In the imx8qxp, the DMA is EDMA, which require the buffer size
should be divided by burst size with no remainder, otherwise
the remainder is not transferred by EDMA, so the input buffer
is not consumed by ASRC, then there will be dma output timeout
issue. This behavior is different with SDMA.
This patch is to change the input burst size to be 1 to avoid
the issue, and refine the last_period_size for output buffer.

We load DSP firmware from the ARM side at 0x556e8000 but because the
compiler generated memory layout starts at 0x596e8000 we need to do
some fixups.
Thus, each address (in DSP local memory) generated by the compiler
needs to be substracted an offset = 0x596e8000 - 0x556e8000 = 0x4000000.
Because this only happens on QM we will use dts to specify the offset.

Add two new message command I2S_TX_POINTER and I2S_RX_POINTER,
which are used to get the hw pointer in m4 side. For in low
power audio mode, m4 won't send notification every period, the
notification only be sent when hw pointer reach end of buffer,
so we need these command to get the position of hw pointer,
user can use it to calculate the timestamp.
Restructure send message and recv message together for i2s_rpmsg,
that every send message has a recv message. so the
i2s_send_message can store the recv message indepedently. one
reason is that the receive message is async withe send message.
The low power audio is disabled in default, user need to enabled
it by add "fsl,enable-lpa" in dts.

The dma_len is the size that how many data dma should transmit. As
the asrc use channel as unit, so the dma_len should also in channel unit.

Fixes commit feb06839682c ("MLK-16839-1: ASoC: fsl_asrc: selec
a proper clock source from the clock list")
When inclk is INCLK_ASRCK1_CLK, the driver will config module
to be non ideal ration mode, But the divider should be less
than 1024 and exact division. otherwise there will be distortion.
If the divider larger than 1024 or it is not exact division, asrc
should switch to ideal ratio mode, which don't care about the
divider.

The output size of asrc for a dedicate input is uncertain.
For example, if the input size is 1k, the output ratio is
2, so the output size should be 2k. but the actual output
size is not 2k, is less than 2k. if we set the dma size
to be 2k, the dma can't get enough data that can't finish
the transmission, then there will be
"output DMA task timeout"
So we need to set the dma size a proper value but we don't know
how many data less than expected. so we defined the last period
size for assumption of reduced size.
The last period size should not be too large, if it is large
there will be
"input DMA task timeout"
The reason is the output FIFO is full, which will block the
input data comsumption.
In this patch, the last period size is set to the difference
of configured buffer size and the expected output size, plus
a fix size.

The commit 7f3ff14b7eb1 ("dmaengine: imx-sdma: add 1ms delay
to ensure SDMA channel is stopped") add 1ms delay may cause
the audio underrun/overrun.
But ESAI has an hardware issue in older version which work abnormal
after underrun/overrun, especially there will be channel swap.
To workaround this issue, the ESAI need to be reset. in
imx-pcm-dma.c we include a new callback function for DMA interrupt
which will check the state of cpu dai and reset it in necessary.
So inport same function to imx-pcm-dma-v2.

Hardware Voice Activity Detector (HWVAD) is a block responsible for
detect voice activity in a channel selected by the user and it can be
configured in Envelope-based or Energy-based mode. Optionally, a
Zero-Crossing Detector can be enabled to improve the voice detection.
To enable hwvad from userspace there is a interface and you should write
the number of channels in /sys/devices/platform/30080000.micfil/hwvad/enable
to enable the hardware voice activity detection for micfil or 0
to disable it.
When voice activity is detected, an udev event will be generated:
"EVENT=PDM_VOICE_DETECT" and hwvad will be disabled afterwards.

Currently SAI master clock derives from an audio pll that cannot be
changed at runtime. iMX8 SoC has 2 audio plls usually configured to support
either 8000Hz (8k,16k,32k,48k,etc) or 11025Hz (11k,22k,44.1k,88.2k,etc)
ranges of rates - thus at runtime a SAI interface is able to play only one
range of rates. The patch allows dynamic SAI master clock reparenting to
the appropriate audio pll as function of the audio stream rate to be
played/recorded.
