Blackfin arch: Finalize the generic gpio support - add gpio_to_irq and irq_to_gpio
Blackfin arch: Advertise GENERIC_GPIO and remove duplicated GENERIC_CALIBRATE_DELAY
Blackfin arch: Add PORT_J.High (needed for BF548-EZkit Touchscreen interrupts) - remove PORT_C.H
Blackfin arch: add missing gpio error handling to make sure we roll back requests in case one fails
Blackfin serial driver: use new GPIO API
Blackfin SPI driver: Make BF54x SPI work and add support for portmux API
Blackfin SPI driver: use new GPIO API and add error handling

Mike Frysinger (1):
Blackfin arch: scrub remaining ASSEMBLY usage since the switch to __ASSEMBLY__
