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.

2014-11-27exynos: mipi-csis: Fix clock handling for exynos3250Beata Michalska1-13/+29
In case of Exynos3250 only gate clock is required thus all the remaining mipi-csis clocks are considered as optional. Signed-off-by: Beata Michalska <b.michalska@samsung.com> Change-Id: Ibadffe49739add39f156737cbb723b24a5dd4ff5

2014-11-27exynos5-is: Make sclk_bayer clock handling optionalSylwester Nawrocki1-11/+16
There is no sclk_bayer clock on exynos3250. Some flag at the variant data could be added later to handle properly error from clk calls. Change-Id: I249169e1a7c451db6805dee7d01dd95816f329e0 Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>
2014-11-27exynos5-is: Allow initialization when fimc-is is a master nodeSylwester Nawrocki7-113/+222
Change platform sub-devices registration method so the driver can support exynos3250 DT binding, i.e. initialize when fimc-is is the complex root node, not "camera". This also merges exynos5-fimc-is and exynos-mdevice into single kernel module called exynos-iss.ko.

2014-11-27[media] Add driver for exynos5 FIMC-IS subsystemArun Kumar K22-0/+7243
This driver is for the FIMC-IS IP available in Samsung Exynos5 SoC onwards. exynos5-fimc-is: Add common driver header files This patch adds all the common header files used by the fimc-is driver. It includes the commands for interfacing with the firmware and error codes from IS firmware, metadata and command parameter definitions. exynos5-fimc-is: Add register definition and context header This patch adds the register definition file for the fimc-is driver and also the header file containing the main context for the driver. exynos5-fimc-is: Add isp subdev fimc-is driver takes video data input from the ISP video node which is added in this patch. This node accepts Bayer input buffers which is given from the IS sensors. exynos5-fimc-is: Add scaler subdev FIMC-IS has two hardware scalers named as scaler-codec and scaler-preview. This patch adds the common code handling the video nodes and subdevs of both the scalers. exynos5-fimc-is: Add sensor interface Some sensors to be used with fimc-is are exclusively controlled by the fimc-is firmware. This minimal sensor driver provides the required info for the firmware to configure the sensors sitting on I2C bus. exynos5-fimc-is: Add the hardware pipeline control This patch adds the crucial hardware pipeline control for the fimc-is driver. All the subdev nodes will call this pipeline interfaces to reach the hardware. Responsibilities of this module involves configuring and maintaining the hardware pipeline involving multiple sub-ips like ISP, DRC, Scalers, ODC, 3DNR, FD etc. exynos5-fimc-is: Add the hardware interface module The hardware interface module finally sends the commands to the FIMC-IS firmware and runs the interrupt handler for getting the responses.
