However we do not support parent 1 (an external clock), so use a table to select parent 0 or 2, which are the 2 parents we support. Note this has not been causing any issues sofar, because we start with a parent setting of parent 0, and only ever re-parent to parent 2 (for which we use an index of 1 as we skip parent 1) and with CLK_MUX_INDEX_BIT set we write a value of 2 for index 1. Tested on both a cubietruck (which uses rgmii mode) as well as a cs908 (an a31s board which uses mii mode). Signed-off-by: Hans de Goede Signed-off-by: Maxime Ripard --- Reading git-diff-tree failed
