[PATCH v2] dt-bindings: serial: 8250_omap: add rs485-rts-active-high

[PATCH v2] dt-bindings: serial: 8250_omap: add rs485-rts-active-high

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add rs485-rts-active-high property, this was removed by mistake.
In general we just use rs485-rts-active-low property, however the OMAP
UART for legacy reason uses the -high one.

Fixes: 767d3467eb60 ("dt-bindings: serial: 8250_omap: drop rs485 properties")
Closes: https://lore.kernel.org/all/ZGefR4mTHHo1iQ7H@francesco-nb.int.toradex.com/

Thanks for your patch, which is now commit 403e97d6ab2cb6fd
("dt-bindings: serial: 8250_omap: add rs485-rts-active-high")
in v6.4-rc5.

make dt_binding_check complains:

    Documentation/devicetree/bindings/serial/8250_omap.yaml:
rs485-rts-active-high: missing type definition

This property should have been added to
Documentation/devicetree/bindings/serial/serial.yaml first.

Nope, and I tried to update it and now everything fails in a miserable
way.

In any case the fix is clear and I am pretty confident the issue I had is
what you just wrote, I'll send a patch.
