2014-07-21mmc: tegra: use 1.8V quirk only on affected instancesStefan Agner
The 1.8V quirk also affected the internal eMMC which disabled newer modes such as SDR50, SDR104 and DDR50. This in turn lead to an out of spec usage since the clock was still 50MHz. By creating a no_1v8 field in the platform data we can now enable this work around on a per-instance basis. Hence we enable the quirk only on the controllers which are connected to the external SD-slots.
2014-07-16arm: tegra3: PCIe Clock and Reset Conform to SpecificationEric Yuen
PCIe Reset line must be asserted for at least 100us after clock is enabled. PEX 2 Controller Register fix, offsets are not at constant intervals.

Force round down in division calculating required logo height as preceding code did round up as follows: logo_lines = DIV_ROUND_UP(logo_height, vc->vc_font.height); Which resulted in no boot-logo shown at all due to not enough lines being available.

2014-07-08media: vi driver on Colibri T20 is working againWojciech Bieganski

2014-05-09colibri t20/t30: add spi controller platform data for hw csMarcel Ziswiler
Add SPI controller platform data required for use of hardware chip selects. While at it pull-up SPI chip select pin due to NVIDIA's designers taking the term chip select a little too personal: they indeed only select a chip otherwise all the chip select pins are just left floating!
2014-05-09colibri t20/t30: clarify mcp2515 resetMarcel Ziswiler
The MCP2515 on the Colibri EvalBoard V3.1a actually uses regular system reset aka RESET_OUT# on SODIMM 87 to reset the MCP2515. Therefore clean-up resp. remove any MECS Tellurium legacy in that respect. While at it adjust copyright year, re-order some include, clean-up some struct spacing, re-order clocks and improve some comments.
2014-05-08media: enabled CSI mode in AS0260 camera driverWojciech Bieganski
2014-04-29arm: tegra: dc: disable dc when framebuffer off detectedStefan Agner
Don't initialize the whole display controller (dc) when framebuffer mode is set to off. This avoids creation of the /dev/tegra_dc_x device. The tegra X driver requires for each tegra_dc_x device an framebuffer device with the same id. This patch avoids creation of both, which makes the tegra X driver load correctly. Note: Turning off tegrafb0 still leads to kernel crash due to hard coded device enumeration.
2014-04-22can: mcp251x: fix locking in BERR counter functionalityMarcel Ziswiler
Symptoms: The interface stops receiving CAN frames when reception of CAN frame and call to the introduced get_berr_counter function coincide. Reproduction: Ip requests, among others, the berr field for the can interfaces. NOTE that it does so even if called as 'ip link show lo', as interface-based filtering is only done after the system calls to receive interface information. Run candump on a MCP-based can interface that has a lot of traffic (via 'cangen -g1' on another can node). On the system with the MCP chip, run while /bin/true; do ip link > /dev/null ; done; Reception of CAN-frames (as shown by candump) will cease within seconds. This issue got introduced by commit 1b59090a47101b4bf379d2c35986ad3f0bcb2aa1 as access to the SPI registers of the MCP251x were not locked. Issue report and patch courtesy David R.

2014-03-31apalis_t30: igb: no nvm and Ethernet MAC address handlingMarcel Ziswiler
Springville/i211 with a blank Flash/iNVM use different PCI IDs. Extend the driver to load despite i210/i211 data sheets claiming tools only, not for driver. Only warn rather than fail on NVM validation failures on Apalis T30. Revise Ethernet MAC address assignment: should now handle up to two instances of custom user MACs (2nd one with a 0x100000 offset). This way customer does not have to worry about NVM on a secondary Ethernet on the carrier board and still gets a valid official MAC address from us (e.g. analogous to how we did it on our Protea carrier board). Use the Toradex OUI as default MAC address if no valid one is encountered. Tested on samples of Apalis T30 2GB V1.0B, V1.0C and Apalis T30 1GB V1.0A both with blank NVMs as well as iNVMs programmed with Intel's defaults.

2014-03-31ethtool: Introduce a method for getting time stamping capabilities.Richard Cochran
This commit adds a new ethtool ioctl that exposes the SO_TIMESTAMPING capabilities of a network interface. In addition, user space programs can use this ioctl to discover the PTP Hardware Clock (PHC) device associated with the interface. Since software receive time stamps are handled by the stack, the generic ethtool code can answer the query correctly in case the MAC or PHY drivers lack special time stamping features.

2014-03-10tty: serial: tegra: initialize with lower baudrateStefan Agner
While setup, there is a time the serial port is running on a predefined speed (115200). When data arrived during this phase at a lower baudrate (e.g. 9600), a lot of overrun and break error messages were shown. Due to those messages, the terminal setup never finished, and thus never reached the selected baudrate (e.g. 9600). By choosing a lower baudrate at the startup (9600), a lot less (if any at all) messages are shown and those initialization always succeeds. Another solution would be to disable those messages completely. However, while normal mode its good to have those UART error messages.
