(4 in operation), 4GB ram (3.5 usable) ARM machine.
Support covers device drivers for:
- Serial Peripheral Interface (SPI)
- Chrome Embedded Controller (EC) - SPI-based version
- XHCI and USB 3.0 dual-role device PHY
Also:
- Add support for Exynos5420 in Pad module
- Move power-related functions to separate driver --
Power Management Unit (PMU)
- Enable XHCI for Chromebook1

that it can connect to switches at speeds other than 1gb.
This requires changing the reference clock speed. Since we still don't
have a general clock API that lets a SoC-independant driver manipulate its
own clocks, this change includes a weak reference to a routine named
cgem_set_ref_clk(). The default implementation is a no-op; SoC-specific
code can provide an implementation that actually changes the speed.

(7-bit device address << 1), always leaving the room for the read/write bit.
This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them
compatible with 8-bit addresses. Previous to this commit an i2c device
would have different addresses depending on the controller it was attached
to (by example, when compared to any iicbb(4) based i2c controller), which
was a pretty annoying behavior.
Also, update the PMIC i2c address on beaglebone* DTS files to match the new
address scheme.
Now the userland utilities need to do the correct slave address shifting
(but it is going to work with any i2c controller on the system).

current RADXA config. Radxa Rock (RR) boards have few types such as
RR (full version), RR Lite and some variants of RR engineering samples.
Add kernel config and FDT file for RR Lite board.

- Update FDT file for BERI DE4 boards.
- Add needed kernel configuration keywords.
- Rename module to saf1761otg so that the device unit number does not
interfere with the hardware ID in dmesg.

Adjust the exynos and zedboard dts files to use max-frequency (the
documented standard property) instead of clock-frequency.

NetFPGA-10G Embedded CPU Ethernet Core.
The current version operates on a simple PIO based interface connected
to a NetFPGA-10G port.
To avoid confusion: this driver operates on a CPU running on the FPGA,
e.g. BERI/mips, and is not suited for the PCI host interface.

- Don't allow high-speed mode on OMAP4 due to hardware erratum.
- Check the proper bit in the status register when waiting for the
controller to come out of reset.
- Add handling for the "non-removable" fdt property by always returning
"card is present" status.
- Add the non-removable property for the MMC card on a Beaglebone Black.
- Add the non-removable property for Pandaboard as a workaround.
For Pandaboard the card detect pin is handled by the twl6030 fpga device
which gets an interrupt on pin change and then has to query the fpga
for the actual status. We don't have code to do that yet.

We don't know our ARM security state, so one of them will operate.
- Don't set frequency, since it's unpossible in non-secure state.
Only rely on DTS clock-frequency value or get clock from timer.

Support covers device drivers for:
- Interrupt Combiner
- gpio/pad, External Interrupts Controller (pad)
- I2C Interface
- Chrome Embedded Controller
- Chrome Keyboard
Also:
- Use new gpio dev class in EHCI driver
- Expand device tree information
The ADC has a 12bit resolution and its raw output can be read via sysctl(8)
interface.
The driver allows the setup of ADC clock, samples average and open delay
(the number of clock cycles to wait before start the conversion).
The TSC_ADC module is set in the general purpose mode (no touchscreen
support).
Tested on Beaglebone-black.
Written based on AM335x TRM.
