This driver adds support for Silead touchscreens. It has been tested
with GSL1680 and GSL3680 touch panels.
It supports ACPI and device tree enumeration. Screen resolution,
the maximum number of fingers supported and firmware name are
configurable.

Input: silead - remove some dead code
buf[0] is an unsigned char. touch_nr is an int. The test for negative
here doesn't make sense so I have removed it.

Input: silead - use devm_gpiod_get
The silead code is using devm_foo for everything (and does not free
any resources). Except that it is using gpiod_get instead of
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.

Input: silead: retry firmware load
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.

Evb is part of a family of boards called rk3399pro. As best as possible, the
properties shared by the rk3399pro family are placed in rk3399pro.dtsi, while
Evb-linux specific bits are in rk3399pro-evb-v11-linux.dts. This does not add full
support for the base Evb board.
Working and tested (to some extent):
* cluster cpu/gpu support -- including frequency, performance
* UART / console
* Thermal
* Touchscreen
* EDP
* Wifi
* Bluetooth / Webcam
* SD card
* eMMC
* USB2/USB3
* Backlight
* DVFS: included cpu/gpu/ddr
* CAMERA: had tested the ov13850 camera
* VIDEO: tested the h264 video source
* AUDIO: play and mic music
* NPU
* HDMI
* GMAC
Not tested:
* Pcie
* MIPI
Not working:
* SD CARD: no sure, maybe the board sd card is broken by hardware.

Added this patch to support the v10 board before, as the most people used
the rk3399pro v11 board for now.
Note: this patch had *not* verified the all functions, it can bringup for
v10 board and some basic functions.
(included wifi/bt, camera, display, video, usb...and so on.)

On some xHCI controllers (e.g. Rockchip RK3399/RK3328/RK1808),
which are integrated in DWC3 IP, need to enable the Evaluate
Next TRB(ENT) flag in the TRB data structure to force xHC to
pre-fetch the next TRB of a TD. It's useful for the stability
of xHCI when transfer large data.
I have verify this patch on the following three cases:
Case 1:
On RK3399/RK3399Pro platforms, I found that when USB 3.0
read/write at the same time in the following test case,
it may easily fail without this patch.
Host transfer: 1024B, 4MB, 4MB, 4MB
Device transfer: 1024B, 4MB, 4MB, 4MB
Both Host and Device transfer "24B, 4MB, 4MB, 4M" Repeatedly
until transfer fail.
Case 2:
On RK3399 platform, Type-C1 USB 3.0 port connects with HUB
and Orbbec USB 3.0 Camera with the enumeration information:
usb 5-1: new high-speed USB device number 2 using xhci-hcd
usb 5-1: New USB device found, idVendor=05e3, idProduct=0610

usb 6-1.2: Product: Orbbec(R) Astra(TM)
usb 6-1.2: Manufacturer: Orbbec(R)
Without this patch, it's possible to fail to open the Orbbec USB 3.0
camera or fail to preview image.
Case3:
On RK3399Pro platform, transfer the NPU data between the NPU USB 3.0
device and RK3399 USB 3.0 host.

The rockchip saradc controller is too scanty for some products that is
requires at least x10 channels ADC. Generally, we can use a CMOS analog
switch to extend a multi-channel ADC, eg.sgm3699. It's a quad,
bidirectional, single-pole/double-throw (SPDT) CMOS analog siwtch.
This patch implements a multiplexer ADC controller using a number of
gpio pins and parent ADC channel. It's compatible with most of CMOS
analog switch. And it provides a direct mode to get a raw data of each
muxadc channel.

{64,32}-bit systems
Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

On the raspberry pi, we might have two lirc devices; one for sending and
one for receiving. This change makes it much more apparent which one
is which.

Since commit a60d64b15c20 ("media: lirc: lirc interface should not be
a raw decoder"), the message in the documentation is incorrect as the
module name is rc_core, not lirc_dev. Since the message is not useful,
just make the message debug and remove it from the documentation.

The semantics for lirc IR transmit with raw IR is that the write call
should block until the IR is transmitted. Some drivers have no idea
when this actually is (e.g. mceusb), so there is a wait.
This is useful for userspace, as it might want to send a IR button press,
a gap of a predefined number of milliseconds, and then send a repeat
message.
It turns out that for transmitting scancodes this feature is even more
useful, as user space has no idea how long the IR is. So, maintain
the existing semantics for IR scancode transmit.

LIRCCODE is a lirc mode where a driver produces driver-dependent
codes for receive and transmit. No driver uses this any more. The
LIRC_GET_LENGTH ioctl was used for this mode only.

For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.
In addition, we need to know the specific variant of the protocol.
In short, these changes are made to the wakeup_protocols sysfs entry:
- list all the protocol variants rather than the protocol groups,
e.g. "nec nec-x nec-32" rather than just "nec".
- only allow one protocol variant to be selected rather than multiple
- wakeup_filter can only be set once a protocol has been selected in
wakeup_protocols.
This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.
