[PATCH 1/5] clocksource: st_lpc: Add LPC timer as a clocksource.

2015-04-17 Thread Peter Griffin
This patch adds support for the LPC timer as a clocksource which is found on stih407 family SoCs. We wish to use the LPC timer as a clocksource instead of arm_global_timer, as the latter is tied to CPU frequency, and that driver currently makes no account for frequency scaling. Once this driver i
