ARM: dts: Set GPU to use DPLL_GPU as clock source In the current clock configuration, GPU derives its clocks from DPLL_CORE H14 output called CORE_GPU_CLK. The multipliers, dividers and post-dividers are set in the u-boot according to the desired clock rate. However, if it is required to set GPU to different OPPs based on u-boot config, kernel clock framework requires a. either changing the H14 post-divider, which is an impossible integer for GPU OPP clock recommendation (425.6 MHz), or b. affect the clock setting for other clocks of DPLL_CORE. It is, therefore, desirable to set GPU to use DPLL_GPU to derive its clocks by using the DT standard properties "assigned-clocks" and "assigned-clock-parents". This patch also sets the initial values for the DPLL_GPU outputs. These values are chosen based on the OPP_NOM values defined as per recommendation from design team. The DPLL locked frequency is kept at 1277 MHz, so that the value for the divider clock, dpll_gpu_m2_ck, can be set to 425.67 MHz for OPP_NOM. Signed-off-by: Subhajit Paul <subhajit_paul@ti.com>
