    Subject[PATCH 0/7] Remove HAVE_PWM config option
    Date
    The HAVE_PWM symbol is only for legacy platforms that provide
    the PWM API without using the generic framework, while PWM symbol
    is used for PWM drivers using the generic PWM framework.

    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.

    Jingoo Han (7):
    ARM: pxa: don't select HAVE_PWM
    ARM: lpc32xx: don't select HAVE_PWM
    ARM: remove HAVE_PWM config option
    MIPS: jz4740: don't select HAVE_PWM
    Input: max8997_haptic: remove HAVE_PWM dependencies
    Input: pwm-beepe: remove HAVE_PWM dependencies
    pwm: don't use IS_ENABLED(CONFIG_HAVE_PWM)

    arch/arm/Kconfig | 4 ----
    arch/arm/mach-pxa/Kconfig | 15 ---------------
    arch/mips/Kconfig | 1 -
    drivers/input/misc/Kconfig | 4 ++--
    include/linux/pwm.h | 2 +-
    5 files changed, 3 insertions(+), 23 deletions(-)

    I would like to merge these patches as below:

    1. 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
