Hello. Sorry for delay: I'm on vacations and WiFi didn't work well here... On 09/08/2014 03:17 PM, Ulf Hansson wrote:
I spent a couple of days with the driver just hanging due to me forgetting to specify the external crystal frequency, so that clk_get_rate() returned 0 and thus the loop in tmio_mmc_set_clock() never ended. I don't think that's an acceptable behavior, so I suggest that the minimum frequency is checked for 0 in tmio_mmc_host_probe().

Hi Sergei,
Could you please base it towards "next" instead, it doesn't apply. If you think this is important to go stable, I suggest you to add a stable tag for it.
It's a bit of a corner case, of course, but the consequences are just too disastrous: AFAIR, an ARM kernel just silently hangs on boot, with no hints of where. So I'm going to CC: -stable.
Kind regards Uffe
