Hi SoC maintainers,
this is a set of combined driver updates for IXP4xx targeted for the
v5.15 merge window.
I am sending it to the SoC tree because of the cross-subsystem
dependencies and since the corresponding DTS changes goes
into SoC. These will be sent separately.
Note the following:
All new DT bindings in this patch set are ACKed by bindings
maintainer Rob Herring.
The new expansion bus driver goes in through the SoC tree as is
custom for bus drivers.
The watchdog maintainer has ACKed the watchdog patch, which
also briefly affects the timer driver.
The PATA changes also have some mach dependencies.
I have informed the libata maintainer that I intend to take these
through ARM SoC.

Please pull it in!

Linus Walleij

pata: ixp4xx: Rewrite to use device tree (2021-08-04 12:20:44 +0200)
----------------------------------------------------------------
IXP4xx driver updates for modernizing the IXP4xx platforms,
taregeted for v5.15:
- Add DT bindings to the expansion bus and PATA libata driver.
- Add a new expansion bus driver.
- Rewrite the watchdog driver to use the watchdog core and
spawn from the timer (clocksource) driver.
- Refactor the PATA/libata driver to probe from the device
tree and use the expansion bus driver to manipulate chip
select timings directly.
----------------------------------------------------------------
