PATCH 4/5 ARM: dts: sun5i: Add dts file for the Empire Electronix D709 tablet

In reply to Hans de Goede

The Empire Electronix D709 tablet is a fairly standard 7" A13 tablet, featuring usb-wifi, a micro-sd slot, micro-usb otg and headphone jack.

Empire Electronix is written on the back of the tablet, the D709 model info can be found in the about tablet menu in android.

The PCB has no markings to speak of.

This dts file does not add support for the ft5x touchscreen found at i2c bus 1, addr 0x38, irq PG11, because it does not work out of the box. It seems it has been flashed with the wrong firmware and needs to have alternative firmware uploaded at boot to make the touchscreen work properly, when hot-booting from android into an upstream kernel the touchscreen does work.

The Memsic MXC622X accelerometer at i2c bus 1, addr 0x15 also is not enabled as there is no driver for it.

The contents seem the same as sun5i-q8-common.dtsi and sun5i-a13-q8-tablet.dts. Any chance you could use those instead?

On the side, any thoughts on how to handle the differences between various "Q8" tablets, like different I2C-based sensors and WiFi chips?

I'm asking because with Maxime's couple-regulator we should be able to get the RTL8723BS on the Q8 A23/33 v1.5 working.

Given the special needs of the touchscreen I do not think that that is a good idea.

Quoted 2 lines

On the side, any thoughts on how to handle the differences between various "Q8" tablets, like different I2C-based sensors and WiFi chips?

For i2c based sensors the plan is to use devicetree overlays + an in kernel overlay manager which probes the i2c bus (checking known touchscreen / accelerometer addresses) and then picks the right touchscreen + accelerometer overlays.

Wifi is somewhat more tricky I must admit, esp. since there seem to be q8 a23 based tablet variants with usb wifi and others with sdio wifi. Since both busses are discoverable I'm tempted to just enable both in devicetree, and let the kernel probe and see what is actually there. This assume that the way the wifichip is powered is the same on all boards, or at least that it is safe to enable the necessary regulators on all boards ...

Quoted 2 lines

I'm asking because with Maxime's couple-regulator we should be able to get the RTL8723BS on the Q8 A23/33 v1.5 working.

So this means enabled the sdio controller (should be safe on all boards?) and enabling 2 regulators to power the wifi-chip. I think it will be safe to do this even on boards where those regulators are not used, what do you think ?

Hans

If nothing is attached to those regulators (which I expect to be the case when they are not used to power wifi) then I would expect the drain to be minimal, my biggest worry is some board having tied these to ground, but I don't think that is very likely.

AFAIK the AXP datasheets mention that unused DCDC outputs should be left floating. Not sure if this applies to LDO outputs as well. But any used outputs would have a bypass capacitor.

From the board designs I've seen, this seems to be the common case.

I'm not an electrical engineer, but I think we're covered here.

Another thing we need to deal with is the different power sequencing requirements for the different SDIO chips.

In my experience there are not that much sequences, as simply making sure all necessary resources are one before probing the sdio bus, I have yet to see a case where the order in which the resources are enabled matters.
