The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx. A lot of machine macros are used to accomodate both code in one gpio driver. This patch split the old gpio driver and move new gpio2 support to the generic gpio driver folder.
- To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the
board's config header file.
- The gpio2 driver supports bf54x, bf60x and future ADI processors, while
the older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561.
- All blackfin specific gpio function names are replaced by the generic
gpio APIs.
the code in u-boot was written so as to make direct import from the kernel trivial. that way there is only one code base to maintain -- the kernel. last i looked, you hadn't split the drivers in the kernel, which means things are now diverging.
Don't worry. I will do it in Linux kernel soon after this is merged into u-boot.
