The HDMI vpll clock should be enabled when bind() is called. So move the
clk_prepare_enable of that clock to bind() function and add the missing
clk_disable_unprepare() required in error handling path and unbind().

In bind the clk_prepare_enable of the HDMI pclk is called before adding the
i2c_adapter. So it should be the other way around in unbind, first remove
the i2c_adapter and then call the clk_disable_unprepare.

The __send_and_alloc_skb() receives a skb ptr as a parameter but in
case it fails the skb is not valid:
- Send failed and released the skb internally.
- Allocation failed.
The current code tries to release the skb in case of failure which
causes redundant freeing.

This removes a dependency on the order options are passed when creating
a fabrics controller. With the old code, if "nr_io_queues" appears before
an "nqn" option specifying the discovery controller, then nr_io_queues
is overridden with zero. If "nr_io_queues" appears after specifying the
discovery controller, then the nr_io_queues option is used to set the
number of queues, and the driver attempts to establish IO connections
to the discovery controller (which doesn't work).
It seems better to ignore (and warn about) the "nr_io_queues" option
if userspace has already asked to connect to the discovery controller.

This fixes hangs with legacy applications that use the mmap() syscall on
the fbdev device to map framebuffer memory. The fbdev implementation for
mmap() creates a mapping that conflicts with DRM usage and causes a hang
when the memory is accessed through the mapping.

Driver uses alias from Device Tree as an index of pin controller data
array. In case of a wrong DTB or an out-of-tree DTB, the alias could be
outside of this data array leading to out-of-bounds access.
Depending on binary and memory layout, this could be handled properly
(showing error like "samsung-pinctrl 3860000.pinctrl: driver data not
available") or could lead to exceptions.

When adding GP-1-28 port pin support it was forgotten to remove the
CLKOUT pin from the list of pins that are not associated with a GPIO
port in pinmux_pins[]. This results in a warning when reading the
pinctrl files in sysfs as the CLKOUT pin is still added as a none GPIO
pin. Fix this by removing the duplicated entry which is no longer
needed.

With the introduction of asymmetric slices in CNL, we cannot rely on
the previous SUBSLICE_MASK getparam to tell userspace what subslices
are available. Here we introduce a more detailed way of querying the
Gen's GPU topology that doesn't aggregate numbers.
This is essential for monitoring parts of the GPU with the OA unit,
because counters need to be normalized to the number of
EUs/subslices/slices. The current aggregated numbers like EU_TOTAL do
not gives us sufficient information.
The Mesa series making use of this API is :

As a bonus we can draw representations of the GPU :

There are a number of information that are readable from hardware
registers and that we would like to make accessible to userspace. One
particular example is the topology of the execution units (how are
execution units grouped in subslices and slices and also which ones
have been fused off for die recovery).
At the moment the GET_PARAM ioctl covers some basic needs, but
generally is only able to return a single value for each defined
parameter. This is a bit problematic with topology descriptions which
are array/maps of available units.
This change introduces a new ioctl that can deal with requests to fill
structures of potentially variable lengths. The user is expected fill
a query with length fields set at 0 on the first call, the kernel then
sets the length fields to the their expected values. A second call to
the kernel with length fields at their expected values will trigger a
copy of the data to the pointed memory locations.
The scope of this uAPI is only to provide information to userspace,
not to allow configuration of the device.

not supported.

Up to now, subslice mask was assumed to be uniform across slices. But

This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which
caused the following issues:
1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.
The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed
rmi4_smbus 7-002c: failed to get SMBus version number!
rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask.

rmi4_physical rmi4-00: Failed to suspend functions: -16
rmi4_smbus 7-002c: Failed to resume device: -16

rmi4_physical rmi4-00: rmi_driver_clear_irq_bits: Failed to change enabled interrupts!
rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts!
psmouse: probe of serio3 failed with error -1
2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.
Analysis form Richard Schütz:
"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."
The affected devices often show:
i801_smbus 0000:00:1f.4: BIOS is accessing SMBus registers
i801_smbus 0000:00:1f.4: Driver SMBus register access inhibited

We were previously selecting 1024x768 and 32BPP as the default
set-up for the PL111 consumers.
This does not work on elder systems: the device tree bindings
support a property "max-memory-bandwidth" in bytes/second that
states that if you exceed this the memory bus will saturate.
The result is flickering and unstable images.
Parse the "max-memory-bandwidth" and respect it when
intializing the driver. On the RealView PB11MP, Versatile and
Integrator/CP we get a nice console as default with this code.

Prior to 25520d55cdb6 ("block: Inline blk_integrity in struct gendisk")
we needed to temporarily add a zero-capacity disk before registering for
blk-integrity. But adding a zero-capacity disk caused the partition
table scanning to bail early, and this resulted in partitions not coming
up after a probe of the BTT or blk namespaces.
We can now register for integrity before the disk has been added, and
this fixes the rescan problems.

The following happens when connection a DVI output driven
from the SiI9022 using a DVI-to-VGA adapter plug:
i2c i2c-0: sendbytes: NAK bailout.
i2c i2c-0: sendbytes: NAK bailout.
Then no picture. Apparently the I2C engine inside the SiI9022
is not smart enough to try to fall back to DDC I2C. Or the
vendor have not integrated the electronics properly. I don't
know which one it is.
After this, the I2C bus seems stalled and the first attempt to
read the status register fails, and the code returns with
negative return value, and the display fails to initialized.
Instead, retry status readout five times and continue even
if this fails.
Tested on the ARM Versatile Express with a DVI-to-VGA
connector, it now gives picture.
Introduce a helper struct device *dev variable to make
the code more readable.

We want to cut down the default bpp to 16 on the RealView so
we can have a 1024x768 framebuffer console by default. The
memory bandwidth limitations makes this not work with the
PL111 default of 32bpp.
This builds on top of the earlier patches making the
framebuffer default bpp a per-variant variable.

The PL110, Integrator and Versatile boards strongly prefer to
use 16 BPP even if other modes are supported, both to keep down
memory consumption and also to easier find a good match to
supported resolutions with consideration taken to the memory
bandwidth of the platforms.

HW Engineer's Notes:
During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
VGA_TEST_ENABLE, to leave it in the same state as before.

While checking plane states for updates during atomic check, we create
dc_plane_states in preparation. These dc states should be freed if
something errors.
Although the input transfer function is also freed by
dc_plane_state_release(), we should free it (on error) under the same
scope as where it is created.
