Here is a patch that fixes it. Feel free to replace it with a different patch if you don't like this version. 8<-------- Subject: clk: omap: compile legacy omap3 clocks conditionally The 'ARM: OMAP3: legacy clock data move under clk driver' patch series causes build errors when CONFIG_OMAP3 is not set: drivers/clk/ti/dpll.c: In function 'ti_clk_register_dpll': drivers/clk/ti/dpll.c:199:31: error: 'omap3_dpll_ck_ops' undeclared (first use in this function) const struct clk_ops *ops = &omap3_dpll_ck_ops; ^ drivers/clk/ti/dpll.c:199:31: note: each undeclared identifier is reported only once for each function it appears in drivers/clk/ti/dpll.c:259:10: error: 'omap3_dpll_per_ck_ops' undeclared (first use in this function) ops = &omap3_dpll_per_ck_ops; ^ drivers/built-in.o: In function `ti_clk_register_gate': drivers/clk/ti/gate.c:179: undefined reference to `clkhwops_omap3430es2_dss_usbhost_wait' drivers/clk/ti/gate.c:179: undefined reference to `clkhwops_am35xx_ipss_module_wait' -in.o: In function `ti_clk_register_interface': drivers/clk/ti/interface.c:100: undefined reference to `clkhwops_omap3430es2_iclk_hsotgusb_wait' drivers/clk/ti/interface.c:100: undefined reference to `clkhwops_omap3430es2_iclk_dss_usbhost_wait' drivers/clk/ti/interface.c:100: undefined reference to `clkhwops_omap3430es2_iclk_ssi_wait' drivers/clk/ti/interface.c:100: undefined reference to `clkhwops_am35xx_ipss_wait' drivers/built-in.o: In function `ti_clk_register_composite': :(.text+0x3da768): undefined reference to `ti_clk_build_component_gate' In order to fix that problem, this patch makes the omap3 legacy code compiled only when both CONFIG_OMAP3 and CONFIG_ATAGS are set.
