Subject[PATCH 0/8] Fixes and cleanup for RS485
Date
From: Lino Sanfilippo <l.sanfilippo@kunbus.com>

The following series includes cleanup and fixes around RS485 in the serial
core and uart drivers:

Patch 1: Only request the rs485 termination gpio if it is supported.
Patch 2: Set the rs485 termination GPIO in the serial core. This is needed
since if the gpio is only accessible in sleepable context. It also
is a further step to make the RS485 handling more generic.
Patch 3: Move sanitizing of RS485 delays into an own function. This is in
preparation of patch 4.
Patch 4: Sanitize RS485 delays read from device tree.
Patch 5: Correct RS485 delays in binding documentation.
Patch 6: Remove redundant code in 8250_dwlib.
Patch 7: Remove redundant code in ar933x.
Patch 8: Remove redundant code in 8250-lpc18xx.

This patchset is based tty-testing.

serial: core: only get RS485 termination gpio if supported
serial: core, 8250: set RS485 termination gpio in serial core
