Add an I2C bus driver for virtio para-virtualization.
The controller can be emulated by the backend driver in
any device model software by following the virtio protocol.
This driver communicates with the backend driver through a
virtio I2C message structure which includes following parts:
-
POSIX specifies that the first field of the supplied msgp, namely mtype,
is a long, not a __kernel_long_t, and it's a user-defined struct due to
the variable-length mtext field so we can't even bend the spec and make
it a __kernel_long_t even if we wanted to. Thus we must use the compat
syscalls

KSEG1ADDR should rewrite the memory address
make dtbs_check report a warning because the documentation
for the A64 codec compatible is missing.
The A64 codec compatible is actually a simple fallback to the A33.

Like A83T the Allwinner H3 doesn't have the DMA reception available for
some audio interfaces.
As it's already documented for A83T convert this to an enum and add the H3
interface.

Adding a note to update this thread: the v5.9 tree now has
033b5d775511 ("mm/khugepaged: fix filemap page_to_pgoff(page) != offset")
which fixes this VM_BUG_ON_PAGE (or data corruption) when CONFIG_NUMA
is not set: we are hoping that may have have been the problem here.
Checkpatch script produces warning:
WARNING: function definition argument 'const struct sun4i_i2s *'
should also have an identifier name.
Let's fix this by adding identifier name to get_bclk_parent_rate()
and set_fmt() callback definition.

The FIFO TX reg is volatile and sun8i i2s register
mapping is different from sun4i.
Even if in this case it's doesn't create an issue,
Avoid setting some regs that are undefined in sun8i.

As slots and slot_width can be set manually using set_tdm().
These values are then kept in sun4i_i2s struct.
So we need to check if these values are set or not.
This is not done actually and will trigger a bug.
For example, if we set to the simple soundcard in the device-tree

Because SUN4I_I2S_FIFO_CTRL_REG is volatile, writes done while the

Hi,
Just some minor changes compare to v6.
As explain in v6 there is no more HDMI soundcard,
I will try to introduce a dedicated Allwinner soundcard

Hi folks!
I have a question.
What happens when dd writes data to a missing device?
For example:
# dd

Today I and wrongly entered /dev/adb instead of /dev/sdb,
