The changeset fixes a number of issues within current implementation of LPC32xx PWM controller driver, namely - the SoC has two independent PWM controllers with one channel each, - runtime warnings from common clock framework, - overflow in duty cycle calculation may result in disabled PWM, - unsupported period values are not accepted. Correction of PWM channels requires a correspondent change in arch/arm/boot/dts/lpc32xx.dtsi, it has been already sent for review. Changes from v1 to v2: - corrected style of examples in documentation, - improved commit messages Version v1 can be found here: http://comments.gmane.org/gmane.linux.pwm/2828 http://www.spinics.net/lists/devicetree/msg105398.html Vladimir Zapolskiy (6): dt: lpc32xx: pwm: correct LPC32xx PWM device node example dt: lpc32xx: pwm: update documentation of LPC32xx PWM device pwm: lpc32xx: correct number of PWM channels from 2 to 1 pwm: lpc32xx: fix warnings from common clock framework pwm: lpc32xx: fix and simplify duty cycle and period calculations pwm: lpc32xx: return ERANGE, if requested period is not supported .../devicetree/bindings/pwm/lpc32xx-pwm.txt | 9 +++- drivers/pwm/pwm-lpc32xx.c | 59 ++++++++-------------- 2 files changed, 29 insertions(+), 39 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
