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!

Yours,
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.

----------------------------------------------------------------
Linus Walleij (8):
      bus: ixp4xx: Add DT bindings for the IXP4xx expansion bus
      bus: ixp4xx: Add a driver for IXP4xx expansion bus
      watchdog: ixp4xx: Rewrite driver to use core
      pata: ixp4xx: Use local dev variable
      pata: ixp4xx: Use IS_ENABLED() to determine endianness
      pata: ixp4xx: Refer to cmd and ctl rather than csN
      pata: ixp4xx: Add DT bindings
      pata: ixp4xx: Rewrite to use device tree
