Vadim Bendebury e1abf87d43 libpayload: improve us timer accuracy ... In cases where timer clock frequency is not an integer number of megahertz, the calculations in timer_us() lack accuracy. This patch modifies calculations to reduce the error. The maximum interval this calculation would support decreases, but it still is in excess of 1844674 seconds for a timer clocked by 10 MHz, which is more than enough. BUG=none TEST=manual . verified timer accuracy using a depthcharge CLI command Change-Id: Iffb323db10e74b0ce3b4d59a56983bfee12e6805 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/207358 Reviewed-by: David Hendricks <dhendrix@chromium.org>		2014-07-11 01:55:41 +00:00
