This devicetree adds spidev nodes to the spi5 bus as enhancement to the
rk3399-puma.dts.

SPI core provides the functionality to have GPIO based chip selects but
assumes that the pins are already configured by the platform.
Configure GPIO style pins in rockchip_spi_setup so they can be used
later on.

Some SPI masters require slave selection before the transfer
can begin [1]. The SPI framework currently selects the chip using
either 1) the internal CS mechanism or 2) the GPIO CS, but not both.
This patch adds a new master->flags define to indicate both the GPIO
CS and the internal chip select mechanism should be used.

Access to the spi5 peripheral when powered down halts the system
rendering it unresponsive. Define the powerdomain in the rk3399.dtsi to
prevent a shutdown when the peripheral is used.

The SD-Card IO rail on the RK3399 should not be operated higher than
3.15V. We reduce it to 3.0V. Note that the I/Os on the Qseven edge
connector will still be 3.3V as expected.

Causes a kernel panic on the RK3399-Q7 "Puma".
See https://github.com/rockchip-linux/kernel/issues/79 for details.
This reverts commit 7e4349ec9d70dbcfe7f78125700d2685539ea1bd.

The UCAN driver supports the microcontroller-based USB/CAN
adapters from Theobroma Systems. There are two form-factors
that run essentially the same firmware:
* Seal: standalone USB stick ( https://www.theobroma-systems.com/seal )
* Mule: integrated on the PCB of various System-on-Modules from
Theobroma Systems like the A31-µQ7 and the RK3399-Q7
( https://www.theobroma-systems.com/rk3399-q7 )
The USB wire protocol has been designed to be as generic and
hardware-indendent as possible in the hope of being useful for
implementation on other microcontrollers.

The isl1208 emulation on puma / rk3399-q7 does not support interrupts at all,
but has no way to announce that fact to the kernel. This causes problems
in user-space:
# hwclock -r -D
[...]
select() to /dev/rtc to wait for clock tick timed out...synchronization failed
Set the uie_unsupported flag unconditionally in the driver until we get a
way to configure it through a device tree property. Fixes the problems
with hwclock.

BCM43455 is a more recent revision of the BCM4345. Some of the BCM43455
got a dedicated SDIO device ID which is currently not supported by
brcmfmac.
Adding the new sdio_device_id to brcmfmac is enough to get the BCM43455
supported because the chip itself is already supported (due to BCM4345
support in the driver).

devm_gpiod_get (but is not freeing the gpio_desc), change this
to use devm_gpiod_get so that the gpio will be properly released.

Input: silead_gsl1680 - document firmware-name, fix implementation
The driver has supported touchscreen-fw-name to specify the firmware to
load since it has been merged, but this was omitted from the dt-binding
documentation.
During review of adding touchscreen-fw-name to the binding documentation
it was brought up that there is a standard property name called
"firmware-name" for this, which should be used.
Since there are no users of touchscreen-fw-name yet, this commit
adds documentation of "firmware-name" to the dt-binding documentation
and switches the driver over to use this.
This commit also makes the driver add a "silead/" prefix to the
firmware name from dt before calling request_firmware. That the
firmware files are stored under /lib/firmware/silead under Linux
is an implementation detail and does not belong in devicetree.

Input: silead_gsl1680 - use "silead/" prefix for firmware loading
The silead touch-controller ICs use a different firmware per digitizer /
tablet model. So there are going to be quite a few of then and they really
should be under a separate subdir.
This commit prefixes the default firmware names with "silead/" just like
we are already doing for devicetree specified firmware names.

Input: silead - add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
As pointed by Hans de Goede, there's no mssl1680 and this is just used in
some ACPI systems to identify the gsl1680 chip. So isn't included in the
OF device ID table since a DT should use the proper device name instead.

If we get ENOENT when trying to load the firmware, this can just mean
that the rootfs is not mounted yet. Return EPROBE_DEFER so the probe
is retried later.
To prevent an infinite probe loop when the firmware does not exist at
all, the retries are capped to 10.

RK8xx PMICs would do real power off in syscore shutdown, if "pm_power_off"
is not assigned(e.g. PSCI is not enabled), we have to provide a dummy
callback for it, otherwise there comes a halt in Reboot system call:
if ((cmd == LINUX_REBOOT_CMD_POWER_OFF) && !pm_power_off)
cmd = LINUX_REBOOT_CMD_HALT;
