bfin: Move gpio support for bf54x and bf60x into the generic driver folder. 2013-05-13T08:30:27+00:00 Sonic Zhang sonic.zhang@analog.com 2013-05-02T05:46:21+00:00 da34aae5fba36c1f1989fdd41fffa723f300eaad 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.

Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.

Add gpio driver and change Microblaze reset logic to be done
via gpio subsystem.

There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.

Adding several gpios IP is also possible and supported.

For listing gpio configuration please use "gpio status" command

This patch also remove one compilation warning:

For more details, see: http://www.broadcom.com/products/BCM2835 http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf. Initial support is enough to boot to a serial console, execute a minimal set of U-Boot commands, download data over a serial port, and boot a Linux kernel. No storage or network drivers are implemented. GPIO driver originally by Vikram Narayanan <vikram186@gmail.com> with many fixes from myself. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
