2017-04-04tegra: video: use modedb to specify frame buffer resolutionBhuvanchandra DV
Allow to specify framebuffer videomode using kernel command line parameters. NVIDIAs binary X driver later on picks up those settings and start X with current mode settings, if no EDID data are available. Reused some of the implementation from Stefan's work for modedb support[1] on Tegra20/30 [1] http://git.toradex.com/cgit/linux-toradex.git/commit/?h=tegra-next&id=1d3625dd9903bcc59e2df56836565ebb682948c1 Signed-off-by: Bhuvanchandra DV <bhuvanchandra.dv@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>

2017-04-04regmap-irq: set IRQF_ONESHOT flag to ensure IRQ requestValentin Rothberg
Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. The %irq_flags flag is used to request the threaded IRQ and is also a parameter of the caller. Hence, we cannot be sure that IRQF_ONESHOT is set. This change avoids the potentially missing flag by setting IRQF_ONESHOT when requesting the threaded IRQ.

2016-06-29apalis_t30/tk1: 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, V1.1A, Apalis T30 1GB V1.0A, V1.1A and Apalis T30 1GB IT V1.1A both with blank NVMs as well as iNVMs programmed with Intel's defaults.

2016-05-24video: tegra: host: Fix ch open error handlingArto Merilainen
In case kernel fails to open a channel (e.g. due to inability to allocate hardware context or turn on the device), the channel open function releases the resources that were already allocated successfully. However, currently the error path additionally calls the channel release function for putting the channel pointer after the private data structures have been freed - thereby causing use-after-free memory usage. This patch reworks error handling in channel open to release channel without risking usage of already freed memory.
