++	 * 2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz
++	 *
++	 * the second condition is based on new dchubp configuration. dppclk
++	 * for new dchubp may be different from dppclk before step 1.
++	 * for example, before step 1, dchubps are as below:

++	 * pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080)

++	 * new dchubp pipe split configuration:
++	 * pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080)
++	 * pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080)
++	 * dppclk only needs dppclk = dispclk /2.

++	 *
++	 * for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we
