Hi Valentin, Igor, Are you guys fine with the patch?Do you have a specific question here?
No, I don't. I just wanted to hear the voice of Compulab people. Okay, we haven't waited for time enough, so I just applied patch.
The devicetree additions are mostly identical to their counterparts in the BSP devicetree. The only real exception being that the usdhc1 regulators have been replaced by the sd8787 power sequence, which allows the mmc core to reset the wifi/bt chip (which is not possible with the regulator setup). Note that the sd8787 power sequence binding/driver has only recently been added to Linux (v4.11) and is not present in the BSP kernel. Furthermore, the Bluetooth AMP function is disabled in the BSP kernel by CompuLab [1] for the same reason we do not enable the usdhc1 node in this patch. (We cannot disable it in the driver because, as explained in the commit message, this would yield a regression.)
Thanks for the comments. Shawn
