Subject: [PATCH v4 0/2] ASoC: fsl_xcvr: Support i.MX95 platform

On i.MX95 wakeup domain, there is one instance of Audio XCVR
supporting SPDIF mode with a connection to the Audio XCVR physical
interface.

changes in v4:
- refine the constarint for 'clocks' according to Rob's comments

changes in v3:
- refine the constraint for 'resets', 'clocks', 'interrupts' in document.

changes in v2:
- Merge patch 1&2, 3&4 from v1 together.
- Add more comments in commit message
- Add constaint for clocks used on i.mx95
- Add 'select SND_SOC_FSL_UTILS' for compiling issue.

Subject: [PATCH v4 2/2] ASoC: fsl_xcvr: Add support for i.MX95 platform

On i.MX95, the XCVR uses a new PLL in the PHY, which is
General Purpose (GP) PLL. Add GP PLL configuration support
in the driver and add the 'pll_ver' flag to distinguish
different PLL on different platforms.

The XCVR also use PHY but limited for SPDIF only case
Add 'use_phy' flag to distinguish these platforms.

When there are 'pll8k' and 'pll11k' clock existing, the clock
source of 'phy_clk' can be changed for different sample rate
requirement.

Subject: [PATCH v4 1/2] ASoC: dt-bindings: fsl,xcvr: Add compatible string for i.MX95

Add compatible string "fsl,imx95-xcvr" for i.MX95 platform.

The difference between each platform is in below table.

+---------+--------+----------+--------+
| SOC | PHY | eARC/ARC | SPDIF |
+---------+--------+----------+--------+
| i.MX8MP | V1 | Yes | Yes |
+---------+--------+----------+--------+
| i.MX93 | N/A | N/A | Yes |
+---------+--------+----------+--------+
| i.MX95 | V2 | N/A | Yes |
+---------+--------+----------+--------+

On i.MX95, there are two PLL clock sources, they are the parent
clocks of the XCVR root clock. one is for 8kHz series rates, named
as 'pll8k', another one is for 11kHz series rates, named as 'pll11k'.
They are optional clocks, if there are such clocks, then the driver
can switch between them to support more accurate sample rates.

As 'pll8k' and 'pll11k' are optional, then add 'minItems: 4' for
clocks and clock-names properties.

On i.MX95, the 'interrupts' configuration has the same constraint
as i.MX93.

Only on i.MX8MP, the 'resets' is required, but for i.MX95 and i.MX93
there is no such hardware setting.

Thanks!

[1/2] ASoC: dt-bindings: fsl,xcvr: Add compatible string for i.MX95
commit: fc1277335ffa0d180c76ddccf5fe27fc75674e67
[2/2] ASoC: fsl_xcvr: Add support for i.MX95 platform
commit: f13b349e3c70320ef5a86edfc888a6feb612abb0

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
