Pull drm updates from Dave Airlie:
"Highlights:

- i915 has seen a lot of refactoring and uAPI cleanups due to a
change in the upstream direction going forward

This has all been audited with known userspace, but there may be
some pitfalls that were missed.

- i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

- i915 enables Jasper and Elkhart Lake by default and has preliminary
XeHP/DG2 support

- amdgpu adds support for Cyan Skillfish

- lots of implicit fencing rules documented and fixed up in drivers

- msm now uses the core scheduler

- the irq midlayer has been removed for non-legacy drivers

- the sysfb code now works on more than x86.

refactorings.

drm/amdgpu: Optimize EEPROM RAS table I/O

Split functionality between read and write, which
simplifies the code and exposes areas of
optimization and more or less complexity, and take
advantage of that.

Read and write the table in one go; use a separate
stage to decode or encode the data, as opposed to
on the fly, which keeps the I2C bus busy. Use a
single read/write to read/write the table or at
most two if the number of records we're
reading/writing wraps around.

Check the check-sum of a table in EEPROM on init.

Update the checksum at the same time as when
updating the table header signature, when the
threshold was increased on boot.

Take advantage of arithmetic modulo 256, that is,
use a byte!, to greatly simplify checksum
arithmetic.

drm/amdgpu: I2C EEPROM full memory addressing

* "eeprom_addr" is now 32-bit wide.
* Remove "slave_addr" from the I2C EEPROM driver
interface. The I2C EEPROM Device Type Identifier
is fixed at 1010b, and the rest of the bits
of the Device Address Byte/Device Select Code,
are memory address bits, where the first three
of those bits are the hardware selection bits.
All this is now a 19-bit address and passed
as "eeprom_addr". This abstracts the I2C bus
for EEPROM devices for this I2C EEPROM driver.
Now clients only pass the 19-bit EEPROM memory
address, to the I2C EEPROM driver, as the 32-bit
"eeprom_addr", from which they want to read from
or write to.
