2020-03-20drm/etnaviv: request pages from DMA32 zone when neededLucas Stach
Some Vivante GPUs are found in systems that have interconnects restricted to 32 address bits, but may have system memory mapped above the 4GB mark. As this region isn't accessible to the GPU via DMA any GPU memory allocated in the upper part needs to go through SWIOTLB bounce buffering. This kills performance if it happens too often, as well as overrunning the available bounce buffer space, as the GPU buffer may stay mapped for a long time. Avoid bounce buffering by checking the addressing restrictions. If the GPU is unable to access memory above the 4GB mark, request our SHM buffers to be located in the DMA32 zone.

2020-03-20i2c: dev: Fix the race between the release of i2c_dev and cdevKevin Hao
The struct cdev is embedded in the struct i2c_dev. In the current code, we would free the i2c_dev struct directly in put_i2c_dev(), but the cdev is manged by a kobject, and the release of it is not predictable. So it is very possible that the i2c_dev is freed before the cdev is entirely released. We can easily get the following call trace with CONFIG_DEBUG_KOBJECT_RELEASE and CONFIG_DEBUG_OBJECTS_TIMERS enabled.

2020-03-20net: dsa: sja1105: Add support for the SGMII portVladimir Oltean
SJA1105 switches R and S have one SerDes port with an 802.3z quasi-compatible PCS, hardwired on port 4. The other ports are still MII/RMII/RGMII. The PCS performs rate adaptation to lower link speeds; the MAC on this port is hardwired at gigabit. Only full duplex is supported. The SGMII port can be configured as part of the static config tables, as well as through a dedicated SPI address region for its pseudo-clause-22 registers. However it looks like the static configuration is not able to change some out-of-reset values (like the value of MII_BMCR), so at the end of the day, having code for it is utterly pointless. We are just going to use the pseudo-C22 interface. Because the PCS gets reset when the switch resets, we have to add even more restoration logic to sja1105_static_config_reload, otherwise the SGMII port breaks after operations such as enabling PTP timestamping which require a switch reset. >From PHYLINK perspective, the switch supports *only* SGMII (it doesn't support 1000Base-X). It also doesn't expose access to the raw config word for in-band AN in registers MII_ADV/MII_LPA. It is able to work in the following modes: - Forced speed - SGMII in-band AN slave (speed received from PHY) - SGMII in-band AN master (acting as a PHY) The latter mode is not supported by this patch. It is even unclear to me how that would be described. There is some code for it left in the patch, but 'an_master' is always passed as false.

2020-03-20staging: mt7621-pci-phy: avoid to create to different phys for a dual port oneSergio Paracuellos
This soc has two phy's for the pcie one of them using just a different register for settig it up but sharing all the rest of the config. Until now we was presenting this schema as three different phy's in the device tree using the 'phy-cells' node property to discriminate an index and setting up a complete phy for the dual port index. This sometimes worked properly but reconfiguring the same registers twice presents sometimes some unstable pcie links and the ports was not properly being detected. The problems only appears on hard resets and soft resets was properly working. Instead of having this schema just set two phy's in the device ree and use the 'phy-cells' property to say if the port has or not a dual port. Doing this configuration and set up becomes easier, LOC is decreased and the behaviour also gets deterministic with properly and stable pcie links in both hard and soft resets.

2020-03-20phy: phy-mtk-tphy: add a new reference clockChunfeng Yun
Usually the digital and analog phys use the same reference clock, but some platforms have two separate reference clocks for each of them, so add another optional clock to support them. In order to keep the clock names consistent with PHY IP's, change the da_ref for analog phy and ref clock for digital phy.

2020-03-20phy: uniphier-pcie: Add SoC-dependent phy-mode function supportKunihiko Hayashi
Since this phy is shared by multiple devices including USB and PCIe, it is necessary to determine which device use this phy. This patch adds SoC-dependent functions to determine a device using this phy. When there is 'socionext,syscon' property in the pcie-phy node, the driver calls SoC-dependt function instead of checking .has_syscon in SoC-dependent data. The function configures the system controller to use phy for PCIe. Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
