First one [1] was reverted since it didn't resolve the issue\ncomprehensively. Second one [2] was rejected by internal review.\n\nThe LPSS DMA controller does not have neither _PS0 nor _PS3 method. Moreover it\ncan be powered off automatically whenever the last LPSS device goes down. In\ncase of no power any access to the DMA controller will hang the system. The\nbehaviour is reproduced on some HP laptops based on Intel BayTrail [3,4] as\nwell as on ASuS T100TA transformer.\n\nPower on the LPSS island through the registers accessible in a specific way.\n\n[1] http://www.spinics.net/lists/linux-acpi/msg53963.html\n[2] https://bugzilla.redhat.com/attachment.cgi?id=1066779&action=diff\n[3] https://bugzilla.redhat.com/show_bug.cgi?id=1184273\n[4] http://www.spinics.net/lists/dmaengine/msg01514.html\n\nSigned-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>\nSigned-off-by: Rafael J.
