'<&gpio1 parameters &gpio2 parameters>' and '<&gpio1 parameters>, <&gpio2 parameters>' result in the same DTB, but second format has better source code readability. Also 'dtbs_check' currently uses this format to determine the amount of items specified, so using this syntax is needed to successfully verify the devicetree source against a DT schema format.

Based on linux-gpio discussion [1], it is best practice to make the gpio-line-names unique. Generic names like "[ethernet]" are replaced with the name of the unique signal on the AM3358 SoC ball corresponding to the gpio line. "[NC]" is also renamed to the standard "NC" name to represent "not connected".

There are two variants of the Jetson Xavier NX platform; one has an eMMC and one as a micro SD-card slot. 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.

2021-03-23arm64: tegra: Set fw_devlink=on for Jetson TX2Jon Hunter1-1/+1
Commit 5d25c476f252 ("Revert "arm64: tegra: Disable the ACONNECT for Jetson TX2"") re-enabled the Tegra ADMA and ACONNECT drivers to support audio on Jetson TX2. 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.
