2017-07-17powerpc/powernv: Fix boot on Power8 bare metal due to opal_configure_cores()Michael Ellerman
In commit 1c0eaf0f56d6 ("powerpc/powernv: Tell OPAL about our MMU mode on POWER9"), we added additional flags to the OPAL call to configure CPUs at boot. These flags only work on Power9 firmwares, and worse can cause boot failures on Power8 machines, so we check for CPU_FTR_ARCH_300 (aka POWER9) before adding the extra flags. Unfortunately we forgot that opal_configure_cores() is called before the CPU feature checks are dynamically patched, meaning the check always returns true. We definitely need to do something to make the CPU feature checks less prone to bugs like this, but for now the minimal fix is to use early_cpu_has_feature().

Provide the dynamic power coefficient of the big and little CPU clusters. These numbers are currently in use on the Samsung Chromebook Plus ("Kevin"). The power allocator thermal governor doesn't know how to do anything if it doesn't get power parameters from its cooling devices (in this case, CPUfreq). So this effectively enables the power-allocator governor. Signed-off-by: Brian Norris <briannorris@chromium.org> [set the property in each core node] Signed-off-by: Heiko Stuebner <heiko@sntech.de>
2017-07-16arm64: dts: rockchip: Use vctrl regulators for dynamic CPU voltages on Gru/KevinMatthias Kaehlcke
The Gru device tree currently contains entries for the regulators ppvar_bigcpu, ppvar_litcpu, ppvar_gpu and ppvar_centerlogic; however, the regulators have not been enabled, due to the lack of binding and driver support for keeping the over-voltage protection (OVP) at bay and preventing unintended regulator shutdowns on voltage downshifts. Now, the vctrl regulator driver has been merged, along with new bindings for asymmetric settling time. The driver is OVP aware, it splits larger voltage decreases in multiple steps when necessary and adds required delays. This change renames each of the aforementioned regulators to <orig_name>_pwm and adds a new vctrl regulator named <orig_name>. The vctrl regulators use the voltage of their corresponding PWM regulator as control voltage. The OVP related values are empirical and stem from the Chrome OS kernel tree.
