Subject: [RFCv2][PATCHv5 0/4] Add Freescale FTM PWM driver.
Date: Wednesday 30th October 2013 06:23:20 UTC (over 3 years ago)
Hello, This patch series is the Freescale FTM PWM implementation. And there are 8 channels most supported by the FTM PWM. This implementation is only compatible with device tree definition. This patch series is based on linux-next and has been tested on Vybrid VF610 Tower board using device tree. Changes in RFCv2 of PATVHv5: - Remove "fsl,pwm-counter-clk"(all the four patches are modified). Changes in v5: - Remove active/idle pinctrl stuff. Changes in v4: - Check for the result and return an error for devm_kzalloc(). - Move pinmux setting from the SoC file to the board specific file. - Revise the written mistake of 'ret |= FTMSC_CLKEXT;' --> 'reg |= FTMSC_CLKEXT;'. Changes in v3: - Remove "availabe" field. - Remove "fsl,pwm-avaliable-chs" property. - ... Changes in v2: - Remove PWM CPWM/EPWM feature and sysfs. - Remove some redundant code. - Revise some code for more readable. - Remove "fsl,pwm-clk-ps", "fsl,pwm-number", "fsl,pwm-channels",etc. - Add "fsl,pwm-avaliable-chs", "fsl,pwm-counter-clk", etc. - Support 8 channels default in dtsi file. - Add counter clock source selection. - Rename some function name, macro name, etc. - Use PWM's and OF's existing function interfaces. - Split clk_unprepare_enable to clk_unprepare and clk_enable,etc. - ... Added in v1: - Add Freescale FTM PWM driver support. - Add Freescale FTM PWM node for VF610. - Enable Enables FTM PWM device for Vybrid VF610 TOWER. - Add device tree bindings for Freescale.
