Bartosz Golaszewski 1d272894ec ARM: davinci: omapl138-hawk: add a fixed regulator for ohci-da8xx
Instead of directly using the vbus GPIO we should model it as a fixed
regulator. Add all necessary fix-ups for the regulator to be registered
and configure the vbus GPIO as its enable pin.

We're going to extend the cp_intc_init() function with a config
structure so we can drop the intc-related fields from davinci_soc_info.

Once we do it, we won't be able to use this routine directly as the
init_irq callback. Wrap the calls in additional helpers that don't
take parameters and can be assigned to init_irq.

Linus Torvalds 167569343f ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the
 Nuvoton NPCM is used as a baseboard management controller, competing
 with the better known ASpeed AST2xx series.
 
 Another important change is the addition of ARMv7-A based chips
 in mach-stm32. The older parts in this platform are ARMv7-M based
 microcontrollers, now they are expanding to general-purpose workloads.
 
 The other changes are the usual defconfig updates to enable additional
 drivers, lesser bugfixes. The largest updates as often are the ongoing
 OMAP cleanups, but we also have a number of changes for the older
 PXA and davinci platforms this time.
 
 For the Renesas shmobile/r-car platform, some new infrastructure
 is needed to make the watchdog work correctly.
 
 Supporting Multiprocessing on Allwinner A80 required a significant
 amount of new code, but is not doing anything unexpected.

This is the proper place to init clocks. This is also done in preparation
for moving to the common clock framework.

dm646x is a special case because we need to handle different ref_clk rates
depending on which board is being used. The clock init in this case is
modified to set the rate before registering the clocks instead of using
davinci_set_refclk_rate() to recalculate the entire clock tree after all
of the clocks are registered.

Also, the cpu_clks field is removed from struct davinci_soc_info since it

This converts from using a platform device for the CFGCHIP syscon
regmap to using platform data to pass the regmap to consumers.

A lazy getter function is used so that the regmap will only be
created if it is actually used. This function will also be used
in the clock init when we convert to the common clock framework.

The USB PHY driver is currently the only consumer. This driver is
updated to use platform data to get the CFGCHIP regmap instead of
syscon_regmap_lookup_by_pdevname().

Currently the mmc driver is polling the gpio to know if the

By using a gpio descriptor instead of the platform callbacks,
the driver will be able to register the gpio using the mmc core
APIs designed for this purpose.

This has the advantage that an irq will be registered, and
polling is no longer needed. Also, a dependency on platform
callbacks is removed for this board.

The phy framework requests an optional "phy" regulator. If it does
not find one, it returns -EPROBE_DEFER. In the case of non-DT boot
for the omap138-lcdk board, this would prevent the usb11 phy to probe
correctly and ohci would not enumerate.

By calling regulator_has_full_constraints(), An error would be returned
instead of -EPROBE_DEFER for the regulator, and the probe of the phy driver
can continue normally without a regulator.

Updates of SoC-near drivers and other driver updates that makes more sense to

 - Some Davinci driver updates that has required corresponding platform code
   changes (gpio mostly)
 - CCI bindings and a few driver updates
 - Marvell mvebu patches for PCI MSI support (could have gone through the PCI
   tree for this release, but they were acked by Bjorn for 3.12 so we kept them
   through arm-soc).
 - Marvell dove switch-over to DT-based PCIe configuration
 - Misc updates for Samsung platform dmaengine drivers

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM driver updates from Olof Johansson:
 "Updates of SoC-near drivers and other driver updates that makes more
  sense to take through our tree.  In this case it's involved:

   - Some Davinci driver updates that has required corresponding
     platform code changes (gpio mostly)
   - CCI bindings and a few driver updates
   - Marvell mvebu patches for PCI MSI support (could have gone through
     the PCI tree for this release, but they were acked by Bjorn for
     3.12 so we kept them through arm-soc).
   - Marvell dove switch-over to DT-based PCIe configuration
   - Misc updates for Samsung platform dmaengine drivers"

Linus Torvalds 6c5096e553 arm-soc: board specific changes
These updates are all for board specific code, including
 
 * defconfig updates for shmobile, davinci, bcm2835, imx, omap and tegra
 * SD/MMC and I2C support on bcm2835 (Raspberry PI)
 * minor updates for PXA
 * shmobile updates to GPIO usage in board files
 * More things in OMAP board files are moved over to device tree probing
 * Better support for audio devices on some OMAP platforms
 
 Conflicts include the omap board-apollon.c file that is removed without
 a replacement, and conflicting context in the 4430sdp board file.

Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.
