From 9bef3d4197379a995fa80f81950bbbf8d32e9e8b Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Thu, 5 Jan 2012 18:21:43 -0500 Subject: serial: group all the 8250 related code together The drivers/tty/serial dir is already getting rather busy. Relocate the 8250 related drivers to their own subdir to reduce the clutter. Note that sunsu.c is not included in this move -- it is 8250-like hardware, but it does not use any of the existing infrastructure -- and does not depend on SERIAL_8250.
