[PATCH 00/27] Renesas CMT (Compare Match Timer) DT bindings

[Laurent Pinchart]

Hello,

This patch set adds DT support to the Renesas CMT driver.

The first 14 patches are a bunch of necessary cleanups that reorganize the
driver, its platform data, and the memory, interrupt and clock resources it
expects. As a result the driver accepts a new platform data model close to the
hardware with supports for all the timer channels using a single device.

The next 7 patches (15 to 21) move all platforms from the old to the new
platform data model. Patch 22 then drops support for the old model, and patch
23 finally adds DT support.

Patches 24 to 27 then add the CMT devices to the r8a7790 and r8a7791 device
trees, and enable them for the lager-reference and koelsch-reference boards.

The patches are based on top of Simon's latest devel branch with the
"[PATCH v4 0/2] [RESEND] Lager and Koelsch reference serial port support"
series applied.
