Subject: [PATCH v6 2/7] soc: rockchip: add header for suspend mode SIP interface
Date: Tue, 21 Jan 2025 11:00:22 +0800 [thread overview]
Message-ID: <1737428427-32393-3-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1737428427-32393-1-git-send-email-shawn.lin@rock-chips.com>
Add ROCKCHIP_SIP_SUSPEND_MODE to pass down parameters to Trusted Firmware
in order to decide suspend mode. Currently only add ROCKCHIP_SLEEP_PD_CONFIG
which teaches firmware to power down controllers or not.
