** ** NOTE: To "view the full picture", please look at the following ** patch series: ** https://patchwork.kernel.org/project/linux-arm-msm/list/?series=413355 ** This is a subset of that series. ** Changes in v4: - Huge patch series has been split for better reviewability, as suggested by Bjorn - Rebased code on top of 266991721c15 ("cpufreq: qcom-hw: enable boost support") Changes in v3: - Fixed a test robot build failure for ARCH=arm - Fixed dt_binding_check YAML doc issues Changes in v2: - Rebased dt-binding on top of Manivannan's patches - Added MSM8998 to cpufreq-dt-platdev blacklist - Implemented dynamic Memory Accelerator corners support, needed by MSM8998 - Implemented ACD programming, needed by MSM8998 Tested on the following smartphones: - Sony Xperia XA2 (SDM630) - Sony Xperia XA2 Ultra (SDM630) - Sony Xperia 10 (SDM630) - Sony Xperia XZ Premium (MSM8998) - F(x)Tec Pro 1 (MSM8998) >From SDM845 onwards, SAW, CPRh and OSM are getting setup by the bootloader/TZ *before* booting the OS, so then all the OS has to do is to request a specific performance state to the OSM hardware and forget about all the rest, which is anyway protected by the hypervisor (so there's no access anyway); BUT: In MSM/APQ 8998, SDM/SDA 630/636/660 (and other variants), there is no setup of any of these puzzle pieces, and they're also (basically) fully accessible, which means that the OS must do it in order to get in the same state as the newer ones and to get the entire scaling hardware to start rolling.
