Subject: [PATCH 3/3] soc: qcom: pmic_glink: Add PDR service path and service name to client data
Currently, the charger PD service path and service name are hard coded
however these paths are not guaranteed to be the same between PMICs. For
example, on Kaanapali, Charger FW runs on SOCCP(another subsystem) which
does not have any specific charger PDs defined.
Define PDR service path and service name as client data so that each
PMIC generation can properly define these paths.
While at it, add the qcom,kaanapali-pmic-glink compatible string.
