PX30 SoCs feature an ARM Bifrost GPU. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> --- Hello, this change is just adding basic GPU support, more work is needed on the devfreq/opp side to be sure everything works and is properly described. Hence, this proposal aims at describing the HW block only, not its hability to change voltages/frequencies.
