2019-07-23ARM: dts: sunxi: Remove simple-panel compatibleMaxime Ripard1-1/+1
simple-panel based bindings need only the display compatible, and simple-panel isn't documented anywhere. Remove it. Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
2019-03-25ARM: dts: sun8i: a23/a33: Fix Display Engine DTC warningsMaxime Ripard1-0/+6
Our display engine endpoints trigger some DTC warnings due to the fact that we're having a single endpoint that doesn't need any reg property, and since we don't have a reg property, we don't need the address-cells and size-cells properties anymore. Fix those Acked-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
2019-01-25ARM: dts: sun8i-a23-q8: Set compatible string for LCD panelChen-Yu Tsai1-0/+4
The Q8 tablets follow the A23/A33 tablet reference design, and normally use a "generic" 800x480 LCD panel. The actual panel may vary between production runs, and there are no visible markings denoting its model. This patch uses a panel that has the same dimensions and timings that are close to what was provided in the vendor fex files. Since there are also A33 Q8 tablets with 1024x600 panels, this patch only sets the compatible string for A23 Q8 tablets.

2017-03-27ARM: dts: sun8i-a23-q8-tablet: Drop pinmux setting for codec PA gpioChen-Yu Tsai1-10/+0
The old sunxi specific pinctrl bindings are deprecated, in favor of the new generic pinconf bindings. Also, we are moving towards handling GPIO pinmux settings that don't require extra bias or drive strength settings to use the GPIO bindings only. This patch removes the last instance of the sunxi specific pinctrl bindings that use the pinctrl header by dropping the pinmux setting for the audio codec's PA (external amplifier) control GPIO. The pin is pulled down externally. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2017-01-10ARM: dts: sun8i-a23: q8-tablet: Enable internal audio codecChen-Yu Tsai1-0/+23
The A23 Q8 tablets have an internal mono speaker w/ external amp which has a shutdown control tied to a GPIO pin. Both the speaker amp and the headphone jack are tied to the HP output pins. While the speaker is mono, the headset jack is stereo. Unfortunately the driver does not support automatic switching of this. In addition, the headset is DC coupled, or "direct drive" enabled. The headset's microphone is tied to MIC2 with HBIAS providing power. A separate internal microphone is tied to MIC1 with MBIAS providing power.

2016-07-04ARM: dts: sun8i-a?3-q8-tablet.dts: Add full otg supportHans de Goede1-15/+0
Now that we've all the necessary bits in place we can enable full otg support on these tablets. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
2015-10-13ARM: dts: sun8i: Add sun8i-a23-q8-tablet.dts fileHans de Goede1-0/+65
This is a generic dts file for A23 based q8 formfactor tablets, this is intended to replace both sun8i-a23-ippo-q8h-v5.dts and sun8i-a23-ippo-q8h-v1.2.dts (these can be fully dropped after a transition period).
