blackfin: gpio: switch to gpiochip_add_data()

2016-02-19T08:51:42+00:00

We're planning to remove the gpiochip_add() function to swith
to gpiochip_add_data() with NULL for data argument.

blackfin: gpio: Be sure to clamp return value

2016-01-25T17:02:09+00:00

As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

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

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);.

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.

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.
