Subject: [GIT PULL] i2c-host for v6.20
Hi Wolfram,
here is the pull request for the merge window. Most of the
patches that did not make it were not ready to be merged due to
missing or pending reviews. Some were ready only very late and I
did not feel comfortable including them. For a smaller set I
simply ran out of time to follow up properly.
This pull request includes general cleanups across several
drivers, a DesignWare core refactoring to enable mode switching,
runtime PM improvements for imx-lpi2c, a new lan9691 I2C driver
and targeted fixes in rtl9300, spacemit and tegra.
I will try to collect a few more minor patches for next week, so
if it is OK with you, please expect a second part.
Thank you and I wish you a great weekend,
Andi
