The voltage domain code wants the voltage tables, which are in the opp*.c files. These files aren't built when PM_OPP is disabled, causing the following build errors at link time: twl-common.c:(.init.text+0x2e48): undefined reference to `omap34xx_vddmpu_volt_data' twl-common.c:(.init.text+0x2e4c): undefined reference to `omap34xx_vddcore_volt_data' twl-common.c:(.init.text+0x2e5c): undefined reference to `omap36xx_vddmpu_volt_data' twl-common.c:(.init.text+0x2e60): undefined reference to `omap36xx_vddcore_volt_data' twl-common.c:(.init.text+0x2830): undefined reference to `omap44xx_vdd_mpu_volt_data' twl-common.c:(.init.text+0x283c): undefined reference to `omap44xx_vdd_iva_volt_data' twl-common.c:(.init.text+0x2844): undefined reference to `omap44xx_vdd_core_volt_data' Acked-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
