Subject: [PATCH 1/4] ARM: tegra: clock: add i2c fast clock entry in clock table
Date: Wed, 8 Aug 2012 13:21:31 +0530	[thread overview]
Message-ID: <1344412294-2420-2-git-send-email-ldewangan@nvidia.com> (raw)
In-Reply-To: <1344412294-2420-1-git-send-email-ldewangan-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Tegra's i2c controller require two clock sources named as
div-clk and fast-clk for proper operation.
Currently, the entry of fast-clk is missing in tegra30
clock table and it is incorrectly named in the tegra20
clock table.
Adds aliases to enable lookups for "fast-clk" to succeed.
A later patch will remove the incorrectly named clock,
once the driver is modified to use the new name.
