The Hardkernel's Odroid XU board was first design with big.LITTLE SoC
from Samsung: the Exynos5410. Details:
1. Exynos5410 octa-core (A15+A7, however as of now only one cluster is
enabled),
2. 2 GB DDR3 RAM,
3. PowerVR SGX544MP3 GPU (not enabled in DTS),
4. USB 3.0 Host x 1, USB 3.0 OTG x 1, USB 2.0 Host x 4,
5. HDMI 1.4a, MIPI DSI and Display Port (Display Port not on all of
revisions though),
6. eMMC 4.5 and microSD slots.
Comparing this board to Odroid XU3 (more popular), the differences are:
1. Exynos5410 instead of 5422,
2. MIPI DSI LCD connector,
3. Main PMIC: Maxim 77802 instead of S2MPS11,
4. USB3503+LAN9730 instead of integrated LAN9514,
5. eMMC 4.5 instead of eMMC 5.0,
This patch adds initial support for the XU board with working basic
functions, eMMC/SD and USB (including attached ethernet adapter).

This patch adds the Device Tree source for Samsung ARTIK5 module[1]
based on Exynos3250 SoC. The ARTIK5 module includes the following
devices:
- Application Processor (Samsung Exynos3250)
- WiFi/BT Combo chip (Broadcom4354)
- PMIC (Samsung S2MPS14)
- eMMC (4GB)
- DRAM LPDDR3 (512MB)
- Connectors pin (60 Pins x 3 set)
Also, this patch adds the ARTIK5 evaluation board[2] dts file which includes
the ARTIK5 module[1] and have the devices such as sound codec, sd card port,
ethernet port, uart port and so on.

This adds support for the touchscreen on Samsung s3c64xx.
The driver is completely untested but shows roughly how
it could be done, following the example of the at91 driver.
compared to the old plat-samsung/adc driver, there is
no support for prioritizing ts over other clients, nor
for oversampling. From my reading of the code, the
priorities didn't actually have any effect at all, but
the oversampling might be needed.
Verifying this driver is the main issue that is currently
holding up multiplatform support for s3c64xx, so any help
in testing is very much appreciated.
The current version uses the IS_REACHABLE() that is
going to be introduced in the linux-media tree, please
comment this out for testing.

As usual, this is the massive branch we have for each release. Lots of
various updates and additions of hardware descriptions on existing hardware,
as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and 32-bit
DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to tell
from the diffstat, so there's little point in duplicating listing it here.)

The ADC on exynos7 is quite similar to ADCv2. The differences are as
follows:
- exynos7-adc has 8 input channels (as against 10 in ADCv2).
- exynos7 does not include an ADC PHY control register.
- Some ADC_CON2 register bits being used in ADCv2 are listed as
reserved in exynos7-adc. This results in a different init_hw
function for exynos7.

Unlike the board branch, this keeps having large sets of changes for
every release, but that's quite expected and is so far working well.
Most of this is plumbing for various device bindings and new platforms,
but there's also a bit of cleanup and code removal for things that
are moved from platform code to DT contents (some OMAP clock code in
particular).
There's also a pinctrl driver for tegra here (appropriately acked),
that's introduced this way to make it more bisectable.
I'm happy to say that there were no conflicts at all with this branch
this release, which means that changes are flowing through our tree as
expected instead of merged through driver maintainers (or at least not
done with conflicts).
There are several new boards added, and a couple of SoCs. In no particular
order:
* Rockchip RK3288 SoC support, including DTS for a dev board that they
have seeded with some community developers.
* Better support for Hardkernel Exynos4-based ODROID boards.
* CCF conversions (and dtsi contents) for several Renesas platforms.
* Gumstix Pepper (TI AM335x) board support
* TI eval board support for AM437x
* Allwinner A23 SoC, very similar to existing ones which mostly has

Murata Manufacturing Co., Ltd is the vendor for
NTC (Negative Temperature coefficient) based Thermistors.
But, the driver extensively uses "NTC" as the vendor name.
This patch corrects the vendor name also updates the
compatibility strings according to the vendor-prefix.txt
Note: Drivers continue to support the previous compatible strings
but further addition of these compatible strings in device tree
is deprecated.

These are mostly new device tree bindings for existing drivers, as well
as changes to the device tree source files to add support for those
devices, and a couple of new boards, most notably Samsung's Exynos5
based Chromebook.
The changes depend on earlier platform specific updates and touch
the usual platforms: omap, exynos, tegra, mxs, mvebu and davinci.

This patch adds device tree node for the SYSREG registers block
found in Samsung S5P/Exynos SoC series. The SYSREG module
generates control signals for the ARM CPU and various IP blocks
and buses. SYSREG block registers are exposed through APB bus
interface. A sysreg device tree node is to be associated with
mfd syscon driver and all SYSREG clients should use regmap
interface it provides. It allows to eliminate any possible races
and conflicts should different drivers attempt to concurrently
access same register.
