The renesas_usbhs driver doesn't use the clk functions. So, even if we
adds "CLKDEV_DEV_ID("renesas_usbhs.0", ...)" only, we cannot use the USB
controller because clk_late_init() will disable the clock by "usb0".
So, the patch also removes the "CLKDEV_CON_ID("usb0", ...)".

Add cache flushing code to the SH-Mobile specific CPU hotplug
implementation. While at it, add a cpu mask to make sure the
cache flushing code is finished in platform_cpu_die() before
letting the SoC-specific code in shmobile_platform_cpu_kill()
proceed with turning off power.
Without this code CPU hotplug offline fails when cache is
enabled on Cortex-A9 based SoCs.

Convert the low level SMP assembly code for SH-Mobile ARM
from using the INIT to the CPUINIT section. This unbreaks
onlining of CPUs using the CPU hotplug interface:
echo 1 > /sys/devices/system/cpu/cpu1/online
Without this fix the reset vector code used by CPU hotplug
will be freed as init section data and CPU cores cannot
be brought online.

To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console

This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface

Some SoCs have a timer block enable controlled through the DSCR registers.
There is a problem in the timer64 driver initialization where the code
accesses a timer register to get the divisor used to calculate timer clock
rate. If the timer block has not been enabled when this register read takes
place, an exception is generated. This patch makes sure that the timer block
is enabled before accessing the registers.

This reverts commit d5e553d6e0a4bdea43adae7373e3fa144b9a1aaa, which

This moves the #include <asm/asm-offsets.h> to <asm/syscall.h>, which
makes some kind of sense since NR_syscalls is syscalls related.
