Subject: [PATCH v3 1/2] ASoC: dt-bindings: fsl,xcvr: Add compatible string for i.MX95
Date: Tue, 21 May 2024 18:13:35 +0800

In-Reply-To: <1716286416-17621-1-git-send-email-shengjiu.wang@nxp.com>

Precedence: bulk

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.
