git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, including a couple of newly added drivers: - A new driver for the power management controller on TI Keystone - Support for the prerelease "SCPI" firmware protocol that ended up being shipped by Amlogic in their GXBB SoC. - A soc_device can now be matched using a glob from inside the kernel, when another driver wants to know the specific chip it is running on and cannot find out from DT, firmware or hardware. - Renesas SoCs now support identification through the soc_device interface, both in user space and kernel. - Renesas r8a7743 and r8a7745 gain support for their system controller - A new checking module for the ARM "PSCI" (not to be confused with "SCPI" mentioned above) firmware interface. - A new driver for the Tegra GMI memory interface - Support for the Tegra firmware interfaces with their power management controllers As usual, the updates for the reset controller framework are merged here, as they tend to touch multiple SoCs as well, including a new driver for the Oxford (now Broadcom) OX820 chip and the Tegra bpmp interface.

git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/drivers firmware: Add Tegra IVC and BPMP support IVC is an inter-processor communication protocol that uses shared memory to exchange data between processors. The BPMP driver makes use of this to communicate with the Boot and Power Management Processor (BPMP) and uses an additional hardware synchronization primitive from the HSP block to signal availability of new data (doorbell). Firmware running on the BPMP implements a number of services such as the control of clocks and resets within the system, or the ability to ungate or gate power partitions. * tag 'tegra-for-4.10-firmware' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: dt-bindings: firmware: Allow child nodes inside the Tegra BPMP dt-bindings: Add power domains to Tegra BPMP firmware firmware: tegra: Add BPMP support firmware: tegra: Add IVC library dt-bindings: firmware: Add bindings for Tegra BPMP Signed-off-by: Olof Johansson <olof@lixom.net>

This patch adds support for several power domains on Raspberry Pi, including USB (so it can be enabled even if the bootloader didn't do it), and graphics. This patch is the combined work of Eric Anholt (who wrote USB support inside of the Raspberry Pi firmware driver, and wrote the non-USB domain support) and Alexander Aring (who separated the original USB work out from the firmware driver).

2015-07-06soc: Mediatek: Add SCPSYS power domain driverSascha Hauer1-0/+15
This adds a power domain driver for the Mediatek SCPSYS unit. The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.
