2017-08-25drm/exynos: mixer: enable NV12MT support for the video planeTobias Jakobi
The video processor supports a tiled version of the NV12 format, known as NV12MT in V4L2 terms. The support was removed in commit 083500baefd5f4c215a5a93aef2492c1aa775828 due to not being a real pixel format, but rather NV12 with a special memory layout. With the introduction of FB modifiers, we can now properly support this format again. Tested with a hacked up modetest from libdrm's test suite on an ODROID-X2 (Exynos4412).

2017-08-25drm/exynos: mixer: fix chroma comment in vp_video_buffer()Tobias Jakobi
The current comment sounds like the division op is done to compensate for some hardware erratum. But the chroma plane having half the height of the luma plane is just the way NV12/NV21 is defined, so clarify this behaviour.

2017-08-25drm/exynos/decon5433: use mode info stored in CRTC to detect i80 modeAndrzej Hajda
Since panel's mode of work is propagated properly from panel to DECON, there is no need to use redundant private device tree property. The only issue with such approach is that check for required interrupts should be postponed until panel communicate its requirements, ie to mode validation phase - mode_valid callback.

2017-08-25drm/exynos: add mode_valid callback to exynos_drmAndrzej Hajda

2017-08-25drm/exynos/dsi: refactor panel detection logicAndrzej Hajda
Description of drm_helper_hpd_irq_event clearly states that drivers supporting hotplug events per connector should use different helper - drm_kms_helper_hotplug_event. To achieve it following changes have been performed: - moved down all DSI ops - they require exynos_dsi_disable function to be defined earlier, - simplified exynos_dsi_detect - there is no real detection, it just returns if panel is attached, - DSI attach/detach callbacks attaches/detaches DRM panel and sets connector status and other context fields accordingly, all this is performed under mutex, as these callbacks are asynchronous.

2017-08-25cpufreq: dt-platdev: Automatically create cpufreq device with OPP v2Viresh Kumar
The initial idea of creating the cpufreq-dt-platdev.c file was to keep a list of platforms that use the "operating-points" (V1) bindings and create cpufreq device for them only, as we weren't sure which platforms would want the device to get created automatically as some had their own cpufreq drivers as well, or wanted to initialize cpufreq after doing some stuff from platform code. But that wasn't the case with platforms using "operating-points-v2" property. We wanted the device to get created automatically without the need of adding them to the whitelist. Though, we will still have some exceptions where we don't want to create the device automatically. Rename the earlier platform list as *whitelist* and create a new *blacklist* as well. The cpufreq-dt device will get created if: - The platform is there in the whitelist OR - The platform has "operating-points-v2" property in CPU0's DT node and isn't part of the blacklist .

2017-08-24Input: ALPS - fix two-finger scroll breakage in right side on ALPS touchpadMasaki Ota
Fixed the issue that two finger scroll does not work correctly on V8 protocol. The cause is that V8 protocol X-coordinate decode is wrong at SS4 PLUS device. I added SS4 PLUS X decode definition. Mote notes: the problem manifests itself by the commit e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)"), where a fix for the V8+ protocol was applied. Although the culprit must have been present beforehand, the two-finger scroll worked casually even with the wrongly reported values by some reason. It got broken by the commit above just because it changed x_max value, and this made libinput correctly figuring the MT events. Since the X coord is reported as falsely doubled, the events on the right-half side go outside the boundary, thus they are no longer handled. This resulted as a broken two-finger scroll. One finger event is decoded differently, and it didn't suffer from this problem. The problem was only about MT events. --tiwai Fixes: e7348396c6d5 ("Input: ALPS - fix V8+ protocol handling (73 03 28)") Signed-off-by: Masaki Ota <masaki.ota@jp.alps.com> Tested-by: Takashi Iwai <tiwai@suse.de> Tested-by: Paul Donohue <linux-kernel@PaulSD.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

In order to prevent QP to get traffic which is not target to its underlay QP, we need to set the underlay QP number as part of the steering matching. Note: When multicast traffic is sent the QPN filtering is done by the firmware as some early step.

2017-08-24qlge: avoid memcpy buffer overflowArnd Bergmann
gcc-8.0.0 (snapshot) points out that we copy a variable-length string into a fixed length field using memcpy() with the destination length, and that ends up copying whatever follows the string: inlined from 'ql_core_dump' at drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:1106:2: drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:708:2: error: 'memcpy' reading 15 bytes from a region of size 14 [-Werror=stringop-overflow=] memcpy(seg_hdr->description, desc, (sizeof(seg_hdr->description)) - 1); Changing it to use strncpy() will instead zero-pad the destination, which seems to be the right thing to do here. The bug is probably harmless, but it seems like a good idea to address it in stable kernels as well, if only for the purpose of building with gcc-8 without warnings.

There is no need to explicitly zero parameters, because the structure requested to be filled already initialized to zeros. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
