Subject: [PATCH v2 2/3] reset: reset-meson: Add support for Amlogic T7 SoC reset controller
Date: Mon, 22 Apr 2024 19:11:44 +0800 [thread overview]
Message-ID: <20240422-t7-reset-v2-2-cb82271d3296@amlogic.com> (raw)
In-Reply-To: <20240422-t7-reset-v2-0-cb82271d3296@amlogic.com>
From: Zelong Dong <zelong.dong@amlogic.com>
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.
