[PATCH v2 0/2] Add PWM support for Intel Keem Bay SoC

[vineetha.g.jaya.kumaran@intel.com]

Hi,

This patch set enables support for PWM on the Intel Keem Bay SoC.
Keem Bay is an ARM based SoC, and the GPIO module allows
configuration of 6 PWM outputs. Patch 1 adds the PWM driver and
Patch 2 is for the required Device Tree bindings documentation.

This driver was tested on the Keem Bay evaluation module board.

Thank you.

Best regards,
Vineetha

Changes since v1:
-Updated licensing info, "clocks" property and example in DT bindings
-Updated name of DT bindings document to match compatible string
-Removed 1 patch for addition of new sysfs attribute "count"
-Added support for COMPILE_TEST in Kconfig
-Updated naming of defines and regmap attribute
-Updated calculation of waveform high time and low time
-Added range checking for waveform high/low time
-Implemented .get_state
-Removed register writes for lead-in and count values (left to default)
-Updated register access to single-access
-Folded keembay_pwm_enable/disable_channel, keembay_pwm_config_period/duty_cycle,
 and keembay_pwm_config into keembay_pwm_apply
-Updated error messages/error codes
-Removed pwm_disable from keembay_pwm_remove
-Removed clk_prepare/clk_enable/clk_disable from driver
