Subject: [PATCH v2 0/2] Support Tegra I2S client format conversion

From: Mohan Kumar <mkumard@...dia.com>

The AHUB HW modules are interconnected with CIF which are capable of
supporting Channel and Sample bit format conversion. Due to this, the
I2S Client can have different Channel and Sample bit from the hw_params()
and this config is passed from CIF port of I2S DT node which can help to
perform this conversion.

- First change to split simple_fixup_sample_fmt to support returning
  sample format value
- Second patch to support Tegra I2S client channel and sample format
  programming based on CIF port from DT node.


Changelog
=========
  v2:
    - Fix sparse warning related to incorrect type assignment for
      variable 'sample_format' in hw_params() call. The defect was
      reported by "kernel test robot <lkp@...el.com>" and details
      can be found below:
