2016-11-21media: tc358743: update hdmi to csi-2 driverTomasz Gorochowik
A major part of the driver has been rewritten in order to avoid writing binary blobs to the chip. This version also adds support for more video modes. Input video modes supported: - 1920x1080 @ 60 - 1280x1024 @ 75 - 1280x720 @ 60 - 1024x768 @ 75 - 800x600 @ 75 - 640x480 @ 75 Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Dominik Sliwa <dominik.sliwa@toradex.com>
2016-11-21ADV7280M video decoder with deinterlacer supportWojciech Bieganski
known issues: - decoder outputs PAL (720x576), but the image looks fine only when streamed in 640x576 mode, - vertical synchronisation glitches, - setting queue-size in gstreamer greater than 1 results in blinking image, - every start of streaming requires reloading of the modules Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com> Acked-by: Dominik Sliwa <dominik.sliwa@toradex.com>

2016-09-29compiler-gcc: disable -ftracer for __noclone functionsPaolo Bonzini
commit 95272c29378ee7dc15f43fa2758cb28a5913a06d upstream. -ftracer can duplicate asm blocks causing compilation to fail in noclone functions. For example, KVM declares a global variable in an asm like asm("2: ... \n .pushsection data \n .global vmx_return \n vmx_return: .long 2b"); and -ftracer causes a double declaration.

2016-06-29arm: tegra: initial support for apalis tk1Apalis_TK1_LinuxImageV2.6Beta2_20160701Marcel Ziswiler
This patch adds support for the Toradex Apalis TK1 acomputer on module which can be used on different carrier boards. The module consists of a Tegra TK1 SoC, a PMIC solution, 2 GB of DDR3L RAM, a bunch of level shifters, an eMMC, a TMP451 temperature sensor chip, an I210 gigabit Ethernet controller and a SGTL5000 audio codec. Furthermore, there is a Kinetis MK20DN512 companion micro controller for analogue, CAN and resistive touch functionality which is not yet supported. This is known to boot into either a basic Angstrom/OpenEmbedded/Yocto or L4T/JetPack Ubuntu based image. The following things are known to work to a certain extend: - analogue/digital audio - debug UART1 - DVFS power management incl. low power core migration - eMMC - gigabit Ethernet - GPIOs - HDMI (incl. HDA audio) - I2C - LVDS - PCIe - SATA - SD/MMC cards - temperature sensor - USB host ports The rest is untested.

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.

2016-06-29ARM: 8429/1: disable GCC SRA optimizationArd Biesheuvel
While working on the 32-bit ARM port of UEFI, I noticed a strange corruption in the kernel log. The following snprintf() statement (in drivers/firmware/efi/efi.c:efi_md_typeattr_format()) snprintf(pos, size, "|%3s|%2s|%2s|%2s|%3s|%2s|%2s|%2s|%2s]", was producing the following output in the log: | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | |WB|WT|WC|UC]* | | | | | |WB|WT|WC|UC] |RUN| | | | | | | |UC] |RUN| | | | | | | |UC] As it turns out, this is caused by incorrect code being emitted for the string() function in lib/vsprintf.c. The following code if (!(spec.flags & LEFT)) { while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } } for (i = 0; i < len; ++i) { if (buf < end) *buf = *s; ++buf; ++s; } while (len < spec.field_width--) { if (buf < end) *buf = ' '; ++buf; } when called with len == 0, triggers an issue in the GCC SRA optimization pass (Scalar Replacement of Aggregates), which handles promotion of signed struct members incorrectly. This is a known but as yet unresolved issue. (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65932). In this particular case, it is causing the second while loop to be executed erroneously a single time, causing the additional space characters to be printed. So disable the optimization by passing -fno-ipa-sra.

2016-06-29ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.hBehan Webster
With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the wrong thing (emits code for an externally linkable version of the inline function). In this case using static inline and removing the NULL version of return_address in return_address.c does the right thing.

2016-06-29kernel: add support for gcc 5Sasha Levin
We're missing include/linux/compiler-gcc5.h which is required now because gcc branched off to v5 in trunk. Just copy the relevant bits out of include/linux/compiler-gcc4.h, no new code is added as of now. This fixes a build error when using gcc 5.

2016-06-16mmc: Allow forward compatibility for eMMCRomain Izard
As stated by the eMMC 5.0 specification, a chip should not be rejected only because of the revision stated in the EXT_CSD_REV field of the EXT_CSD register. Remove the control on this value, the control of the CSD_STRUCTURE field should be sufficient to reject future incompatible changes.

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.
