Subject: [U-Boot] [PATCH v2 3/5] pmic_fsl: Introduce CONFIG_SYS_FSL_PMIC_I2C_LENGTH
Date: Mon, 15 Oct 2012 20:32:08 -0300 [thread overview]
Message-ID: <1350343930-15648-3-git-send-email-festevam@gmail.com> (raw)
In-Reply-To: <1350343930-15648-1-git-send-email-festevam@gmail.com>
From: Fabio Estevam <fabio.estevam@freescale.com>
Introduce CONFIG_SYS_FSL_PMIC_I2C_LENGTH to configure the number of bytes
that are used to communicate with the PMIC via I2C.
Instead of hardcoding the value, pass the number via a config option.
This will be useful for adding support for PMIC MC34704 from Freescale, which
uses only one byte in its I2C protocol.
