Subject: [PATCH 3/3] pmdomain: qcom: rpmhpd: Add RPMh power domain support
 for Kaanapali

From: Jishnu Prakash <jishnu.prakash@....qualcomm.com>

Add the RPMh power domains present in Kaanapali SoCs. Also increase the
maximum allowed number of levels for ARC resources from 16 to 32, as
needed starting on the Kaanapali SoC where the ARC vote registers have been
expanded from 4 to 5 bits.
