From: Lino Sanfilippo <l.sanfilippo@xxxxxxxxxx> 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.
