Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC,
It supports both I2S/I2C and SLIMbus audio interfaces.
On slimbus interface it supports two data lanes; 16 Tx ports
and 8 Rx ports. It has Seven DACs and nine dedicated interpolators,
Seven (six audio ADCs, and one VBAT ADC), Multibutton headset
control (MBHC), Active noise cancellation and Sidetone paths
and processing.

This patchset adds very basic support for playback and capture
via the 9 interpolators and ADC respectively.

There is a potential execution path in which function
platform_get_resource() returns NULL. If this happens,
we will end up having a NULL pointer dereference.

Fix this by replacing devm_ioremap with devm_ioremap_resource,
which has the NULL check and the memory region request.

This code was detected with the help of Coccinelle.

The conversion from PCM format type to bits needs an explicit cast,
and it'll be uglier.  Since we have a standard macro for that, let's
use it instead.

This patch fixes the sparse warning:

The PCM format type is with __bitwise, so we should use the dedicated
snd_pcm_format_t instead of int.

As sparse warns, the PCM format type can't be dealt as integer as
found in Intel SST driver codes.

Fix them in the following two ways:

- The open code with snd_mask_set() and params->masks reference is
  replaced with params_set_format()

- The rest codes with snd_mask_set(fmt, SNDRV_PCM_FORMAT_XXX) are
  replaced with the new helper, snd_mask_set_format().

It seems that __user prefix was forgotten to be added to
dmaengine_copy_user callback while we refactored the user-copy PCM
core.

This patch adds the missing prefix, remove the superfluous cast, and
add the needed cast (__force is needed for downgrading from user
pointer to kernel pointer), too.

Add Amlogic's axg TDM interface driver. This driver manages the format
and clocks provided on the pads.

On this SoC, each stream direction provides 4 serial lanes. This makes
a maximum of 8 channels in i2s modes and 128 channels in DSP modes.

While each lanes operate on the same slot number (same bit clock), they
may have different TDM masks. This requires to provide a function to let
the card set the 4 masks, in lieu of the usual set_tdm_slots() callback
of the dai driver.
