10 - Konrad Dybcio <konrad.dybcio@linaro.org>
15 spanning a single subsystem (e.g. APSS, ADSP, CDSP). All of the RPM decisions
16 (particularly around entering hardware-driven low power modes: XO shutdown
17 and total system-wide power collapse) are first made at Master-level, and
20 The Master Stats provide a few useful bits that can be used to assess whether
21 our device has entered the desired low-power mode, how long it took to do so,
26 This scheme has been used on various SoCs in the 2013-2023 era, with some
27 newer or higher-end designs providing this information through an SMEM query.
