ARM: pxa: don't select HAVE_PWM

Commit Message

Jingoo Han Feb. 6, 2014, 9 a.m. UTC

The HAVE_PWM symbol is only for legacy platforms that provide
the PWM API without using the generic framework. PXA platforms
use the generic PWM framework, after the commit "17b2b47 pwm:
Move PXA PWM driver to PWM framework".

In the case of "CONFIG_HAVE_PWM=y && CONFIG_PWM=n", PXA platforms
make the build errors as below. Thus, selecting HAVE_PWM should
be removed from PXA platforms.

drivers/built-in.o: In function `lm3630a_pwm_ctrl':
drivers/video/backlight/lm3630a_bl.c:168: undefined reference to `pwm_config'
drivers/video/backlight/lm3630a_bl.c:172: undefined reference to `pwm_disable'
drivers/video/backlight/lm3630a_bl.c:170: undefined reference to `pwm_enable'
drivers/built-in.o: In function `lp855x_pwm_ctrl':
drivers/video/backlight/lp855x_bl.c:249: undefined reference to `pwm_config'
drivers/video/backlight/lp855x_bl.c:253: undefined reference to `pwm_disable'
drivers/video/backlight/lp855x_bl.c:251: undefined reference to `pwm_enable'
