This pull request contains the Raspberry Pi firmware driver, for communicating with the VPU which has exclusive control of some of the peripherals. Eric adds the actual firmware driver and Alexander fixes the header file which was missing include guards. * tag 'arm/soc/for-4.4/rpi-drivers' of https://github.com/Broadcom/stblinux: ARM: bcm2835: add mutual inclusion protection ARM: bcm2835: Add the Raspberry Pi firmware driver Signed-off-by: Olof Johansson

ARM: bcm2835: Add the Raspberry Pi firmware driver

This gives us a function for making mailbox property channel requests of the firmware, which is most notable in that it will let us get and set clock rates. Signed-off-by: Eric Anholt Acked-by: Stephen Warren

firmware: qcom-scm: build for correct architecture level

2015-10-14T19:51:22Z

The ".arch_extension sec" directive is only available on ARMv6 or higher, so if we enable the SCM driver while building a kernel for an older CPU, we get a build error: /tmp/ccUyhMOY.s:130: Error: selected processor does not support ARM mode `smc #0' /tmp/ccUyhMOY.s:216: Error: selected processor does not support ARM mode `smc #0' /tmp/ccUyhMOY.s:373: Error: selected processor does not support ARM mode `smc #0' make[4]: *** [drivers/firmware/qcom_scm-32.o] Error 1 This changes the Makefile so we pass the ARMv7 architecture level both for the check and for the actual compilation of the scm driver.

firmware: add support for ARM System Control and Power Interface(SCPI) protocol

2015-09-28T10:53:37Z

This patch adds support for System Control and Power Interface (SCPI) Message Protocol used between the Application Cores(AP) and the System Control Processor(SCP). The MHU peripheral provides a mechanism for inter-processor communication between SCP's M3 processor and AP. SCP offers control and management of the core/cluster power states, various power domain DVFS including the core/cluster, certain system clocks configuration, thermal sensors and many others. This protocol driver provides interface for all the client drivers using SCPI to make use of the features offered by the SCP.

arm64: psci: factor invocation code to drivers

2015-08-03T11:33:39Z

To enable sharing with arm, move the core PSCI framework code to drivers/firmware. This results in a minor gain in lines of code, but this will quickly be amortised by the removal of code currently duplicated in arch/arm.

MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/

2015-06-21T19:55:33Z

After Broadcom switched from MIPS to ARM for their home routers we need to have NVRAM driver in some common place (not arch/mips/). As explained in Kconfig, this driver is responsible for parsing SoC configuration data that is passed to the kernel in flash from the bootloader firmware called "CFE". We were thinking about putting it in bus directory, however there are two possible buses for MIPS: drivers/ssb/ and drivers/bcma/. So this won't fit there and this is why I would like to move this driver to the drivers/firmware/.
