      ARM: pxa: hx4700: Fix backlight PWM device number · 8d6b00f5
      Paul Parsons 提交于
      Recent changes to PXA PWM support changed the PXA27X PWM device
      numbering scheme.
      
      The linux-3.5 PXA PWM driver followed the hardware numbering scheme for
      the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear
      numbering scheme:
      
      Address		Hardware	3.5 pwm_id	3.6-rc1 pwm_id
      0x40b00000	PWM0		0		0
      0x40b00010	PWM2		2		1
      0x40c00000	PWM1		1		2
      0x40c00010	PWM3		3		3
      
      The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id
      must be changed from 1 to 2.
      
      This patch fixes the backlight PWM device number and at the same time
      moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).
