2024-12-02module: Convert symbol namespace to string literalPeter Zijlstra
Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

2024-07-29clk: meson: introduce symbol namespace for amlogic clocksJerome Brunet
Symbols exported by the Amlogic clock modules are only meant to be used by Amlogic clock controller drivers. Using a dedicated symbols namespace make that clear and help clean the global namespace of symbols other modules do no need.

2024-04-10clk: meson: add vclk driverNeil Armstrong
The VCLK and VCLK_DIV clocks have supplementary bits. The VCLK gate has a "SOFT RESET" bit to toggle after the whole VCLK sub-tree rate has been set, this is implemented in the gate enable callback. The VCLK_DIV clocks as enable and reset bits used to disable and reset the divider, associated with CLK_SET_RATE_GATE it ensures the rate is set while the divider is disabled and in reset mode. The VCLK_DIV enable bit isn't implemented as a gate since it's part of the divider logic and vendor does this exact sequence to ensure the divider is correctly set.
