710b65335c i2c: parport-light: remove driver
The justification of a light version of the parport driver was less
overhead for embedded systems. Well, today, even if an embedded system
still has a parport, it surely can handle the fully-fledged parport
driver. Remove it to reduce the maintenance burden.

937d6eefc7 Here's the main documentation changes for 5.5:
- Various kerneldoc script enhancements.
 
  - More RST conversions; those are slowing down as we run out of things to
    convert, but we're a ways from done still.
 
  - Dan's "maintainer profile entry" work landed at last.  Now we just need
    to get maintainers to fill in the profiles...
 
  - A reworking of the parallel build setup to work better with a variety of
    systems (and to not take over huge systems entirely in particular).
 
  - The MAINTAINERS file is now converted to RST during the build.
    Hopefully nobody ever tries to print this thing, or they will need to
    load a lot of paper.
 
  - A script and documentation making it easy for maintainers to add Link:
    tags at commit time.
 
 Also included is the removal of a bunch of spurious CR characters.

thus replace PCH with SOC where it appropriate.

529766e0a0 i2c: Add drivers for the AMD PCIe MP2 I2C controller
MP2 controllers have two separate busses, so may accommodate up to two I2C
adapters. Those adapters are listed in the ACPI namespace with the
"AMDI0011" HID, and probed by a platform driver.

Communication with the MP2 takes place through MMIO registers, or through
DMA for more than 32 bytes transfers.

This is major rework of the patch submitted by Nehal-bakulchandra Shah from
AMD (https://patchwork.kernel.org/patch/10597369/).

Most of the event handling of v3 was rewritten to make it work with more
than one bus (e.g on Ryzen-based Lenovo Yoga 530), and this version
contains many other improvements.

98f486f18d Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
 - new drivers: Kontron PLD, Wondermedia VT
 - mv64xxx driver gained sun4i support and a bigger cleanup
 - duplicate driver 'intel-mid' removed
 - added generic device tree binding for sda holding time (and
   designware driver already uses it)
 - we tried to allow driver probing with only device tree and no i2c
   ids, but I had to revert it because of side effects.  Needs some
   rethinking.
 - driver bugfixes, cleanups...
