DMA engine of some old SDIO host controllers require block size alignment for
data length of each scatterlist item. This patch introduces an intermediate
buffer list to support this kind of platform. It decreases the throughput
because of an extra memcpy in critical data path. So don't turn this on unless
it's necessary.

GMT G762/763 fan speed PWM controller is connected directly to a fan
and performs closed-loop or open-loop control of the fan speed. Two
modes - PWM or DC - are supported by the chip. Introduced driver
provides various knobs to control the operations of the chip (via
sysfs interface). Specific characteristics of the system can be passed
either using board init code or via DT. Documentation for both the
driver and DT bindings are also provided.

EDMA supports a cross bar which provides ability
to mux additional events into physical channels
present in the channel controller.
This is required when the number of events present
in the system are more than number of available
physical channels.
Changes by Joel:
* Split EDMA xbar support out of original EDMA DT parsing patch
to keep it easier for review.
* Rewrite shift and offset calculation.

The Timer Pulse Unit (TPU) is a 4-channels 16-bit timer used to generate
waveforms. This driver exposes PWM functions through the PWM API for
other drivers to use.
The code is loosely based on the leds-renesas-tpu driver by Magnus Damm

The different generations of OMAP2+ SoCs have almost the same
mailbox IP, but the IP has configurable parameters for number
of users (interrupts it can generate out towards processors)
and number of fifos (the base unidirectional h/w communication
channel). This data cannot be read from any registers, and so
has been added to the platform data.
This data together with the interrupt-type configuration can be
used in properly figuring out the number of registers to save
and restore in the OMAP mailbox driver code.

The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY
has extra register range containing two high-speed signal quality characteristic
control registers which should be set up during USB-PHY startup depending on
whether a ferrite bead is in use or not. So, we now handle an optional second
memory range in the driver's probe method, add the 'ferrite_bead' field to the
driver's platform data, and add an extra (optional) step to the USB-PHY startup
routine which sets up the extended registers.
Also mark in the driver's Kconfig section that R8A7778 is now supported and
generally clarify that section, uppercasing the word "phy" and also changing
the module name that got lost in the big driver rename, while at it...
The patch has been tested on the Marzen and BOCK-W boards.

Pins are numbered in the R-Car family documentation using a bank number

we need to flatten this by multiplying the bank number by 32 and adding

relationship to the documentation, making it error-prone.

At this moment in time the memcpy channels which can be used by the D40
are fixed, as each supported platform in Mainline uses the same ones.
However, platforms do exist which don't follow this convention, so
these will need to be tailored. Fortunately, these platforms will be DT
only, so this change has very little impact on platform data.

When a DMA client requests and configures a DMA channel, it requests
data_width in Bytes. The DMA40 driver then swiftly converts it over to
the necessary register bit value. Unfortunately, for any subsequent
calculations we have to shift '1' by the bit pattern (1 << data_width)
times to make any sense of it.
This patch flips the semantics on its head and only converts the value
to its respective register bit pattern when writing to registers. This
way we can use the true data_width (in Bytes) value.

This patch is to disable the USB ports unconnected to USB3503. In order to
disable the port, 'port_off_mask' must be set.
* Disable PORT1 only
.port_off_mask = USB3503_OFF_PORT1;
* Disable PORT1 and PORT3 only
.port_off_mask = USB3503_OFF_PORT1 | USB3503_OFF_PORT3;
* Enables all ports
.port_off_mask = 0;

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/drivers
From Linus Walleij:
This is a set of patches from Lee Jones to start converting
the ux500 to fetch DMA channels from the device tree:
- Full DT support and channel mapping in the DMA40 driver
- Dropping of platform data for migrated devices on the DT
boot path.

This patch adds a ASoC CODEC driver for the SSM2516. The SSM2516 is a stereo
Class-D audio amplifier with an I2S interface for audio in and a built-in
dynamic range control processor.

'struct stedma40_half_channel_info's header comment says that it's
called 'struct stedma40_chan_cfg'. Let's straighten that out.

DMA addresses are now passed as part of the dmaengine API by invoking
dmaengine_slave_config(). So there's no requirement for the DMA40
driver to look them up in a table provided by platform data. This
method does not fit in well using Device Tree either.

This change will cost ~25KB of memory, but it's worth the trade-off,
as it removes a great deal of overhead. It means that instead of only
allocating memory for the logical channels in use, it does so for all
available ones, which is 32 per physical channel. However, this now
means we can remove some platform data and we don't have to worry
about adding vendor specific variables to Device Tree.

Devices which utilise DMA use the same device numbers for transmitting
and receiving. In this patch we encode the source and destination
information into one single attribute. We can subsequently exploit the
direction attribute to see which of the transfer directions are being
described. This also lessens the burden on platform data.

There are only two default memcpy configurations used for the DMA40
driver; one for physical memcpy and one for logical memcpy. Instead
of invariably passing the same configurations though platform data,
we're moving them into the driver instead.
