From a20be24cd4854fb829384f9b45742f7f5d9046c8 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 9 Dec 2022 20:35:47 +0100 Subject: [PATCH] ARM: imx: Remove PMIC reset configuration from board files The PCA9450 reset configuration can now be performed by the PCA9450 PMIC driver itself, remove the hard-coded variant from board code and let the PMIC driver perform this task using one-liner: ``` $ sed -i '/set WDOG_B_CFG to cold reset/,+2 d' $(git grep -l PCA9450_RESET_CTRL.*0xA1 board/) ``` Venice and i.MX93 EVK required slight manual fix up.
