Subject: [PATCH 0/2] Extend nvmem patternProperties and then fix W=1
 warnings in Apple dts

Hi,

This brief series fixes a W=1 warning recently introduced with the Apple
Silicon PMIC NVMEM nodes. We have cells that are the same bytes but a
different bit offset and these currently result in the same node name.
The legcy layout already allows to specify the bit offset in the name as
a suffix but this isn't possible in the new fixed-layout.
Thus first adjust the fixed-layout cell patternProperties to the same pattern
as the legacy one and then fix the node names in our device tree files.

Best,

Sven
