From b062ef2907a2f2054d7b3f84712e12ace42ee3f1 Mon Sep 17 00:00:00 2001 From: Zelong Dong Date: Mon, 22 Apr 2024 19:11:44 +0800 Subject: [PATCH] reset: reset-meson: Add support for Amlogic T7 SoC reset controller There are 7 sets of Reset Source in Amlogic T7 SoC reset controller, and the offset between base and level registers is 0x40. Add a new compatible string and struct meson_reset_param to support the reset controller on T7 SoC.
