arch: remove blackfin port

2018-03-16T09:55:47+00:00

The Analog Devices Blackfin port was added in 2007 and was rather active for a while, but all work on it has come to a standstill over time, as Analog have changed their product line-up. Aaron Wu confirmed that the architecture port is no longer relevant, and multiple people suggested removing blackfin independently because of some of its oddities like a non-working SMP port, and the amount of duplication between the chip variants, which cause extra work when doing cross-architecture changes.

blackfin: Fix local includes

2017-10-19T08:12:49+00:00

When making the pin control submenu globally visible, all kinds of oddities appear, in blackfin a few files were #including and relying on that to pull in . This was not working when pin control but not GPIOLIB was selected resulting in a breakage in allmodconfig. The code these files were using was still there and defined in just not pulle in from just including Simply add the required includes explicitly in the blackfin kernel core and everything compiles fine. Delete the use of the incorrect where possible. Add stubs to for the functions called from PM: these should probably also depend on !PINCTRL but since the global CONFIG_PM symbol is used to compile PM support, we need some more intrusive thing here, to be tested by Blackfin maintainers.

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. Cc: Sonic Zhang Cc: Steven Miao Cc: adi-buildroot-devel@lists.sourceforge.net Acked-by: Sonic Zhang Signed-off-by: Linus Walleij

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. Cc: Steven Miao Cc: adi-buildroot-devel@lists.sourceforge.net Acked-by: Sonic Zhang Signed-off-by: Linus Walleij

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
