| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a serial port continuously experiences input overrun from (1) continuous receive characters from remote and or (2) hardware issues, its interrupt handler can preempt other tasks especially when the system is busy (ie. boot up period). This can cause other tasks to get starved of processing time from the CPU. When this dts binding is enabled and input overrun on the serial port is detected, serial port receive will be throttled to give some breathing room for processing other tasks. Value provided will be in milliseconds. &serial0{ overrun-throttle-ms = <500>; }; Signed-off-by: Darwin Dingel <darwin.dingel@alliedtelesis.co.nz> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i.MX UART peripheral uses the RST_B signal as input, and CTS_B as output. This is just like the DCE role in RS-232. This is true regardless of the "DTE mode" setting of this peripheral. As a result, rs485 support hardware must use the CTS_B signal to control the RS-485 transceiver. This is in contrast to generic rs485 kernel code, documentation, and DT property names that consistently refer to the RTS as transceiver control signal. Add a note in the DT binding document about that, to reduce the confusion somewhat.

| | | | | | | | | | | | | | | | | | | | | | | | As a kernel newcomer, I got bitten by lack of examples on this front. I had troubles figuring out where these clocks could be defined ("/clocks" is where the generic infrastructure expects them). One should also ensure that a unique name is used. Generic names such as "osc" tend to be already used by some board-wide clock crystals.
