ARM: iop32x: merge everything into mach-iop32x/

2019-08-14T13:36:22+00:00

Various bits of iop32x are now in their traditional locations in plat-iop,
mach-iop/include/mach/ and in include/asm/mach/hardware. As nothing
outside of the iop32x mach code references these any more, this can all
be moved into one place now.

The only remaining things in the include/mach/ directory are now the
NR_IRQS definition, the entry-macros.S file and the the decompressor
uart access. After the irqchip code has been converted to SPARSE_IRQ
and GENERIC_IRQ_MULTI_HANDLER, it can be moved to ARCH_MULTIPLATFORM.

dma: iop-adma: allow building without platform headers

2019-08-14T13:36:22+00:00

Now that iop3xx and iop13xx are gone, the iop-adma driver no
longer needs to deal with incompatible register layout defined
in machine specific header files.

Move the iop32x specific definitions into drivers/dma/iop-adma.h
and the platform_data into include/linux/platform_data/dma-iop32x.h,
and change the machine code to no longer reference those.

The DMA0_ID/DMA1_ID/AAU_ID macros are required as part of the
platform data interface and still need to be visible, so move
those from one header to the other.

i2c: iop: Use GPIO descriptors

2019-06-12T11:20:23+00:00

The IOP3xx has some elaborate code to directly slam the
GPIO lines multiplexed with I2C down low before enablement,
apparently a workaround for a hardware bug found in the
early chips.

After consulting the developer documentation for IOP80321
and IOP80331 I can clearly see that this may be useful for
IOP80321 family (mach-iop32x) but it is highly dubious for
any 80331 series or later chip: in these chips the lines
are not multiplexed for UARTs.

We convert the code to pass optional GPIO descriptors
and register these only on the 80321-based boards where
it makes sense, optionally obtain them in the driver and
use the gpiod_set_raw_value() to ascertain the line gets
driven low when needed.

The GPIO driver does not give the GPIO chip a reasonable
label so the patch also adds that so that these machine
descriptor tables can be used.
