[ Upstream commit 26d5bb9e4c4b541c475751e015072eb2cbf70d15 ] FMAN DMA read or writes under heavy traffic load may cause FMAN internal resource leak; thus stopping further packet processing. The FMAN internal queue can overflow when FMAN splits single read or write transactions into multiple smaller transactions such that more than 17 AXI transactions are in flight from FMAN to interconnect. When the FMAN internal queue overflows, it can stall further packet processing. The issue can occur with any one of the following three conditions: 1. FMAN AXI transaction crosses 4K address boundary (Errata A010022) 2. FMAN DMA address for an AXI transaction is not 16 byte aligned, i.e. the last 4 bits of an address are non-zero 3. Scatter Gather (SG) frames have more than one SG buffer in the SG list and any one of the buffers, except the last buffer in the SG list has data size that is not a multiple of 16 bytes, i.e., other than 16, 32, 48, 64, etc. With any one of the above three conditions present, there is likelihood of stalled FMAN packet processing, especially under stress with multiple ports injecting line-rate traffic. To avoid situations that stall FMAN packet processing, all of the above three conditions must be avoided; therefore, configure the system with the following rules: 1. Frame buffers must not span a 4KB address boundary, unless the frame start address is 256 byte aligned 2. All FMAN DMA start addresses (for example, BMAN buffer address, FD[address] + FD[offset]) are 16B aligned 3. SG table and buffer addresses are 16B aligned and the size of SG buffers are multiple of 16 bytes, except for the last SG buffer that can be of any size. Additional workaround notes: - Address alignment of 64 bytes is recommended for maximally efficient system bus transactions (although 16 byte alignment is sufficient to avoid the stall condition) - To support frame sizes that are larger than 4K bytes, there are two options: 1. Large single buffer frames that span a 4KB page boundary can be converted into SG frames to avoid transaction splits at the 4KB boundary, 2. Align the large single buffer to 256B address boundaries, ensure that the frame address plus offset is 256B aligned. - If software generated SG frames have buffers that are unaligned and with random non-multiple of 16 byte lengths, before transmitting such frames via FMAN, frames will need to be copied into a new single buffer or multiple buffer SG frame that is compliant with the three rules listed above.

commit 42bf02ec6e420e541af9a47437d0bdf961ca2972 upstream Some platforms (e.g. TI's DRA7 USB2 instance) have more trouble with the metastability workaround as it supports only a High-Speed PHY and the PHY can enter into an Erratic state [1] when the controller is set in SuperSpeed mode as part of the metastability workaround. This causes upto 2 seconds delay in enumeration on DRA7's USB2 instance in gadget mode. If these platforms can be better off without the workaround, provide a device tree property to suggest that so the workaround is avoided.

2018-12-01can: hi311x: Use level-triggered interruptLukas Wunner1-1/+1
commit f164d0204b1156a7e0d8d1622c1a8d25752befec upstream. If the hi3110 shares the SPI bus with another traffic-intensive device and packets are received in high volume (by a separate machine sending with "cangen -g 0 -i -x"), reception stops after a few minutes and the counter in /proc/interrupts stops incrementing. Bus state is "active". Bringing the interface down and back up reconvenes the reception. The issue is not observed when the hi3110 is the sole device on the SPI bus. Using a level-triggered interrupt makes the issue go away and lets the hi3110 successfully receive 2 GByte over the course of 5 days while a ks8851 Ethernet chip on the same SPI bus handles 6 GByte of traffic. Unfortunately the hi3110 datasheet is mum on the trigger type. The pin description on page 3 only specifies the polarity (active high): http://www.holtic.com/documents/371-hi-3110_v-rev-kpdf.do Cc: Mathias Duckeck <m.duckeck@kunbus.de> Cc: Akshay Bhat <akshay.bhat@timesys.com> Cc: Casey Fitzpatrick <casey.fitzpatrick@timesys.com> Signed-off-by: Lukas Wunner <lukas@wunner.de> Cc: linux-stable <stable@vger.kernel.org> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-12-14dt-bindings: usb: fix reg-property port-number rangeJohan Hovold1-1/+1
[ Upstream commit f42ae7b0540937e00fe005812997f126aaac4bc2 ] The USB hub port-number range for USB 2.0 is 1-255 and not 1-31 which reflects an arbitrary limit set by the current Linux implementation. Note that for USB 3.1 hubs the valid range is 1-15. Increase the documented valid range in the binding to 255, which is the maximum allowed by the specifications.

[ Upstream commit e20824e944c3bf4352fcd8d9f446c41b53901e7b ] While the new family-specific compatible values introduced by commit 6f54cc1adcc8957f ("devicetree: bindings: R-Car Gen2 CMT0 and CMT1 bindings") use the recommended order "<vendor>,<family>-<device>", the new SoC-specific compatible values still use the old and deprecated order "<vendor>,<device>-<soc>". Switch the SoC-specific compatible values to the recommended order while there are no upstream users of these compatible values yet.

2017-12-05hwmon: (jc42) optionally try to disable the SMBUS timeoutPeter Rosin1-0/+4
commit 68615eb01f82256c19e41967bfb3eef902f77033 upstream. With a nxp,se97 chip on an atmel sama5d31 board, the I2C adapter driver is not always capable of avoiding the 25-35 ms timeout as specified by the SMBUS protocol. This may cause silent corruption of the last bit of any transfer, e.g. a one is read instead of a zero if the sensor chip times out. This also affects the eeprom half of the nxp-se97 chip, where this silent corruption was originally noticed. Other I2C adapters probably suffer similar issues, e.g. bit-banging comes to mind as risky... The SMBUS register in the nxp chip is not a standard Jedec register, but it is not special to the nxp chips either, at least the atmel chips have the same mechanism. Therefore, do not special case this on the manufacturer, it is opt-in via the device property anyway.

Two major groups stand out: - Some pinctril dts/dtsi changes for stm32 due to a new driver being merged during the merge window, and this aligns the DT contents between the old format and the new. This could arguably be moved to the next merge window but it also seemed relatively harmless to include now. - Amlogic/meson had driver changes merged that required devicetree changes to avoid functional/performance regressions. I've already asked them to be more careful about this going forward, and making sure drivers are compatible with older DTs when they make these kind of changes.

The binding documentation is updating accordingly. Without this patch the kernel hand during boot if the mvpp2.2 network driver was not present in the kernel. Indeed the clock needed by the xenon controller was set by the network driver.
