The rk3399 hdmi phy is supplied by the vpll directly and needs to adapt that frequency depending on the selected resolution on the hdmi output. For the hdmi-phy the vpll frequency is supplied unchanged without any dividers being present there. The vpll also is one of the sources the general display clock of the visual output processor (vop) and as it is somewhat special for display operations possibly also the preferred pll source. Here a divider is available between the pll-mux and the vop clock, so that this part can adapt the resulting frequency if needed. So to keep the vop clock in line with the target rate, set the newly introduced CLK_KEEP_REQ_RATE flag for the dclk_vop clocks on rk3399. Signed-off-by: Heiko Stuebner <heiko@...>
