Hi,
This series aims to add MIPI DSI support for Freescale i.MX93 SoC.
There is a Synopsys DesignWare MIPI DSI host controller and a Synopsys
Designware MIPI DPHY embedded in i.MX93. Some configurations and
extensions to them are controlled by i.MX93 media blk-ctrl.
Add a DRM bridge for i.MX93
Add dw_mipi_dsi_get_bridge() helper so that it can be used by vendor
drivers which implement vendor specific extensions to Synopsys DW MIPI DSI.

Introduce ->get_input_bus_fmts() callback to struct dw_mipi_dsi_plat_data
so that vendor drivers can implement specific methods to get input bus
formats for Synopsys DW MIPI DSI.
While at it, implement a generic callback for ->atomic_get_input_bus_fmts(),
where we try to get the input bus formats
The DATAEN_ACTIVE_LOW bit in DSI_DPI_CFG_POL register is set to zero,
so set the DRM_BUS_FLAG_DE_HIGH flag in input_bus_cfg.flags. It appears
that the DRM_BUS_FLAG_PIXDATA_SAMPLE_NEGEDGE flag also makes sense, so
set it in input_bus_cfg.flags too. With this patch, the flags set by

Vendor drivers may need to fixup mode due to pixel clock tree limitation,
so introduce the ->mode_fixup() callcack to struct dw_mipi_dsi_plat_data
and call it at atomic check stage if available.

To get better accuration, use pixel clock rate to calculate lbcc instead of
lane_mbps since the pixel clock rate is in KHz while lane_mbps is in MHz.

When multiple displays are connected to the same SPI bus, the data/command
switch is sometimes considered part of the bus and is shared among the
displays.
This series adds the GPIO_FLAGS_BIT_NONEXCLUSIVE flag for this GPIO and
SPI bus locking to the panel-mipi-dbi/drm_mipi_dbi drivers to support
Multiple displays may be connected to the same bus and share a D/C GPIO,
so the display driver needs exclusive access to the bus to ensure that
it can control the D/C GPIO safely.

Recently two patches [1] [2] have hit a case of mistakenly picking
an IOCTL number which was already in-use. This is hard to debug
because the last definition wins and there is no indication that
there is a conflict.
Fix this by enabling -Werror=override-init for the IOCTL table.

Since v6.5-rc1, kunit gained a devm/drmm-like mechanism that makes tests
resources much easier to cleanup.
This series converts the existing tests to use those new actions where

As we gain more tests, boilerplate to allocate an atomic state and free
it starts to be there more and more as well.
In order to reduce the allocation boilerplate, we can create a helper

This will also clean up the exit path.
The *_mock_device functions allocate a DRM device that needs to be
released using drm_dev_unregister.
Now that we have a kunit release action API, we can switch to it and
don't require any kind of garbage collection from the caller.

Now that we have a helper that takes care of an atomic state allocation
and cleanup, we can migrate to it to simplify our tests.

Calling drm_kunit_helper_free_device() to clean up the resources
allocated by drm_kunit_helper_alloc_device() is now optional and not
needed in most cases.
Remove it.

We've had a couple of tests that weren't really obvious, nor did they
document what they were supposed to test. Document that to make it
hopefully more obvious.

Separate these two things into two different patches.
per suggestio
This patch solves two problem:
First, when we suspended guest VM, it called into Qemu to call
virtio_reset->__virtio_queue_reset, this cleared all virtuqueue
information of virtgpu on Qemu end. As a result, after guest
resumed, guest sended ctrl/cursor requests to Qemu through
virtqueue, but Qemu

Hi all,
Thanks for Gerd Hoffmann's advice. V3 makes below changes:
* Use enum for freeze mode, so this can be extended with more
modes in the future.
* Rename functions and paratemers with "_S3" postfix.
And no functional changes.
Best regards,
Jiqian Chen.

Some of the patches are needed to be backported to v5.8 so I wonder if
you should do the refactoring later in the series.
I guess best way is to check if you can apply the series in v5.8

There are two problems in lsdc_pixel_pll_setup()
1. If kzalloc() fails then call iounmap() to release the resources.
2. Both kzalloc and ioremap doesnot return error pointers on failure, so
using IS_ERR_OR_NULL() checks is a bit confusing and not very right,
fix this by changing those to NULL

After the commit in the Fixes: line below, HPD polling stopped working
on i915, since after that change calling drm_kms_helper_poll_enable()
doesn't restart drm_mode_config::output_poll_work if the work was
stopped (no connectors needing polling) and enabling polling for a
connector (during runtime
Add a helper to reschedule drm_mode_config::output_poll_work after
polling has been enabled for a connector (and needing a reschedule,
since previously polling was disabled for all connectors and hence
output_poll_work was not running).
This is needed by the next patch fixing HPD polling on i915.
