/**
 * @file PWM driver for Freescale K64 FlexTimer Module (FTM)
 *
 * This file implements Pulse Width Modulation using the Freescale FlexTimer
 * Module (FTM).  Basic functionality is implemented using edge-aligned PWM
 * mode.  More complex functionality such as non-zero phase is not supported
 * since combined mode operation is not implemented.
 *
 * The following configuration options are supported. ("x" can be one of the
 * following values: 0, 1, 2, or 3 representing one of the four FMT modules
 * FTM0, FTM1, FTM2, or FTM3.)
 *
 * - CONFIG_PWM_K64_FTM_x_DEV_NAME: string representing the device name
 * - CONFIG_PWM_K64_FTM_x_PRESCALE: the clock prescaler value
 * - CONFIG_PWM_K64_FTM_x_CLOCK_SOURCE: the clock source
 * - CONFIG_SYS_LOG_PWM_K64_FTM_LEVEL: sets log output level for the driver
 * - CONFIG_STDOUT_CONSOLE: choose debug logs using printf of printk
 *
 * The following configuration options need to be defined in
 * soc.h or board.h ("x" can be 0, 1, 2 or 3).
 * - PWM_K64_FTM_x_REG_BASE: the base address of FTM (FTMx_SC)
 *
 * The following configuration options are not supported.  These are place
 * holders for future functionality
 *
 * - CONFIG_PWM_K64_FTM_x_PHASE_ENABLE_0 support non-zero phase on channel 0
 * - CONFIG_PWM_K64_FTM_x_PHASE_ENABLE_1 support non-zero phase on channel 1
 * - CONFIG_PWM_K64_FTM_x_PHASE_ENABLE_2 support non-zero phase on channel 2
 * - CONFIG_PWM_K64_FTM_x_PHASE_ENABLE_3 support non-zero phase on channel 3
