Blackfin arch: Cleanup and unify Blackfin IRQ and GPIO IRQ handling · 8d022374

Michael Hennerich authored Nov 18, 2008

 - Remove SSYNC()
 - Use irq_to_gpio where applicable
 - Remove gpio_edge_triggered bitfield, check irq_desc fields instead.
 - Remove gpio_both_edge_triggeredb bitfield, check irq_desc fields
   instead.
 - Use BITMAP and bitops on gpio_enabled
 - Preferably use 32-bit
 - Looking at the disassembly this indeed saves quite a few instructions.

Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating... · 397861cd

Bryan Wu authored Nov 18, 2008

Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating with positioning a gpio

The whole story:

Before BF51x merged, all the MAX_BLACKFIN_GPIOS are integral multiple of GPIO_BANKSIZE (= 16).
But BF51x provides MAX_BLACKFIN_GPIOS = 40 which includes 3 banks and the 3rd bank has only 8
GPIO pins.

Therefore, gpio_bank() macros is correct when you try to find a GPIO in which bank (GPIO_35 is
in bank 2). But on BF51x gpio_bank(MAX_BLACKFIN_GPIOS) only gives out 2 banks instead of 3
banks for some static array initialization.

This patch add a new macros gpio_bank_n() and GPIO_BANK_NUM to do bank number caculating and
remain the gpio_bank() macros for positioning a gpio in which bank.

Fix up 64-bit byte swaps for most 32-bit architectures · ede6f5ae

Linus Torvalds authored Jan 06, 2009

The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the
no-longer-existant ___swab32() method (three underscores). We got rid
of some of the worst indirection and complexity, and now it should just
use the 32-bit swab function that was defined right above it.
