However, this revert was dependent upon commit e590474768f1 ("driver core: Set fw_devlink=on by default") and without this commit, enabling the ACONNECT is causing resume from system suspend to fail on Jetson TX2. Resume fails because the ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT driver is attempting to power on a power-domain that is provided by the BPMP. Commit e590474768f1 ("driver core: Set fw_devlink=on by default") has since been temporarily reverted while some issues are being investigated. This is causing resume from system suspend on Jetson TX2 to fail again. Rather than disable the ACONNECT driver again, fix this by setting fw_devlink is set to 'on' for Jetson TX2 in the bootargs specified in device-tree.

The SDHCI controller used by each variant is different, however, the current device-tree for both Xavier NX boards have the same SDHCI controller defined as 'mmc0' in the device-tree alias node.

This was based on the observation that the Pine64-LTS has as "push-push" SD card socket, and that the schematic mentions the card detect GPIO. After having received two reports about failing SD card access with that patch, some more research and polls on that subject revealed that there are at least two different versions of the Pine64-LTS out there: - On some boards (including mine) the card detect pin is "stuck" at high, regardless of an microSD card being inserted or not. - On other boards the card-detect is working, but is active-high, by virtue of an explicit inverter circuit, as shown in the schematic. To cover all versions of the board out there, and don't take any chances, let's revert the introduction of the active-low CD GPIO, but let's use the broken-cd property for the Pine64-LTS this time. That should avoid regressions and should work for everyone, even allowing SD card changes now. The SOPine card detect has proven to be working, so let's keep that GPIO in place.
