Subject: [PATCH RFC 00/15] Convert Qualcomm RPM message RAM to a simple-mfd
Date: Sat, 11 Mar 2023 02:21:30 +0100 [thread overview]
Message-ID: <20230311-topic-msg_ram-v1-0-e9c2094daf09@linaro.org> (raw)
The Qualcomm RPM message RAM is a part of the RPM low-power processor's
actual RAM that's exposed to the Application Processors as a MMIO-mapped
region. It contains a couple of things, most notably the RPM master stats,
detailing per-master (read: per-subsystem) sleep/wake statistics and an
interrupt controller that's crucial to achieving full SoC clock and/or
power collapse states (the MPM). This series tries to prepare the MSG
RAM node to be a host for such devices.
Depends on https://lore.kernel.org/linux-arm-msm/20230308011705.291337-1-konrad.dybcio@linaro.org/
to solve a warning in the example.
The DTS commits don't add -cells or -ranges, as without children they're
not of very much use. They'll be introduced along with subnodes.
