[PATCH 1/2] [v2] tty: amba-pl011: fix earlycon register offsets

From: Timur Tabi <hidden>
Date: 2016-01-04 21:37:46
Also in: linux-arm-msm
Subsystem: arm primecell uart pl010 and pl011 drivers, the rest, tty layer and serial drivers · Maintainers: Russell King, Linus Torvalds, Greg Kroah-Hartman, Jiri Slaby

From: Russell King <redacted>

The REG_x macros are indices into a table, not register offsets.  Since earlycon
does not have access to the vendor data, we can currently only support standard
ARM PL011 devices.
