Subject: [PATCH 06/11] ARM: dts: exynos: add panel supply in Tiny4412
Date:   Fri, 20 Jan 2023 16:53:59 +0100

The simple panel should have a supply.  Provide a stub, as the board DTS
does not have a PMIC node, to silence warning:

  exynos4412-tiny4412.dtb: panel: 'power-supply' is a required property
