The newly introduced as3722_i2c_suspend/resume functions are built
unconditionally, but only used when power management is enabled,
so we get a warning otherwise:
drivers/mfd/as3722.c:427:12: warning: 'as3722_i2c_suspend' defined but not used [-Wunused-function]
drivers/mfd/as3722.c:438:12: warning: 'as3722_i2c_resume' defined but not used [-Wunused-function]
This marks them both as __maybe_unused, which avoids an ugly #ifdef
and gives us best compile-time coverage. When they are unused, the
compiler will silently drop the functions from its output.

"id[i] & 0xff".
But while there, it is much simpler to simply use %phN and do all the

Currently syscon has a fixed configuration of 32 bits for register and
values widths. In some cases, it would be desirable to be able to
customize the value width.
For example, certain boards (like the ones manufactured by Technologic
Systems) have a FPGA that is memory-mapped, but its registers are only
16-bit wide.
This patch adds an optional "reg-io-width" DT binding for syscon that
allows to change the width for the data bus (i.e. val_bits). If this
property is provided, it will also set the register stride to
reg-io-width's value. If not provided, the default configuration is
used.

cros_ec_cmd_xfer_spi and cros_ec_pkt_xfer_spi generally work like
this:
- Pull CS down (active), wait a bit, then send a command
- Wait for response (multiple requests)
- Wait a while, pull CS up (inactive)
These operations, individually, lock the SPI bus, but there is
nothing preventing the SPI framework from interleaving messages
intended for other devices as the bus is unlocked in between.
This is a problem as the EC expects CS to be held low for the
whole duration.
Solution: Lock the SPI bus during the whole transaction, to make
sure that no other messages can be interleaved.

The as3722 device is registered as an irqchip and the as3722-rtc interrupt
is one of it's interrupt sources. When using the as3722-rtc as a wake-up
device from suspend, the following is seen:
PM: Syncing filesystems ... done.
Freezing user space processes ... (elapsed 0.001 seconds) done.
Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done.
Suspending console(s) (use no_console_suspend to debug)
PM: suspend of devices complete after 161.119 msecs
PM: late suspend of devices complete after 1.048 msecs

Disabling non-boot CPUs ...

CPU2: shutdown

Entering suspend state LP1
Enabling non-boot CPUs ...

as3722 4-0040: Failed to read IRQ status: -16
as3722 4-0040: Failed to read IRQ status: -16
as3722 4-0040: Failed to read IRQ status: -16
as3722 4-0040: Failed to read IRQ status: -16
...
The reason why the as3722 interrupt status cannot be read is because the
as3722 interrupt is not masked during suspend and when the as3722-rtc
interrupt occurs, to wake-up the device, the interrupt is seen before the
i2c controller has been resumed in order to read the as3722 interrupt
status.
The as3722-rtc driver sets it's interrupt as a wake-up source during
suspend, which gets propagated to the parent as3722 interrupt. However,
the as3722-rtc driver cannot disable it's interrupt during suspend
otherwise we would never be woken up and so the as3722 must disable it's
interrupt instead.
Fix this by disabling the as3722 interrupt during suspend. To ensure that
a wake-up event from the as3722 is not missing, enable the as3722 interrupt
as a wake-up source before disabling the interrupt on entering suspend.

Based in the discussion this patch rename MFD regulator name as

Commit b158b69a37 ("mfd: rtsx: Simplify function return logic")
removed the use of the 'err' variable, but left the variable itself
around, resulting in gcc quite reasonably warning:
drivers/mfd/rtsx_pcr.c: In function ‘rtsx_pci_set_pull_ctl’:
drivers/mfd/rtsx_pcr.c:565:6: warning: unused variable ‘err’ [-Wunused-variable]
int err;
^
Get rid of the unused variable, and avoid the new warning.

Quite a lot of activity in SPI this cycle, almost all of it in drivers
with a few minor improvements and tweaks in the core.
- Updates to pxa2xx to support Intel Broxton and multiple chip selects.
- Support for big endian in the bcm63xx driver.
- Multiple slave support for the mt8173
- New driver for the auxiliary SPI controller in bcm2835 SoCs.
- Support for Layerscale SoCs in the Freescale DSPI driver.

This is quite a quiet release in terms of volume of patches but it
includes a couple of really nice core changes - the work Sascha has done
in particular is something I've wanted to get done for a long time but
just never got round to myself. Highlights include:
- Support from Sascha Hauer for setting the voltage of parent supplies
based on requests from their children. This is used both to allow
set_voltage() to work through a dumb switch and to improve the
efficiency of systems where DCDCs are used to supply LDOs by minimising
the voltage drop over the LDOs.
- Removal of regulator_list by Tomeu Vizoso, meaning we're not
duplicating the device list maintained by the driver core.
- Support for Wolfson/Cirrus WM8998 and WM1818.
