Subject: [PATCH 01/12] arm64: dts: exynos: add USB DWC3 supplies to Espresso board
Date: Sun, 23 Jan 2022 12:16:33 +0100	[thread overview]
Message-ID: <20220123111644.25540-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20220123111644.25540-1-krzysztof.kozlowski@canonical.com>

Add required voltage regulators for USB DWC3 block on Exynos7 Espresso
board.  Due to lack of schematics of Espresso board, the choice of
regulators is approximate.  What bindings call VDD10, for Exynos7 should
be actually called VDD09 (0.9 V).  Use regulators with a matching
voltage range based on vendor sources for Meizu Pro 5 M576 handset (also
with Exynos7420).
