The previous patch "c5ccf2ad3d33 (Input: synaptics-rmi4 - switch to
reduced reporting mode)" enabled reduced reporting mode unintentionally
on some devices, if the firmware was configured with default Delta X/Y
threshold values. The result unintentionally degrade the performance of
some touchpads.
This patch checks to see that the driver is modifying the delta X/Y
thresholds before modifying the reporting mode.

This laptop (and perhaps other variants of the same model) reports an
SMBus-capable Synaptics touchpad. Everything (including suspend and
resume) works fine when RMI is enabled via the kernel command line, so
let's add it to the whitelist.

The 'axis + 1' calculation is implicit and potentially error prone.
Moreover, few lines before the axis is set explicitly for both X and Y.
Do the same when retrieving different properties for X and Y.

Add support for it by adding compatible and supported chip data
(default settings used).
The chip data on GT9147 is similar to GT912, like
- config data register has 0x8047 address
- config data register max len is 240
- config data checksum has 8-bit

Some devices with a goodix touchscreen have more then 1 capacitive
touch-key. This commit replaces the current support for a single
touch-key, which ignored the reported key-code. With support for
up to 7 touch-keys, based upon checking the key-code which is
post-fixed to any reported touch-data.
KEY_LEFTMETA is assigned to the first touch-key (it will still be
the default keycode for devices with a single touch-key).
KEY_F1, KEY_F2... are assigned as default keycode for the other
touch-keys.
This commit also add supports for keycode remapping, so that
systemd-udev's hwdb can be used to remap the codes to send
keycodes to match the icons on the buttons for devices with more
then 1 touch-key.

The goodix panel sends spurious interrupts after a 'finger up' event,
which always cause a timeout.
We were exiting the interrupt handler by reporting touch_num == 0, but
this was still processed as valid and caused the code to use the
uninitialised point_data, creating spurious key release events.
Report an error from the interrupt handler so as to avoid processing
invalid point_data further.

On some ACPI/x86 devices (where we use one of the ACPI IRQ pin access
methods) the firmware is buggy, it does not properly reset the controller
at boot, and we cannot communicate with it.
Normally on ACPI/x86 devices we do not want to reset the controller at
probe time since in some cases this causes the controller to loose its
configuration and this is loaded into it by the system's firmware.
So on these systems we leave the reset_controller_at_probe flag unset,
even though we have a access to both the IRQ and reset pins and thus
could reset it.
In the case of the buggy firmware we have to reset the controller to
actually be able to talk to it.
This commit adds a special case for this, if the goodix_i2c_test() fails,
and we have not reset the controller yet; and we do have a way to reset
the controller then retry the i2c-test after resetting the controller.
This fixes the driver failing at probe on ACPI/x86 systems with this
firmware bug.

Some devices, e.g the Trekstor Primetab S11B, lose there config over
a suspend/resume cycle (likely the controller loses power during suspend).
This commit reads back the config version on resume and if matches the
expected config version it resets the controller and resends the config
we read back and saved at probe time.

Our goodix_check_cfg_* helpers do things like:
int i, raw_cfg_len = cfg->size - 2;
...
if (check_sum != cfg->data[raw_cfg_len]) {
When cfg->size < 2, this will end up indexing the cfg->data array with
a negative value, which will not end well.
To fix this this commit adds a new GOODIX_CONFIG_MIN_LENGTH define and
adds a minimum size check for firmware-config files using this new define.
For consistency this commit also adds a new GOODIX_CONFIG_GT9X_LENGTH for
the length used for recent gt9xx and gt1xxx chips, instead of using
GOODIX_CONFIG_MAX_LENGTH for this, so that if other length defines get
added in the future it will be clear that the MIN and MAX defines should
contain the min and max values of all the other defines.

Some Apollo Lake (x86, UEFI + ACPI) devices only list the reset GPIO
in their _CRS table and the bit-banging of the IRQ line necessary to

This commit adds support for controlling the IRQ line in this matter,

On most Bay Trail (x86, UEFI + ACPI) devices the ACPI tables do not have
a _DSD with a "daffd814-6eba-4d8c-8a91-bc9bbf4aa301" UUID, adding
"irq-gpios" and "reset-gpios" mappings, so we cannot get the GPIOS by name
without first manually adding mappings ourselves.
These devices contain 2 GpioIo resource in their _CRS table, on all 4 such
devices which I have access to, the order of the 2 GPIOs is reset, int.
Note that the GPIO to which the touchscreen controller irq pin is connected
is configured in direct-irq mode on these Bay Trail devices, the
pinctrl-baytrail.c driver still allows controlling the pin as a GPIO in
this case, but this is not necessarily the case on other X86 ACPI
platforms, nor do we have a guarantee that the GPIO order is the same
elsewhere, so we limit the use of a _CRS table with 2 GpioIo resources
to Bay Trail devices only.

