In aic3x class of devices Output Common-Mode Voltage can be configured for
better analog performance.
The OCMV value depends on the Analog and digital domain power supply
voltage configuration.
The default OCMV of 1.35V gives best performance when AVDD is around 2.7V
and DVDD is 1.525V, but for higher AVDD/DVDD higher OCMV setting is
recommended.
The patch gives an automatic way of guessing the best OCMV which can be
overwritten by a DT parameter if needed.

In some scenarios, we should set some pins as input/output/pullup/pulldown
when the specified system goes into deep sleep mode, then when the system
goes into deep sleep mode, these pins will be set automatically by hardware.
That means some pins are not controlled by any specific driver in the OS, but
need to be controlled when entering sleep mode. Thus we introduce one sleep
state config into pinconf-generic for users to configure.

HSDK board manages its clocks using various PLLs. These PLL have same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.
Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.
We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.
As of today we add support for PLLs that generate clock for the
HSDK arc cpus, system, ddr, AXI tunnel and hdmi.
By this patch we add support for several plls (arc cpus pll and others),
so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll
and regular probing for others plls.

This VAS module is essentially a library for other device drivers

In the future this will be extended to add support for user space
to access the NX coprocessors.
VAS is currently only supported with 64K page size.

This driver provides PS/2 serio bus support by implementing bit banging
with the GPIO API. The GPIO pins, data and clock, can be configured with
a node in the device tree or by generic device properties (GDP).
Writing to a device is supported as well, though it is possible timings
can not be halt as they are tough and difficult to reach with bit banging.
Therefore it can be configured (also in DT and GDP) whether the serio
write function should be available for clients.
This driver is for development purposes and not recommended for productive
use. However, this driver can be useful e.g. when no USB port is available
or using old peripherals is desired as PS/2 controller chips getting rare.
This driver was tested on bcm2825 and on Kirin 960 and it worked well
together with the atkbd and psmouse driver.

The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
Document in the Device Tree binding document that this manufacturer should
be used as the generic fallback. Also document the deprecated vendors.
