First of all, I think you should break up this patch as per the 3 points that you mentioned above. The usage of opt_clks for this does not look right to me. Based on your description this clock is necessary and not optional on AM335x and on Davinci platforms this clock does not exist. I think the custom activate/deactivate functions in the OMAP runtime PM implementation was a good fit for keeping this SoC integration detail out of the driver code. However, the current DT flow in omap_device.c seems to assign the default activate/deactivate ops. Is that approach deprecated? Regards, Vaibhav

The issue is that this approach is not doable anymore with DT, that's why I had to provide a default set of functions. Regards, Benoit

I checked the DA830 TRM and looks like TBCLK for eHRPWM is an always on clock there. So, the only difference in AM335x is an additional enable bit. Instead of adding this as opt_clk in hwmod, we could add an always on clock node in Davinci clock data and have the driver always do a clk_enable() on the tbclk as part of the probe sequence. On AM335x, with the right clock node this will enable the clock in hardware and on DA830 it turns into a NOP. This way we can avoid adding the opt_clk entry in hwmod of eHRPWM. > > > > I think the custom activate/deactivate functions in the OMAP runtime PM > > implementation was a good fit for keeping this SoC integration detail out > > of the driver code.

Or will it get used in a different manner? Regards, Vaibhav

I will split the patches into 2. 1. One for correcting hwmod entries plus adding EQEP HWMOD entry 2.

I will remove opt_clk in HWMOD and made tbclk is a mandatory clock in EHRPWM driver. Thanks Avinash

As part of PWM subsystem integration, PWM subsystem are sharing resources like clock across submodules (ECAP, EQEP & EHRPWM). To handle resource sharing & IP integration 1. Rework on parent child relation between PWMSS and ECAP, EQEP & EHRPWM child devices to support runtime PM. 2. Add support for opt_clks in EHRPWM HWMOD entry to handle additional clock gating from control module. 3. Add HWMOD entries for EQEP PWM submodule.
