Neil Armstrong 02d249f99e rng: meson: make core clock optional ... This fixes HWRNG support on Amlogic GXL, GXM, G12A, G12B & SM1 based boards dues to the lack of the core clock in the device tree. It was reported breaking EFI boot in the Linux EFI stub, because the EFI_RNG_PROTOCOL didn't check for the RNG device presence before installing itself. The Linux amlogic,meson-rng.yaml doesn't mandate the core clock, this the clock should be ignores if not present. Nevertheless, the clock should be present and this should be fixed on the Linux meson-gxl.dtsi & meson-g12-common.dtsi then synced with U-Boot. The change has been tested on a Khadas VIM3, which uses the common meson-g12-common.dtsi like the Odroid-C4 & Odroid-N2 in Scott's report, along with the RNG cmd.
