Subject: [PATCH v2 0/2] clk: fixed-mmio: Add optional ready registers

From: "Edgar E. Iglesias" <edgar.iglesias@....com>

I'm not sure if this is a good idea but while doing some stuff in emulation
I had a need to wait for a fixed-mmio-clock to go ready before using
devices it drives. I figured it may be useful to have a generic way to
describe a simple polling for readiness.

Cheers,
Edgar

ChangeLog:

v1 -> v2:
* dt-binding: Add unit suffix, ready-timeout -> ready-timeout-us
* example: Remove unused label and renamed to clock@

Edgar E. Iglesias (2):
  dt-bindings: clk: fixed-mmio-clock: Add optional ready reg
  clk: fixed-mmio: Add optional poll for clk readiness
