740fbddf5c watchdog: sp5100_tco: Add SB8x0 chipset support
The current sp5100_tco driver only supports SP5100/SB7x0 chipset, doesn't
support SB8x0 chipset, because current sp5100_tco driver doesn't know that the
offset address for watchdog timer was changed from SB8x0 chipset.

The offset address of SP5100 and SB7x0 chipsets are as follows, quote from the
AMD SB700/710/750 Register Reference Guide (Page 164) and the AMD SP5100
Register Reference Guide (Page 166).

  WatchDogTimerControl 69h
  WatchDogTimerBase0   6Ch
  WatchDogTimerBase1   6Dh
  WatchDogTimerBase2   6Eh
  WatchDogTimerBase3   6Fh

In contrast, the offset address of SB8x0 chipset is as follows, quote from
AMD SB800-Series Southbridges Register Reference Guide (Page 147).

  WatchDogTimerEn      48h
  WatchDogTimerConfig  4Ch

So, In the case of SB8x0 chipset, sp5100_tco reads meaningless MMIO
address (for example, 0xbafe00) from wrong offset address, and the following
message is logged.

   SP5100 TCO timer: mmio address 0xbafe00 already in use

With this patch, sp5100_tco driver supports SB8x0 chipset, and can avoid
iomem resource conflict. The processing of this patch is as follows.

 Step 1) Attempt to get the watchdog base address from indirect I/O (0xCD6
         and 0xCD7).
  - Go to the step 7 if obtained address hasn't conflicted with other
    resource. But, currently, the address (0xfec000f0) conflicts with the
    IOAPIC MMIO address, and the following message is logged.

       SP5100 TCO timer: mmio address 0xfec000f0 already in use

    0xfec000f0 is recommended by AMD BIOS Developer's Guide. So, go to the
    next step.

 Step 2) Attempt to get the SBResource_MMIO base address from AcpiMmioEN (for
         SB8x0,  PM_Reg:24h) or SBResource_MMIO (SP5100/SB7x0, PCI_Reg:9Ch)
         register.
  - Go to the step 7 if these register has enabled by BIOS, and obtained
    address hasn't conflicted with other resource.
  - If above condition isn't true, go to the next step.

 Step 3) Attempt to get the free MMIO address from allocate_resource().
  - Go to the step 7 if these register has enabled by BIOS, and obtained
    address hasn't conflicted with other resource.
  - Driver initialization has failed if obtained address has conflicted
    with other resource, and no 'force_addr' parameter is specified.

 Step 4) Use the specified address If 'force_addr' parameter is specified.
  - allocate_resource() function may fail, when the PCI bridge device occupies
    iomem resource from 0xf0000000 to 0xffffffff. To handle such a case,
    I added 'force_addr' parameter to sp5100_tco driver. With 'force_addr'
    parameter, sp5100_tco driver directly can assign MMIO address for watchdog
    timer from free iomem region. Note that It's dangerous to specify wrong
    address in the 'force_addr' parameter.

      Example of force_addr parameter use
        # cat /proc/iomem
        ...snip...
        fec00000-fec003ff : IOAPIC 0
                                      <--- free MMIO region
        fec10000-fec1001f : pnp 00:0b
        fec20000-fec203ff : IOAPIC 1
        ...snip...
        # cat /etc/modprobe.d/sp5100_tco.conf
        options sp5100_tco force_addr=0xfec00800
        # modprobe sp5100_tco
        # cat /proc/iomem
        ...snip...
        fec00000-fec003ff : IOAPIC 0
        fec00800-fec00807 : SP5100 TCO  <--- watchdog timer MMIO address
        fec10000-fec1001f : pnp 00:0b
        fec20000-fec203ff : IOAPIC 1
        ...snip...
        #

  - Driver initialization has failed if specified address has conflicted
    with other resource.

 Step 5) Disable the watchdog timer
  - To rewrite the watchdog timer register of the chipset, absolutely
    guarantee that the watchdog timer is disabled.

 Step 6) Re-program the watchdog timer MMIO address to chipset.
  - Re-program the obtained MMIO address in Step 3 or Step 4 to chipset via
    indirect I/O (0xCD6 and 0xCD7).

 Step 7) Enable and setup the watchdog timer

This patch has worked fine on my test environment (ASUS M4A89GTD-PRO/USB3 and
DL165G7). therefore I believe that it's no problem to re-program the MMIO
address for watchdog timer to chipset during disabled watchdog. However,
I'm not sure about it, because I don't know much about chipset programming.

So, any comments will be welcome.

5235f57a6f davinci_wdt: preparation for switch to common clock framework
As a first step towards migrating davinci platforms to use common clock
framework, replace all instances of clk_enable() with clk_prepare_enable()
and clk_disable() with clk_disable_unprepare(). Until the platform is
switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just
adds a might_sleep() call and would work without any issues.

This will make it easy later to switch to common clk based implementation
of clk driver from DaVinci specific driver.

Continued device tree conversion and enablement across a number of
 platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other

 ux500 has seen continued conversion for platforms. Several platforms have
 seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra
 is adding data for new devices/drivers, and Exynos has a bunch of new
 bindings and devices added as well.
 
 So, pretty much the same progression in the right direction as the last
 few releases.

129f557723 watchdog: OMAP: use standard GETBOOTSTATUS interface; use platform_data fn ptr
Previously the OMAP watchdog driver used a non-standard way to report
the chip reset source via the GETBOOTSTATUS ioctl.  This patch
converts the driver to use the standard WDIOF_* flags for this
purpose.

This patch may break existing userspace code that uses the existing
non-standard data format returned by the OMAP watchdog driver's
GETBOOTSTATUS ioctl.  To fetch detailed reset source information,
userspace code will need to retrieve it directly from the CGRM or PRM
drivers when those are completed.

Previously, to fetch the reset source, the driver either read a
register outside the watchdog IP block (OMAP1), or called a function
exported directly from arch/arm/mach-omap2.  Both approaches are
broken.  This patch also converts the driver to use a platform_data
function pointer.  This approach is temporary, and is due to the lack
of drivers for the OMAP16xx+ Clock Generation and Reset Management IP
block and the OMAP2+ Power and Reset Management IP block.  Once
drivers are available for those IP blocks, the watchdog driver can be
converted to call exported functions from those drivers directly.
At that point, the platform_data function pointer can be removed.

In the short term, this patch is needed to allow the PRM code to be
removed from arch/arm/mach-omap2 (it is being moved to a driver).

This version integrates a fix from Jon Hunter <jon-hunter@ti.com>
that avoids a NULL pointer dereference in a DT-only boot, and integrates
a patch commit message fix from Felipe Balbi <balbi@ti.com>.

578f1ef91a MFD bits for the 3.7 merge window.
As usual we have a few new drivers:
 
 - TI LP8788
 - TI OMAP USB TLL
 - Maxim MAX8907
 - SMSC ECE1099
 - Dialog Semiconductor DA9055
 - A simpler syscon driver that allow us to get rid of the anatop one.
 
 Drivers are also gradually getting Device Tree and IRQ domain support.
 
 The following drivers got DT support:
 - palmas, 88pm860x, tc3589x and twl4030-audio
 
 And those ones now use the IRQ domain APIs:
 - 88pm860x, tc3589x, db8500_prcmu
 
 Also some other interesting changes:
 - Intel's ICH LPC now supports Lynx Point
 - TI's twl4030-audio added a GPO child
 - tps6527 enabled its backlight subdevice
 - The twl6030 pwm driver moved to the new PWM subsystem
 
 And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas,
 ab8500, wm8994, wm5110, max8907 and the tps65xxx family.
