Subject: [PATCH v2] arm64: defconfig: Enable SC7180 interconnect driver

From: AngeloGioacchino Del Regno <[email protected]>

On SC7180 device trees, almost all of the nodes are declaring
interconnect properties, including the QUP nodes: at least on
some machines, leaving this configuration option disabled, or
as a module, the kernel appears to hang while initializing the
QUP node containing the UART device.

To solve this issue, enable the interconnect driver for this
SoC as built-in.

Hi Bjorn, could you pick this, as well as
https://lore.kernel.org/all/[email protected]/,
up for arm64-defconfig-for-5.18?

Both series apply cleanly on that branch. Thanks!

N?colas
