Subject: [PATCH V1 0/3] ufs: ufs-qcom: Add support firmware managed platforms
Date: Fri, 14 Nov 2025 20:26:43 +0530 [thread overview]
Message-ID: <20251114145646.2291324-1-ram.dwivedi@oss.qualcomm.com> (raw)
From: Ram Kumar Dwivedi <quic_rdwivedi@quicinc.com>
On Qualcomm automotive SoC SA8255P, platform resource like clocks,
interconnect, resets, regulators and PHY are configured remotely by
firmware.
Logical power domain is used to abstract these resources in firmware
and SCMI power protocol is used to request resource operations by using
runtime PM framework APIs such as pm_runtime_get/put_sync to invoke
power_on/_off calls from kernel respectively.
