That should get fixed for v3.13 when we get the proper DT clocks
for omap. Currently twd_get_clock() currently does:

	if (np)
		twd_clk = of_clk_get(np, 0);
	else
		twd_clk = clk_get_sys("smp_twd", NULL);

So if fails in the np case right now.

I'd probably wait for v3.13 on this one to avoid adding
temporary timer workarounds to twd_get_clock() or stuffing
the clock for the timer by using of_clk_add_provider().

If people feel strongly that we should fix it for v3.12,
then let me know. Things do work without it, of course the
local timer is not being used though.

Thanks that's an easy one. I'll queue the following fix.

Regards,

Tony

Subject: [PATCH] ARM: OMAP4: Fix clock_get error for GPMC during boot

Looks like we still have the legacy clock alias name for
omap4 GPMC (General Purpose Memory Controller), so let's
fix it for the device tree naming. There's no need to keep
the legacy naming as omap4 is DT only nowadays.

Without this fix we get the following error while booting:

[    0.440399] omap-gpmc 50000000.gpmc: error: clk_get
