[PATCH] arm64: dts: renesas: r8a77990: ebisu: Add I2C EEPROM for PMIC

From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: 2021-07-05 12:50:13 

Add a device node for the I2C EEPROM which serves as external storage
for the PMIC setup, as a backup of the internal OTP configuration.

To be queued in renesas-devel for v5.15.
