Linus Torvalds b3345d7c57 ARM: SoC platform changes for 3.17
This is the bulk of new SoC enablement and other platform changes for 3.17:
 
 * Samsung S5PV210 has been converted to DT and multiplatform
 * Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
 * Kirkwood, one of the popular Marvell platforms, is folded into the
   mvebu platform code, removing mach-kirkwood.
 * Hwmod data for TI AM43xx and DRA7 platforms.
 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being
   multiplatform/DT-enabled and the other two old platforms being removed.
 
 New platforms (most with only basic support right now):
 
 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced
 
 + as usual a lot other pieces all over the platform code.

Linus Torvalds 44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

Linus Torvalds c67d9ce166 ARM: SoC board support updates for 3.16
The bulk of this branch is updates for Renesas Shmobile. They are still
 doing some enablement for classic boards first, and then come up with DT
 bindings when they've had a chance to learn more about the hardware. Not
 necessarily a bad way to go about it, and they're looking at moving some
 of the temporary board code resulting from it to drivers/staging instead
 to avoid the churn here.
 
 As a result of the shmobile clock cleanups, we end up merging quite a
 bit of SH code here as well. We ended up merging it here instead of in
 the cleanup branch due to the other board changes depending on it.

R-Car H2 has many DMACs
(ex SYS-DMAC, 2D-DMAC, Audio-DMAC, USB-DMAC etc)
and, these DMAEngine needs DMA slave IDs to use it.

This patch adds new DMA slave ID list for r8a7790.
There, common part has RCAR_DMA_xxx prefix,
and Audio DMAC part has AUDIO_DMAC_SLAVE_xxx prefix.

Audio DMAC can be controlled via sh-dma-engine

Linus Torvalds dfd10e7ae6 ARM: SoC platform changes for 3.14
New core SoC-specific changes.
 
 New platforms:
 * Introduction of a vendor, Hisilicon, and one of their SoCs with some
   random numerical product name.
 * Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m, i.e. !MMU).
 * Marvell Berlin series of SoCs, which include the one in Chromecast.
 * MOXA platform support, ARM9-based platform used mostly in industrial products
 * Support for Freescale's i.MX50 SoC.
 
 Other work:
 * Renesas work for new platforms and drivers, and conversion over to
   more multiplatform-friendly device registration schemes.
 * SMP support for Allwinner sunxi platforms.
 * ... plus a bunch of other stuff across various platforms.

Valentine Barshak db455c7868 ARM: shmobile: r8a7790: Fix I2C controller names
This fixes the issue introduced by the following commit:
b448c904f5 "ARM: shmobile: r8a7790: add I2C support"

The R8A7790 is an R-Car Gen2 SoC. The clock division factor
(CDF) width is 3 bits on Gen2 as opposed to 2 bits on Gen1.
Fix the device names for R8A7790 SoC to make the R-Car I2C
driver configure the hardware properly.

Changes in V2:
* rebased on top of the latest branch;
* capitalized ARM in the subject line;
* noted the commit that caused the issue in the log.

Simon Horman 6dace67f9b ARM: shmobile: lager: Add DT reference
This is sufficient to allow boot of the Lager board with
a console without boards-lager.c compiled into the kernel.
This is an example of a minimal but still useful initialisation
of the board using DT as much as possible.

As such it is the same as the boot of Lager that can be achieved
without a board file. The intention of adding this file
is to facilitate further work to allow board specific devices to be
initialised via DT.

Magnus Damm 81b9d5351f ARM: shmobile: Setup r8a7790 arch timer based on MD pins
Update the r8a7790 arch timer setup code to configure the
frequency dynamically at boot time. This means that the arch
timer driver will be able to detect a timer frequency that
has been calculated based on the MD pins instead of a fixed
and potentially incorrect 13 MHz.

With this patch applied the Linux kernel will correctly
support the r8a7790 Lager board that uses a 20 Mhz EXTAL.
The arch timer will operate on 10 MHz and the Linux arch
timer driver will be correctly configured to use 10 MHz.

Without this patch the 20 MHz EXTAL will be used to drive
the arch timer at 10 MHz, but the Linux arch timer driver
will believe it is counting at 13 Mhz.
