From ad8cc071c557b075b923bf27aee8a7dae7338f5e Mon Sep 17 00:00:00 2001 From: Aisheng Dong Date: Wed, 20 Feb 2019 14:38:32 +0000 Subject: firmware: imx: scu-pd: add specifying the base of domain name index support As the domain resource id in the same type may not be continuous, so it's hard to describe all such power domains with current struct imx_sc_pd_range. Adding the optional base for domain name index to address this issue. Then we can add the discrete domains easily later. Cc: Ulf Hansson Cc: Shawn Guo Cc: Sascha Hauer Cc: "Rafael J.
