I guess it may depend on your boards, but DT might contain safe default configuration that would work on all variants, so if you have for example 1 GiB and 2 GiB variants, 1 GiB configuration here should be fine to get the board running even without a bootloader that could inject remaining data.

I wonder if we already have this kind of #define defined. Keep in mind that this value is specific for Exynos SoCs, so we would need to define it in Exynos-specific header, like include/dt-bindings/pinctrl/exynos.h.
+&pinctrl_3 { + backlight_pwm: backlight-pwm { + samsung,pins = "gpb2-0"; + samsung,pin-function = <2>; + samsung,pin-pud = <0>; + samsung,pin-drv = <0>; + };The PWM probably belongs in exynos5420-pinctrl.dtsi (though you'd need to call it by a more generic name since it could be used for something other than a backlight).
Yes, please add generic pinctrl nodes for all PWM outputs on the SoC to exynos5420-pinctrl.dtsi, as done in exynos4x12-pinctrl.dtsi (see pwmX-out nodes).
