Subject: [U-Boot] A question about unconfigured pads check in omap24xx_i2c
Date: Wed, 06 Nov 2013 14:12:27 +0200 [thread overview]
Message-ID: <527A322B.6070703@compulab.co.il> (raw)
In drivers/i2c/omap24xx_i2c.c there are a few checks that attempt to
detect unconfigured pads for the i2c bus in use. These checks are
all in the form of
if (status == I2C_STAT_XRDY) {
printf("unconfigured pads\n");
return -1;
}
This check seems peculiar to me since the meaning of I2C_STAT_XRDY is
that new data is requested for transmission. Why is that indication that
the bus is not padconf'd for I2C?
