Subject: [PATCH 1/3] ARM: OMAP4: Update timer clock aliases
Date: Wed, 7 Nov 2012 12:43:00 -0600 [thread overview]
Message-ID: <1352313782-21602-2-git-send-email-jon-hunter@ti.com> (raw)
In-Reply-To: <1352313782-21602-1-git-send-email-jon-hunter@ti.com>
Commit "ARM: dts: OMAP4: Update timer addresses" updated the device-tree
names of the OMAP4 timers 5-7 because the default address for the timers
was changed from the L3 address to the MPU private address. When booting
with device-tree, this introduces a regression when attempting to set
the parent clock of timers 5-7 to the sys_clk_div_ck. Therefore, update
the clock aliases for timer 5-7 to reflect the updated device-tree name
for the timers.
Signed-off-by: Jon Hunter <jon-hunter@ti.com>

This change is needed for v3.8 as the patch [1] to update the default
timer addresses is queued for that release.
