[PATCH v2 1/2] i3c: master: svc: fix compatibility string mismatch with binding doc

[PATCH v2 1/2] i3c: master: svc: fix compatibility string mismatch with binding doc

[Frank Li]

In the binding documentation, the compatible string is specified as
'silvaco,i3c-master-v1', but in the driver, it is defined as
'silvaco,i3c-master'.

Rename 'silvaco,i3c-master' to 'silvaco,i3c-master-v1' to ensure
compatibility with the documentation.

Notes:
    Change from v2 to v3
    - Miquèl think drop silvaco,i3c-master totally. I grep dts tree. No
    upstream dts use silvaco,i3c-master yet.
      I have not add "Reviewed-by: Miquel Raynal <miquel.raynal@bootlin.com>",
    it is different solution with previous one even just one line change.
      I think v2/v3 both is good, feel free to pick each one.
    
    Change from v1 to v2
    - update driver by using compatible string silvaco,i3c-master-v1

Rob had a comment [1] about SoC specific compatible.  That's not what we
want?

Yeah, Rob's request here looks valid to me. Should just be a bindings
change Frank & fall back to the "silvaco,i3c-master-v1" compatible.

Cheers,
Conor.

Hmm, not sure I have seen that.  Here is what I saw from Rob:

"
The real problem here is not whether we have "v1" or not, but you need
an SoC specific compatible. Unless there's a public spec where we can
know exactly how many resets, clocks, interrupts, etc.
"

@Rob:
	Previous existed binding doc is "silvaco,i3c-master-v1". So far
this IP in our difference SOC have the same resets and clocks, and only one
interrrupts.
	current existed i3c controller compatible string is

	snps,dw-i3c-master-1.00a
	cdns,i3c-master
	mipi-i3c-hci

	mipi-i3c-hci is standard. "snps", "cdns" are similar as prefix
"silivaco".
	I think the same IP vendor and same IP version should have same
resets, clocks, and interrupts. So far still not met exception yet.
