Should this really be in this patch ?
As I change the binding parsing, the stm32mp1 will don't work without this
patch.
I make a commun patch only to allow bisec, but I can split the serie with 2
patches.

Can't you just read directly into platdata->tx_fifo_sz_array[] below, and thus drop this temporary variable ?
It was the case in in my first internal version.
if (platdata->tx_fifo_sz_nb) { ret = dev_read_u32_array(dev, "g-tx-fifo-size", &platdata->tx_fifo_sz_array, platdata->tx_fifo_sz_nb); if (ret) return ret; }
And I add it to avoid the warning / potential issue:

Try
ret = dev_read_u32_array(dev, "g-tx-fifo-size",
&platdata->tx_fifo_sz_array,
platdata->tx_fifo_sz_array, platdata->tx_fifo_sz_nb);
You are right, it is working I don't double check the type of the buffer :-< => I will push update in V2
btw is this fix for current release or next ?
I hope it for the v2019.07 (as it is only impact the stm32mp1 arch/board). But it is not blocking.
OK
