pwm: davinci: Add Kconfig support for ECAP & EHRPWM devices
Add EHRPWM and ECAP support build support for DAVINCI_DA8XX platforms. Also, since DAVINCI platforms doesn't support TI-PWM-Subsystem module, remove the select option for CONFIG_PWM_TIPWMSS. Also, update CONFIG_PWM_TIPWMSS compiler directive appropriately in pwm-tipwmss.h to fix the below compiler error upon removal of CONFIG_PWM_TIPWMSS for DAVINCI platforms. drivers/pwm/pwm-tiecap.c: In function 'ecap_pwm_probe': drivers/pwm/pwm-tiecap.c:263:4: error: 'PWMSS_ECAPCLK_EN' undeclared (first use in this function) drivers/pwm/pwm-tiecap.c:263:4: note: each undeclared identifier is reported only once for each function it appears in drivers/pwm/pwm-tiecap.c:264:17: error: 'PWMSS_ECAPCLK_EN_ACK' undeclared (first use in this function) drivers/pwm/pwm-tiecap.c: In function 'ecap_pwm_remove': drivers/pwm/pwm-tiecap.c:291:49: error: 'PWMSS_ECAPCLK_STOP_REQ' undeclared (first use in this function) make[2]: *** [drivers/pwm/pwm-tiecap.o] Error 1 make[1]: *** [drivers/pwm] Error 2 make: *** [drivers] Error 2 Signed-off-by: Philip Avinash <avinashphilip@ti.com> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
