Subject: [PATCH v5 5/5] ARM: dts: rockchip: set PWM delay backlight settings for Minnie
The minnie devices comes with an AUO B101EAN01 panel which is different
from default veyron devices, thus the power on/off timing sequence is
slightly different. The datasheet specifies a pwm delay of 200 ms, so
update the PMW delay proprieties accordingly.

Heiko,
I'm not able to test this patch in a minnie device because I don't have
one, so could you do a quick try, please?
Changes since v4:
- Rebase on top of mainline.
Changes since v3:
- Use new -ms names for proprieties.
- Fix the delay, should be 200ms instead of 20ms (Pavel)
Changes since v2:
- Use new names for proprieties.
Changes since v1:
- Add this new patch as minnie has differents timings
