2015-09-03drm/i915: Add locks around audio component bind/unbindDavid Henningsson
This will make sure that audio callbacks do not race with component bind/unbind.

2015-09-03MIPS: UAPI: Fix unrecognized opcode WSBH/DSBH/DSHD when using MIPS16.Yousong Zhou
The nomips16 has to be added both as function attribute and assembler directive. When only function attribute is specified, the compiler will inline the function with -Os optimization. The generated assembly code cannot be correctly assembled because ISA mode switch has to be done through jump instruction. When only ".set nomips16" directive is used, the generated assembly code will use MIPS32 code for the inline assembly template and MIPS16 for the function return. The compiled binary is invalid: 00403100 <__arch_swab16>: 403100: 7c0410a0 wsbh v0,a0 403104: e820ea31 swc2 $0,-5583(at) while correct code should be: 00402650 <__arch_swab16>: 402650: 7c0410a0 wsbh v0,a0 402654: 03e00008 jr ra 402658: 3042ffff andi v0,v0,0xffff Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> Cc: Chen Jie <chenj@lemote.com> Cc: linux-mips@linux-mips.org Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/11087/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2015-09-03CLOCKSOURCE: Add Pistachio clocksource-only driverEzequiel Garcia
The Pistachio SoC provides four general purpose timers, and allow to implement a clocksource driver. This driver can be used as a replacement for the MIPS GIC and MIPS R4K clocksources and sched clocks, which are clocked from the CPU clock. Given the general purpose timers are clocked from an independent clock, this new clocksource driver will be useful to introduce CPUFreq support for Pistachio machines.

2015-09-03CLOCKSOURCE: mips-gic: Split clocksource and clockevent initializationEzequiel Garcia
This is preparation work for the introduction of clockevent frequency update with a clock notifier. This is only possible when the device is passed a clk struct, so let's split the legacy and devicetree initialization.

2015-09-03CLOCKSOURCE: mips-gic: Enable the clock before using itEzequiel Garcia
For the clock to be used (e.g. get its rate through clk_get_rate) it should be prepared and enabled first. Also, while the clock is enabled the driver must hold a reference to it, so let's remove the call to clk_put.

2015-09-03MIPS: Tidy up FPU context switchingPaul Burton
Rather than saving the scalar FP or vector context in the assembly resume function, reuse the existing C code we have in fpu.h to do exactly that. This reduces duplication, results in a much easier to read resume function & should allow the compiler to optimise out more MSA code due to is_msa_enabled()/cpu_has_msa being known-zero at compile time for kernels without MSA support.

2015-09-03MIPS: Remove all the uses of custom gpio.hAlban Bedel
Currently CONFIG_ARCH_HAVE_CUSTOM_GPIO_H is defined for all MIPS machines, and each machine type provides its own gpio.h. However only a handful really implement the GPIO API, most just forward everythings to gpiolib. The Alchemy machine is notable as it provides a system to allow implementing the GPIO API at the board level. But it is not used by any board currently supported, so it can also be removed. For most machine types we can just remove the custom gpio.h, as well as the custom wrappers if some exists. Some of the code found in the wrappers must be moved to the respective GPIO driver. A few more fixes are need in some drivers as they rely on linux/gpio.h to provides some machine specific definitions, or used asm/gpio.h instead of linux/gpio.h for the gpio API.
