Subject[RESEND PATCH v3] serial/arc-uart: Add new driver
Date
From: Vineet Gupta <vgupta@synopsys.com>

Hi,

Please find following ARC UART driver with all the review comments incorporated.
It's rebased off of current tip (commit 12250d843e)

Please consider merging.

Thx,
-Vineet

v3:
* Removed empty arc_serial_set_ldisc()
* More set_termios fixes - CSIZE forced to CS8 (for 8N1)
* global @running_on_iss replaced with platform data, saved in device
specific port structure.

v2:
* ttyARC used as device name
* Dynamic assignment of major/minor numbers.
* Ref counting tty in rx routine to prevent it from disappearing in
case of a hangup
* set_termios fixes:
- hardware flow control/parity are marked as unsupported
- baud written back to termios
* cosmetics such as commenting the need for @running_on_iss, empty lines
etc
