The device controller is the same but it has different PCI ID. Add this new
ID to the driver's list of supported IDs.

Most devices are configured for 32-bit DMA addresses.
Setting the mask to 32-bit here removes the need for the
drivers to do it separately.

Hi,
The original series included patch that adds Braswell PCI ID, but I
send it separately.
The DMA mask caused a problem as our acpi platform code does not
provide anything for us. Instead of trying to fix it in dwc3 I
decided to suggest the first patch in this series where I provide
default DMA
Adds ACPI ID used on newer Intel SoCs.

Hi,
I did some benchmarks to check the maximum transfer rate of a USB-to-SCSI
converter. The converter is USB 1.1, so limited to the 12Mbps full speed
rate. The performance when connected to a USB 3.0 port is significantly
worse than when connected to a USB 2.0 port, about 26.5% slower (0.63MB/sec

This patch series adds a simple macro pm_runtime_last_busy_and_autosuspend()
which invokes pm_runtime_mark_last_busy() and pm_runtime_put_autosuspend()
sequentially. Then we do a tree wide update of current patterns which are
present. As evident from log below this pattern is frequent in the
kernel
Use the new pm_runtime_last_busy_and_autosuspend helper instead of open
coding the same code

Hi,
Regarding the patch I posted to prevent the bus scan of SCM USB-SCSI
converters attempting to scan the converter itself, there is probably a
neater way.
In drivers/scsi/scsi_scan.c, function __scsi_scan_target(), there is:

Hi Felipe and all,
The musb driver musb_host_tx() has the following:

Hi Felipe and Linus,
As you requested, Felipe, I made the translation for the driver's
probing from gpio to gpio_desc. Even if the code is functional, I'm
pretty unhappy about my patch 1, because I lost the "active_low"
notion in the transformation.
I have not found in the gpiolib anything for a
For this preparation, a preliminary cleanup is done :
- convert the probing of pxa27x_udc to gpio_desc.
The conversion is partial because :
- the platform data still provides a gpio number, not a gpio desc
- the "invert" attribute is lost, hence a loss in the translation
- convert
Add support for device-tree device discovery. If devicetree is not
provided, fallback to legacy platform data "discovery".
