global: Correct duplicate U_BOOT_DRIVER entry names

2026-04-07T17:32:56+00:00

The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

clk: Tighten some clock driver dependencies

2025-10-28T18:25:23+00:00

A few clock drivers cannot build without access to some platform
specific header files. Express those requirements in Kconfig as well.

clk: at91: Fix use of unsigned loop index

2025-08-13T09:59:36+00:00

The use of the unsigned variable 'i' as a loop index leads to the test
for i being non-negative always being true. Instead declare 'i' as an
int so that the for loop will terminate as expected.
If the original for loop completes 'i' will be 1 past the end of the
array so decrement it in the subsequent error path to prevent an out of
bounds access occurring.

clk: at91: Fix testing of unsigned variable to be negative

2025-08-13T09:59:36+00:00

The variable 'index' is declared as unsigned but used to receive the
return value of a function returning 'int'. This value is then tested
for being less than zero to detect an error condition but as index is
unsigned this can never be true. Change the variable 'index' to be an
int so that the error condition can be detected.

clk: at91: clk-main: drop parent_name check when registering main_rc oscillator

2025-06-19T10:56:43+00:00

The clk_register function logs an error if parent_name is missing from the
Device Tree.On the SAM9X7, the main_rc node is omitted to stay aligned with
the Linux Device Tree.Remove the parent_name check in at91_clk_main_rc()
to allow it to pass NULL when the parent is not specified.
