2016-09-24drm/bridge: analogix_dp: Improve panel on timeSean Paul
In order to reduce the time required to turn on the panel, this patch makes 2 assumptions: 1- In detect(): if there's a panel, we're connected. 2- In get_modes(): if there's a panel, let the panel driver decide if it should prepare/unprepare in order to get the modes. The first is straightforward, and shouldn't need further explanation. The second should eliminate the prepare/unprepare delays from get_modes() in most cases, since panels generally hardcode their modes in the driver as opposed to reading EDID. If a panel does need to read EDID, it should be responsible for ensuring it's in a state in which it can. Signed-off-by: Sean Paul <seanpaul@chromium.org>
2016-09-24drm/bridge: analogix_dp: Don't read EDID if panel presentSean Paul
If there's a panel connected to the analogix_dp bridge, rely on the panel driver for modes, rather than reading EDID *and* calling get_modes() on the panel. This allows panels with a valid EDID to read it in the panel driver (e.g. simple_panel), and panels with invalid EDID to homebrew modes in their get_modes implementation.

2016-09-24Bluetooth: BCSP fails to ACK re-transmitted frames from the peerDean Jenkins
Send an ACK frame with the current txack value in response to every received reliable frame unless a TX reliable frame is being sent. This modification allows re-transmitted frames from the remote peer to be acknowledged rather than ignored. It means that the remote peer knows which frame number to start re-transmitting from. Without this modification, the recovery time to a missing frame from the remote peer was unnecessarily being extended because the headers of the out of order reliable frames were being discarded rather than being processed. The frame headers of received frames will indicate whether the local peer's transmissions have been acknowledged by the remote peer. Therefore, the local peer may unnecessarily re-transmit despite the remote peer already indicating that the frame had been acknowledged in out of order reliable frame.

2016-09-24ACPI / watchdog: Add support for WDAT hardware watchdogMika Westerberg
Starting from Intel Skylake the iTCO watchdog timer registers were moved to reside in the same register space with SMBus host controller. Not all needed registers are available though and we need to unhide P2SB (Primary to Sideband) device briefly to be able to read status of required NO_REBOOT bit. The i2c-i801.c SMBus driver used to handle this and creation of the iTCO watchdog platform device. Windows, on the other hand, does not use the iTCO watchdog hardware directly even if it is available. Instead it relies on ACPI Watchdog Action Table (WDAT) table to describe the watchdog hardware to the OS. This table contains necessary information about the the hardware and also set of actions which are executed by a driver as needed. This patch implements a new watchdog driver that takes advantage of the ACPI WDAT table. We split the functionality into two parts: first part enumerates the WDAT table and if found, populates resources and creates platform device for the actual driver. The second part is the driver itself. The reason for the split is that this way we can make the driver itself to be a module and loaded automatically if the WDAT table is found. Otherwise the module is not loaded. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Rafael J.

2016-09-24PM / Domains: Don't measure latency of ->power_on|off() during system PMUlf Hansson
Measure latency does by itself contribute to an increased latency, thus we should avoid it when it isn't needed. Currently genpd measures latencies in the system PM phase for the ->power_on|off() callbacks, except in the syscore case when it's not allowed to use ktime_get() as timekeeping may be suspended. Since there should be plenty of occasions during runtime PM to perform these measurements, let's rely on that and drop them from system PM. This will also make it consistent for how measurements are done of the runtime PM callbacks (as those may be invoked during system PM).

2016-09-24PM / Domains: Remove redundant system PM callbacksUlf Hansson
In cases when the PM domain haven't assigned a system PM callback, the PM core fall-backs to check for the callback at the driver level instead. This makes it redundant to assign a pm_generic_* helper function to a corresponding system PM callback at a PM domain level. Therefore, let's remove these assignments in pm_genpd_init().

2016-09-24PM / Domains: Simplify detaching a device from its genpdUlf Hansson
There's no need to validate the PM domain by using genpd_lookup_dev() when removing the device via genpd's genpd_dev_pm_detach() function. That's because this function can't be called, unless there is a valid PM domain for the device. To simplify the behaviour, let's move code from pm_genpd_remove_device() into a new internal function, genpd_remove_device(), which is called from pm_genpd_remove_device() and genpd_dev_pm_detach().

parse_arg() duplicates the funcionality of kstrtoint() so use the latter function instead. There is no funcionality change except that in the case of input being too big -ERANGE will be returned instead of -EINVAL which is not bad because -ERANGE makes more sense here. The check for !count is already done by the sysfs core so no need to duplicate it again.

Otherwise, probing of these client drivers will likely be deferred due to that calls into clk API will return -EPROBE_DEFER. Deferred probing is not a problem for most subsystems, but could bring some side effect for particular subsystem, like display. On ZX296718 platform, we get Linux logo and boot log lost from display device, just because the DRM/KMS driver gets -EPROBE_DEFER from devm_clk_get() call. Let's use core_initcall (qcom and a few other clk drivers use that) for driver registration to avoid those unnecessary -EPROBE_DEFER and get rid of the side effect with ZX296718 display system.

2016-09-23cgroup: fix invalid controller enable rejections with cgroup namespaceTejun Heo
On the v2 hierarchy, "cgroup.subtree_control" rejects controller enables if the cgroup has processes in it. The enforcement of this logic assumes that the cgroup wouldn't have any css_sets associated with it if there are no tasks in the cgroup, which is no longer true since a79a908fd2b0 ("cgroup: introduce cgroup namespaces"). When a cgroup namespace is created, it pins the css_set of the creating task to use it as the root css_set of the namespace. This extra reference stays as long as the namespace is around and makes "cgroup.subtree_control" think that the namespace root cgroup is not empty even when it is and thus reject controller enables. Fix it by making cgroup_subtree_control() walk and test emptiness of each css_set instead of testing whether the list_head is empty. While at it, update the comment of cgroup_task_count() to indicate that the returned value may be higher than the number of tasks, which has always been true due to temporary references and doesn't break anything.

2016-09-23watchdog: txx9wdt: Add missing clock (un)prepare calls for CCFGeert Uytterhoeven
While the custom minimal TXx9 clock implementation doesn't need or use clock (un)prepare calls (they are dummies if !CONFIG_HAVE_CLK_PREPARE), they are mandatory when using the Common Clock Framework. Hence add them, to prepare for the advent of CCF.

This patch adds and entry to the sysfs to start firmware upload process on the specified device with the requested firmware. The uploading of the firmware needs only to happen once per firmware upgrade, as the firmware is stored in persistent storage. If the firmware upload or the firmware verification fails then we print and error message and exit.
