Hi I am seeing some junk characters on uart boot console on DRA72x platform [1] and even on other TI platforms, did a bisect and found the commit "761ed4a94582" broke it first.
By reverting below two commit, I don't see the issue logs [2]. 761ed4a94582 "tty:serial_core: convert uart_close to use tty_port_close" a5a2b13074fd "serial: core: fix potential NULL pointer dereference" [1] - http://pastebin.ubuntu.com/23343431/ [2] - http://pastebin.ubuntu.com/23343435/ Regards Mugunthan V N
