2019-08-14ARM: iop32x: merge everything into mach-iop32x/Arnd Bergmann
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.

2019-08-14ARM: remove Intel iop33x and iop13xx supportArnd Bergmann
There are three families of IOP machines we support in Linux: iop32x (which includes EP80219), iop33x and iop13xx (aka IOP34x aka WP8134x). All products we support in the kernel are based on the first of these, iop32x, the other families only ever supported the Intel reference boards but no actual machine anyone could ever buy. While one could clearly make them all three work in a single kernel with some work, this takes the easy way out, removing the later two platforms entirely, under the assumption that there are no remaining users. Earlier versions of OpenWRT and Debian both had support for iop32x but not the others, and they both dropped iop32x as well in their 2015 releases.

2019-06-12i2c: iop: Use GPIO descriptorsLinus Walleij
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.
