From 4457ee2f99f7286d037ccde8c107481b6105fc15 Mon Sep 17 00:00:00 2001 From: Karl Mehltretter Date: Sun, 12 Jul 2026 18:03:01 +0200 Subject: [PATCH] clk: aspeed: ast2700: select AUXILIARY_BUS The AST2700 clock driver also exposes the SoC reset controller: it hands its register base to a reset auxiliary device via devm_auxiliary_device_create(), which the separate ASPEED reset driver (RESET_ASPEED) then binds to. That create call needs the auxiliary bus core (AUXILIARY_BUS), not the reset driver itself, but COMMON_CLK_AST2700 does not select AUXILIARY_BUS. It builds today only because RESET_ASPEED selects AUXILIARY_BUS and is normally enabled alongside the clock driver. On a randconfig with COMMON_CLK_AST2700=y and RESET_ASPEED=n, nothing pulls the auxiliary bus in and the kernel fails to link: ld: drivers/clk/aspeed/clk-ast2700.o: in function `ast2700_soc_clk_probe': clk-ast2700.c:(.text+0x147c): undefined reference to `__devm_auxiliary_device_create' Select AUXILIARY_BUS directly, as other clock drivers that create auxiliary devices do, so it builds regardless of the reset driver.
