Yixun Lan e3678b6470 pinctrl: nand: meson-gxbb: fix missing data pins
The data pin 0-7 of the NAND controller are actually missing from
the nand pinctrl group, so we fix it here.

Jerome Brunet ce385aa24a pinctrl: meson: rework pinmux ops
This change prepare the introduction of new meson SoC. This new SoC will
share the same gpio/pinconf registers but the pinmux part will be
different. While the format of the data associated with each pinmux group
will change, the way to handle pinmuxing will be similar.

To deal with this new situation, the meson_pmx_struture is kept but the
data associated to it is now generic. This allows to reuse the basic
functions which would otherwise be copy/pasted in each pinmux driver
(such as getting the name a count of groups and functions) Only the
functions actually using this specific data is taken out of the common
code and is handling the SoC pinmuxing

Jerome Brunet 277d14eb81 pinctrl: meson: separate soc drivers
When meson pinctrl is enabled, all meson platforms pinctrl drivers are
built in the kernel, with a significant amount of data.

This leads to situation where pinctrl drivers targeting an architecture
are also compiled and shipped on another one (ex: meson8 - ARM - compiled
and shipped on ARM64 builds). This is a waste of memory we can easily
avoid.

This change makes 4 pinctrl drivers (1 per SoC) out the original single
driver, allowing to compile and ship only the ones required.

Jerome Brunet 634e40b0c2 pinctrl: meson: remove offset from pinctrl
Offset on meson pinctrl and gpios is something that was carried from the
vendor driver, where there is a weird link between the 2
controllers. Since these 2 controllers are independent, this offset adds
an unnecessary complexity.

This patch remove this manually set offset and rely on pinctrl to figure
out the gpio base offset

Merge tag 'pinctrl-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of pin control changes for the v4.12 cycle.

  The extra week before the merge window actually resulted in some of
  the type of fixes that usually arrive after the merge window already
  starting to trickle in from eager developers using -next, I'm
  impressed.

  I have recruited a Samsung subsubsystem maintainer (Krzysztof) to deal
  with the onset of Samsung patches. It works great.

  Apart from that it is a boring round, just incremental updates and
  fixes all over the place, no serious core changes or anything exciting
  like that. The most pleasing to see is Julia Cartwrights work to audit
  the irqchip-providing drivers for realtime locking compliance. It's
  one of those "I should really get around to looking into that" things
  that have been on my TODO list since forever.

  Summary:

  Core changes:

Martin Blumenstingl b27e36482c pinctrl: meson: fix uart_ao_b for GXBB and GXL/GXM
The GXBB and GXL/GXM pinctrl drivers had a configuration which conflicts
with uart_ao_a. According to the GXBB ("S905") datasheet the AO UART
functions are:
- GPIOAO_0: Func1 = UART_TX_AO_A (bit 12), Func2 = UART_TX_AO_B (bit 26)
- GPIOAO_1: Func1 = UART_RX_AO_A (bit 11), Func2 = UART_RX_AO_B (bit 25)
- GPIOAO_4: Func2 = UART_TX_AO_B (bit 24)
- GPIOAO_5: Func2 = UART_RX_AO_B (bit 25)

The existing definition for uart_AO_A already uses GPIOAO_0 and GPIOAO_1.
The old definition of uart_AO_B however was broken, as it used GPIOAO_0
for TX (which would be fine) and two pins (GPIOAO_1 and GPIOAO_5) for RX
(which does not make any sense).

This fixes the uart_AO_B configuration by moving it to GPIOAO_4 and
GPIOAO_5 (it would be possible to use GPIOAO_0 and GPIOAO_1 in theory,
but all existing hardware uses uart_AO_A there).
The fix for GXBB and GXL/GXM is identical since it seems that these
specific pins are identical on both SoC variants.

Beniamino Galvani db80f0e158 pinctrl: meson: get rid of unneeded domain structures
The driver originally supported more domains (register ranges) per
pinctrl device, but since commit 9dab1868ec ("pinctrl: amlogic: Make
driver independent from two-domain configuration") each device gets
assigned a single domain and we instantiate multiple pinctrl devices
in the DT.

Therefore, now the 'meson_domain' and 'meson_domain_data' structures
don't have any reason to exist and can be removed to make the model
simpler to understand. This commit doesn't change behavior.

Tested on a Odroid-C2.
