Currently, operations related to irq/msi in Hyper-V vPCI are

For now there are 3 ways to promote the pinned_page_dirty_scope

1. Through vfio pin interface.
2. Detach a group without pinned_dirty_scope.
3. Attach a group with pinned_dirty_scope.

When we want to promote the pinned_page_dirty_scope of vfio_iommu,
we call the "update" function to visit all vfio_group, but when we
want to downgrade this, we can set the flag as false directly.
So we'd better make an explicit "promote" semantic to the "update"
function. BTW, if vfio_iommu
The pinned_scope of external domain's groups are always true, that's
to say we can safely ignore external domain when promote pinned_scope

Building with the Clang assembler shows the following warning:

offset 0x16
The Clang assembler strips section symbols. That ends up giving
objtool's find_func_containing() much more test coverage than normal.

GPIO CDEV is now optional and required for the selftests so add it to
the config.

Initially I just wanted to port the selftests to the latest GPIO uAPI,
but on finding that, due to dependency issues, the selftests are not built
for the buildroot environments that I do most of my GPIO testing in, I
decided to take a closer look.
The first patch is essentially a rewrite of the

The print format of this parameter does not match, because it is defined
as int type, so modify the matching format of this parameter to %d format.

The purpose of SVS is to help find the suitable voltages
for DVFS. Therefore, if SVS bank voltages are concerned
to be wrong, we can adjust SVS bank voltages by this patch.

The Smart Voltage Scaling(SVS) engine is a piece of hardware
which calculates suitable SVS bank voltages to OPP voltage table.
Then, DVFS driver could apply those SVS bank voltages to PMIC/Buck
when receiving OPP_EVENT_ADJUST_VOLTAGE.

1. SVS driver uses OPP adjust event in [1] to update OPP table voltage part.
2. SVS driver gets thermal/GPU device by node [2][3] and CPU device by
get_cpu_device(). After retrieving subsys device, SVS driver does
device_link_add() to make sure probe/suspend callback priority.
3. SVS dts refers to

It turned out(Maxime suggestion) that bit 26 of SUN4I_TCON0_IO_POL_REG is
dedicated to invert DCLK polarity and this makes thing really easier than
before. So let's handle DCLK polarity by adding
SUN4I_TCON0_IO_POL_DCLK_POSITIVE as bit 26 and activating according to

During commit 88bc4178568b ("drm: Use new
DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_*
macros have been changed to avoid ambiguity but just because of this
ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning
_SAMPLE_ not _DRIVE_.

First patch is a tested by me fix, while the second need testing to
understand if it works correctly with any sunxi SoC with DE peripheral.
Already tested SoCs are:
- A20
- A33
Need testing:
- A10
- A10s
- A13

Fix kernel-doc notation for 2 functions so that the generated
html is correct. Currently it skips all text between the
':' and the '-', so "[un]register a clock rate" is missing.
