sensors: add support for the BCM 4773 sensorhub

The Broadcom BCM4773 is a microcontroller that works as a
sensorhub. It's placed in between sensors and AP.

It's connected to the AP through SPI bus and has support for
a range of sensors:

 - icm20610
 - yas532
 - bmp182
 - tmg399x

The BCM4773 it can handle GPS and the gps driver is the main
entry point to the sensorhub driver as an SPI device.

7 years agousb: gadget: Allow to build both USB functions and legacy gadgets
Krzysztof Opasiak [Mon, 6 Jun 2016 19:40:33 +0000 (21:40 +0200)]
usb: gadget: Allow to build both USB functions and legacy gadgets

Currently it is possible to build in some subset of usb functions
*OR* some gadget module. This is limited only by Kconfig not
any functionality.

This patch removes this limitation. With this patch it is possible
to set up all build combinations:
1) Multiple gadgets build in
2) Part of functions build in, part of functions as a modules
3) Some gadgets build in and some part of functions build in/modules
etc.

As this patch makes Kconfig quite complicated let me clarify how it works:

USB_F_<func name> - used in makefile for compilation
USB_CONFIGFS_F_<func name> - Chosen by user in function menu
USB_G_<gadget name>_REQ_F_<func name> - set up by gadget to mark
      that this particular gadget requires this func to work
USB_F_<func name>_SELECTOR - helper config which is used to determine
    if function should be build in or compiled as a module

The rules are quite simple:
1) If any of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, then USB_F_<func name> is set to y and function is build in
2) If none of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, but any of them equals m then USB_F_<func name> is set to m and function
is compiled as a module

drm/exynos/decon5433: just return if decon is disable in decon_commit()

The decon_commit() can be called before decon is enabled if atomic
patches are applied at exynos drm, then it will cause kernel panic.
Already decon drm driver of mainline is considering this case.

7 years agocpuidle: Do not access cpuidle_devices when !CONFIG_CPU_IDLE

cpuidle: Do not access cpuidle_devices when !CONFIG_CPU_IDLE

The cpuidle_devices per-CPU variable is only defined when CPU_IDLE is
enabled. Commit c8cc7d4de7a4 ("sched/idle: Reorganize the idle loop")
removed the #ifdef CONFIG_CPU_IDLE around cpuidle_idle_call() with the
compiler optimising away __this_cpu_read(cpuidle_devices). However, with
CONFIG_UBSAN && !CONFIG_CPU_IDLE, this optimisation no longer happens
and the kernel fails to link since cpuidle_devices is not defined.

This patch introduces an accessor function for the current CPU cpuidle
device (returning NULL when !CONFIG_CPU_IDLE) and uses it in
cpuidle_idle_call().
