2017-01-06swiotlb: Export swiotlb_max_segment to usersKonrad Rzeszutek Wilk
So they can figure out what is the optimal number of pages that can be contingously stitched together without fear of bounce buffer. We also expose an mechanism for sub-users of SWIOTLB API, such as Xen-SWIOTLB to set the max segment value. And lastly if swiotlb=force is set (which mandates we bounce buffer everything) we set max_segment so at least we can bounce buffer one 4K page instead of a giant 512KB one for which we may not have space.

The gpiod_get* function family does not want the -gpio suffix. Use devm_gpiod_get_index_optional instead of devm_gpiod_get_optional. The descriptor based APIs handle active high/low automatically. The vbus-gpios are output, request enable while getting the gpio. Don't try to get any vbus-gpios for ports outside num-ports. WTF? Big sigh.

2017-01-05usb: musb: dsps: implement clear_ep_rxintr() callbackBin Liu

2017-01-05ACPI / DMAR: Avoid passing NULL to acpi_put_table()Rafael J. Wysocki
Linus reported that commit 174cc7187e6f "ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel" added a new warning on his desktop system: ACPI Warning: Table ffffffff9fe6c0a0, Validation count is zero before decrement which turns out to come from the acpi_put_table() in detect_intel_iommu(). This happens if the DMAR table is not present in which case NULL is passed to acpi_put_table() which doesn't check against that and attempts to handle it regardless. For this reason, check the pointer passed to acpi_put_table() before invoking it. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Tested-by: Paul E.

2017-01-04net: systemport: Pad packet before inserting TSBFlorian Fainelli
Inserting the TSB means adding an extra 8 bytes in front the of packet that is going to be used as metadata information by the TDMA engine, but stripped off, so it does not really help with the packet padding. For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP) we can end-up padding them after the TSB insertion, thus making them 64 bytes, but with the TDMA stripping off the first 8 bytes, they could still be smaller than 64 bytes which is required to ingress the switch. Fix this by swapping the padding and TSB insertion, guaranteeing that the packets have the right sizes.

2017-01-04nvmem: imx-ocotp: Fix wrong register sizeDaniel Schultz
All i.MX6 SoCs have an OCOTP Controller with 4kbit fuses. The i.MX6SL is an exception and has only 2kbit fuses. In the TRM for the i.MX6DQ (IMX6QDRM - Rev 2, 06/2014) the fuses size is described in chapter 46.1.1 with: "32-bit word restricted program and read to 4Kbits of eFuse OTP(512x8)." In the TRM for the i.MX6SL (IMX6SLRM - Rev 2, 06/2015) the fuses size is described in chapter 34.1.1 with: "32-bit word restricted program and read to 2 kbit of eFuse OTP(128x8)." Since the Freescale Linux kernel OCOTP driver works with a fuses size of 2 kbit for the i.MX6SL, it looks like the TRM is wrong and the formula to calculate the correct fuses size has to be 256x8.
