Downstream seems not to use _codec_clk, it just always uses the bit_div_clk as the codec's bit_clk.

Which would then allow us to drop the creation of "pxo" in gcc. I'm in favor of this plan, but this makes the change not only a transition from parent_names to parent_data, so could you please document that you're changing this parent. > > > + }, > > > .num_parents = 1, > > > .ops = &clk_pll_ops, > > > }, > > > @@ -64,9 +66,9 @@ static const struct parent_map lcc_pxo_pll4_map[] = { > > > { P_PLL4, 2 } > > > }; > > > > > > -static const char * const lcc_pxo_pll4[] = { > > > - "pxo", > > > - "pll4_vote", > > > +static const struct clk_parent_data lcc_pxo_pll4[] = { > > > + { .fw_name = "pxo", .name = "pxo" }, > > > + { .fw_name = "pll4_vote", .name = "pll4_vote" }, > > > > This is a reference to a clock defined in this same driver, so you can > > use { .hw = &pll4_vote.clkr.hw } to avoid the lookup all together. > > > > Eh... pll4_vote is defined in gcc (for some reason) the one we have here > is pll4. > > I asked if this could be fixed in some way but it was said that it's > better to not complicate things too much. > Sorry for the noise, I didn't pay attention to the gcc/lcc split. This seems reasonable. Presumably though, you should make the pxo -> pxo_board transition for .name here as well then?
