fa181d1a95 clk: ccf: replace the get_rate helper
The 12d152620d commit fixed the get_rate helper because the set_parent
one did not re-parent the clock device to the new parent. The 4d139f3838
commit allows you to remove this workaround by calling the
clk_get_parent_rate routine.

the clock driver should always force the Agilex's Clock Manager to

In SSBL, clock driver will skip the Clock Manager configuration

This patch adds this parameter in live tree API
- of_count_phandle_with_args
- ofnode_count_phandle_with_args
- dev_count_phandle_with_args

This parameter solves issue when these API is used to count

6038884483 clk: add clock driver for SCMI agents
This change introduces a clock driver for SCMI agent devices. When
SCMI agent and SCMI clock drivers are enabled, SCMI agent binds a
clock device for each SCMI clock protocol devices enabled in the FDT.

SCMI clock driver is embedded upon CONFIG_CLK_SCMI=y. If enabled,
CONFIG_SCMI_AGENT is also enabled.

SCMI Clock protocol is defined in the SCMI specification [1].

b364134f87 clk: get clock pointer before proceeding
clk_get_by_indexed_prop() retrieves a clock with dev member being set
with the pointer to the udevice for the clock controller driver. But
in case of CCF each clock driver has set in dev member the reference
to its parent (the root of the clock tree is a fixed clock, every
node in clock tree is a clock registered with clk_register()). In this
case the subsequent operations like dev_get_clk_ptr() on clocks
retrieved by clk_get_by_indexed_prop() will fail. For this, get the
pointer to the proper clock registered (with clk_register()) using
clk_get_by_id() before proceeding.

The previous version of the get_rate helper does not work if the mux
clock parent is changed after the probe. This error has not been
detected because this condition has not been tested. The error occurs
because the set_parent helper does not change the parent of the clock
device but only the clock selection register. Since changing the parent
of a probed device can be tricky, the new version of the get_rate helper
provides the rate of the selected clock and not that of the parent.
