[PATCH 1/3] ARM: OMAP4: Update timer clock aliases (fwd)

Hi Tony,

well it seems that I did miss at least one important clock patch for v3.8.  
This appears to be needed to avoid failures when attempting to set parent 
clocks for GPTIMER5-7 on OMAP4.  Could you consider this one for late 
v3.8?  If you prefer, I can send a pull request for it.  Otherwise, will 
send it as part of the v3.8-rc1 integration fixes.

thanks,


- Paul

Yes this is still needed for v3.8.

Thanks, looks good to me.

Subject: [PATCH] ARM: OMAP4: Update timer clock aliases

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.
