clk: clocking-wizard: move dynamic reconfig setup behind flag

2024-10-09T23:38:56+00:00

Xilinx clocking wizard IP core's dynamic reconfiguration support is
optionally enabled at build time. Use the new boolean devicetree
property to indicate whether the hardware supports this feature or not.

clk: clocking-wizard: move clock registration to separate function

2024-10-09T23:38:56+00:00

Provide clear separation of dynamic reconfiguration logic, by moving its
setup procedure to its own dedicated function.

clk: clocking-wizard: use devres versions of clk_hw API

2024-10-09T23:38:55+00:00

Use device managed versions of the clk_hw API, entirely removing the
need for the driver's remove() callback and greatly simplifying the
probe() function's error paths.

clk: clocking-wizard: use newer clk_hw API

2024-10-09T23:38:24+00:00

Utilise clock provider API with struct clk_hw instances instead of the
consumer-side struct clk.

clk: clocking-wizard: simplify probe/remove with devres helpers

2024-10-09T23:38:24+00:00

Remove need to do various operations in remove callback and error paths
by utilising device managed versions of clock and notifier APIs.

clk: Switch back to struct platform_driver::remove()

2024-09-21T21:12:05+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all clk drivers to use .remove(), with the eventual goal to drop
struct platform_driver::remove_new(). As .remove() and .remove_new() have
the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

clk: clocking-wizard: Remove redundant initialization of pointer div_addr

2024-02-28T22:51:51+00:00

The pointer div_addr is being assigned a value that is never used, it is
being re-assigned a different value near the end of the function where
it is being read in the next statement. The initialization is redundant
and can be removed.

Cleans up clang scan build warning:
drivers/clk/xilinx/clk-xlnx-clock-wizard.c:501:16: warning: Value stored
to 'div_addr' during its initialization is never read [deadcode.DeadStores]

clocking-wizard: Add support for versal clocking wizard

2023-12-17T22:55:14+00:00

Add support for Clocking Wizard for Versal adaptive compute
acceleration platforms. The Versal clocking wizard differs
in the programming model and the register layout.
The CLKFBOUT_1 registers are at offset of 0x200
instead of the 0x330 in Versal. In Versal clocking wizard the low and
high time is programmed instead of the divisor.

clk: Explicitly include correct DT includes

2023-07-19T20:13:16+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.
