[PATCH v5 1/2] regulator: dt-bindings: pca9450: Add nxp,pf9453 compatible string

From: Frank Li
Date: Fri Mar 14 2025 - 11:24:28 EST


Add the compatible string "nxp,pf9453" for the PF9453 regulator. The PF9453
is similar to the PCA9460 but supports only LDO1, LDO2, LDO_SVNS, and
BUCK[1-4].

Restrict LDO and BUCK numbers for nxp,pf9453 and keep the same restriction
for other compatible strings.

Change form v3 to v4
- rebase to regualtor/for-next
- last upstream remove LDO5, so remove LDO5 for nxp,pf9453 also.

change from v2 to v3
- LDO_SNVS to LDO-SNVS
