2021-03-11arm64: dts: qcom: sc7180: Avoid glitching SPI CS at bootup on trogdorDouglas Anderson
At boot time the following happens: 1. Device core gets ready to probe our SPI driver. 2. Device core applies SPI controller's "default" pinctrl. 3. Device core calls the SPI driver's probe() function which will eventually setup the chip select GPIO as "unasserted". Thinking about the above, we can find: a) For SPI devices that the BIOS inits (Cr50 and EC), the BIOS would have had them configured as "GENI" pins and not as "GPIO" pins. b) It turns out that our BIOS also happens to init these pins as "output" (even though it doesn't need to since they're not muxed as GPIO) but leaves them at the default state of "low". c) As soon as we apply the "default" chip select it'll switch the function to GPIO and stop driving the chip select high (which is how "GENI" was driving it) and start driving it low. d) As of commit 9378f46040be ("UPSTREAM: spi: spi-geni-qcom: Use the new method of gpio CS control"), when the SPI core inits things it inits the GPIO to be "deasserted". Prior to that commit the GPIO was left untouched until first use. e) When the first transaction happens we'll assert the chip select and then deassert it after done. So before the commit to change us to use gpio descriptors we used to have a _really long_ assertion of chip select before our first transaction (because it got pulled down and then the first "assert" was a no-op). That wasn't great but (apparently) didn't cause any real harm. After the commit to change us to use gpio descriptors we end up glitching the chip select line during probe. It would go low and then high with no data transferred. The other side ought to be robust against this, but it certainly could cause some confusion. It's known to at least cause an error message on the EC console and it's believed that, under certain timing conditions, it could be getting the EC into a confused state causing the EC driver to fail to probe. Let's fix things to avoid the glitch. We'll add an extra pinctrl entry that sets the value of the pin to output high (CS deasserted) before doing anything else. We'll do this in its own pinctrl node that comes before the normal pinctrl entries to ensure that the order is correct and that this gets applied before the mux change. This change is in the trogdor board file rather than in the SoC dtsi file because chip select polarity can be different depending on what's hooked up and it doesn't feel worth it to spam the SoC dtsi file with both options. The board file would need to pick the right one anyway.

This is a trogdor variant. This is mostly a grab from the downstream tree with notable exceptions: - I skip -rev0. This was a super early build and there's no advantage of long term support. - I remove sound node since sound hasn't landed upstream yet.
