MPC823: i2c-algo-8xx read interrupt?

[[EMAIL PROTECTED]]

Hi,

When testing with i2c reading an eeprom on a MPC823e I get the message "IIC
read; complete but rbuf empty". IMHO this is because the interrupt in the TX
buffer is enabled intead of the the interrupt of the RX buffer. Is this a bug
or is there a reason behind this?

Best regards,

i2c-algo-8xx.c: cpm_iic_read

Original (with TX interrupt and warning)

        tbdf->cbd_datlen = count + 1;
        tbdf->cbd_sc =
                BD_SC_READY | BD_SC_INTRPT | BD_SC_LAST |
                BD_SC_WRAP | BD_IIC_START;

        rbdf->cbd_datlen = 0;
        rbdf->cbd_bufaddr = __pa(buf);
        rbdf->cbd_sc = BD_SC_EMPTY | BD_SC_WRAP;



With RX interrupt (without warning):

        tbdf->cbd_datlen = count + 1;
        tbdf->cbd_sc =
                BD_SC_READY | BD_SC_LAST |
                BD_SC_WRAP | BD_IIC_START;

        rbdf->cbd_datlen = 0;
        rbdf->cbd_bufaddr = __pa(buf);
        rbdf->cbd_sc = BD_SC_EMPTY | BD_SC_WRAP | BD_SC_INTRPT;
