Otherwise, we do not add @num into the node name. Also, I do not see the point of having label backlight0 here. > + compatible = "pwm-backlight"; > + pwms = <&pwm2 0 500000>; > + power-supply = <®_3v3>; > + brightness-levels = < > + 100 99 98 97 96 95 94 93 92 91 > + 90 89 88 87 86 85 84 83 82 81 > + 80 79 78 77 76 75 74 73 72 71 > + 70 69 68 67 66 65 64 63 62 61 > + 60 59 58 57 56 55 54 53 52 51 > + 50 49 48 47 46 45 44 43 42 41 > + 40 39 38 37 36 35 34 33 32 31 > + 30 29 28 27 26 25 24 23 22 21 > + 20 19 18 17 16 15 14 13 12 11 > + 10 9 8 7 6 5 4 3 2 1 > + 0 Why is it so unique to start with 100 and end with 0? Does it even work? Here is what I read from bindings doc. - brightness-levels: Array of distinct brightness levels. Typically these are in the range from 0 to 255, but any range starting at 0 will do. The actual brightness level (PWM duty cycle) will be interpolated from these values. 0 means a 0% duty cycle (darkest/off), while the last value in the array represents a 100% duty cycle (brightest). > + >; > + default-brightness-level = <50>; > + }; > + > + regulators { > + compatible = "simple-bus"; This property can be dropped, since it's already defined in imx53-tx53.dtsi? > + > + reg_lcd_pwr: regulator@5 { The DT convention is that you need to have a property 'reg = <num>' if the node name is xxx@num. > + compatible = "regulator-fixed"; > + regulator-name = "LVDS0 POWER"; > + regulator-min-microvolt = <3300000>; > + regulator-max-microvolt = <3300000>; > + gpio = <&gpio2 31 GPIO_ACTIVE_HIGH>; > + enable-active-high; > + regulator-boot-on; > + }; > + > + reg_lcd_reset: regulator@6 { > + compatible = "regulator-fixed"; > + regulator-name = "LVDS1 POWER"; > + regulator-min-microvolt = <3300000>; > + regulator-max-microvolt = <3300000>; > + gpio = <&gpio3 29 GPIO_ACTIVE_HIGH>; > + enable-active-high; > + regulator-boot-on; > + }; > + }; > +}; > + > +&i2c3 { > + status = "okay"; > + We generally put 'status' at the bottom of the property list.

I tried to add polarity support in the generic PWM layer, so that all HW drivers that do not support inversion in HW can make use of it, but this gives problems with client drivers that don't know about the inversion and disable the PWM when the duty cycle is set to 0. Maybe I'll find some time to find a proper solution for this issue. Lothar Waßmann

Actually the i.MX supports inversion in hardware. It's bit 18 in the PWMCR register. As a sidenote IMO client drivers shouldn't make assumptions about the pwm output when a pwm is disabled anyway. If clients want to have a constant output they should set the duty cycle to 0 or 100%. Sascha

This patch adds support for the Ka-Ro electronics GmbH TX53 modules. There are two distinct module types. One with an LVDS display interface and SATA support, the other with a parallel LCD interface and no SATA interface.
