Since there are more IOT2040 variants with identical hardware but
different asset tags, the asset tag matching should be adjusted to
support them.
For the board name "SIMATIC IOT2000", currently there are 2 types of
hardware, IOT2020 and IOT2040. Both are identical regarding the
intel_quark_i2c_gpio. In the future there will be no other devices with
the "SIMATIC IOT2000" DMI board name but different hardware. So remove
the asset tag matching from this driver.

The AXP223 can be used both using the RSB proprietary bus, or a more
traditional I2C bus. The RSB is a faster bus and provides more features
(like some integrity checks on the messages), so it's usually preferrable
to use it, but since it's proprietary, when we want to use the PMIC in a
multi-master setup, the i2c might make sense as well.
Let's add that possibility.

I noticed that we can get a -EREMOTEIO errors on at least omap4 duovero:
twl6040 0-004b: Failed to write 2d = 19: -121
And then any following register access will produce errors.
There 2d offset above is register ACCCTL that gets written on twl6040
powerup. With error checking added to the related regcache_sync() call,
the -EREMOTEIO error is reproducable on twl6040 powerup at least
duovero.
To fix the error, we need to wait until twl6040 is accessible after the
powerup. Based on tests on omap4 duovero, we need to wait over 8ms after
powerup before register write will complete without failures. Let's also
make sure we warn about possible errors too.
Note that we have twl6040_patch[] reg_sequence with the ACCCTL register
configuration and regcache_sync() will write the new value to ACCCTL.

On 32 bit ARM parts, handle in the same way as syscon.
On 64 bit ARM parts, the System Manager can only be accessed by
EL3 secure mode. Since a SMC call to EL3 is required, this new
driver uses regmaps similar to syscon to handle the SMC call.
Since regmaps abstract out the underlying register access, the
changes to drivers accessing the System Manager are minimal.

Core changes:
- The big change this time around is the irqchip handling in
the qualcomm pin controllers, closely coupled with the
gpiochip. This rework, in a classic fall-between-the-chairs
fashion has been sidestepped for too long. The Qualcomm
IRQchips using the SPMI and SSBI transport mechanisms have
been rewritten to use hierarchical irqchip. This creates
the base from which I intend to gradually pull support for
hierarchical irqchips into the gpiolib irqchip helpers to
cut down on duplicate code. We have too many hacks in the
kernel because people have been working around the missing
hierarchical irqchip for years, and once it was there,
noone understood it for a while. We are now slowly adapting
to using it. This is why this pull requests include changes
to MFD, SPMI, IRQchip core and some ARM Device Trees
pertaining to the Qualcomm chip family. Since Qualcomm have
so many chips and such large deployments it is paramount
that this platform gets this right, and now it (hopefully)
does.
- Core support for pull-up and pull-down configuration, also
from the device tree. When a simple GPIO chip support a
"off or on" pull-up or pull-down resistor, we provide a
way to set this up using machine descriptors or device tree.
If more elaborate control of pull up/down (such as
resistance shunt setting) is required, drivers should be
phased over to use pin control. We do not yet provide a
userspace ABI for this pull up-down setting but I suspect
the makers are going to ask for it soon enough. PCA953x
is the first user of this new API.
- The GPIO mockup driver has been revamped after some
discussion improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for
both testing and virtual prototyping, e.g. when you do
not yet have a GPIO expander to play with but really
want to get something to develop code around before
hardware is available. It's neat. The blackbox testing
usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating
flags.
- A new device core helper for devm_platform_ioremap_resource()
is funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped
I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.

We now using a common macro for PM operations in Intel LPSS driver,

Otherwise it's a bit fragile and requires a proper ordering

Currently the sm501 mfd driver can be compiled without any dependencies,
but through the use of dma_declare_coherent it really depends on
having DMA and iomem support. Normally we don't explicitly require DMA
support as we have stubs for it if on UML, but in this case the driver
selects support for dma_declare_coherent and thus also requires
memmap support. Guard this by an explicit dependency.

Now that ssbi-gpio is a proper hierarchical IRQ chip, and all in-tree
users of device tree have been updated, we can now drop the hack that
was introduced to disassociate the old Linux virq if a hwirq mapping
already exists. That patch was introduced to not break git bisect for
any existing boards.
This change was tested on an APQ8060 DragonBoard.

Check to see if the hwirq is already associated with another virq on
this IRQ domain. If so, then disassociate it before associating the
hwirq with the new virq.
This is a temporary hack that is needed in order to not break git
bisect for existing boards. The next patch in this series converts
ssbi-gpio to be a hierarchical IRQ chip, then there are several patches
to update all of the device tree files, and finally this patch will be
reverted within the same patch series.
IRQs for ssbi-gpio are all initially setup without an IRQ hierarchy
this driver is probed due to the interrupts property in device tree.
Once ssbi-gpio is converted to be a hierarchical IRQ chip in the next
patch, existing users of gpio[d]_to_irq() will call pmic_gpio_to_irq(),
and that will use the new IRQ chip code in ssbi-gpio that sets up the
IRQ in an IRQ hierarchy. The hwirq is now associated with two Linux
virqs and interrupts will not work as expected. This patch corrects
that issue.
This change was tested on an APQ8060 DragonBoard.

Convert the PM8XXX IRQ code to use the version 2 IRQ interface in order
to support hierarchical IRQ chips. This is necessary so that ssbi-gpio
can be setup as a hierarchical IRQ chip with PM8xxx as the parent. IRQ
chips in device tree should be usable from the start without having to
make an additional call to gpio[d]_to_irq() to get the proper IRQ on the
parent.
pm8821_irq_domain_ops and pm8821_irq_domain_map are removed by this
patch since the irq_chip is now contained in the pm_irq_data struct, and
that allows us to use a common IRQ mapping function.

While ioctls normally return a negative error or 0 on success, this is not
the case for CROS_EC_DEV_IOCXCMD in the cros_ec driver, which returns the
number of bytes read instead. However, CROS_EC_DEV_IOCRDMEM in the same
driver does not return the number of byte read on success. This is both
inconsistent and problematic, since the amount of returned data can be
dynamic. Have it return the number of data bytes for consistency.
