Subject: [PATCH v5 04/10] soc: mediatek: cmdq: Add cmdq_pkt_write_s_reg_value to support write value to reg
Date: Wed, 3 Apr 2024 18:25:56 +0800 [thread overview]
Message-ID: <20240403102602.32155-5-shawn.sung@mediatek.com> (raw)
In-Reply-To: <20240403102602.32155-1-shawn.sung@mediatek.com>
From: "Jason-JH.Lin" <jason-jh.lin@mediatek.com>
Add cmdq_pkt_write_s_reg_value to support write a value to a register.
It appends write_s command to the command buffer in a CMDQ packet,
ask GCE to excute a write instruction to write a value to a register
with low 16 bits physical address offset.
