The personal aim is to upstream MSM8956 as much as possible. This code has been tested on two Sony phones featuring the Qualcomm MSM8956 SoC. Changes in v2: - Fixed optional properties placement in documentation Changes in v3: - Rebased onto linux-next 01/10/2019 - Added missing SCM commit (required by the AArch64 PT switch support) Changes in v4: - Removed rej files from the SCM patch (I'm truly sorry for the noise...)
