2930 * The SOR hardware blocks are driven by two clocks: a module clock that is

2932 * pixel clock that also drives the head attached to the SOR. The module
2933 * clock is typically called sorX (with X being the SOR instance) and the
2934 * pixel clock is called sorX_out. The source for the SOR pixel clock is
2935 * referred to as the "parent" clock.
2937 * On Tegra186 and newer, clocks are provided by the BPMP. Unfortunately the
2938 * BPMP implementation for the SOR clocks doesn't exactly match the above in
2939 * some aspects. For example, the SOR module is really clocked by the pad or
2940 * sor_safe clocks, but BPMP models the sorX clock as being sourced by the
2941 * pixel clocks. Conversely the sorX_out clock is sourced by the sor_safe or
2942 * pad clocks on BPMP.
