2008-11-18Blackfin arch: Convert Blackfin GPIO driver to use common gpiolib/gpiochip infrastructureMichael Hennerich3-30/+140
- This patch adds support for ARCH_WANT_OPTIONAL_GPIOLIB. - It may be changed in future to ARCH_REQUIRE_GPIOLIB. - Change GPIO_BANK_NUM use DIV_ROUND_UP( , ) macro Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2008-11-18Blackfin arch: Cleanup and unify Blackfin IRQ and GPIO IRQ handlingMichael Hennerich1-125/+66
- 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.

2008-11-18Blackfin arch: remove useless SSYNC() in irq priority codeMike Frysinger1-4/+0
- remove SSYNC() left over from irq init split - do not force SSYNC() when masking/unmasking IRQs in the SIC as any order enforced by the hardware should already be enforced by software Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>
2008-11-18Blackfin arch: fix bug - gpio_bank() macros messed up bank number caculating with positioning a gpioBryan Wu3-18/+20
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.

2008-11-18Blackfin arch: update defconfig file for all boardsMike Frysinger21-47/+38
- do not bother generating deprecated /sys files by default now since mdev does not need it - Don't built-in char sport driver and build it as a module in defconfig - disable CONFIG_DEVKMEM by default - enable spi flash driver on boards that have one - switch config to the NAND platfrom driver rather than the bfin async one - do not make BFIN_DMA_5XX optional since a large portion of our code relies on dma functions existing Signed-off-by: Mike Frysinger <vapier.adi@gmail.com> Signed-off-by: Bryan Wu <cooloney@kernel.org>

2009-01-06Fix up 64-bit byte swaps for most 32-bit architecturesLinus Torvalds1-1/+1
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.
