- compatible:
- "marvell,armada-3700-uart" for the standard variant of the UART
(32 bytes FIFO, no DMA, level interrupts, 8-bit access to the
- FIFO, baudrate limited to 230400).
+ FIFO), called also UART1.
- "marvell,armada-3700-uart-ext" for the extended variant of the
UART (128 bytes FIFO, DMA, front interrupts, 8-bit or 32-bit
- accesses to the FIFO, baudrate unlimited by the dividers).
+ accesses to the FIFO), called also UART2.
- reg: offset and length of the register set for the device.
- clocks: UART reference clock used to derive the baudrate. If no clock
is provided (possible only with the "marvell,armada-3700-uart"
Example:
uart0: serial@12000 {
compatible = "marvell,armada-3700-uart";
- reg = <0x12000 0x200>;
+ reg = <0x12000 0x18>;
