the end of the day there's no real loss in functionality.

2022-10-26ASoC: jz4740-i2s: Handle independent FIFO flush bitsAidan MacDonald
On the JZ4740, there is a single bit that flushes (empties) both the transmit and receive FIFO. Later SoCs have independent flush bits for each FIFO. Independent FIFOs can be flushed before the snd_soc_dai_active() check because it won't disturb other active streams. This ensures that the FIFO we're about to use is always flushed before starting up. With shared FIFOs we can't do that because if another substream is active, flushing its FIFO would cause underrun errors. This also fixes a bug: since we were only setting the JZ4740's flush bit, which corresponds to the TX FIFO flush bit on other SoCs, other SoCs were not having their RX FIFO flushed at all.

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-04-23ASoC: jz4740: Improve build test coverageLars-Peter Clausen
Allow the jz4740 audio drivers to be build when CONFIG_COMPILE_TEST is selected. This should improve the build test coverage. There is one small piece of platform dependent code in the jz4740-i2s driver. It uses the DMA request type constants which are defined in a platform specific header. We can solve this by moving them from the platform specific header to the I2S driver.

2013-12-03ASoC: jz4740: Use the generic dmaengine PCM driverLars-Peter Clausen
Now that there is a dmaengine driver for the jz4740 DMA core we can use the generic dmaengine PCM driver. This allows us to remove the custom jz4740-pcm code completely. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@linaro.org>
