I'm sending a patch that sets the pxo_board fixed clock in dts to output "pxo". The only clock that still use pxo_board is rpm, everything else at least for ipq806x use pxo and i'm sending a patch to use pxo for rpm. Considering pxo is always present and pxo_board should be dropped because every ipq806x driver use "pxo". What is correct naming pxo or pxo_board?

I assume pxo right? This might be not the case for the ipq806x, but here is the story for all other (old) platforms: - gcc driver manually registered pxo/cxo/xo fixed factor clocks. - Then we started adding *xo_board clocks to the DT, as they represent the external oscillators - PXO clock consumers receive a clocks entry with clock-names = "pxo" which points to the pxo_board - All clock drivers are now being switched to use .fw_name = "pxo", .name = "pxo_board" to use the DT-defined pxo_board clock. Hopefully at some point we can then drop the manually registered pxo clock and always use the DT-based one. -- With best wishes Dmitry ^ permalink raw reply [flat|nested] 12+ messages in thread

I got confused since looking at the code factor clock is really just a hack to handle both driver that use pxo_board and pxo cause from what I notice it's the same clock with different naming. Sooo keep using pxo_board with the fact that pxo is always present seems to be redundant but if that's the pattern then I will just keep pxo_board in .name where it's used. > -- > With best wishes > Dmitry -- Ansuel ^ permalink raw reply [flat|nested] 12+ messages in thread
