2023-08-22clk: Annotate struct clk_hw_onecell_data with __counted_byKees Cook1-2/+1
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct clk_hw_onecell_data. Additionally, since the element count member must be set before accessing the annotated flexible array member, move its initialization earlier.

2023-03-30clock: milbeaut: use devm_platform_get_and_ioremap_resource()Minghao Chi1-3/+1
Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does.

2019-08-16clk: milbeaut: Don't reference clk_init_data after registrationStephen Boyd1-1/+1
A future patch is going to change semantics of clk_register() so that clk_hw::init is guaranteed to be NULL after a clk is registered. Avoid referencing this member here so that we don't run into NULL pointer exceptions.

2019-04-26clock: milbeaut: Add Milbeaut M10V clock controllerSugaya Taichi1-0/+663
The M10V of the Milbeaut SoCs has an on-chip controller that derive mostly clocks from a single external clock, using PLLs, dividers, multiplexers and gates. Since the PLLs have already been started and will not stop / restart, they are fixed factor. The gates will be added in later patch (all of the gates are off state now).
