2012-10-05[media] vpif_display: use a v4l2_subdev pointer to call a subdevHans Verkuil
This makes it easier to have outputs without subdevs. This needs more work. The way the outputs are configured should be identical to how inputs are configured.

2012-10-05[media] vpif_capture: separate subdev from inputHans Verkuil
vpif_capture relied on a 1-1 mapping of input and subdev. This is not necessarily the case. Separate the two. So there is a list of subdevs and a list of inputs. Each input refers to a subdev and has routing information. An input does not have to have a subdev. The initial input for each channel is set to the fist input. Currently missing is support for associating multiple subdevs with an input.

The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the first containing interleaved JPEG/YUYV data and the second containing meta data describing the interleaving method. The image data is transferred with MIPI-CSI "User Defined Byte-Based Data 1" type and is captured to memory by FIMC DMA engine. The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image Data" and it is captured in the MIPI-CSI slave device and copied to the bridge provided buffer. To make sure the size of allocated buffers is correct for the subdevs configuration when VIDIOC_STREAMON ioctl is invoked, an additional check is added at the video pipeline validation function. Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved from a sensor subdev.

2012-10-05[media] s5p-csis: Add support for non-image data packets captureSylwester Nawrocki
MIPI-CSI has internal memory mapped buffers for the frame embedded (non-image) data. There are two buffers, for even and odd frames which need to be saved after an interrupt is raised. The packet data buffers size is 4 KiB and there is no status register in the hardware where the actual non-image data size can be read from. Hence the driver copies whole packet data buffer into a buffer provided by the FIMC driver. This will form a separate plane in the user buffer. When FIMC DMA engine is stopped by the driver due the to user space not keeping up with buffer de-queuing the MIPI-CSIS will still run, however it must discard data which is not captured by FIMC. Which frames are actually capture by MIPI-CSIS is determined by means of the s_tx_buffer subdev callback. When it is not called after a single embedded data frame has been captured and copied and before next embedded data frame interrupt occurrs, subsequent embedded data frames will be dropped.

2012-10-05i2c-i801: Let i2c-mux-gpio find the GPIO chipJean Delvare
Now that i2c-mux-gpio is able to find the GPIO chip by itself, we can delegate this task. The great thing here is that i2c-mux-gpio can defer device probing until the gpio chip is available, so we no longer depend on the module loading order. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2012-10-05i2c-mux-gpio: Add support for dynamically allocated GPIO pinsJean Delvare
The code instantiating an i2c-mux-gpio platform device doesn't necessarily know in advance the GPIO pin numbers it wants to use. If pins are on a GPIO device which gets its base GPIO number assigned dynamically at run-time, the values can't be hard-coded. In that case, let the caller tell i2c-mux-gpio the name of the GPIO chip and the (relative) GPIO pin numbers to use. At probe time, the i2c-mux-gpio driver will look for the chip and apply the proper offset to turn relative GPIO pin numbers to absolute GPIO pin numbers. The same could be (and was so far) done on the caller's end, however doing it in i2c-mux-gpio has two benefits: * It avoids duplicating the code on every caller's side (about 30 lines of code.) * It allows for deferred probing for the muxed part of the I2C bus only. If finding the GPIO chip is the caller's responsibility, then deferred probing (if the GPIO chip isn't there yet) will not only affect the mux and the I2C bus segments behind it, but also the I2C bus trunk.

2012-10-05i2c-i801: Support SMBus multiplexing on Asus Z8 seriesJean Delvare
Add support for SMBus multiplexing on Asus Z8 motherboard series. On these boards, the memory slots are behind a GPIO-controlled I2C multiplexer. Models with 6 or 12 memory slots have 2 segments behind the multiplexer, while models with 18 memory slots have 3 such segments. On these boards, only the memory slots are behind the multiplexer, so it is possible to keep the autodetection mechanism. The code is generic enough so it could work on other boards as long as the multiplexer is controlled by GPIO pins. For other forms of multiplexing (for example using an I2C device) additional code will be needed. Thanks to Asus for providing a board to develop and test this feature, as well as all the technical information required. At the moment, the GPIO driver must be loaded before the i2c-i801 driver, but I hope to solve this soon, using deferred probing on the i2c-mux-gpio side.

Pull networking changes from David Miller: "The most important bit in here is the fix for input route caching from Eric Dumazet, it's a shame we couldn't fully analyze this in time for 3.6 as it's a 3.6 regression introduced by the routing cache removal. Anyways, will send quickly to -stable after you pull this in. Other changes of note: 1) Fix lockdep splats in team and bonding, from Eric Dumazet. 2) IPV6 adds link local route even when there is no link local address, from Nicolas Dichtel. 3) Fix ixgbe PTP implementation, from Jacob Keller. 4) Fix excessive stack usage in cxgb4 driver, from Vipul Pandya. 5) MAC length computed improperly in VLAN demux, from Antonio Quartulli." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (26 commits) ipv6: release reference of ip6_null_entry's dst entry in __ip6_del_rt Remove noisy printks from llcp_sock_connect tipc: prevent dropped connections due to rcvbuf overflow silence some noisy printks in irda team: set qdisc_tx_busylock to avoid LOCKDEP splat bonding: set qdisc_tx_busylock to avoid LOCKDEP splat sctp: check src addr when processing SACK to update transport state sctp: fix a typo in prototype of __sctp_rcv_lookup() ipv4: add a fib_type to fib_info can: mpc5xxx_can: fix section type conflict can: peak_pcmcia: fix error return code can: peak_pci: fix error return code cxgb4: Fix build error due to missing linux/vmalloc.h include. bnx2x: fix ring size for 10G functions cxgb4: Dynamically allocate memory in t4_memory_rw() and get_vpd_params() ixgbe: add support for X540-AT1 ixgbe: fix poll loop for FDIRCTRL.INIT_DONE bit ixgbe: fix PTP ethtool timestamping function ixgbe: (PTP) Fix PPS interrupt code ixgbe: Fix PTP X540 SDP alignment code for PPS signal ...

Merge misc patches from Andrew Morton: "The MM tree is rather stuck while I wait to find out what the heck is happening with sched/numa. Probably I'll need to route around all the code which was added to -next, sigh. So this is "everything else", or at least most of it - other small bits are still awaiting resolutions of various kinds." * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (180 commits) lib/decompress.c add __init to decompress_method and data kernel/resource.c: fix stack overflow in __reserve_region_with_split() omfs: convert to use beXX_add_cpu() taskstats: cgroupstats_user_cmd() may leak on error aoe: update aoe-internal version number to 50 aoe: update documentation to better reflect aoe-plus-udev usage aoe: remove unused code aoe: make dynamic block minor numbers the default aoe: update and specify AoE address guards and error messages aoe: retain static block device numbers for backwards compatibility aoe: support more AoE addresses with dynamic block device minor numbers aoe: update documentation with new URL and VM settings reference aoe: update copyright year in touched files aoe: update internal version number to 49 aoe: remove unused code and add cosmetic improvements aoe: increase net_device reference count while using it aoe: associate frames with the AoE storage target aoe: disallow unsupported AoE minor addresses aoe: do revalidation steps in order aoe: failover remote interface based on aoe_deadsecs parameter ...
