Subject: [PATCH v6 08/16] ARM: Exynos4: allow legacy board support to specify xxti and xusbxti clock speed
Date: Mon, 18 Feb 2013 13:51:18 +0530 [thread overview]
Message-ID: <1361175686-19400-9-git-send-email-thomas.abraham@linaro.org> (raw)
In-Reply-To: <1361175686-19400-1-git-send-email-thomas.abraham@linaro.org>
The clock speed of xxti and xusbxti clocks depends on the oscillator used on the
board to generate these clocks. For non-dt platforms, allow the board support
for those platforms to set the clock frequency of xxti and xusbxti clocks.
