I would love to see a second nic implementation; this patch set and
overall design is driven by GVE limitations.

This patch changes drm_mode_legacy_fb_format() to only return formats
which are supported by the current drm-device. The motivation for this
change is to fix a regression introduced by commit
c91acda3a380 ("drm/gem: Check for valid formats") which stops the Xorg
modesetting driver from working on
This is a general driver for LM3509 backlight chip of TI.
LM3509 is High Efficiency Boost for White LEDs and/or OLED Displays with
Dual Current Sinks. This driver supports OLED/White LED select, brightness
control and sub/main control.

Allow the dclk to reset its rate when a rate change is initiated from an

When the Allwinner A64's TCON0 searches the ideal rate for the connected

which PLL-MIPI does not support.
This happens for example on the Olimex TERES-I laptop where TCON0

The Allwinner SoC's typically have an upper and lower limit for their
clocks' rates. Up until now, support for that has been implemented
separately for each clock type.
Implement that functionality in the sunxi-ng's common part making use of
the CCF rate liming capabilities, so that it is
On some pinephones the video output sometimes freezes (flips between two
frames) [1]. It seems to be that the reason for this behaviour is that
PLL-MIPI is outside its limits, and the GPU is not running at a fixed
rate.

Hi Jonathan,
Here's the final-er version of the IIO DMABUF patchset.
This v9 fixes the few issues reported by the kernel bot.
This was based on next-20240308.
Changelog:

- Select DMA_SHARED_BUFFER in Kconfig
- Remove useless forward declaration of 'iio_dma_fence'
- Import
