[PATCH 6.6 151/676] arm64: dts: mediatek: Add ADC node on MT6357, MT6358, MT6359 PMICs

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

[ Upstream commit b0a4ce81f327eae06c1088f1a437edc48a94a3e8 ]

Add support for the ADC on MT6357/8/9 and keep it default enabled
as this IP is always present on those PMICs.
Users may use different IIO channels depending on board-specific
routing.
