[PATCH 0/8] soc: qcom: Add compatibles for MSM8909

[Stephan Gerhold]

A set of tiny patches adding compatibles for MSM8909 in Qualcomm SoC
drivers. Most of them are even just aliases for existing code (usually
MSM8916 since it is very similar).

Subsystem Power Manager (SPM) on the MSM8909 SoC. This is necessary

[PATCH 6/8] soc: qcom: spm: Add CPU data for MSM8909

[Stephan Gerhold]

Given the lack of public documentation for the SPM, the configuration
data is taken without modification from Qualcomm's msm-3.10 release [1].
It is pretty much identical to the one for MSM8916, except that 0x3B is
missing in the sequence for standalone power collapse for some reason.

[PATCH 7/8] dt-bindings: arm: cpus: Document "qcom,msm8909-smp" enable-method

[Stephan Gerhold]

MSM8909 is a fairly old 32-bit SoC without PSCI support, so the
additional CPU cores need to be initialized with a custom enable-method.
Fortunately it works just like on MSM8226 and MSM8916 so just add
an additional compatible as alias to the DT schema.
