Could you take a look into my tree and rebase these two? Note - you need only reply these two mails instead of submitting another set of patches, and do remember to attach the patch esp. since you are using gmail web interface, which is going to mal-form the patch. Thanks. - eric |

This is really a loooong delay, there any specific reason for such a long
delay, I'm seeing this to slow down the boot up significantly?
Otherwise looks OK to me, and I prefer the defconfig file change to
be a separate patch please.

Actually, This is just an example for other real products. There is no
such spi_reset pin on Aspenite , so machine info set it spi_gpio_reset
== -1. Or do you think we should delete these lines?

I see no reason for it to stay there then, please remove.

rebased to topic/pxa168fb branch of pxa git repository. changes include:
1. Delete redundant gpio operation in aspenite.c
2. change to include <linux/gpio.h>
