Hi all,
I've tested the lastest linus git kernel, and this kernel
no longer boot on my armadeus apf27. The last line of the
log are (after, the kernel is stalled) :

I've done a bisect and the commit that raise this issue is :
db2ae4b4f6b79bd11d6461d41bd0966b0006f20b
ARM: imx: provide gpt device specific irq functions
Do you also reproduce this issue please ? or may be I've missed
to enable an new option ?
I don't have access to a mx27 board at the moment, but I am wondering
if the change below would fix the problem:
I've got one, and I can do the test.

I've looked the code in drivers/clocksource/timer-imx-gpt.c, in the definition
of imx_gpt_type, there is :
GPT_TYPE_IMX21, /* i.MX21/27 */
So I've done a little change in your patch, I've used imx21_timer_init_dt for
imx27 :

I've tested it, and it works fine, now my apf27 (imx27) boot without any issue.
So good catch, thanks a lot for this patch.
I may send a patch on lkml if you want.
