ARM: dts: microchip: sama7d65: Add MCP16502 to sama7d65 curiosity
Add MCP16502 to the sama7d65_curiosity board to control voltages in the MPU. The device is connected to twi 10 interface Signed-off-by: Ryan Wanner <Ryan.Wanner@microchip.com> Link: https://lore.kernel.org/r/60f6b7764227bb42c74404e8ca1388477183b7b5.1743523114.git.Ryan.Wanner@microchip.com [claudiu.beznea: drop regulator-suspend-voltage for ldo2 as it is not needed] Signed-off-by: Claudiu Beznea <claudiu.beznea@tuxon.dev>
