Use the same cache terminology as the ARM docs in comments. No functional changes. Use armv7 TLB flush code, not arm11, for cortex-a processors. Exynos/ Arndale... - Disable debugging by default. - Add display-related and clk devices to the tree - Prevent resources intersection with EHCI driver - Add display-related and clk devices to the tree - Prevent resources intersection with EHCI driver - Add driver for Display Controller. - Add support for Samsung Chromebook (ARM Cortex A15 machine). - Rename mct and ehci drivers files to match common naming.
