[PATCH 11/13 v5] OMAP: GPIO: Make gpio_context as part of gpio_bank structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



gpio_context array, which is used to save gpio bank's context,
is used only for OMAP3 architecture.

This patch moves gpio_context as part of gpio_bank structure
so that it can be specific to each gpio bank and can be
used for any OMAP architecture
