Is there a pwm driver in KK4.4.3 U-boot for SabreSD?

There is a pwm driver in kk4.4.2 U-boot: /bootable/bootloader/uboot-imx/drivers/misc/imx_pwm.c


But this driver is removed from KK4.4.3, and I does not found how SabreSD controlled the pwm signal on DISP0_PWM(Pad name:SD1_DAT3) inU-boot

If I want to change the frequency on pad SD1_DAT3 and add a pwm signal from pad DISP0_DAT9 in U-boot on SabreSD, is there an easy way to control that?
