Linus Torvalds 807249d3ad Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for 4.3 for MIPS.  Here's the summary:

  Three fixes that didn't make 4.2-stable:

   - a -Os build might compile the kernel using the MIPS16 instruction
     set but the R2 optimized inline functions in <uapi/asm/swab.h> are
     implemented using 32-bit wide instructions which is invalid.

   - a build error in pgtable-bits.h for a particular kernel
     configuration.

   - accessing registers of the CM GCR might have been compiled to use
     64 bit accesses but these registers are onl 32 bit wide.

  And also a few new bits:

   - move the ATH79 GPIO driver to drivers/gpio

   - the definition of IRQCHIP_DECLARE has moved to linux/irqchip.h,
     change ATH79 accordingly.

   - fix definition of pgprot_writecombine

   - add an implementation of dma_map_ops.mmap

   - fix alignment of quiet build output for vmlinuz link

   - BCM47xx: Use kmemdup rather than duplicating its implementation

   - Netlogic: Fix 0x0x prefixes of constants.

   - merge Bjorn Helgaas' series to remove most of the weak keywords
     from function declarations.

   - CP0 and CP1 registers are best considered treated as unsigned
     values to avoid large values from becoming negative values.

   - improve support for the MIPS GIC timer.

   - enable common clock framework for Malta and SEAD3.

   - a number of improvments and fixes to dump_tlb().

   - document the MIPS TLB dump functionality in Magic SysRq.

   - Cavium Octeon CN68XX improvments.

   - NetLogic improvments.

   - irq: Use access helper irq_data_get_affinity_mask.

   - handle MSA unaligned accesses.

   - a number of R6-related math-emu fixes.

   - support for I6400.

   - improvments to MSA support.

   - add uprobes support.

   - move from deprecated __initcall to arch_initcall.

   - remove finish_arch_switch().

   - IRQ cleanups by Thomas Gleixner.

   - migrate to new 'set-state' interface.

   - random small cleanups"

Ezequiel Garcia 84583983c3 CLOCKSOURCE: Add Pistachio clocksource-only driver
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.

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.

moved initialization parameters into a data structure, but neglected to set
the irq field in that data structure for non-DT boots. This causes the system

Viresh Kumar daea72831d clockevents/drivers/timer-sp804: Migrate to new 'set-state' interface
Migrate timer-sp driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

There are few more changes worth noticing:

- The clockevent device was disabled by writing: 'TIMER_CTRL_32BIT |
  TIMER_CTRL_IE' to ctrl register earlier. i.e. by un-setting the
  TIMER_CTRL_ENABLE bit. Its done by writing zero now and should have
  the same effect.

- For shutdown and resume we were writing the same value twice to the
  register (to disable the timer), which is fixed now.

- Switching to oneshot mode was divided into two parts earlier:
  - Firstly set_mode() was writing:
    'TIMER_CTRL_32BIT | TIMER_CTRL_IE | TIMER_CTRL_ONESHOT'
    to ctrl register (device not enabled yet)
  - Then sp804_set_next_event() was enabling the device by writing
    'readl(ctrl) | TIMER_CTRL_ENABLE' to the ctrl register. This was
    unnecessarily complicated.
  - Change this to: Stop device on set_state_oneshot and configure it in
    sp804_set_next_event().

Viresh Kumar 26b91f043a clockevents/drivers/timer-imx-gpt: Migrate to new 'set-state' interface
Migrate timer-imx-gpt driver to the new 'set-state' interface provided
by clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

Also drop:
- 'imx_timer.cem': It was caching the last state of the clockevent
  device. The same behavior can be achieved by using clockevents state
  helpers. These helpers are only required for oneshot mode as
  shutdown/resume wouldn't be done twice by the core.

- 'clock_event_mode_label': CLOCK_EVT_MODE_* shouldn't be used anymore
  by drivers. The prints are modified to print the set-state functions
  name now to debug the driver.

Geert Uytterhoeven 8c436f8480 clockevents/drivers/sh_cmt: Remove obsolete sh-cmt-48 platform_device_id entry
Since the removal of the r8a7740 legacy SoC code in commit
44d88c754e ("ARM: shmobile: Remove legacy SoC code for R-Mobile
A1"), all former users of the "sh-cmt-48-gen2" platform device name are
only supported in generic DT-only ARM multi-platform builds.  The driver
doesn't need to match platform devices by name anymore, hence remove the
corresponding platform_device_id entry.

Jisheng Zhang 8b5f0010fe clockevents/drivers/dw_apb_timer: Add dynamic irq flag to the timer
Commit d2348fb6fd ("tick: Dynamically set broadcast irq affinity")
adds one excellent feature CLOCK_EVT_FEAT_DYNIRQ to let the core set the
interrupt affinity of the broadcast interrupt to the cpu which has the
earliest expiry time. This patch adds CLOCK_EVT_FEAT_DYNIRQ flag to
avoid unnecessary wakeups and IPIs when the dw_apb_timer is used as
broadcast timer.

A simple test:
~ # rm /tmp/test.sh
~ # cat > /tmp/test.sh
cat /proc/interrupts
for i in `seq 10` ; do sleep $i; done
cat /proc/interrupts
~ # chmod +x /tmp/test.sh
~ # taskset 0x2 /tmp/test.sh

There is nothing to be done for resume state and so isn't implemented.
