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.

gpio: Include linux/gpio.h instead of asm/gpio.h

2016-02-15T23:20:03+00:00

Most arches have an asm/gpio.h that merely includes linux/gpio.h. The others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected, linux/gpio.h includes asm/gpio.h. Therefore, code should include linux/gpio.h instead of including asm/gpio.h directly. Remove includes of asm/gpio.h, adding an include of linux/gpio.h when necessary. This is a follow-on to 7563bbf89d06 ("gpiolib/arches: Centralise bolierplate asm/gpio.h").

pm: sometimes wake up from suspend to RAM would fail

2015-04-23T13:34:32+00:00

Sometimes it fails to wake up from suspend to RAM, this is because we would flush the data cache by assemble command FLUSHINV before suspend to RAM, and there is a delay between this command execution and cache flush completion. Add a 1uS delay to works around this. Signed-off-by: Aaron Wu
