Subject: [PATCH v2 0/7] Add support for new SAI IP version
Date:   Sun, 28 Jul 2019 22:24:22 +0300
Message-Id: <20190728192429.1514-1-daniel.baluta@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

So far SAI IPs integrated with imx6 only supported one data line.
Starting with imx7 and imx8 SAI integration support up to 8 data
lines.

New SAI IP version introduces two new registers (Version and Parmeter
registers) which are placed at the beginning of register address space.
For this reason we need to fix the register's address.

Changes since v1:
	- removed patches from Lucas as they were already accepted
	- addressed comments from Lucas and Nicolin regarding
	device tree property naming
	- removed comment saying that "datalines" must be always
	consecutively enabled (this is not true, checked with IP owner)
	- added new patch to document newly introduced compatbile
	  strings
	- removed patch introducing combined mode as I will still need
	some time to figure out how to properly allow users to set it.

Nicolin,

Unfortunately I couldn't find any clean solution on handling registers
address shifts. As mentioned in patch 5/7 Tx/Rx data registers and
Tx/Rx FIFO registers keep their addresses while others are shifted
by 8 bytes.

Even if I could create two regmaps as suggested I will still need
to update each call of regmap_functions.

Daniel Baluta (7):
  ASoC: fsl_sai: Add registers definition for multiple datalines
  ASoC: fsl_sai: Update Tx/Rx channel enable mask
  ASoC: fsl_sai: Add support to enable multiple data lines
  ASoC: dt-bindings: Document dl-mask property
  ASoC: fsl_sai: Add support for SAI new version
  ASoC: fsl_sai: Add support for imx7ulp/imx8mq
  ASoC: dt-bindings: Introduce compatible strings for 7ULP and 8MQ
