2015-06-11drm/msm: workaround for missing irq on a306/8x16Rob Clark

2015-06-11drm/msm: adreno a306 supportRob Clark
As found in apq8016 (used in DragonBoard 410c) and msm8916. Note that numerically a306 is actually 307 (since a305c already claimed 306). Nice and confusing. Signed-off-by: Rob Clark <robdclark@gmail.com>
2015-06-11drm/msm: clarify downstream bus scalingRob Clark
A few spots in the driver have support for downstream android CONFIG_MSM_BUS_SCALING. This is mainly to simplify backporting the driver for various devices which do not have sufficient upstream kernel support. But the intentionally dead code seems to cause some confusion. Rename the #define to make this more clear. Signed-off-by: Rob Clark <robdclark@gmail.com>

2015-06-11drm/msm/adreno: dump scratch regs and other info on hangRob Clark
Dump a bit more info when the GPU hangs, without having hang_debug enabled (which dumps a *lot* of registers). Also dump the scratch registers, as they are useful for determining where in the cmdstream the GPU hung (and they seem always safe to read when GPU has hung). Note that the freedreno gallium driver emits increasing counter values to SCRATCH6 (to identify tile #) and SCRATCH7 (to identify draw #), so these two in particular can be used to "triangulate" where in the cmdstream the GPU hung.

2015-06-11mailbox: Add ability for clients to request channels by nameLee Jones
This patch supplies a new framework API; mbox_request_channel_byname(). It works by supplying the usual client pointer as the first argument and a string as the second. The API will search the client's node for a 'mbox-names' property then request a channel in the normal way using the requested string's index as the expected second 'index' argument.

2015-06-11mailbox: Enable BCM2835 mailbox supportLubomir Rintel
This mailbox driver provides a single mailbox channel to write 32-bit values to the VPU and get a 32-bit response. The Raspberry Pi firmware uses this mailbox channel to implement firmware calls, while Roku 2 (despite being derived from the same firmware tree) doesn't. The driver was originally submitted by Lubomir, based on the out-of-tree 2708 mailbox driver. Eric Anholt fixed it up for upstreaming, with the major functional change being that it now has no notion of multiple channels (since that is a firmware-dependent concept) and instead the raspberrypi-firmware driver will do that bit-twiddling in its own messages.

2015-06-11staging/lustre/llite: fix ll_getname user buffer copyOleg Drokin
strncpy_from_user could return negative values on error, so need to take those into account. Since ll_getname is used to get a single component name from userspace to transfer to server as-is, there's no need to allocate 4k buffer as done by __getname. Allocate NAME_MAX+1 buffer instead to ensure we have enough for a null terminated max valid length buffer.

2015-06-11ntb: initialize max_mw for Atom before using itDaniel Verkamp
Commit ab760a0 (ntb: Adding split BAR support for Haswell platforms) changed ntb_device's mw from a fixed-size array into a pointer that is allocated based on limits.max_mw; however, on Atom platforms, max_mw is not initialized until ntb_device_setup(), which happens after the allocation. Fill out max_mw in ntb_atom_detect() to match ntb_xeon_detect(); this happens before the use of max_mw in the ndev->mw allocation.

2015-06-11gpio / ACPI: Return -EPROBE_DEFER if the gpiochip was not foundMika Westerberg
If a driver requests a GPIO described in its _CRS but the GPIO host controller (gpiochip) driver providing the GPIO has not been loaded yet acpi_get_gpiod() returns -ENODEV which causes the calling driver to fail. If the gpiochip driver is loaded afterwards the driver requesting the GPIO will not notice this. Better approach is to return -EPROBE_DEFER in such case. Then when the gpiochip driver appears the driver requesting the GPIO will be probed again. This also aligns ACPI GPIO lookup code closer to DT as it does pretty much the same when no gpiochip driver was found.
