Subject: OMAP: DSS2: DSI: remove auto-update perf measurement
X-Git-Tag: firefly_0821_release~9833^2~3051^2~23
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1bbb275e261eb204795d4a48b3e485f2ad3d627c;p=firefly-linux-kernel-4.4.55.git

OMAP: DSS2: DSI: remove auto-update perf measurement

Remove performance measurement for auto-update. Auto-update and thus
performance measurement cannot be supported after the driver change where
the control is moved to display drivers.

This is part of a larger patch-set, which moves the control from omapdss
driver to the display driver.
