Subject: [U-Boot] question about software i2c multi instance
Date: Fri, 20 Mar 2015 17:44:12 +0800	[thread overview]
Message-ID: <550BEBEC.7060609@atmel.com> (raw)

Hi Heiko,
   After check the software i2c code, I found it can not support multi 
instances, although it has I2C_SOFT_DECLARATIONS2, 
I2C_SOFT_DECLARATIONS3, I2C_SOFT_DECLARATIONS4.
   Because, when do GPIO operation, there is only one pair of 
CONFIG_SOFT_I2C_GPIO_SCL and CONFIG_SOFT_I2C_GPIO_SDA.
   So, if want to support multi instances, it needs to extend the GPIO 
configuration for SCL/SDA, am I right?

   Thanks.

Best Regards,
Bo Shen
