Subject: [PATCH 0/3] arm64: dts: renesas: spider: Add I2C and EEPROM support
Date: Thu,  3 Feb 2022 16:26:46 +0100	[thread overview]
Message-ID: <cover.1643898884.git.geert+renesas@glider.be> (raw)

	Hi all,

This patch series adds I2C and EEPROM support for the Renesas R-Car
S4-8 SoC and the Spider development board.

It has been tested by reading /sys/bus/nvmem/devices/*/nvmem.
All three EEPROMs are empty, except for a (different for each
(sub)board) 32-bit value at offset 0x70.
As the AT24 EEPROM driver does not set the I2C_M_DMA_SAFE flag (it uses
regmap), DMA operation was tested by modifying the i2c-rcar driver to
ignore the lack of this flag.

For testing, this series and its dependencies (i2c driver updates,
pinctrl, clk, ...) can be found at[1].

Thanks for your comments!
