/*
 * The SOR hardware blocks are driven by two clocks: a module clock that is
 * used to access registers and a pixel clock that is sourced from the same
 * pixel clock that also drives the head attached to the SOR. The module
 * clock is typically called sorX (with X being the SOR instance) and the
 * 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
 * a unified way, implement the BPMP semantics in this driver.