"irq-gpios" and "reset-gpios" mappings, so we cannot get the GPIOS by name
without first manually adding mappings ourselves.
These devices contain 1 GpioInt and 1 GpioIo resource in their _CRS table:
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (RBUF, ResourceTemplate ()
{
I2cSerialBusV2 (0x0014, ControllerInitiated, 0x00061A80,
AddressingMode7Bit, "\\_SB.PCI0.I2C2",
0x00, ResourceConsumer, , Exclusive,
)
GpioInt (Edge, ActiveLow, Shared, PullDefault, 0x0000,
"\\_SB.GPO1", 0x00, ResourceConsumer, ,
)
{ // Pin list
0x0013
}
GpioIo (Shared, PullDefault, 0x0000, 0x0000,
IoRestrictionOutputOnly,

)
{ // Pin list

})
Return (RBUF) /* \_SB_.PCI0.I2C2.TCS1._CRS.RBUF */
}
There is no fixed order for these 2. This commit adds code to check that
there is 1 of each as expected and then registers a mapping matching their
order using devm_acpi_dev_add_driver_gpios().
This gives us access to both GPIOs allowing us to properly suspend the
controller during suspend, and making it possible to reset the controller
if necessary.

GPIO setup
Before this commit we would always reset the controller at probe when we
have access to the GPIOs which are necessary to do a reset.
Doing the reset requires access to the GPIOs, but just because we have
access to the GPIOs does not mean that we should always reset the
controller at probe. On X86 ACPI platforms the BIOS / UEFI firmware will
already have reset the controller and it will have loaded the device
specific config into the controller. Doing the reset sometimes causes the
controller to lose its configuration, so on X86 ACPI platforms this is not
a good idea.
This commit adds a new reset_controller_at_probe boolean to control the
reset at probe behavior.
This commits sets the new bool to true when we set irq_pin_access_method
to IRQ_PIN_ACCESS_GPIO, so there are no functional changes.

setup
At least on X86 ACPI platforms it is not necessary to load the touchscreen
controller config from disk, if it needs to be loaded this has already been
done by the BIOS / UEFI firmware.
Even on other (e.g. devicetree) platforms the config-loading as currently
done has the issue that the loaded cfg file is based on the controller
model, but the actual cfg is device specific, so the cfg files are not
part of linux-firmware and this can only work with a device specific OS
image which includes the cfg file.
And we do not need access to the GPIOs at all to load the config, if we
do not have access we can still load the config.
So all in all tying the decision to try to load the config from disk to
being able to access the GPIOs is not desirable. This commit adds a new
load_cfg_from_disk boolean to control the firmware loading instead.
This commits sets the new bool to true when we set irq_pin_access_method
to IRQ_PIN_ACCESS_GPIO, so there are no functional changes.

Suspending Goodix touchscreens requires changing the interrupt pin to
output before sending them a power-down command. Followed by wiggling
the interrupt pin to wake the device up, after which it is put back
in input mode.
So far we have only effectively supported this on devices which use
devicetree. On X86 ACPI platforms both looking up the pins; and using a
pin as both IRQ and GPIO is a bit more complicated. E.g. on some devices
we cannot directly access the IRQ pin as GPIO and we need to call ACPI
methods to control it instead.
This commit adds a new irq_pin_access_method field to the goodix_chip_data
struct and adds goodix_irq_direction_output and goodix_irq_direction_input
helpers which together abstract the GPIO accesses to the IRQ pin.
This is a preparation patch for adding support for properly suspending the
touchscreen on X86 ACPI platforms.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
This issue was found with the help of Coccinelle.

In striding RQ mode, the buffers of an RX WQE are first
prepared and posted to the HW using a UMR WQEs via the ICOSQ.
We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not

- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

When resetting the RQ (moving RQ state from RST to RDY), the driver
resets the WQ's SW metadata.
In striding RQ mode, we maintain a field that reflects the actual
expected WQ head (including in progress WQEs posted to the ICOSQ).
It was mistakenly not reset together with the WQ. Fix this here.

Add number of WQEBBs (WQE's Basic Block) to WQE info struct. Set the
number of WQEBBs on WQE post, and increment the consumer counter (cc)
on completion.
In case of error completions, the cc was mistakenly not incremented,
keeping a gap between cc and pc (producer counter). This failed the
recovery flow on the ICOSQ from a CQE error which timed-out waiting for
the cc and pc to meet.

Nvidia card may come with a "phantom" UCSI device, and its driver gets
stuck in probe routine, prevents any system PM operations like suspend.
There's an unaccounted case that the target time can equal to jiffies in
gpu_i2c_check_status(), let's solve that by using readl_poll_timeout()
instead of jiffies comparison functions.

There are few maximum bus frequencies being used in the I²C core code.
Provide generic definitions for bus frequencies and use them in the core.
The drivers may use predefined constants where it is appropriate.
Some of them are already using these under slightly different names.
We will convert them later to use newly introduced defines.
Note, the name of modes are chosen to follow well established naming
scheme [1].
These definitions will also help to avoid typos in the numbers that
may lead to subtle errors.
