OMAP54XX and DRA7XX SoCs have 8 banks per 32 GPIOs, that is, 256 in total. The DRA7xx config defines CONFIG_DRA7XX, but also includes omap5_common.h, where CONFIG_OMAP54XX is defined (due to sharing of many internal IPs with the OMAP5, including GPIO).

Hi Lubomir, I'd appreciate if you can test this patch serial ( mainly for OMAP5 ).
