Set fan max speed to kick in at 65*C. This keeps the unit roughly
at 70*C or lower, when pusing all cores for an extended period of
time.

Fan, RTC and USB support
RTC requires rtc pcf85063 driver
Fan requires hwmon emc2305 driver
Added wakeup-source to fanctrl node so emc2305 module loads at boot.

hwmon: emc2305: fixups for driver
The driver had a number of issues, checkpatch warnings/errors,
and other limitations, so fix these up to make it usable.
hwmon: emc2305: Change OF properties pwm-min & pwm-max to u8
hwmon: emc2305: Add calls to initialize cooling maps

BPI-CM4: Add support for the waveshare cm4-io-base-b

BPI-CM4: Enable usb support on waveshare baseboards via overlay
BPI-SM1: Removed UART_B overlay. Short of it being an available
option in the vendor kernel via overlay. I can not find any docs
to support why that is. I feel it is safer that we just remove it.
BPI-SM1: Add UART_A "pin-ctrl: cts rts"

* dts: amlogic: meson-g12b-bananapi-cm4: switch to enable-gpios
The recommended name for enable GPIOs property in regulator-gpio is
enable-gpios. This is also required by bindings:
meson-g12b-bananapi-cm4-cm4io.dtb: regulator-vddio-c: Unevaluated properties are not allowed ('enable-gpio' was unexpected)

Apparently the builder did care for the original.

Backport DTS/DTSI changes from linux-6.4.y to 6.1.y
Add meson64-reboot driver to all boards
Add board: ODROID N2L
Add uart_A uart_AO_B uart_B uart_C where appropriate
U-Boot v2023.07.02: ODROID N2/N2L/N2Plus/C4
Meson64-reboot driver: (source: tobetter)
While the current meson64-reboot driver is cleaner and doesn't
depend on modding other kernel sources, its functionality leaves
much to be desired. One example can be found in the ODROID C4.
Using the current driver, the board will not properly power off,
leaving the POWER LED still on. The new driver powers off the unit
completely.
Fan control: (ODROID N2L/N2PLus)
Added service and script for controlling the trip point.
fanctrl: arguments: 65 55 45 35 25 menu run

BPI-CM4:
In accordance with the BSP DTS, set LED gpio to GPIO_ACTIVE_LOW.
Added default-on trigger to led-green
Board now powers off, added reboot node 'meson64-reboot'.
CONFIG_POWER_RESET_MESON64
Isolated RESET ODROID driver and renamed to MESON64 as it can be used in more than ODROIDS.
MESON UART
Series improves support for UART attached Bluetooth modules on Amlogic Meson G12A and newer SoCs. These SoCs also support the "divide XTAL by 2" bit which (greatly) reduces jitter when generating baud rates such as 1500000 (which is used by the Bluetooth part of the RTL8822CS SDIO WiFi and UART Bluetooth combo chip).
