* The SOR hardware blocks are driven by two clocks: a module clock that is

* pixel clock is called sorX_out. The source for the SOR pixel clock is
* referred to as the "parent" clock.
*
* On Tegra186 and newer, clocks are provided by the BPMP. Unfortunately the
* BPMP implementation for the SOR clocks doesn't exactly match the above in
* some aspects. For example, the SOR module is really clocked by the pad or
* sor_safe clocks, but BPMP models the sorX clock as being sourced by the
* pixel clocks. Conversely the sorX_out clock is sourced by the sor_safe or
* pad clocks on BPMP.
*
* In order to allow the display driver to deal with all SoC generations in
