2018-12-17dt-bindings: serial: 8250: Add rate limit for serial port input overrunsDarwin Dingel1-0/+1
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 FIFO size of the UART devices is 64 on almost all UniPhier SoCs with the exception Pro4TV SoC (MN2WS0235), which used 128 FIFO size. However, Pro4TV SoC was never upstreamed, and out of production. So, this property has never been used in a useful way. Let's remove old unused code.
