Sergei Shtylyov 5d5a87a5b6 ARM: shmobile: Lager: set proper DMA masks for Ether device
Ether MAC is a DMA-capable device and so should have 'dev.dma_mask' and
'dev.coherent_dma_mask' fields set properly, to reflect 32-bit DMA addressing
ability.

Currently, the code works without DMA masks but as we would have to enable
CONFIG_HIGHMEM to access the full board memory in the future, when support for
NETIF_F_SG would be added to the 'sh_eth' driver as well, the correct DMA masks
should start to matter...

Add Lager board code to check the PWEN GPIO signal and refuse to

For correct operation Lager DIP switches SW5 and SW6 shall be
configured in 2-3 position to enable USB Function support.

If the DIP switch is configured incorrectly then the user can
simply adjust the hardware and either reboot or use the bind interface
to try to probe again:

Remove ifdefs to make the Lager USBHS device always present.
This makes it more like other devices, no need to be special.

Also, these ifdefs by themselves do not hurt much, but combined
with USB Host device ifdefs that were proposed earlier we could
basically end up with a kernel that drives VBUS incorrectly
depending on the kernel configuration - lets not do that.

Linus Torvalds d5aabbcaee ARM: SoC board updates for 3.13
Board-related updates. This branch is getting smaller and smaller, which is
 the whole idea so that's reassuring.
 
 Right now by far most of the code is related to shmobile updates, and
 they are now switching over to removal of board code and migration to
 multiplatform, so we'll see their board code base shrink in the near
 future too, I hope.
 
 In addition to that is some defconfig updates, some display updates for OMAP
 and a bit of new board support for Rockchip boards.

 "Board-related updates.  This branch is getting smaller and smaller,
  which is the whole idea so that's reassuring.

  Right now by far most of the code is related to shmobile updates, and
  they are now switching over to removal of board code and migration to
  multiplatform, so we'll see their board code base shrink in the near
  future too, I hope.

  In addition to that is some defconfig updates, some display updates
  for OMAP and a bit of new board support for Rockchip boards"

Linus Torvalds aac59e3efc ARM: SoC platform changes for 3.13
New and updated SoC support. Among the things new for this release are:
 
 - More support for the AM33xx platforms from TI
 - Tegra 124 support, and some updates to older tegra families as well
 - imx cleanups and updates across the board
 - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,
   and turned out to be too broad a name. New name is ARCH_BCM_MOBILE.
 - A whole bunch of updates and fixes for integrator, making the platform code
   more modern and switches over to DT-only booting.
 - Support for two new Renesas shmobile chipsets. Next up for them is more work
   on consolidation instead of introduction of new non-multiplatform SoCs, we're
   all looking forward to that!
 - Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

Sergei Shtylyov 48c8b96f21 ARM: shmobile: Lager: add Micrel KSZ8041 PHY fixup
Currently on the Lager board NFS timeouts/delays are seen when booting.  That
turned out to happen because the SoC's ETH_LINK signal turns on and off after
each packet.  It is connected to Micrel KSZ8041 PHY's LED0 signal. Ether LEDs
on the Lager board are named LINK and ACTIVE which corresponds to non-default
01 setting of the PHY control register 1 bits 14-15. The 'sh_eth' driver resets
the PHY when opening the network device, so we have to set the mentioned bits
back to 01 from the default 00 value which causes bouncing of ETH_LINK.  That
can be achieved using the PHY platform fixup mechanism if we also modify the
driver to use it..

Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches,
 but most of this is around legacy code and board support. We've found that
 platform maintainers have a hard time separating all of these out and might
 move towards fewer branches for next release.
 
 - Removal of a number of Marvell Kirkwood board files, since contents
   is now common and mostly configured via DT.
 - Device-tree updates for Marvell Dove, including irqchip and clocksource
   setup.
 - Defconfig updates. Gotta go somewhere. One new one for Renesas Lager.
 - New backlight drivers for backlights used on Renesas shmobile platforms.
 - Removal of Renesas leds driver.
 - Shuffling of some of the new Broadcom platforms to give room for others in
   the same mach directory. More in 2.13.

  DT branches, but most of this is around legacy code and board support.
  We've found that platform maintainers have a hard time separating all
  of these out and might move towards fewer branches for next release.

   - Removal of a number of Marvell Kirkwood board files, since contents
     is now common and mostly configured via DT.
   - Device-tree updates for Marvell Dove, including irqchip and
     clocksource setup.
   - Defconfig updates.  Gotta go somewhere.  One new one for Renesas
     Lager.
   - New backlight drivers for backlights used on Renesas shmobile
     platforms.
   - Removal of Renesas leds driver.
   - Shuffling of some of the new Broadcom platforms to give room for
     others in the same mach directory.  More in 3.13"

Simon Horman a601469386 ARM: shmobile: lager: do not annotate gpio_buttons as __initdata
When the gpio-keys device is registered using
platform_device_register_data() the platform data argument,
lager_keys_pdata is duplicated and thus should be marked as __initdata
to avoid wasting memory. However, this is not true of gpio_buttons,
a reference to it rather than its value is duplicated when lager_keys_pdata
is duplicated.

This avoids accessing freed memory if gpio-key events occur
after unused kernel memory is freed late in the kernel's boot.

This but was added when support for gpio-keys was added to lager
in c3842e4fcb
("ARM: shmobile: lager: support GPIO switches") which was included
in v3.11-rc1.
