Not all OMAP boards will use the same clock for the external device.Are you saying different OMAP boards will use different Internal clocks? Or different OMAP boards will use a single Internal clock or an external one.All I was saying is that one board can use for example auxclk1 whereas another one can use auxclk3, both generated by OMAP for the same PHY configuration.Ok, so lets keep DT aside for a while. How would something like this work in a non-DT world? Would the driver then be able to do a clk_get(dev, "main_clk"); and get say auxclk1 on one board and auxclk3 on another?Yes, all you need to do is specify an alias to the clock in the board file.
Can we then create a special board specific node for panda and do similar things from DT? See a similar discussion below on how to handle the gpio_request() we had as part of board files http://www.spinics.net/lists/linux-omap/msg85248.html
e.g. in board 1 file
clk_add_alias("main_clk", "phy.1", "auxclk1_ck", NULL);
in board 2 file
clk_add_alias("main_clk", "phy.1", "auxclk3_ck", NULL);
