When making the pin control submenu globally visible, all kinds
of oddities appear, in blackfin a few files were #including
<linux/gpio.h> and relying on that to pull in <asm/gpio.h>.
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 <asm/gpio.h>
just not pulle in from just including <linux/gpio.h>
Simply add the required includes explicitly in the blackfin
kernel core and everything compiles fine.
Delete the use of the incorrect <linux/gpio.h> where possible.
Add stubs to <asm/gpio.h> 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.

There seems to be no need for separate ones since all users include both
files anyhow. Merge them because include/linux/i2c is to be deprecated.

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").

Interacting with the USB_PHY_TEST MMR through debugfs was causing wide-spread
chaos in the realm (kernel panic). Expunge all references to this demonic
register.

generic include
The ADI TWI peripheral is not binding to the Blackfin processor only.
The bits macros and structs should be put in the generic include header.
And update head file path in drivers accordingly.

Don't bind the code to specific CPU defines.

The hardware block uses the name "request" rather than "irq", so update
the struct accordingly.

Passing a non-simple expression in as the addr arg could incorrectly
apply the pointer cast resulting in misbehavior. Add proper paren.

The documentation for the IMDMA channels appears to be incorrect.
These DMA blocks don't actually have PERIPHERAL_MAP MMRs for us
to access. Attempts to do so lead to system mmr hardware errors.

The documentation is a little iffy as to whether these are actual MMRs,
but reading them on the hardware works, and the previous version of this
logic (the SDH) had PID[4567]. So add it for RSI too.

This code was mostly developed against a BF54x, so some BF537-specific
issues were missed.
The PPI block starts at PPI_CONTROL, not PPI_STATUS (which is the reverse
of the EPPI block).
The MDMA block starts at MDMA_NEXT_DESC_PTR, not MDMA_CONFIG. Seems the
sim does not catch misreads here so that'll need to get fixed.
The gptimer block is mostly 32bit regs, not 16bit. Use the gptimer struct
to figure that out rather than hardcoding it locally.
