blackfin: adi gpio driver and pinctrl driver support

2013-11-15T09:33:42+00:00

Remove gpio driver for new gpio controller on BF54x and BF60x. Build the bfin_gpio driver only when other BF5xx processors are selected. Replace the prefix of some gpio and peripheral functions with adi. add portmux platform data in machine portmux.h Signed-off-by: Sonic Zhang Signed-off-by: Steven Miao

Blackfin: bfin_gpio: Use proper mask for comparing pfunc

2013-11-15T09:33:41+00:00

For BF537_FAMILY, when offset != 1, the mask is 1. Thus add proper mask for comparing pfunc with function. Also has small refactor for better readability. In portmux_setup(), it looks odd having "pmux &= ~(3 << 1);" while in current code we do pmux |= (function << offset);. Signed-off-by: Axel Lin Signed-off-by: Sonic Zhang

Blackfin: bf54x: fix GPIO resume code

2011-07-23T05:18:32+00:00

Back in commit c03c2a87347b849ec927d, we fixed logic in the non-bf54x GPIO resume code to set the data levels properly before the direction to avoid spurious line glitches. But we missed the bf54x code paths. So add the same fix there. Signed-off-by: Mike Frysinger

Blackfin: bf538: pull gpio/port logic out of core hibernate paths

2011-07-23T05:18:30+00:00

Re-architect how we save/restore the gpio/port logic that only pertains to bf538/bf539 parts by pulling it out of the core code paths and pushing it out to bf538-specific locations. Signed-off-by: Mike Frysinger

Blackfin: switch /proc/gpio to seq_file

->read_proc interface is going away, switch to seq_file. Signed-off-by: Alexey Dobriyan Signed-off-by: Mike Frysinger

Blackfin: bf537: demux port H mask A and emac rx ints

2011-05-25T12:13:43+00:00

The BF537 SIC combines the gpio port H mask A interrupts with the emac rx interrupt, so we need to demux this in software. It also combines the gpio port H mask B and the emac tx interrupts, and the watchdog and port F mask B interrupts, but since we don't support mask B yet, just add the defines for now.

Blackfin: move internal irq prototypes out of global namespace

2011-05-25T12:13:43+00:00

These are only used in a few internal Blackfin places, so move the irq prototypes out of the global header and into the internal irq one. No functional changes other than shuffling locales. Signed-off-by: Mike Frysinger
