Subject: [PATCH V4 0/3] pwm: pxa: bug fix and device tree support

The patches fix some bugs
1. pwm-pxa driver is shared by ARCH_PXA and ARCH_MMP
2. use module_platform_driver for driver register

The patches also add device tree support for pwm.

V2->V1:
  Remove the redundant initialization.
  Fix bug of no initialization of .of_match_table.
  Use CONFIG_OF for device tree support. 
  Rebase to for-next

V3->V2:
  Change "mrvl,xxx" to "marvell,xxx".

V4->V3
  Change comments for "pwm: pxa: use module_platform_driver()"
  and "pwm: pxa: ARCH_MMP share same pwm driver with ARCH_PXA".
  Use "static const" for pxa_pwm_of_match definition.
  Use the below scheme for DT support.
  	if (!id_entry) {
		if (IS_ENABLED(CONFIG_OF))
			err = parse_dt();
		else
			err = -ENODEV;
	  } else {
  		err = parse_pdata();
	  }

	  if (err < 0)
		  return err;

Chao Xie (3):
  pwm: pxa: ARCH_MMP share same pwm driver with ARCH_PXA
  pwm: pxa: use module_platform_driver()
  pwm: pxa: add device tree support
