I will implement as your comment. However , because adding 1 to the+ param = i2c_dw_read_comp_param(dev);
+ tx_fifo_depth = ((param >> 16) & 0xff) + 1;
+ rx_fifo_depth = ((param >> 8) & 0xff) + 1;
+ if (!dev->tx_fifo_depth) {
+ dev->tx_fifo_depth = tx_fifo_depth;
+ dev->rx_fifo_depth = rx_fifo_depth;
+ dev->adapter.nr = id;
+ } else if (tx_fifo_depth > 1) {
This makes sense now, though I would add a comment here and use >= 2 to
reflect datasheet.
/*

* driver provided.
*/
value , can i use > 2 or >=3 ?
