clk: fixed_rate: Avoid calling dev_read_*() if CONFIG_OF_PLATDATA=y

2025-12-27T15:01:05+00:00

If CONFIG_OF_PLATDATA=y , then the udevice has no valid OF node associated
with it and ofnode_valid(node) evaluates to 0. The dev_read_u32_default()
call ultimately reaches ofnode_read_u32_index() which invokes fdt_getprop()
and passes result of ofnode_to_offset(node) as an offset parameter into it.

The ofnode_to_offset(node) returns -1 for invalid node, which leads to an
fdt_getprop(..., -1, ...) invocation, which will crash sandbox with SIGSEGV
because libfdt can not handle negative node offsets without full tree check,
which U-Boot inhibits to keep size lower.

Add dev_has_ofnode(dev) check and do not assign clock rate in case the
device has no valid node associated with it, and do not call any of the
dev_read_*() functions for devices without valid nodes.

clk: fixed_rate: configure clock ID with CONFIG_CLK_AUTO_ID

2025-06-11T07:42:55+00:00

Update CLK ID to avoid 0 id, used for dummy clock with CCF
and to allow selection by clk_get_by_id, used to
get private data associated to the UCLASS_CLK device

Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"

2024-05-20T19:35:03+00:00

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

clk: define LOG_CATEGORY for generic and ccf clocks

2021-12-15T17:16:16+00:00

Define LOG_CATEGORY to allow filtering with log command
for generic clock and CCF clocks.

This patch also change existing printf, debug and pr_ macro
to log_ or dev_ macro.

clk: fixed_rate: add dummy disable() function

2021-10-19T15:25:25+00:00

commit 6bf6d81c1112 ("clk: fixed_rate: add dummy enable() function")
implemented .enable, so fixed rate clocks can be used where drivers
might call clk_enable(). Implement the .disable op for the same reason;
some drivers, e.g. USB PHYs, may attempt to disable clocks at runtime.

treewide: Try to avoid the preprocessor with OF_REAL

2021-09-25T15:46:15+00:00

Convert some of these occurences to C code, where it is easy to do. This
should help encourage this approach to be used in new code.

treewide: Use OF_REAL instead of !OF_PLATDATA

2021-09-25T15:46:15+00:00

Now that we have a 'positive' Kconfig option, use this instead of the
negative one, which is harder to understand.

clk: fixed_rate: add API for directly registering fixed rate clocks

2021-06-11T11:04:52+00:00

Current driver only supports registering fixed rate clocks from DT. Add
new API which makes it possible to register fixed rate clocks directly
from e.g. platform specific clock drivers.
