2014-03-20zram: promote zram from stagingMinchan Kim1-0/+77
Zram has lived in staging for a LONG LONG time and have been fixed/improved by many contributors so code is clean and stable now. Of course, there are lots of product using zram in real practice. The major TV companys have used zram as swap since two years ago and recently our production team released android smart phone with zram which is used as swap, too and recently Android Kitkat start to use zram for small memory smart phone. And there was a report Google released their ChromeOS with zram, too and cyanogenmod have been used zram long time ago. And I heard some disto have used zram block device for tmpfs. In addition, I saw many report from many other peoples. For example, Lubuntu start to use it. The benefit of zram is very clear. With my experience, one of the benefit was to remove jitter of video application with backgroud memory pressure. It would be effect of efficient memory usage by compression but more issue is whether swap is there or not in the system. Recent mobile platforms have used JAVA so there are many anonymous pages. But embedded system normally are reluctant to use eMMC or SDCard as swap because there is wear-leveling and latency issues so if we do not use swap, it means we can't reclaim anoymous pages and at last, we could encounter OOM kill. :( Although we have real storage as swap, it was a problem, too. Because it sometime ends up making system very unresponsible caused by slow swap storage performance. Quote from Luigi on Google "Since Chrome OS was mentioned: the main reason why we don't use swap to a disk (rotating or SSD) is because it doesn't degrade gracefully and leads to a bad interactive experience. Generally we prefer to manage RAM at a higher level, by transparently killing and restarting processes. But we noticed that zram is fast enough to be competitive with the latter, and it lets us make more efficient use of the available RAM. " and he announced. http://www.spinics.net/lists/linux-mm/msg57717.html Other uses case is to use zram for block device. Zram is block device so anyone can format the block device and mount on it so some guys on the internet start zram as /var/tmp. http://forums.gentoo.org/viewtopic-t-838198-start-0.html Let's promote zram and enhance/maintain it instead of removing.

The PHY framework provides a set of APIs for the PHY drivers to create/destroy a PHY and APIs for the PHY users to obtain a reference to the PHY with or without using phandle. For dt-boot, the PHY drivers should also register *PHY provider* with the framework. PHY drivers should create the PHY by passing id and ops like init, exit, power_on and power_off. This framework is also pm runtime enabled.

2014-03-20V4L: s5k6a3: Add DT binding documentationSylwester Nawrocki1-0/+31
This patch adds binding documentation for the Samsung S5K6A3(YX) raw image sensor. Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> --- The binding of this sensors shows some issue in the generic video-interfaces binding. Namely The video bus type (serial MIPI CSI-2, parallel ITU-R BT.656, etc.) is being determined by the binding parser (v4l2-of.c) depending on what properties are found in an enddpoint node. Please have a look at the data-lanes property description. The sensor supports MIPI CSI-2 and SMIA CCP2 interfaces which both use one data lane. One data lane is everything this sensors supports. During our discussions on the generic bidings in the past I proposed to introduce a property in the endpoint node that would indicate what bus type (standard/protocol) is used, e.g. MIPI CSI-2, ITU-R BT.656, SMIA CCP2, etc. It was argued though that we can well determine bus type based on properties found in the endpoint node. So now in case of this sensor I'm not sure how it can be differentiated whether MIPI CSI-2 or CCP2 bus is used. There is no CCP2 specific generic properties yet. Anyway I'm not really happy there is no property like bus_type that would clearly indicate what data bus type is used. Then would would for instance not specify "data-lanes" in endpoint node just to differentiate between MIPI CSI-2 and the parallel busses. The main issue for this particular binding is that even with data-lanes = <1>; it is still impossible to figure out whether MIPI CSI-2 or SMIA CCP2 data bus is used. So how about introducing, e.g. a string type "bus_type" common property ? I'm considering starting a separate thread for discussing this.

2014-03-20drm/exynos: add device tree support for rotatorChanho Park1-0/+27
The exynos4 platform is only dt-based since 3.10, we should convert driver data and ids to dt-based parsing methods. The rotator driver has a limit table to get size limit of input picture. Each SoCs has slightly different limit value compared with any others. For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have 8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size for its X/Y axis. Thus, we should keep different tables for each of them.

2014-03-20dmabuf-sync: update it to patch v8Inki Dae1-52/+48
- Consider the write-and-then-read ordering. The ordering issue means that a task don't take a lock to the dmabuf so this task would be stalled even though this task requested a lock to the dmabuf between other task unlocked and tries to lock the dmabuf again. For this, it addes a wait event mechanism using only generic APIs, wait_event_timeout and wake_up functions. The below is how to handle the ordering issue using this mechanism: 1. Check if there is a sync object added prior to current task's one. 2. If exists, it unlocks the dmabuf so that other task can take a lock to the dmabuf first. 3. Wait for the wake up event from other task: current task will be waked up when other task unlocks the dmabuf. 4. Take a lock to the dmabuf again. - Update Document - Code cleanups.

2014-03-20f2fs: add remount_fs callback supportNamjae Jeon1-2/+7
Add the f2fs_remount function call which will be used during the filesystem remounting. This function will help us to change the mount options specific to f2fs. Also modify the f2fs background_gc mount option, which will allow the user to dynamically trun on/off the garbage collection in f2fs based on the background_gc value. If background_gc=on, Garbage collection will be turned off & if background_gc=off, Garbage collection will be truned on. By default the garbage collection is on in f2fs. Change Log: v2: Incorporated the review comments by Gu Zheng. Removing the restore part for VFS flags Updating comments with proper flag conditions Display GC background option as ON/OFF Revised conditions to stop GC in case of remount v1: Initial changes for adding remount_fs callback support.

2014-03-20mmc: dw_mmc: Add the ability to set the ciu clock frequencyDoug Anderson1-0/+16
As of now we rely on code outside of the driver to set the ciu clock frequency. There's no reason to do that. Add support for setting up the clock in the driver during probe.
