2015-02-16V4L: s5c73m3: Use internal firmware by defaultSylwester Nawrocki1-1/+1
Set the boot_from_rom module parameter by default to 1 so the internal sensors's firmware from ROM is used. The external firmware will be loaded only if the module parameter is explicitly set to 0 by the user. This prevents camera stream on failures for some S5C73M3 revisions.

2015-02-12[media] exynos4-is: Fix fimc-lite bayer formatsArun Kumar K1-2/+2
The 10-bit and 12-bit Bayer output formats supported by FIMC-LITE actually use 16 bits where the extra bits are padded with zeros. The patch corrects buffer allocation for these two formats by modifying the depth field. This prevents memory corruption by the output DMA due to insufficient buffer size.

2015-02-12drm: use common drm_gem_dmabuf_release in i915/exynos driversDaniel Vetter3-35/+4
Note that this is slightly tricky since both drivers store their native objects in dma_buf->priv. But both also embed the base drm_gem_object at the first position, so the implicit cast is ok. To use the release helper we need to export it, too.

2015-01-04drm: delete unconsumed pending event list in drm_events_releaseYoungJun Cho1-1/+3
When there are unconsumed pending events, the events are destroyed by calling destroy callback, but the events list are remained, because there is no list_del(). It is possible that the page flip request is handled after drm_events_release() is called and before drm_fb_release(). In this case a drm_pending_event is remained not freed. So exynos driver checks again to remove it in its post close routine. But the file_priv->event_list contains undeleted ones, this can make oops for accessing invalid memory.

2014-12-17i2c: exynos5: Properly use the "noirq" variants of suspend/resumeDoug Anderson1-2/+10
The original code for the exynos i2c controller registered for the "noirq" variants. However during review feedback it was moved to SIMPLE_DEV_PM_OPS without anyone noticing that it meant we were no longer actually "noirq" (despite functions named exynos5_i2c_suspend_noirq and exynos5_i2c_resume_noirq). i2c controllers that might have wakeup sources on them seem to need to resume at noirq time so that the individual drivers can actually read the i2c bus to handle their wakeup. NOTE: I took the original review feedback from Wolfram and added poweroff, thaw, freeze, restore. This patch has only been compile-tested since I don't have all the patches needed to make my machine using this i2c driver actually suspend/resume.

HSI2C module on Exynos5260 differs from current modules in following ways: 1. HSI2C on Exynos5260 has fifo_depth of 16bytes 2. Module needs to be reset as a part of init sequence. Hence, Following changes are involved. 1. Add a new compatible string and Updates the Documentation dt bindings. 2. Introduce a variant struct to support the changes in H/W 3. Reset the module during init. Thus, bringing the module back to default state irrespective of what firmware did with it.

As reported by smatch: drivers/media/dvb-core/dmxdev.c:1091 dvb_demux_poll() warn: variable dereferenced before check 'dmxdevfilter' (see line 1088) This was introduced by changeset d102cac8097c.

2014-11-28s5p-jpeg: Fix possible NULL pointer dereference in s_fmtJacek Anaszewski1-0/+8
Some formats are not supported in encoding or decoding mode for given type of buffer (e.g. V4L2_PIX_FMT_JPEG is supported on output buffer only while in decoding mode). Make S_FMT failing if not suitable format is found. Change-Id: I35c94e38b1b11e2c379f4b2e1f61eedab2bc0a9d Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>

2014-11-27exynos: fimc-is: Internal buffer list cleanupBeata Michalska5-18/+113
As the driver maintaines separate buffer lists per each video device which are beyond control of v4l2/vb2 framework, those lists should be properly handled and cleared once the buffers are no longer available. The changes introduced allow controlling state of each queued buffer and removing it from internal buffer lists when needed.

2014-11-27exynos3: fimc-is: Add support for FIMC IS on Exynos3250Beata Michalska21-922/+3462
The changes introduced provide support for FIMC-IS subsystem avalilable on Exynos3250. They cover the differences in both: the hardware itself as well as the subtle discrepancies between the firmwares controlling the FIMC IS on both SoCs. Regarding the above mentioned firmware variations: the initial driver has been extended with a simplified interface handling those variations thus living the core driver independent of the actual firmware version. Missing code paths have been added to cover handling some of the most probable failures/errors.
