2017-04-21ASoC: qcom: move clock names into LPASS variant structLinus Walleij1-15/+7
The clock names for the two supported codecs are either "mi2s-*" name variants generated by code. This naming scheme does not work for platforms like MSM8660 which has I2S channels named CODEC_I2S_SPKR (rather than just "MI2S tertiary" and other repetitive names) and consequently have clocks named "codec-i2s-spkr-osr-clk" and similar. Skip the runtime generation of clock names and replace it with name lookup tables encoded into the variant data.

2017-01-31ASoC: qcom: Drop __func__ usage from log printsBjorn Andersson1-50/+36
The combination of dev_err() and __func__ make most of these log prints over 100 chars long. Remove the usage of __func__ to clean the kernel log and as the usage is not necessary to identify the individual log prints.

2017-01-31ASoC: qcom: lpass-cpu: Remove unnecessary clock checksBjorn Andersson1-17/+10
Clean up the clock calling code by removing numerous IS_ERR() checks by just assigning the clock NULL; as this turn all used functions in the clk API to nops. Also include the word "optional" in the error message when failing to acquire the optional osr clocks.

2016-10-31ASoC: lpass-cpu: add module licence and descriptionSrinivas Kandagatla1-0/+3
This patch adds module licence to lpass-cpu driver, without this patch lpass-cpu module would taint with below error: snd_soc_lpass_cpu: module license 'unspecified' taints kernel.

2016-02-20ASoC: qcom: add mic supportSrinivas Kandagatla1-30/+83
This patch adds mic support to the lpass driver, most of the driver is reused as it is, only the register level access is changed depending on te direction of the stream.

2016-02-12ASoC: qcom: Don't specify LE device endiannessStephen Boyd1-1/+0
This reverts commit 18560a4e3 (ASoC: qcom: Specify LE device endianness). The commit that caused us to specify LE device endianness here, 29bb45f25ff3 (regmap-mmio: Use native endianness for read/write, 2015-10-29), has been reverted in mainline so now when we specify LE it actively breaks big endian kernels because the byte swapping in regmap-mmio is incorrect. Let's revert this change because it will 1) fix the big endian kernels and 2) be redundant to specify LE because that will become the default soon.

2015-11-21ASoC: qcom: Specify LE device endiannessStephen Boyd1-0/+1
This is a little endian device, but so far we've been relying on the regmap mmio bus handling this for us without explicitly stating that fact. After commit 4a98da2164cf (regmap-mmio: Use native endianness for read/write, 2015-10-29), the regmap mmio bus will read/write with the __raw_*() IO accessors, instead of using the readl/writel() APIs that do proper byte swapping for little endian devices. So if we're running on a big endian processor and haven't specified the endianness explicitly in the regmap config or in DT, we're going to switch from doing little endian byte swapping to big endian accesses without byte swapping, leading to some confusing results. Specify the endianness explicitly so that the regmap core properly byte swaps the accesses for us.
