I looked at all HAVE_PWMs in the latest mainline kernel 3.14-rc1. Three platforms are still using HAVE_PWM as below: 1. ARM - PXA ./arch/arm/mach-pxa/Kconfig 2. ARM - NXP LPC32XX ./arch/arm/Kconfig config ARCH_LPC32XX select HAVE_PWM 3. MIPS - Ingenic JZ4740 based machines ./arch/mips/Kconfig config MACH_JZ4740 select HAVE_PWM However, the legacy PWM drivers for PXA, LPC32XX, and JZ474 were already moved to the generic PWM framework. ./drivers/pwm/pwm-pxa.c ./drivers/pwm/pwm-lpc32xx.c ./drivers/pwm/pwm-jz4740.c In conclusion, HAVE_PWM should be removed, because HAVE_PWM is NOT required anymore.

Through arm-soc tree [PATCH 1/7] ARM: pxa: don't select HAVE_PWM [PATCH 2/7] ARM: lpc32xx: don't select HAVE_PWM [PATCH 3/7] ARM: remove HAVE_PWM config option 2. Through MIPS tree [PATCH 4/7] MIPS: jz4740: don't select HAVE_PWM 3. Through Input tree [PATCH 5/7] Input: max8997_haptic: remove HAVE_PWM dependencies [PATCH 6/7] Input: pwm-beepe: remove HAVE_PWM dependencies 4. Through PWM tree [PATCH 7/7] pwm: don't use IS_ENABLED(CONFIG_HAVE_PWM) After merging these patches, all HAVE_PWM will be removed from the mainline kernel. Thank you. :-) Best regards, Jingoo Han
