Subject: ARM: plat-nomadik: use DIV_ROUND_CLOSEST()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2136683172f49a32b3ed7469f6e5ce20c8f4278b;p=deliverable%2Flinux.git

ARM: plat-nomadik: use DIV_ROUND_CLOSEST()

Use DIV_ROUND_CLOSEST() to calculate the cycle counter for the
periodic mode instead of relying on homebrew reimplementation.
