clk: actions: Terminate clk_div_table with sentinel element

2022-04-15T12:14:52Z

[ Upstream commit d8a441e53e2434b1401e52dfd66b05263e442edc ] In order that the end of a clk_div_table can be detected, it must be terminated with a sentinel element (.div = 0). In owl-s900.s, the { 0, 8 } element was probably meant to be just that, so this patch changes { 0, 8 } to { 0, 0 }.

clk: actions: Fix factor clk struct member access

2020-01-27T13:51:14Z

[ Upstream commit ed309bfb4812e8b31a3eb877e157b8028a49e50c ] Since the helper "owl_factor_helper_round_rate" is shared between factor and composite clocks, using the factor clk specific helper function like "hw_to_owl_factor" to access its members will create issues when called from composite clk specific code. Hence, pass the "factor_hw" struct pointer directly instead of fetching it using factor clk specific helpers. This issue has been observed when a composite clock like "sd0_clk" tried to call "owl_factor_helper_round_rate" resulting in pointer dereferencing error. While we are at it, let's rename the "clk_val_best" function to "owl_clk_val_best" since this is an owl SoCs specific helper.

clk: actions: Don't reference clk_init_data after registration

2019-10-07T16:56:43Z

[ Upstream commit cf9ec1fc6d7cceb73e7f1efd079d2eae173fdf57 ] 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.
