The registration of the fixed clocks uses the node name as the clock
name, causing a clash if two clock nodes have the same name, regardless
of the path to the node. Fix the issue by overwriting the clock node
names using the value of the "addr" parameter, providing a crude
disambiguation. (A bit of string pasting to form "sc16is752_clk_<addr>"
would have been nice, but that is outside the abilities of the overlay
parameter mechanism.)
Also give the sc16is750-i2c overlay the xtal parameter for symmetry.

A backward compatible update for the balenaFin carrier board for the
Raspberry Pi Compute Module 3/3+ Lite.
The updated overlay includes:
* support for the newly introduced RGB LEDs
* i2c-gpio and SDIO improvements
* DT based Marvell 88W8887 configuration

The firmware has support for updating overrides with the correct
GPIO settings for the camera GPIOs, but the wrong device tree
setup ended up being merged.
Correct the DT configuration so that the firmware does set it
up correctly.

"dtoverlay=sdio,bus_width=1,gpios_22_25" is equivalent to the sdio-1bit
overlay, which is now deprecated.
"dtoverlay=sdio,bus_width=1,gpios_34_37" enables 1-bit mode on GPIOs 34-37.

The compatible string was set to "fepi,sgtl5000", which worked for some
reason in 4.14, but does not work in 4.19, presumably due to some
change in the kernel matching logic. The correct string is
"fsl,sgtl5000".

IR receivers like the TSOP series from Vishay and compatible ones
have active-low open collector outputs with an internal pull up of
about 30k (according to the TSOP datasheets).
Activating a pull-down resistor on the GPIO will make it work against
the pull-up in the IR receiver and brings the idle input voltage down
to about 1.9V (measured on a RPi3B+ with a TSOP4438). While that's
usually enough to make the RPi see a high signal it's certainly not
optimal and may even fail when using an IR receiver with a weaker pull-up.
Switching the default GPIO pull to "up" results in an input voltage
level of about 3.3V and ensures that an idle state (high signal) will
be detected if no IR receiver is attached.

Add "eth_downshift_after" DT parameter to allow the delay before the
downshift to be specified. The default is 2 auto-negotiation cycles,
and legal values are 2, 3, 4, 5 and 0 (disabled).
Add "eth_max_speed" DT parameter as a way of prohibiting 1000Mbps
links. This can be used to avoid the delay until the downshift mechanism
activates. Legal values are 10, 100 and 1000, where the default is
unlimited (effectively 1000Mbps).

The driver that supports the ADV7282-M also supports the ADV7280-M,
ADV7281-M, and ADV7281-MA.
The 7280-M exposes 8 analogue inputs. The 7281-M doesn't have the
I2P deinterlacing block. The 7281-MA has 8 inputs but no I2P.
Otherwise they are the same as ADV7282-M.
Adds a new overlay "adv728x" that includes the existing adv7282
overlay but adds several parameters to modify the behaviour.
Adds a new addr parameter to allow the I2C address to be changed.
(the chip has an address select pin to change between 0x20 and 0x21).

DT overlays to setup the above devices via i2c_arm and csi1.
(This currently does not use the i2c-mux-pinctrl driver to
dynamically switch the pinctrl)
tc358743 is tc358743 running at a default link frequency
of 972Mbit/s. This allows up to 1080P50 UYVY on 2 lanes.
There is a parameter to allow changing the link frequency,
but the only values supported by the driver are 297000000
for 594Mbit/s, and 486000000 for 972Mbit/s.
There is also a parameter to enable 4 lane mode (only
relevant to Compute Module (1 or 3) csi1).
tc358743-audio overlay enables I2S audio from the TC358743
to the Pi (SD to GPIO20, SCK to GPIO18, WFS to GPIO19).
ADV7282M is the Analog Devices analogue video to CSI bridge
chip.

supports VGA 8bit Bayer and very few controls.
