Subject: [PATCH] soc: imx: gpc: fix PDN delay
Git-commit: 9f4d61d531e0efc9c3283963ae5ef7e314579191
Patch-mainline: v4.20-rc1
References: bsc#1051510

imx6_pm_domain_power_off() reads iso and iso2sw from GPC_PGC_PUPSCR_OFFS
which stores the power up delays.
So use GPC_PGC_PDNSCR_OFFS for the correct delays.
