5990047cef ARM: dts: dra7-evm: Fix NAND GPMC timings
The nand timings were scaled down by 2 to account for
the 2x rate returned by clk_get_rate(gpmc_fclk).

As the clock data got fixed by [1], revert back to actual
timings (i.e. scale them up by 2).

Without this NAND doesn't work on dra7-evm.

7a6540ca85 ARM: mvebu: Change vendor prefix for Intersil Corporation to isil
Currently there is a wild mixture of isl, isil, and intersil
compatibles in the kernel. At this point, changing the vendor
symbol to the most often used variant, which is equal to the
NASDAQ symbol, isil, should not hurt.

500abb6ccb ARM: mvebu: Netgear RN2120: Use Hardware BCH ECC
The bootloader on the Netgear ReadyNAS RN2120 uses Hardware BCH
ECC (strength = 4), while the pxa3xx NAND driver by default uses
Hamming ECC (strength = 1).

This patch changes the ECC mode on these machines to match that
of the bootloader and of the stock firmware. That way, it is
now possible to update the kernel from userland (e.g. using
standard tools from mtd-utils package); u-boot will happily
load and boot it.

The issue was initially reported and fixed by Ben Pedell for
RN102. The RN2120 shares the same Hynix H27U1G8F2BTR NAND
flash and setup. This patch is based on Ben's fix for RN102.

e2265abe7a ARM: dts: OMAP5 / DRA7: switch over to interrupts-extended property for UART
We've had deeper idle states working on omaps for few years now,
but only in the legacy mode. When booted with device tree, the
wake-up events did not have a chance to work until commit
3e6cee1786 ("pinctrl: single: Add support for wake-up interrupts")
that recently got merged. In addition to that we also needed
commit 79d9701559 ("of/irq: create interrupts-extended property")
that's now also merged.

Note that there's no longer need to specify the wake-up bit in
the pinctrl settings, the request_irq on the wake-up pin takes
care of that.

1f53170b80 ARM: dts: Add SPI nodes to rk3288
This adds basic SPI nodes to the base rk3288 device tree file.

A few notes:
* It's assumed that most users of the SPI ports are using chip select
  0.  Thus the default pinctrl for the ports enables chip select 0
  (but not chip select 1 on ports that have it).  If a board wants to
  use chip select 1 or wants a GPIO chip select the board should
  override the pinctrl (just like boards can override UART pinctrl if
  they have hardware flow control).
* Since SPI DMA support appears broken and the SPI works fine without
  DMA we don't include the DMA references.  That can come in a later
  change.

84ace6741b ARM: dts: omap5.dtsi: add DSS RFBI node
The RFBI node for OMAP DSS was left out when adding the rest of the DSS
nodes, because it was not clear how to set up the clocks for the RFBI.

However, it seems that if there is a HWMOD for a device, we also need a
DT node for it. Otherwise, at boot, we get:

WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2542 _init+0x464/0x4e0()
omap_hwmod: dss_rfbi: doesn't have mpu register target base

Now that v3.17-rc3 contains a fix 8fd46439e1 ("ARM: dts:
omap54xx-clocks: Fix the l3 and l4 clock rates") for the L3 ICLK
required by the RFBI, let's add the RFBI node to get rid of the
warning.

These baseboards are equipped with the Technexion TAO35030 SOM. So
they include this dtsi. The common parts are extracted into an "common"
dtsi file. The main difference between both boards is, that the *lcd
has DSS support enabled for the LCD.

Some HEAD acoustics specific features are:

- LED handling
- Special FPGA/DSP audio driver (not included in this series)

6dbaff2bfb ARM: tegra: rely on bootloader pinmux programming on Tegra124
The defined mechanism for programming the Tegra pinmux is to perform all
of the following at once in order, before using any I/O controller that
is affected by the pinmux:

- Set the CLAMP_INPUTS_WHEN_TRISTATED PMC register bit.
- Set up any GPIO pins to their "initial" state.
- Program all pinmux settings in one go.

Other methods such as:

- Not setting CLAMP_INPUTS_WHEN_TRISTATED.
- Not setting GPIOs to their "initial" state before programming the
  pinmux settings of the related pin, in particular the mux function.
- Not programming the entire pinmux at once, in order to avoid
  possible conflicting settings.

... are not qualified or supported by NVIDIA ASIC/syseng. They could
cause glitches or undesired output levels on some pins, or controller
malfunction.

While we've been getting away with doing something different on many
Tegra boards without issue, I believe we've just been getting lucky.
I'd like to switch all Tegra124 systems to the correct scheme now so
they provide the right example to follow, and require that any new
boards we support upstream work in the same fashion.

While it would be nice to update boards containing older SoCs for
consistency, I don't anticipate doing so. It's too much churn to change
at this time. At least with all Tegra124 boards converted, the most
recent boards provide the correct example.

Since the bootloader needs to reprogram the pinmux to access certain
peripherals, it must program the entire pinmux due to the supported
rules above. As such, there is no need to program any part of the pinmux
from the kernel, unless dynamic pinmuxing is used. Given this, we couuld
simply remove the pinmux "default" state from the DT entirely. However,
some bootloaders parse the DT to perform their initial pinmux setup, so
it's useful to keep the pinmux data in DT. To allow this while avoiding
redundant work in the kernel, rename the "default" state to "boot". The
kernel won't apply this, but bootloaders can still look for this state
name and apply it. Note however that the DT provides zero information
about the required initial GPIO setup, so bootloaders using this approach
are not likely to operate correctly without an additional GPIO
initialization table somewhere. Previous discussions on the DT mailing
list have rejected adding such a table to DT...

The following U-Boot commits fully initialize the pinmux:

Jetson TK1: 4ff213b8e478 ARM: tegra: clamp inputs on Jetson TK1
Venice2: 3365479ce78a ARM: tegra: Venice2 pinmux spreadsheet updates
Both are part of U-Boot v2014.07 and later.

Without those commits, the only fallout I see from this change is that
HDMI on Venice2 no longer works. Given the very small user-base of this
platform, I feel that requiring a bootloader update is reasonable.

eb481f9ac9 ARM: tegra: add Acer Chromebook 13 device tree
The Acer Chromebook 13, codenamed Big, contains an NVIDIA tegra124
processor and is similar to the Venice2 reference platform.

The keyboard, USB 2, audio, sdcard and emmc have been tested
and work on the 1366x768 models. The Full HD models haven't been
tested yet.

WiFi does not yet work, it needs at least some PMIC changes to enable
the 32k clock.

The elan trackpad is not yet functional but hopefully will be soon as
there are patches under review.

There is also an issue on reboot because the TPM isn't reset.  It will
cause the stock firmware to enter recovery mode.  This can be worked
around by an EC-reset, press the refresh and power keys at the same
time.
