Subsequent patches then make use of the new API by providing a userspace offering via /sysfs. The final part of the set supplies PWM Capture functionality into the already existing STi PWM driver. This patch-set has been tested end to end via /sysfs. v2 => v3: - Supply DT documentation changes - Submit DTS additions as part of this set - Default Capture and PWM-out number of channels to 0 - Do additional checking, to ensure at least one channel is requested - Use global locking, instead of lock in device data v1 => v2: - API change - Use a struct to carry the result back to the caller - Use 'struct pwm' to store device specific data - Make timeout configurable - Don't use clear_bit(), instead use raw bit logic - Propagate return value of platform_get_irq() - Don't cast to (void *) - Move to subsystem terminology (channels => devices) - Remove channel select feature - Enable Capture IP during capture Lee Jones (20): ARM: dts: STi: Rename properites in line with PWM naming conventions ARM: dts: STiH407: Supply PWM Capture IRQ ARM: dts: STiH407: Declare PWM Capture data lines via Pinctrl ARM: dts: STiH416: Supply PWM Capture IRQs ARM: dts: STiH416: Declare PWM Capture data lines via Pinctrl ARM: dts: STiH416: Define PWM Capture clock ARM: dts: STiH416: Define the number of PWM Capture channels pwm: Add PWM Capture support pwm: sti: Rename channel => device pwm: sysfs: Add PWM Capture support pwm: sti: Reorganise register names in preparation for new functionality pwm: sti: Only request clock rate when you need to pwm: sti: Supply PWM Capture register addresses and bit locations pwm: sti: Supply PWM Capture clock handling pwm: sti: Initialise PWM Capture device data pwm: sti: Add support for PWM Capture IRQs pwm: sti: Add PWM Capture call-back pwm: sti: It's now valid for number of PWM channels to be zero pwm: sti: Take the opportunity to conduct a little house keeping dt-bindings: pwm: sti: Update DT bindings with recent changes Documentation/devicetree/bindings/pwm/pwm-st.txt | 10 +- arch/arm/boot/dts/stih407-family.dtsi | 5 +- arch/arm/boot/dts/stih407-pinctrl.dtsi | 3 + arch/arm/boot/dts/stih416-pinctrl.dtsi | 5 + arch/arm/boot/dts/stih416.dtsi | 12 +- drivers/pwm/core.c | 27 ++ drivers/pwm/pwm-sti.c | 424 +++++++++++++++++++---- drivers/pwm/sysfs.c | 17 + include/linux/pwm.h | 25 ++ 9 files changed, 447 insertions(+), 81 deletions(-) -- 2.8.3
