Whilst making an unrelated change to some Documentation, Linus sayeth:
| Afaik, even in Britain, "whilst" is unusual and considered more | formal, and "while" is the common word. | | [...] | | Can we just admit that we work with computers, and we don't need to | use þe eald Englisc spelling of words that most of the world never | uses?
dictionary.com refers to the word as "Chiefly British", which is probably an undesirable attribute for technical documentation.
Replace all occurrences under Documentation/ with "while".

dt-bindings: serial: Add common rs485 binding for RTS polarity
rs485 allows for robust half-duplex serial communication. It is often implemented by attaching an rs485 transceiver to a UART. The UART's RTS line is wired to the transceiver's Transmit Enable pin and determines whether the transceiver is sending or receiving.
Examples for such transceivers are Maxim MAX13451E and TI SN65HVD1781A: https://datasheets.maximintegrated.com/en/ds/MAX13450E-MAX13451E.pdf http://www.ti.com/lit/ds/symlink/sn65hvd1781a-q1.pdf
In the devicetree, the transceiver itself is not represented, only the UART is. A few rs485-specific dt-bindings already exist and these go into the UART's device node.
This commit adds a binding to set the RTS polarity. Most (if not all) transceivers require the Transmit Enable pin be driven high for sending, but in some cases boards may negate the pin and RTS must then be driven low. Consequently the polarity defaults to active high but can be inverted with the newly added "rs485-rts-active-low" binding.
Document this binding in rs485.txt and in the two drivers fsl-imx-uart and fsl-lpuart that are about to be amended with support for it.
Curiously, the omap_serial driver defaults to active low and already supports an "rs485-rts-active-high" binding to invert the polarity. This is left unchanged to retain compatibility, but the binding is herewith documented.

dt-bindings: serial/rs485: make rs485-rts-delay optional
There are a few device trees that specify one of the already optional properties without also having the up to now required property rs485-rts-delay. Additionally there is no technical reason to require rs485-rts-delay and that's also what most drivers implement.
So give existing users and implementers a blessing and document rs485-rts-delay as optional.

dt-bindings: serial: Add common rs485 binding for RTS polarity rs485 allows for robust half-duplex serial communication. It is often implemented by attaching an rs485 transceiver to a UART. The UART's RTS line is wired to the transceiver's Transmit Enable pin and determines whether the transceiver is sending or receiving. Examples for such transceivers are Maxim MAX13451E and TI SN65HVD1781A: https://datasheets.maximintegrated.com/en/ds/MAX13450E-MAX13451E.pdf http://www.ti.com/lit/ds/symlink/sn65hvd1781a-q1.pdf In the devicetree, the transceiver itself is not represented, only the UART is. A few rs485-specific dt-bindings already exist and these go into the UART's device node. This commit adds a binding to set the RTS polarity. Most (if not all) transceivers require the Transmit Enable pin be driven high for sending, but in some cases boards may negate the pin and RTS must then be driven low. Consequently the polarity defaults to active high but can be inverted with the newly added "rs485-rts-active-low" binding. Document this binding in rs485.txt and in the two drivers fsl-imx-uart and fsl-lpuart that are about to be amended with support for it. Curiously, the omap_serial driver defaults to active low and already supports an "rs485-rts-active-high" binding to invert the polarity. This is left unchanged to retain compatibility, but the binding is herewith documented.

dt-bindings: serial/rs485: make rs485-rts-delay optional There are a few device trees that specify one of the already optional properties without also having the up to now required property rs485-rts-delay. Additionally there is no technical reason to require rs485-rts-delay and that's also what most drivers implement. So give existing users and implementers a blessing and document rs485-rts-delay as optional.
