Subject: clocksource/drivers/tegra: Add verbose definition for 1MHz constant
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2e08a4bb96fd275d42711af10b3484164046bd1d;p=openwrt%2Fstaging%2Fblogic.git

clocksource/drivers/tegra: Add verbose definition for 1MHz constant

Convert all 1MHz literals to a verbose constant for better readability.
