Subject: [PATCH 3/8] board: tq: add support for 16bit eeprom
Date: Wed, 21 Feb 2024 16:03:18 +0100 [thread overview]
Message-ID: <20240221150323.2715164-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20240221150323.2715164-1-s.hauer@pengutronix.de>
Some I2C EEPROMs must be addressed with two bytes. Add the address
argument to pbl_tq_read_eeprom(). The actual EEPROM address will be 0x0
always, but we can use the address to pass I2C_ADDR_16_BIT through it.
