This converts the lms283gf05 backlight driver to use GPIO
descriptors and switches the single PXA Palm Z2 device
over to defining these.
Since the platform data was only used to convey GPIO
information we can delete the platform data header.
Notice that we define the proper active low semantics i
The comment says the layout and options use 8 bits, and the shift
uses 8 bits. However the mask is 0xf, ie. 0b (4 bits).
This could be surprising when introducing new layouts or options
that take more than 4 bits, as this would silently drop the high
bits.
Make the masks consistent with t
This patchset aims to lay down some prep work before configfs can be
implemented for the vkms driver. The first patch in the series adds a
new type vkms_config to track device configuration. The second and third
patch add module testing support for writeback operations.
The first patch is develope
Currently, data for the device instance is held by vkms_device.
Add a separate type, vkms_config to contain configuration details
for the device and various modes to be later used by configfs.
This config data stays constant once the device is created.
Accordingly, add vkms_create and vkms_destroy
Add enable_writeback feature to vkms_config as a module.

I can't stand memory leak, i will revert "Revert "drm/amd/display: Fix memory
leaks in S3 resume""
revert 5efc1f4b454c6179d35e7b0c3eda0ad5763a00fc in today linux 5.11-rc3.
i use rc kernel every week.
Hi folks,
today I joined to testing Kernel 5.11 and saw that the kernel log was
flooded with BUG messages:

The schematics shows the GKTW70SDAD1SD panel in the J4 connector, not
the LVDS J7 connector.

Hi all,
After merging the amdgpu tree, today's linux-next build (htmldocs)
produced these warnings:
drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h:340: warning: Incorrect use
of kernel-doc format: * @active_vblank_irq_count

The out of tree vendor driver was recently updated to support the
ast2400 and ast2600. These patches begin to add that support to the
mainline driver.
With these two cleanups it should be easier to support different
families of BMC system on chip with this driver.
I will merge them through drm-mi
This scales better to multiple families of SoC. The lookup by compatible
can be removed in a future change.

There are minor differences in the values for the threshold value and
the scan line size between families of ASPEED SoC. Additionally the SCU
register for the output control differs between families.
This adds device tree matching to parameterise these values, allowing us
to add support for the AS

When AST2500 acts as stand-alone VGA so that DRAM and DVO initialization
have to be achieved by VGA driver with P2A (PCI to AHB) enabling.
However, HW suggests disable Fast reset mode after DRAM initializaton,
because fast reset mode is mainly designed for ARM ICE debugger.
