Rework the common helper function for retrieving rs485 properties to be platform agnostic (patch [1/5]) and to allow specifying the RTS polarity (patch [2/5] and [3/5]). Amend the fsl_lpuart and imx drivers to take advantage of this and fix a bunch of bugs while at it (patch [4/5] and [5/5]). Changes v1 -> v2: Patch [1/5]: - Replace "requested" with "asked for" in commit message. (Uwe) - Drop comment "common device tree parsing helpers" from serial_core.h, it is no longer applicable now that the helper isn't DT-specific. (Uwe) Patch [2/5]: - Add Rob's ack. Patch [3/5]: - Rework uart_get_rs485_mode() to unconditionally set up the flags for active-high polarity, then change them only if active-low polarity was configured in the device properties. (Uwe) - Drop line from imx.c which unconditionally sets the RTS_ON_SEND bit. Previously this change was made in patch [5/5].
