This add regulator driver for Smartbond DA1469X SOC.
Driver can control VDD, V14, V18, V18P, V30 rails,
full voltage range supported by SOC is covered.
For VDD, V14, V18, V18P DCDC can be configured.
Special VDD_CLAMP (always on) and VDD_SLEPP are added
to allow configuration of VDD in sleep modes.

Add an option to drive inactive columns to inactive state rather than
high impedance. This is useful if the matrix has isolation diodes for
every key, as it allows the matrix to stabilize faster and the API for
changing the pin value is more efficient than the one to change the pin
configuration.

This commit introduces the SOF host DMA driver.
This driver is used by NXP platforms in the context of
SOF's host component to copy data from the host memory
to the firmware (local) memory. This is possible because
NXP platforms can access the host memory directly w/o
an actual DMA engine.

Adds a clock control device for a PWM node, allowing the PWM
to be controlled using the clock control API.
It is a similar idea to the device driver in linux:

Split the common keyboard scanning code out of the ITE specific driver
and use the generic code instead.
Note that this changes few timing defaults, the change is not
significant though so I suspect there's no difference in practice.

Setting slew-rate property is not supported on Kinetis KE series
and the value will not have effect, so this property should not
be required.
We are also planning to reuse the Kinetis pin control binding and
associated driver for NXP S32K1xx devices, which doesn't support
setting the slew-rate rate as well.

This functionality has been moved to the common driver, so it can

The LPS22DF is an ultracompact, piezoresistive, absolute pressure sensor
that functions as a digital output barometer. The LPS22DF provides lower
power consumption, achieving lower pressure noise than its predecessor.
This driver is based on stmemsc HAL i/f v2.3

The icmsg and icmsg_me backends has limitations in context of
concurrent access to single instance. Some limitations are:
* sending by more thread at the same time may cause -EBUSY
* allocating TX buffer will cause errors in other threads that want
to allocate before first thread sent the message,
* during no-copy receive, when RX buffer is on hold receiving is
totally blocked.
This backend resolves those limitations by adding dynamically allocated
buffers on shared memory next to ICmsg circular buffer. The data is
passed using those buffers, so concurrency is not a problem. The ICmsg
is used only to pass short 2-byte messages containing references to
those buffers. The backend also supports multiple endpoint.
The ipc/icmsg_me sample was modified to support this backend.

Move all the generic code from the Nuvoton NPCX keyboard scanning driver
into input_kbd_matrix.c. While doing that convert few configs into
devicetree properties and tweak few other things to enable the generic
code to support multiple instances.
This is limited to 8 rows for now, and that's fine for all the current
in-tree drivers, the limit could be removed down the road but this
should be fine for now, added few generic build checks to make sure a
driver does not go over the limit, as well and some more implementation
specific checks.

Add pinctrl to the Davinci GPIO driver to allow muxing pins dirctly

Also aligned the macro backslashes as line continuation character at

This commit enables clock control on the i.MX8QM and QXP boards.
This is achieved through the following changes:
1) The "reg" property is no longer marked as required
for the "nxp,imx-ccm" binding. This is necessary because
in the case of i.MX8QM and i.MX8QXP the clock management
is done through the SCFW, hence there's no need to access
CCM's MMIO space (not that you could anyways).
2) The DTS now contains a scu_mu node. This node refers
to the MU instance used by the DSP to communicate with
the SCFW.
3) The CCM driver needs to support the LPUART clocks
(which will be the only IP that's supported for now)
and needs to perform an initialization so that the
NXP HAL driver knows which MU to use to communicate
with the SCFW.
