Subject: [RESEND PATCH v6 5/5] ARM: dts: rockchip: set PWM delay backlight settings for Minnie
Date: Wed, 28 Mar 2018 19:03:27 +0200 [thread overview]
Message-ID: <20180328170327.5395-5-enric.balletbo@collabora.com> (raw)
In-Reply-To: <20180328170327.5395-1-enric.balletbo@collabora.com>
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.

Changes since v5:
- None.
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
