From: Nicolai Stange Date: Thu, 30 Mar 2017 19:45:28 +0000 (+0200) Subject: microblaze: Set ->min_delta_ticks and ->max_delta_ticks for timer X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bb26081a98d3db2fde37ff57f8276266b6158471;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git microblaze: Set ->min_delta_ticks and ->max_delta_ticks for timer In preparation for making the clockevents core NTP correction aware, all clockevent device drivers must set ->min_delta_ticks and ->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a clockevent device's rate is going to change dynamically and thus, the ratio of ns to ticks ceases to stay invariant. Make the microblaze arch's clockevent driver initialize these fields properly. This patch alone doesn't introduce any change in functionality as the clockevents core still looks exclusively at the (untouched) ->min_delta_ns and ->max_delta_ns. As soon as this has changed, a followup patch will purge the initialization of ->min_delta_ns and ->max_delta_ns from this driver.
