Dear Maxime, with commit 49c726d55c1b ("clk: sunxi: Add Kconfig options"), you introduce various build configurations for Legacy clock support for Allwinner SoCs. Among them, you introduce the config CLK_SUNXI_PRCM_SUN9I in drivers/clk/sunxi/Kconfig, but this config is not used anywhere in the kernel tree. Can we just delete this config CLK_SUNXI_PRCM_SUN9I again, as it is not needed, or did you simply miss to adjust the Makefile for this option to be effective? I will gladly send a patch, once you could give me a quick pointer. Best regards, Lukas
