This series introduces the driver for the Kona PWM controller found in Broadcom mobile SoCs like bcm281xx and updates the device tree and the defconfig to enable use of this hardware on the bcm28155 AP board. Changes since v4: - Added in real polarity support - Labeled trigger bits as such rather than use the name from hw docs - Listed unsual hardware characteristics at the top of the file - Removed default from Kconfig and update defconfig accordingly - Always use unsigned int for temporary register values Changes since v3: - Removed polarity support for now - Cleaned up whitespace issues, shortened some variable names - Use container_of instead of dev_get_drvdata to get private data - Removed workaround for PWM framework bug - Reworded some binding documentation Changes since v2: - SoC DTS file updated to use real clock's phandle + specifier - Toggle smooth mode off during apply so new settings take immediately Changes since v1: - Fixed up macros to be clearer and more complete - Corrected spelling and punctuation mistakes - Added support for polarity - Made peripheral clock use more efficient - Made prescale and duty computation clearer - Moved Makefile addition to keep alphabetical - Split complex lines into multiple steps Dependencies: The "ARM: dts: Declare the PWM for bcm11351 (bcm281xx)" patch depends upon "ARM: dts: bcm281xx: define real clocks" which is queued up in for-next of arm-soc.
