Subject: [PATCH 1/3 v2] powerpc/fsl: Use new clockgen binding

From: Scott Wood <[email protected]>

The driver retains compatibility with old device trees, but we don't
want the old nodes lying around to be copied, or used as a reference
(some of the mux options are incorrect), or even just being clutter.

We will also need the #clock-cells in the clockgen node in order to
add fman nodes.

- * "fsl,qoriq-core-mux-2.0" for core mux clocks (v2.0)

Subject: [PATCH 3/3 v2] clk: qoriq: update clock driver

From: Yuantian Tang <[email protected]>

Legacy bindings are deleted. So the legacy support in driver
can be deleted safely.
Add more chip-specific compatible as well to support more Socs.

The comment about #clock-cells is no longer relevant to this patch, since that
has already been added.

NACK (both this and 2/3). The legacy support is intended to preserve
compatibility, regardless of what the dts files in the current kernel tree do.
If years later we find it's been broken for a while and nobody complained,
then maybe it'll be time to remove it, but why deliberately throw away
compatibility the instant the users have been removed from reference DTs that
might be copied by board vendors, etc?

Note that even if we didn't care about long-term compatibility at all,
removing the support in the same patchset as the change to the dts files means
that the patches can't go in via separate trees (though if that's still the
intent, you should make it clear who you're asking to take what by putting
them in separate patchsets).

I'm a bit confused by this series. Normally you want to update the dts
files first and wait some period of time before removing driver support
(and bindings).
