Axel Lin 618718dc56 ASoC: qcom: Constify asoc_qcom_lpass_cpu_dai_ops
asoc_qcom_lpass_cpu_dai_ops is exported and used by multiple drivers,
make it const to prevent modifying it at run time.

Srinivas Kandagatla dc1ebd1811 ASoC: qcom: Add apq8016 lpass driver support
This patch adds apq8016 lpass driver support. APQ8016 has 4 MI2S which
can be routed to one internal codec and 2 external codec interfaces.

Primary, Secondary, Quaternary I2S can do Rx(playback) and Tertiary and
Quaternary can do Tx(capture).

Srinivas Kandagatla 89cdfa06d9 ASoC: qcom: add bit map to track static dma channel allocations
This patch adds dma channel bit mask to lpass data to keep track of dma
channel allocations. This flag would be used in apq8016 lpass driver.

Srinivas Kandagatla 4f629e4b87 ASoC: qcom: Add ability to handle interrupts per dma channel
This patch adds ablity to lpass driver to handle interrupt per dma
channel. Without this patch its not possible to use multipl ports on the
lpass.

Srinivas Kandagatla 0054055c59 ASoC: qcom: add dma channel control offset to variant data
This patch adds ability to pass dma channel control bits start offset,
which differ in differnet qcom SOCs. On apq8016 dma channel control bits
start after an offset of 1.

Srinivas Kandagatla 9a127cff91 ASoC: qcom: support bitclk and osrclk per i2s port
This patch adds support to allow bitclk and osrclk per i2s dai port.
on APQ8016 there are 4 i2s ports each one has its own bit clks.

Without this patch its not possible to support multiple i2s ports in the
lpass driver.

Srinivas Kandagatla 6db1c6ba95 ASoC: qcom: remove hardcoded dma channel
This patch removes hardcoded dma channel value in lpass driver, Now the
dma channel allocation happens in the SOC specific layer. This will
allow different LPASS integrations to use the lpass driver in more
generic way.

Srinivas Kandagatla 9bae4880ac ASoC: qcom: move ipq806x specific bits out of lpass driver.
This patch tries to make the lpass driver more generic by moving the
ipq806x specific bits out of the cpu and platform driver, also allows the
SOC specific drivers to add the correct register offsets.

This patch also renames the register definition header file into more
generic header file.

Kenneth Westfield cd59f13823 ASoC: qcom: add LPASS header files
Add the LPASS header files for ipq806x SOC.  This
includes the register definitions for the ipq806x
LPAIF, and the structure definition for the driver
data.
