2022-02-08dt-bindings: serial: renesas,scif: Document RZ/G2UL SoCBiju Das1-1/+2
Add SCIF binding documentation for Renesas RZ/G2UL SoC. SCIF block on RZ/G2UL is identical to one found on the RZ/G2L SoC. No driver changes are required as RZ/G2L compatible string "renesas,scif-r9a07g044" will be used as a fallback. Whilst dropped the comments after RZ/G2{L,LC} fallback as to avoid updating the comment over and over again when a new IP is added Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> Link: https://lore.kernel.org/r/20220207142213.19552-2-biju.das.jz@bp.renesas.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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.

Both UARTs support higher baudrates and are not limited to baudrate 230400. Only current kernel driver implementation has limitation for both UARTs in maximal baudrate 230400. This limitation will be removed in next patches. So remove incorrect information about (hardware) limitation from bindings. UART1 (standard variant with DT node name 'uart0') has register space 0x12000-0x12018 and not whole size 0x200. So fix also this in example.

2021-06-21dt-bindings: Drop redundant minItems/maxItemsRob Herring2-3/+0
If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.
