[PATCH v6 1/9] clk: bcm: kona: Move CLOCK_COUNT defines into the driver

From: Artur Weber <aweber.kernel@gmail.com>
Date: 2025-08-13 11:00:20
Also in: linux-clk, linux-devicetree, lkml
Subsystem: common clk framework, the rest · Maintainers: Michael Turquette, Stephen Boyd, Linus Torvalds

CLOCK_COUNT defines for each CCU are stored in the DT binding header.
This is not correct - they are not used by device trees, only internally
by the driver.

Move the CLOCK_COUNT defines directly into the driver in preparation
for dropping them from the DT binding include. To avoid conflicts with
the old defines, rename them to use the CLK_COUNT suffix.

Signed-off-by: Artur Weber <aweber.kernel@gmail.com>

Changes in v4:
- Rename CLOCK_COUNT to CLK_COUNT to avoid redefinition

Changes in v3:
- Add this commit
