Re: [PATCH 1/3] suniv: switch Allwinner F1Cx00 boards to OF_UPSTREAM

Dne nedelja, 19. januar 2025 ob 17:41:54 Srednjeevropski standardni čas je Andre Przywara napisal(a):

In contrast to some other Allwinner SoCs, there is no difference between the DTs for the Allwinner F1C100/F1C200 SoCs (sunvi) between the U-Boot and the Linux kernel repository.

Remove the old copies of the F1Cx00 related .dts and .dtsi files, and switch the whole suniv SoC over to use OF_UPSTREAM.
