upper layers, namely line discipline, need to be notified when transmission of more data is possible.

"have_rtscts" is assigned 1, while it is declared int:1, two's complement, which can hold 0 and -1 only. The code works, as the upper bits are cut off, and tests are done against 0 only. Nonetheless, correctly declaring the bit field as unsigned int:1 renders the code more robust.

The interrupt handler for muxed interrupts (imx2/imx3) was calling the rts handling subroutine if the RTSS bit was set. (Which indicates the status of the RTS line), leading to an interrupt flood on RTS bit low. This patch fixes the problem by looking at the RTSD bit instead, indicating a change in the RTS line.

Do not use the URXD_CHARRDY bit for polling for new characters. This works on i.MX1, but on MX31 the datasheet states that this bit should not be used for polling.

Since 43cc71ee, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable serial platform drivers, to re-enable auto loading. NOTE that Kconfig for some of these drivers doesn't allow modular builds, and thus doesn't match the driver source's unload support. Presumably their unload code is buggy and/or weakly tested...
