Subject: [PATCH v6 5/5] ARM: dtsi: aspeed: Modified gfx reset control
Date: Wed, 2 Mar 2022 10:49:30 +0800 [thread overview]
Message-ID: <20220302024930.18758-6-tommy_huang@aspeedtech.com> (raw)
In-Reply-To: <20220302024930.18758-1-tommy_huang@aspeedtech.com>
Remove the ast2500-gfx from aspeed-g6.dtsi.
In the AST2600, the ASPEED_RESET_CRT1 is replaced by
ASPEED_RESET_GRAPHICS. This is no differnce between these two reset
behavior but reigster location is changed. The HW controller states
and FW programming resgiter will be reset by CRT reset controller bit
(SCU040[13]). And another part HW controller will be reset by
Graphics controller bit (SCU040[26]). These two reset bit need be
de-assert then the SOC display will be active.
