2018-05-11soc: qcom: Add APR bus driverSrinivas Kandagatla3-0/+388
This patch adds support to APR bus (Asynchronous Packet Router) driver. APR driver is made as a bus driver so that the apr devices can added removed more dynamically depending on the state of the services on the dsp. APR is used for communication between application processor and QDSP to use services on QDSP like Audio and others.

So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well.

2018-04-12drm/amd/display: Fix regamma not affecting full-intensity color valuesLeo (Sunpeng) Li1-3/+6
Hardware understands the regamma LUT as a piecewise linear function, with points spaced exponentially along the range. We previously programmed the LUT for range [2^-10, 2^0). This causes (normalized) color values of 1 (=2^0) to miss the programmed LUT, and fall onto the end region. For DCE, the end region is extrapolated using a single (base, slope) pair, using the max y-value from the last point in the curve as base. This presents a problem, since this value affects all three color channels. Scaling down the intensity of say - the blue regamma curve - will not affect it's end region. This is especially noticiable when using RedShift. It scales down the blue and green channels, but leaves full-intensity colors unshifted. Therefore, extend the range to cover [2^-10, 2^1) by programming another hardware segment, containing only one point. That way, we won't be hitting the end region. Note that things are a bit different for DCN, since the end region can be set per-channel.

2018-04-12nvme: expand nvmf_check_if_ready checksJames Smart7-66/+101
The nvmf_check_if_ready() checks that were added are very simplistic. As such, the routine allows a lot of cases to fail ios during windows of reset or re-connection. In cases where there are not multi-path options present, the error goes back to the callee - the filesystem or application. Not good. The common routine was rewritten and calling syntax slightly expanded so that per-transport is_ready routines don't need to be present. The transports now call the routine directly. The routine is now a fabrics routine rather than an inline function. The routine now looks at controller state to decide the action to take. Some states mandate io failure. Others define the condition where a command can be accepted. When the decision is unclear, a generic queue-or-reject check is made to look for failfast or multipath ios and only fails the io if it is so marked. Otherwise, the io will be queued and wait for the controller state to resolve. Admin commands issued via ioctl share a live admin queue with commands from the transport for controller init. The ioctls could be intermixed with the initialization commands. It's possible for the ioctl cmd to be issued prior to the controller being enabled. To block this, the ioctl admin commands need to be distinguished from admin commands used for controller init. Added a USERCMD nvme_req(req)->rq_flags bit to reflect this division and set it on ioctls requests. As the nvmf_check_if_ready() routine is called prior to nvme_setup_cmd(), ensure that commands allocated by the ioctl path (actually anything in core.c) preps the nvme_req(req) before starting the io. This will preserve the USERCMD flag during execution and/or retry.

Commit 42de82a8b544 previously attempted to fix this, and it did correctly pad the MN and FR fields with spaces, but the SN field still contains 0 bytes. The current code fills out the first 16 bytes with hex2bin, leaving the last 4 bytes zeroed. Rather than adding a lot of error-prone math to avoid overwriting SN twice, just set the whole thing to spaces up front (it's only 20 bytes).

2018-04-12nvme-pci: Separate IO and admin queue IRQ vectorsKeith Busch1-6/+17
The admin and first IO queues shared the first irq vector, which has an affinity mask including cpu0. If a system allows cpu0 to be offlined, the admin queue may not be usable if no other CPUs in the affinity mask are online. This is a problem since unlike IO queues, there is only one admin queue that always needs to be usable. To fix, this patch allocates one pre_vector for the admin queue that is assigned all CPUs, so will always be accessible. The IO queues are assigned the remaining managed vectors. In case a controller has only one interrupt vector available, the admin and IO queues will share the pre_vector with all CPUs assigned.
