+
+From: Peter Chen <peter.chen@nxp.com>
+
+commit 7480d912d549f414e0ce39331870899e89a5598c upstream.
+
+According to xHCI ch4.20 Scratchpad Buffers, the Scratchpad
+Buffer needs to be zeroed.
+
+ ...
+ The following operations take place to allocate
+ Scratchpad Buffers to the xHC:
+ ...
+ b. Software clears the Scratchpad Buffer to '0'

+Subject: usb: host: xhci-plat: propagate return value of platform_get_irq()
+
+From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
+
+commit 4b148d5144d64ee135b8924350cb0b3a7fd21150 upstream.
+
+platform_get_irq() returns an error code, but the xhci-plat driver
+ignores it and always returns -ENODEV. This is not correct, and
+prevents -EPROBE_DEFER from being propagated properly.

+Subject: xhci: remove GFP_DMA flag from allocation
+
+From: Matthias Lange <matthias.lange@kernkonzept.com>
+
+commit 5db851cf20857c5504b146046e97cb7781f2a743 upstream.
+
+There is no reason to restrict allocations to the first 16MB ISA DMA
+addresses.
+
+It is causing problems in a virtualization setup with enabled IOMMU
+(x86_64). The result is that USB is not working in the VM.
