[U-Boot] [PATCH v4] MX: Set a common gpio.h for all i.MX
Benoît Thébaudeau
benoit.thebaudeau at advansee.com
Mon Aug 20 22:33:12 CEST 2012
Hi Stefano,
> Each i.MX has its own gpio.h, defining the same structure.
> The internal GPIO controller has the same layout
> (at least for the register used by u-boot) and can be shared.

> Changes in v2:
> - please ignore this version, it is broken
>
> Changes in v3:
> - call the macro IMX_GPIO_NR as in kernel (Fabio Estevam)
> - change psr in gpio_psr (Benoit Thebaudeau)
> - drop MXC_GPIO_PORT_TO_NUM and use common macro (Benoit Thebaudeau)
>
> Changes in v4:
> - Add missing comment in commit message
