With this patch we add documentation for: * power-management-unit: the PMU is used to bring up the cores during SMP operations * sram: among other things the sram is used to store the first code executed by the core when it is powered up * cpu-enable-method: the CPU enable method used by Amlogic Meson8 and Meson8b SoCs Signed-off-by: Carlo Caione <carlo@endlessm.com> [also add Meson8 to the documentation] Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Kevin Hilman <khilman@baylibre.com>

Amlogic Meson8 and Meson8b power-management-unit:
|
|
-------------------------------------------------
|
|
|
|
The pmu is used to turn off and on different power domains of the SoCs
|
|
This includes the power to the CPU cores.
|
|
|
|
Required node properties:
|
|
- compatible value : depending on the SoC this should be one of:
|
|
"amlogic,meson8-pmu"
|
|
"amlogic,meson8b-pmu"
|
|
- reg : physical base address and the size of the registers window
|
|
|
|
Example:
|
|
|
|
pmu@c81000e4 {
|
|
compatible = "amlogic,meson8b-pmu", "syscon";
|
|
reg = <0xc81000e0 0x18>;
|
|
};
