Also create generic overrides in camera-mux-N-port, that can be extended
to configure vsync modes for cameras supporting this.
Example usages (to be combined with camera_auto_detect=0):
dtoverlay=imx477,cam0,sync-source
dtoverlay=imx477,sync-sink
dtoverlay=camera-mux-2port,cam1-imx477,cam1-sync-sink
dtoverlay=camera-mux-4port,cam3-imx477,cam3-sync-sink

Add a 'base' parameter to set an explicit bus number for the channels,

The driver has been converted to use gpiod, which will normalise
polarity based on DT.
The piscreen overlay (and others) incorrectly defines the pendown
GPIO as being ACTIVE_HIGH (0), althought triggering on the high-low
edge for pen down. It therefore tries reading the pen position when
not being touched, and stops when it is touched.
Tested with piscreen and ads7846 overlays. Also fixed on others
where the interrupt says high->low but the polarity was ACTIVE_HIGH.

When running multiple muxes, in order to be able to reuse the
same address on child buses of different muxes you have to
disconnect the mux after every transaction.
Add an override to select that option.

With the RP1 PWM configured to use the 50MHz oscillator clock source,
requesting a 100MHz clock will fail. Set the RP1 PWM clock rate to
50MHz, do the same to other Pi PWM blocks, and remove the default
clock override in the PWM overlays. However, an explicit
"clock=..." parameter is still supported.

GPCLKs have two parts - a clock divider and a clock input, routed out to
and in from a GPIO pad respectively. It follows that the clksrc_gpN
inputs can't be used unless the pad is also configured as a GPCLK, so
leave them disabled.

Dedicated overlay claiming all 4 data lanes of the designware
I2S0 module to drive 4x PCM5102. THe devices share BCLK and
LRCLK, therefore all outputs will always run at the same
samplerate and format.

Whilst the fbtft driver uses the DT property "rotate" to set the display
rotation, the tinydrm ili9486 driver uses "rotation". The overlay was
only updating "rotate" from the override, so add in "rotation".

adding descriptions for both in README
adding changes to Makefile to include both DT's

The CM5 is a platform that will appear in multiple boards, each of
which may have different connectivity. Split the CM5 DTS into a common
cm5.dtsi and board-specific dts files, where the CM5 DTS file (the one
loaded by the firmware by default) is an alias for the CM5IO DTS file.

Expose the invert and swap touch parameters on 2.8" and 3.5" resistive touchscreens. Add
the DRM parameter to the PiTFT 2.2" and 2.8" Capacitive overlay in the same
way it is on the resistive overlays. Change the DRM driver to `adafruit,yx240qv29`
because the rotations are consistent with the FBTFT Driver. Fix the override size parameters
on the 2.8" capacitive PiTFT.

Failing to set a reasonable SDA hold time can cause SDA to change too
close to the falling edge of SCL. 300ns is the recommended minimum
interval between the two at 100kHz and 400kHz, and also seems to
work at 1MHz, so use that.

For the RV3028 RTC, the definitions for its `backup-switchover-mode` overlay
were not intelligible neither complete/exhaustive.
Accordingly to the https://github.com/raspberrypi/linux/issues/2912#issuecomment-477670051
these one here proposed should be correct.
`/boot/config.txt` should be as a configuration example, for rv3028, on a
Uputronics GPS Extension HAT:
# For GPS Expansion Board from Uputronics
dtparam=i2c_arm=on
dtoverlay=i2c-rtc,rv3028,backup-switchover-mode=3
dtoverlay=pps-gpio,gpiopin=18
init_uart_baud=115200
From my tests (`sudo rmmod rtc_rv3028 && sudo i2cget -y 1 0x52 0x37`):
`Default from factory`: `0x10`
`Mode 0`: `0x10`
`Mode 1`: `0x14`
`Mode 2`: `0x18`
`Mode 3`: `0x1c`
`Mode 3`: `0x1c` is consistent with the manufacturer configuration script: http://store.uputronics.com/files/configure-rv3028.sh
