Hi Thomas,
The whole series looks much better now. Although there is still one more
thing from my comments to previous version unresolved, see the inline
comment.

This patch series is a work on improving usability and extensibiltiy of the
pinctrl-samsung driver. It consists of three main parts:
- moving SoC-specific data to device tree
- converting the driver to use one GPIO chip and one IRQ domain per pin bank
- introducing generic wake-up interrupt
Seuqential patches from this series introduce SoC-specific data parsing
from device tree.
This patch removes legacy GPIO bank nodes from exynos4210.dtsi and
replaces them with nodes and properties required for these patches.

This patch converts the pinctrl-exynos driver to parse wakeup interrupt
count and register offsets from device tree. It reduces the amount of

Currently SoC-specific properties such as list of pin banks, register

residing in pinctrl-exynos.c.

data from device tree, which will allow to remove the
Some SoCs, like Exynos4x12, have non-sequential layout of EINT control
registers and so current way of calculating register addresses does not
work correctly for them.

Instead of registering one IRQ domain for all pin banks of a pin
controller, this patch implements registration of per-bank domains.
At a cost of a little memory overhead (~2.5KiB for all GPIO interrupts
of Exynos4x12) it simplifies driver code and device tree sources,
because GPIO interrupts can
The pointer to gpio_chip passed to pin_to_reg_bank utility function is
used only to retrieve a pointer to samsung_pinctrl_drv_data structure.

This patch modifies the pinctrl-samsung driver to register one GPIO chip
per pin bank, instead of a single chip for all pin banks of the
controller.
It simplifies GPIO accesses a lot (constant time instead of looping
through the list of banks to find the right one) and should have a good
effect
This patch reworks wake-up interrupt handling in pinctrl-exynos driver,
so each pin bank, which provides wake-up interrupts, has its own IRQ
domain.
Information about whether given pin bank provides wake-up interrupts,
how many and whether they are separate or muxed are parsed from device
tree.
Pins used as wake-up interrupts need to be configured as EINTs. This
patch adds the required configuration code to exynos_wkup_irq_set_type,
to set the pin as EINT when its interrupt trigger type is configured.

Some drivers require a way to translate GPIO pins to their IRQ numbers.

This patch series aims to consolidate low level Kconfig entries for Exynos

This patch modifies the dependencies between Exynos-related Kconfig
options to represent the real dependencies between code units more
closely.
Originally it was possible to enable ARCH_EXYNOS{4,5} without any
SOC_EXYNOS_{4,5}.* enabled, which could end with compilation or link
errors. Now
This patch adds CONFIG_EXYNOS4X12, which is automatically selected
whenever there is at least one SoC from Exynos4x12 line enabled. All the
shared dependencies of EXYNOS{4212,4412} are moved to this new
option.
This fixes build with Exynos4412 enabled and Exynos4212 and Exynos4210
disabled and
MACH_EXYNOS{4,5}_DT are used for whole SoC lines, so they should depend
on ARCH_EXYNOS{4,5} rather than on particular SoCs.
