Commit b681af0bc1cc ("drm: panfrost: add optional bus_clock") added an optional bus_clock to support Allwinner H6 T-720 GPU. Increase the max clock items in the dt-binding to reflect this.
Bifrost GPU in Rockchip RK3568 SoCs also has a core and a bus clock and it gets added here in a (very) similar way it was done for allwinner,sun50i-h6-mali compatible in arm,mali-midgard binding.
