0dd1e247fd drivers: PL011: add support for the ARM SBSA generic UART
The ARM Server Base System Architecture[1] document describes a
generic UART which is a subset of the PL011 UART.
It lacks DMA support, baud rate control and modem status line
control, among other things.
The idea is to move the UART initialization and setup into the
firmware (which does this job today already) and let the kernel just
use the UART for sending and receiving characters.

We use the recent refactoring to build a new struct uart_ops
variable which points to some new functions avoiding access to the
missing registers. We reuse as much existing PL011 code as possible.

In contrast to the PL011 the SBSA UART does not define any AMBA or
PrimeCell relations, so we go with a pretty generic probe function
which only uses platform device functions.
A DT binding is provided with this patch, ACPI support is added in a
separate one.

61e331202f Second set of new driver, functionality and cleanups for IIO in the 4.2 cycle.
Core functionality
 * i and q modifiers from quadrature channels.
 * IIO_CHAN_INFO_OVERSAMPLING_RATIO added.
 * High pass filter attributes added to mirror the existing low pass filter
   ones.
 
 Core cleanups
 * Make IIO tools building more cross compiler friendly.
 * Substantial rework of the function __iio_update_buffers to greatly simplify
   a hideously evolved function.
 
 New drivers and support
 * ACPI0008 ambient light sensor driver. This one has been around a long time to
   will be good to finally get it into mainline.
 * Berlin SOC ADC support.
 * BMC150 magnetometer.  The accelerometer in the same package has been supported
   for quite some time, so good to have this half as well.
 * m62332 DAC driver
 * MEMSIC MMC35420 magnetometer.
 * ROHM BH1710 and similar ambient light sensors.
 * Sensortek STK3310 light sensor.
 * Sensortek STK8312 accelerometer.
 * Sensortek STK8BA50 accelerometer.
 * ti-adc128s052 gains support form the adc122s021 2 channel ADC.
 
 Driver cleanups and functionality.
 * Allow various drivers to compile with !GPIOLIB if COMPILE_TEST enabled.
 * bmc150 - decouple trigger from buffer to allow other triggers to be used.
 * bmg160 - decouple trigger from buffer to allow other triggers to be used.
   Fix a trivial unused field.
 * Constify a load of platform_device_id structures.
 * inv_mpu6050 - device tree bindings.
 * hid-sensors - fix a memory leak during probe if certain errors occur.
 * ltr501 - illuminance channel derived (in an non obvious fashion) from the
   intensity channels.
 * ltr501 - fix a boundary check on the proximity threshold.
 * mlx90614 - drop a pointless return.
 * mma8452 - Debugfs register access and fix a bug that had no effect (by
   coincidence)
 * ti_am335x_adc - add device tree bindings for sample-delay, open-delay and
   averaging.  The ideal settings for these tend to be board design specific.

This driver manages Qualcomm CoreSight Replicator device, which
resides on the AMBA bus. Replicator has been made programmable to
allow software to turn of the replicator branch to sink that is not
being used. This avoids trace traffic to the unused/non-current sink
from causing back pressure that results in overflows at the source.

e465bf6fc5 DT: i2c: Deprecate adi,adxl34x compatible string
DT nodes should use the more specific adi,adxl345 and adi,adxl346
compatible values instead. As the ADXL346 is backward-compatible with
the ADXL345, ADXL346 nodes must list both adi,adxl346 and adi,adxl345,
in that order.

8064887e02 ARM: vf610: enable Cortex-M4 configuration on Vybrid SoC
This patch allows to build the Kernel for Vybrid (VF6xx) SoC
when ARMv7-M CPU is selected. The resulting image runs on the
secondary Cortex-M4 core. This core has equally access to all
peripherals as the main Cortex-A5 core. However, there is no
resource control mechanism, hence when both cores are used
simultaneously, orthogonal device tree's are required.

The boot CPU is dependent on the SoC variant. The available
boards use mostly variants where the Cortex-A5 is the primary
and hence the boot CPU. Booting the secondary Cortex-M4 CPU
needs SoC specific registers written. There is no in kernel
support for this right now, a external userspace utility
called "m4boot" can be used to boot the kernel:

m4boot xipImage initramfs.cpio.lzo vf610m4-colibri.dtb

f936779329 pinctrl: sirf: add sirf atlas7 pinctrl and gpio support
The Pinctrl module (ioc) controls the Pad's function select
(each pad can have 8 functions), Pad's Drive Strength, Pad's
Pull Select and Pad's Input Disable status.

The ioc has two modules, ioc_top & ioc_rtc. Both of these two
modules have function select/clear, Pull select and Drive
Strength registers. But only ioc_rtc has input-disable
registers. The Pads on ioc_top have to access ioc_rtc to set
their input-disable status and intpu-disable-value.

So have to use one ioc driver instance to drive these two
ioc modules at the same time, and each ioc module will be
treat as one bank on the "IOC Device".

The GPIO Controller controls the GPIO status if the Pad has
been config as GPIO by Pinctrl already. Includes the GPIO
Input/output, Interrupt type, Interrupt Status, and Set/Get
Values.
The GPIO pull up/down are controlled by Pinctrl.

There are 7 GPIO Groups and splited into 3 MACROs in atlas7.
The GPIO Groups in one MACRO share one GPIO controllers, each
GPIO Group are treated as one GPIO bank.

For example:
In VDIFM macro, there is one GPIO Controller, it has 3 banks
to control 3 gpio groups. Its gpio name space is from 0 to 95.

The Device Tree can be written as following:

gpio-ranges = <&pinctrl 0 0 0>,
<&pinctrl 32 0 0>,
<&pinctrl 64 0 0>;

gpio-ranges-group-names = "gnss_gpio_grp",
"lcd_vip_gpio_grp",
"sdio_i2s_gpio_grp";

bank#0 is from 0~31, the pins are from pinctrl's "gnss_gpio_grp".
bank#2 is from 32~63, the pins are from pinctrl's "lcd_vip_gpio_grp".
bank#3 is from 64~95, the pins are from pinctrl's "sdio_i2s_gpio_grp".
