2022-03-18dt-bindings: serial: samsung: Add ARTPEC-8 UARTVincent Whitchurch1-0/+2
Add a compatible for the UART on the ARTPEC-8 SoC. This hardware block is closely related to the variants used on the Exynos chips. The register layout is identical to Exynos850 et al but the fifo size is different (64 bytes in each direction for all instances).

2021-09-14dt-bindings: serial: uartlite: Add properties for synthesis-time parametersSean Anderson1-0/+37
The uartlite device is a "soft" device. Many parameters, such as baud rate, data bits, and the presence of a parity bit are configured before synthesis and may not be changed (or discovered) at runtime. However, we must know what these settings are in order to properly calculate the uart timeout (and to inform the user about the actual baud of the uart). These properties are present for out-of-tree bindings generated by Xilinx's tools. However, they are also (mostly) present in in-tree bindings. I chose current-speed over xlnx,baudrate primarily because it seemed to be used by more existing bindings. Although these properties are marked as "required", note that only current-speed is required by the driver itself. Hopefully, this will allow for an easier transition.
