Most of the changes are not yet in-tree. The phone has a PWM vibrator for which the corresponding input driver (pwm-vibrator) is used. The driver used for the PWM is pwm-pxa (or pxa25x-pwm). The DT nodes look like this [...] pwm: pwm@1ac00 { compatible =3D "marvell,pxa250-pwm"; reg =3D <0x1ac00 0x10>; #pwm-cells =3D <1>; clocks =3D <&apbc PXA1908_CLK_PWM3>; }; [...] vibrator { compatible =3D "pwm-vibrator"; pwm-names =3D "enable"; pwms =3D <&pwm 100000>; enable-gpios =3D <&gpio 20 GPIO_ACTIVE_HIGH>; pinctrl-names =3D "default"; pinctrl-0 =3D <&vibrator_pins>; }; [...] The vibrator worked fine with v6.8-rc6 but after I rebased to v6.9-rc1, it no longer probes printing [ +0.000118] pwm-vibrator vibrator: failed to apply initial PWM state: -2= 2 to dmesg. I have bisected the problem to 40ade0c2e794 ("pwm: Let the of_xlate callbacks accept references without period"). Looking at the commit and adjacent history, I don't believe this problem is caused by this still being an out-of-tree DT, nonetheless, if it proves to be the case, then I apologize for false alarm. Would you please take a look? Thank you and kind regards, K. B. #regzbot introduced: 40ade0c2e794
