From Shawn Guo <shawn.guo@linaro.org>:
The imx fixes for 3.9, take 5:
* A couple imx35 clock fixes for regressions caused by common clock
framework conversion. The admux and iomux get disabled by common
clock framework late initcall, and hence causes problems.
* Add missing twd clock lookup in device tree. This becomes required
since commit bd60345 (ARM: use device tree to get smp_twd clock)
forces all DT boot to find lookup from device tree.
* Fix imx6q ldb_di clock parents mismatch per reference manual.

While booting from device tree, imx6q used to provide twd clock lookup
by calling clk_register_clkdev() in clock driver. However, the commit
bd60345 (ARM: use device tree to get smp_twd clock) forces DT boot to
look up the clock from device tree. It causes the failure below when
twd driver tries to get the clock, and hence kernel has to calibrate the
local timer frequency.
smp_twd: clock not found -2
...
Calibrating local timer... 396.13MHz.
Fix the regression by providing twd clock lookup from device tree, and
remove the unused twd clk_register_clkdev() call from clock driver.

Pull ARM SoC bug fixes from Arnd Bergmann:
"After a quiet set of fixes for 3.9-rc4, a lot of people woke up and
sent urgent fixes for 3.9. I pushed back on a number of them that got
deferred to 3.10, but these are the ones that seemed important.
Regression in 3.9:
- Multiple regressions in OMAP2+ clock cleanup
- SH-Mobile frame buffer bug fix that merged here because of
maintainer MIA
- ux500 prcmu changes broke DT booting
- MMCI duplicated regulator setup on ux500
- New ux500 clock driver broke ethernet on snowball
- Local interrupt driver for mvebu broke ethernet
- MVEBU GPIO driver did not get set up right on Orion DT
- incorrect interrupt number on Orion crypto for DT
Long-standing bugs, including candidates for stable:
- Kirkwood MMC needs to disable invalid card detect pins
- MV SDIO pinmux was wrong on Mirabox
- GoFlex Net board file needs to set NAND chip delay
- MSM timer restart race
- ep93xx early debug code broke in 3.7
- i.MX CPU hotplug race
- Incorrect clock setup for OMAP1 USB
- Workaround for bad clock setup by some old OMAP4 boot loaders

Slow down the I2C clock speed on M28 and SPS1 as it turns out the
I2C block in i.MX28 can not operate stable enough with the bus
running at 400kHz. Note that the driver used by Freescale runs
the bus at 250kHz when 400kHz speed is selected, but the mainline
Linux kernel runs the bus at actual 400kHz and that's where it is
occasionally unstable. Play safe and run the bus at 100kHz.

The previous configuration used the wrong "clk" pin. Without this
change mv_sdio worked because the bootloader would set the pin up, but
with a bootloader that does not set the pin, mv_sdio fails to detect any
card.
I have tested this change using a mwifiex_sdio wireless network adapter
over the SDIO interface.

The crypto functionality in the orion5x dtsi uses the Ethernet IRQ and
so things do not work and there is much grumbling at boot time.
The IRQ for the crypto should be 28, and not 22, and that is what this
patch corrects.

orion5x.dtsi is missing the gpio alias as well as including a typo

This fixes a regression introduced by commit:
05ec260 mfd:db8500-prcmu: update resource passing
All DBx5x0 based SoCs have access to two Tightly Coupled Memory
(TCM) locations based on the PRCMU itself. One area from program
memory (TCPM) and one for data memory (TCDM). The PRCMU needs to
know where these are in order to function correctly. However,
these are currently passed though platform device resources, which
can only be obtained if Device Tree booting isn't in use. Thus we
must also support them in DT by supplying them through the PRCMU
node.

"Things are calming down for arm-soc as well. This set of bug fixes is
dominated in size by the at91 platform bug fixes. Some of them were
meant to go through the framebuffer tree during the merge window, but
since the framebuffer maintainer could not be reached, I offered to
take them here. The other notable at91 change is the addition of
pinctrl definitions to fix the NAND controller.
The rest are mostly simple regression fixes:
- Our removal of VIRT_TO_BUS conflicted with Stephen Rothwell's
renaming of the Kconfig symbol. You will get a trivial merge
conflict here, we still want to remove it.
- missing bits for clocks on imx and s5pv210
- missing header inclusions in mmp and shmobile
- typos in s5pv210 camera and vt8500 clock support code

From Stephen Warren <swarren@wwwdotorg.org>:
ARM: tegra: cleanup
This branch includes various cleanup of the core Tegra support.
* Unification of the separate board-dt-tegra*.c files into a single
tegra.c, now that everything is DT-driven and basically identical.
* Use of_clk_get() in the Tegra clocksource driver so that clocks are
described in DT rather than hard-coding clock names.
* Some cleanup of the PMC-related code, with the aim that the PMC
"driver" contains more of the code that touches PMC registers, rather
than spreading PMC register accesses through other files.
* Conversion of the "PMC" driver to acquire resources describe in device
tree rather than hard-coding them.
* Use of common code for the CPU sleep TLB invalidation.

The ab8500 device is a child of the prcmu device, which is a memory mapped
bus device, whose children are addressable using physical memory addresses,
not using mailboxes, so a mailbox number in the ab8500 node cannot be
parsed by DT. Nothing uses this number, since it was only introduced
as part of the failed attempt to clean up prcmu mailbox handling, and
we can simply remove it.

Setting the reg-io-width to 1 byte represents more accurate
description of the HW.
This will fix an issue where UART driver causes kernel
panic during bootup. Gregory CLEMENT traced the issue to
autoconfig() in 8250.c, where the existence of FIFO is
checked from UART_IIR register. The register is now read as
32-bit value as the reg-io-width is set to 4-bytes. The
retuned value seems to contain bogus data for bits 31:8,
causing the issue.

When DT support for kirkwood was first introduced, there was no clock
infrastructure. As a result, we had to manually pass the
clock-frequency to the driver from the device node.
Unfortunately, on kirkwood, with minimal config or all module configs,
clock-frequency breaks booting because of_serial doesn't consume the
gate_clk when clock-frequency is defined.
The end result on kirkwood is that runit gets gated, and then the boot
fails when the kernel tries to write to the serial port.
Fix the issue by removing the clock-frequency parameter from all
kirkwood dts files.
Booted on dreamplug without earlyprintk and successfully logged in via
ttyS0.

BCM2835-ARM-Peripherals.pdf states that the I2C module's input clock is
nominally 150MHz, and that value is currently reflected in bcm2835.dtsi.
However, practical measurements show that the rate is actually 250MHz,
and this agrees with various downstream kernels.
Switch the I2C clock's frequency to 250MHz so that the generated bus
clock rate is accurate.
