Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm

2015-06-26T19:20:00+00:00

Pull ARM updates from Russell King:
 "Bigger items included in this update are:

   - A series of updates from Arnd for ARM randconfig build failures
   - Updates from Dmitry for StrongARM SA-1100 to move IRQ handling to
     drivers/irqchip/
   - Move ARMs SP804 timer to drivers/clocksource/
   - Perf updates from Mark Rutland in preparation to move the ARM perf
     code into drivers/ so it can be shared with ARM64.
   - MCPM updates from Nicolas
   - Add support for taking platform serial number from DT
   - Re-implement Keystone2 physical address space switch to conform to
     architecture requirements
   - Clean up ARMv7 LPAE code, which goes in hand with the Keystone2
     changes.
   - L2C cleanups to avoid unlocking caches if we're prevented by the
     secure support to unlock.
   - Avoid cleaning a potentially dirty cache containing stale data on
     CPU initialisation
   - Add ARM-only entry point for secondary startup (for machines that
     can only call into a Thumb kernel in ARM mode).  Same thing is also
     done for the resume entry point.
   - Provide arch_irqs_disabled via asm-generic
   - Enlarge ARMv7M vector table
   - Always use BFD linker for VDSO, as gold doesn't accept some of the
     options we need.
   - Fix an incorrect BSYM (for Thumb symbols) usage, and convert all
     BSYM compiler macros to a "badr" (for branch address).
   - Shut up compiler warnings provoked by our cmpxchg() implementation.
   - Ensure bad xchg sizes fail to link"

clockevents/drivers: Add STM32 Timer driver

2015-06-02T10:10:15+00:00

STM32 MCUs feature 16 and 32 bits general purpose timers with prescalers.
The drivers detects whether the time is 16 or 32 bits, and applies a
1024 prescaler value if it is 16 bits.

clocksource/drivers/lpc32xx: Add the lpc32xx timer driver

2015-06-02T10:10:10+00:00

Add support for using the NXP LPC timer as clocksource and clock
event. These timers are present on many NXP devices including
LPC32xx, LPC17xx, LPC18xx and LPC43xx.

The timer has a 32-bit timer counter register with a programmable
32-bit prescaler. It supports up to 4 compare match values with
interrupt generation and reset/stop timer counter action.

ARM: 8366/1: move Dual-Timer SP804 driver to drivers/clocksource

2015-06-02T08:58:18+00:00

The ARM Dual-Timer SP804 module is peripheral found not only on ARM32
platforms but also on ARM64 platforms.

This patch moves the driver out of arch/arm to driver/clocksource
so that it can be used on ARM64 platforms also.
