Yes it should be possible to support other PMIC other than TWL chips too.. What you're seeing is a bug. > arch/arm/mach-omap2/built-in.o: In function `omap_set_pwrdm_state': > /local/linux-3.0/arch/arm/mach-omap2/pm.c:122: undefined reference to > `pwrdm_read_next_pwrst' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:126: undefined reference to > `pwrdm_read_pwrst' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:127: undefined reference to > `pwrdm_read_pwrst' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:133: undefined reference to > `pwrdm_wait_transition' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:138: undefined reference to > `pwrdm_set_next_pwrst' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:153: undefined reference to > `pwrdm_set_lowpwrstchange' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:159: undefined reference to > `pwrdm_wait_transition' > /local/linux-3.0/arch/arm/mach-omap2/pm.c:160: undefined reference to > `pwrdm_state_switch' > arch/arm/mach-omap2/built-in.o: In function > `omap_hwmod_get_context_loss_count': > /local/linux-3.0/arch/arm/mach-omap2/omap_hwmod.c:2638: undefined reference > to `pwrdm_get_context_loss_count' > arch/arm/mach-omap2/built-in.o: In function `_clkdm_clk_hwmod_disable': > /local/linux-3.0/arch/arm/mach-omap2/clockdomain.c:895: undefined reference > to `pwrdm_clkdm_state_switch' > arch/arm/mach-omap2/built-in.o: In function `clkdm_allow_idle': > /local/linux-3.0/arch/arm/mach-omap2/clockdomain.c:786: undefined reference > to `pwrdm_clkdm_state_switch' > arch/arm/mach-omap2/built-in.o: In function `_clkdm_clk_hwmod_enable': > /local/linux-3.0/arch/arm/mach-omap2/clockdomain.c:869: undefined reference > to `pwrdm_wait_transition' > /local/linux-3.0/arch/arm/mach-omap2/clockdomain.c:870: undefined reference > to `pwrdm_clkdm_state_switch' > arch/arm/mach-omap2/built-in.o: In function `_clkdm_register': > /local/linux-3.0/arch/arm/mach-omap2/clockdomain.c:79: undefined reference to > `pwrdm_lookup' > /local/linux-3.0/arch/arm/mach-omap2/clockdomain.c:93: undefined reference to > `pwrdm_add_clkdm' > arch/arm/mach-omap2/built-in.o: In function `omap2_clk_disable_unused': > /local/linux-3.0/arch/arm/mach-omap2/clock.c:442: undefined reference to > `pwrdm_clkdm_state_switch' > arch/arm/mach-omap2/built-in.o: In function > `omap2_init_common_infrastructure': > /local/linux-3.0/arch/arm/mach-omap2/io.c:355: undefined reference to > `omap3xxx_voltagedomains_init' > /local/linux-3.0/arch/arm/mach-omap2/io.c:356: undefined reference to > `omap3xxx_powerdomains_init' > > > Any ideas? I'd like to keep my changes to the kernel to > a minimum, Sounds like there should be empty functions for the prdm_* functions in this case. Kevin might have some patches to fix this already.
