2013-11-22workqueue: convert BUG_ON()s in __queue_delayed_work() to WARN_ON_ONCE()sTejun Heo
commit fc4b514f2727f74a4587c31db87e0e93465518c3 upstream. 8852aac25e ("workqueue: mod_delayed_work_on() shouldn't queue timer on 0 delay") unexpectedly uncovered a very nasty abuse of delayed_work in megaraid - it allocated work_struct, casted it to delayed_work and then pass that into queue_delayed_work(). Previously, this was okay because 0 @delay short-circuited to queue_work() before doing anything with delayed_work. 8852aac25e moved 0 @delay test into __queue_delayed_work() after sanity check on delayed_work making megaraid trigger BUG_ON(). Although megaraid is already fixed by c1d390d8e6 ("megaraid: fix BUG_ON() from incorrect use of delayed work"), this patch converts BUG_ON()s in __queue_delayed_work() to WARN_ON_ONCE()s so that such abusers, if there are more, trigger warning but don't crash the machine.

2013-10-23ENGR00278452 PU: fix system hang if run Audio loop testRobin Gong
cpufreq and pu power management will oprate the same register, it looks should keep them operating in order not concurrent. Then use the cpufreq mutex in xPU driver to make sure. Another code bug is in pu power management which base regulator framework, we set the reister directly not regulator, then there is the chance set_volatage will miss the chance if this time voltage setting as the last time setting before PU disable, but we have to do this, so add regulator_sync_voltage to force sync the voltage setting. The drawback is setting twice... Note: This patch is temporary and supposed to be replaced it once we find the root cause. Signed-off-by: Robin Gong <b38343@freescale.com> Acked-by: Jason Liu

This patch adds the re-initialization and the sanity check. Also, add the pointer check for memcpy because the destination may be NULL on UERSPTR mode. Signed-off-by: Robby Cai <R63905@freescale.com>

2013-08-15ENGR00275391 i.mx6d/q: disable the double linefill feature of PL310Jason Liu
The L2 cache controller(PL310) version on the i.MX6D/Q is r3p1-50rel0 The L2 cache controller(PL310) version on the i.MX6DL/SOLO/SL is r3p2 But according to ARM PL310 errata: 752271 ID: 752271: Double linefill feature can cause data corruption Fault Status: Present in: r3p0, r3p1, r3p1-50rel0. Fixed in r3p2 Workaround: The only workaround to this erratum is to disable the double linefill feature. This is the default behavior. [in the commit:c483abdca0011c1342bad42f16925dd5a2c7c091] ENGR00271977-1 imx6_defconfig: enable PL310_ERRATA_769419 There is one error in the commit log, the correct PL310 version in i.MX6DL/SOLO should be r3p2, not r3p1-50rel0. so, PL310_ERRATA_769419, will not apply to i.MX6DL/SOLO. But since we build one image to support both i.MX6Q and i.MX6DL/SOLO, the ideal solution is to manage this errata in dynamic way. Someone did post the patches here: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/145593.html As the discussion on the above link, Russell King, the ARM arch maintainer said: "As I already said, there is _no_ point making the barrier conditional; it's probably more expensive to make it conditional than just to execute it every time. But we still might as well optimize it away if we are running _only_ on platforms which _do_ _not_ have that errata." So, we will turn on the PL310_ERRATA_769419 on both i.MX6D/Q and i.MX6DL/SOLO.

V4L2_PIX_FMT_YUYV is the original format from camera and the source format for CSI. This format may be needed on Android to do CSC before encoding. We can now choose V4L2_PIX_FMT_YUYV or V4L2_PIX_FMT_UYVY for the CSI output format. Signed-off-by: Robby Cai <R63905@freescale.com>
