a2e99a71b2 w1: Add driver for i.MX bus master controller
Two variants of controllers are supported:
V1 (bitwise only) found in
	i.MX21, i.MX27, i.MX31, i.MX51
V2 (byte operations) found in
	i.MX25, i.MX35, i.MX50, i.MX53

Only tested on i.MX53 hardware but in both modes
(by modifying the device tree).

dfb0a70a1a power: add FAN53555 family support
This adds a driver for the FAN53555 family of regulators and wraps it
in a PMIC implementation.

While these devices support a 'normal' and 'suspend' mode (controlled
via an external pin) to switch between two programmable voltages, this
incarnation of the driver assumes that the device is always operating
in 'normal' mode.

Only setting/reading the programmed voltage is supported at this time
and the following device functionality remains unsupported:
  - switching the selected voltage (via a GPIO)
  - disabling the voltage output via software-control
This matches the functionality of the Linux driver.

Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from
the U-Boot shell and verifying output voltages on the board.

ebb73de168 bootcount: add uclass for bootcount
The original bootcount methods do not provide an interface to DM and
rely on a static configuration for I2C devices (e.g. bus, chip-addr,
etc. are configured through defines statically).  On a modern system
that exposes multiple devices in a DTS-configurable way, this is less
than optimal and a interface to DM-based devices will be desirable.

This adds a simple driver that is DM-aware and configurable via DTS.
If ambiguous (i.e. multiple bootcount-devices are present) the
/chosen/u-boot,bootcount-device property can be used to select one
bootcount device.

Initially, this provides support for the following DM devices:
 * RTC devices

fba725f410 net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driver
This patch adds support for enabling or disabling the lane swapping
(called "port mirroring" in PHY's CFG4 register) feature of the DP83867
TI's PHY device.

One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).

32466c445c doc: bindings: soft-spi: update documentation to match the code
Linux bindings have been introduced in the code (removing the U-Boot
specific ones) without documentation update. Compatible string has
changed, as well as the four GPIO properties. Reflect this by updating
the soft-spi.txt documentation.

Fixes: 102412c415 ("dm: spi: soft_spi: switch to use linux compatible string")

bf802f5d54 power: extend prefix match to regulator-name property
This patch extends pmic_bind_children prefix matching. In addition to
the node name the property regulator-name is used while trying to match
prefixes. This allows assigning different drivers to regulator nodes
named regulator@1 and regulator@10 for example.
I have discarded the idea of using other properties then regulator-name
as I do not see any benefit in using property compatible or even
regulator-compatible. Of course I am open to change this if there are
good reasons to do so.

e80dac0ab8 ARC: clk: introduce HSDK CGU clock driver
Synopsys HSDK clock controller generates and supplies clocks to various
controllers and peripherals within the SoC.

Each clock has assigned identifier and client device tree nodes can use
this identifier to specify the clock which they consume. All available
clocks are defined as preprocessor macros in the
dt-bindings/clock/snps,hsdk-cgu.h header and can be used in device
tree sources.
