Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

* NXP LPC1850 UART
|
|
|
|
Required properties:
|
|
- compatible : "nxp,lpc1850-uart", "ns16550a".
|
|
- reg : offset and length of the register set for the device.
|
|
- interrupts : should contain uart interrupt.
|
|
- clocks : phandle to the input clocks.
|
|
- clock-names : required elements: "uartclk", "reg".
|
|
|
|
Optional properties:
|
|
- dmas : Two or more DMA channel specifiers following the
|
|
convention outlined in bindings/dma/dma.txt
|
|
- dma-names : Names for the dma channels, if present. There must
|
|
be at least one channel named "tx" for transmit
|
|
and named "rx" for receive.
|
|
|
|
Since it's also possible to also use the of_serial.c driver all
|
|
parameters from 8250.txt also apply but are optional.
|
|
|
|
Example:
|
|
uart0: serial@40081000 {
|
|
compatible = "nxp,lpc1850-uart", "ns16550a";
|
|
reg = <0x40081000 0x1000>;
|
|
reg-shift = <2>;
|
|
interrupts = <24>;
|
|
clocks = <&ccu2 CLK_APB0_UART0>, <&ccu1 CLK_CPU_UART0>;
|
|
clock-names = "uartclk", "reg";
|
|
};
