2016-01-04leds: core: Drivers shouldn't enforce SYNC/ASYNC brightness settingJacek Anaszewski4-32/+19
This patch removes SET_BRIGHTNESS_ASYNC and SET_BRIGHTNESS_SYNC flags. led_set_brightness() now calls led_set_brightness_nosleep() instead of choosing between sync and async op basing on the flags defined by the driver. From now on, if a user wants to make sure that brightness will be set synchronously, they have to use led_set_brightness_sync() API. It is now being made publicly available since it has become apparent that it is a caller who should decide whether brightness is to be set in a synchronous or an asynchronous way.

2016-01-04leds: core: Use set_brightness_work for the blocking opJacek Anaszewski2-11/+11
This patch makes LED core capable of setting brightness for drivers that implement brightness_set_blocking op. It removes from LED class drivers responsibility for using work queues on their own. In order to achieve this set_brightness_delayed callback is being modified to directly call one of available ops for brightness setting. led_set_brightness_async() function didn't set brightness in an asynchronous way in all cases. It was mistakenly assuming that all LED subsystem drivers used work queue in their brightness_set op, whereas only half of them did that. Since it has no users now, it is being removed.

2016-01-04leds: core: Add led_set_brightness_nosleep{nopm} functionsJacek Anaszewski9-23/+55
This patch adds led_set_brightness_nosleep() and led_set_brightness_nopm() functions, that guarantee setting LED brightness in a non-blocking way. The latter is used from pm_ops context and doesn't modify the brightness cached in the struct led_classdev. Its execution always ends up with a call to brightness setting op - either directly or through a set_brightness_work, regardless of LED_SUSPENDED flag state. The patch also replaces led_set_brightness_async() with led_set_brightness_nosleep() in all places where the most vital was setting brightness in a non sleeping way but not necessarily asynchronously, which is not needed for non-blocking drivers.

2016-01-04leds: Rename brightness_set_sync op to brightness_set_blockingJacek Anaszewski5-5/+5
The initial purpose of brightness_set_sync op, introduced along with the LED flash class extension, was to add a means for setting torch LED brightness as soon as possible, which couldn't have been guaranteed by brightness_set op. This patch renames the op to brightness_set_blocking, which describes its purpose in a more generic way. It is beneficial in view of the prospective changes in the LED core, aiming at removing the need for using work queues in LED class drivers that can sleep or use delays while setting brightness.

2016-01-04leds: core: Add two new LED_BLINK_ flagsJacek Anaszewski1-10/+26
This patch adds LED_BLINK_BRIGHTNESS_CHANGE flag to indicate that blink brightness has changed, and LED_BLINK_DISABLE flag to indicate that blinking deactivation has been requested. In order to use the flags led_timer_function and set_brightness_delayed callbacks as well as led_set_brightness() function are being modified. The main goal of these modifications is to prepare set_brightness_work for extension of the scope of its responsibilities.

The total delay of HDMI hotplug detecting with 30ms is sometimes not enoughtfor HDMI live status up with specific HDMI monitors in BSW platform. After doing experiments for following monitors, it needs 80ms at least for those worst cases. Lenovo L246 1xwA (4 failed, necessary hot-plug delay: 58/40/60/40ms) Philips HH2AP (9 failed, necessary hot-plug delay: 80/50/50/60/46/40/58/58/39ms) BENQ ET-0035-N (6 failed, necessary hot-plug delay: 60/50/50/80/80/40ms) DELL U2713HM (2 failed, necessary hot-plug delay: 58/59ms) HP HP-LP2475w (5 failed, necessary hot-plug delay: 70/50/40/60/40ms) It looks like 70-80 ms is BSW platform needs in some bad cases of the monitors at this end (8 times delay at most). Keep less than 100ms for HDCP pulse HPD low (with at least 100ms) to respond a plug out.

2015-12-28RDMA/be2net: Remove open and close entry pointsDevesh Sharma4-45/+1
Recently Dough Ledford reported a deadlock happening between ocrdma-load sequence and NetworkManager service issueing "open" on be2net interface. The deadlock happens when any be2net hook (e.g. open/close) is called in parallel to insmod ocrdma.ko. A. be2net is sending administrative open/close event to ocrdma holding device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net. So sequence of locks is rtnl_lock---> device_list lock B. When new ocrdma roce device gets registered, infiniband stack now takes rtnl_lock in ib_register_device() in GID initialization routines. So sequence of locks in this path is device_list lock ---> rtnl_lock. This improper locking sequence causes deadlock. In order to resolve the above deadlock condition, ocrdma intorduced a patch to stop listening to administrative open/close events generated from be2net driver. It now depends on link-state-change async-event generated from CNA. This change leaves behind dead code which used to generate administrative open/close events. This patch cleans-up all that dead code from be2net.

With this patch we stop using administrative open and close events injected by be2net driver. These events were used to dispatch PORT_ACTIVE and PORT_ERROR events to the IB-stack. This patch implements a logic to receive async-link-events generated from CNA whenever link-state-change is detected. Now on, these async-events will be used to dispatch PORT_ACTIVE and PORT_ERROR events to IB-stack. Depending on async-events from CNA removes the need to hold device-list-mutex and thus breaks the busy-wait scenario.

2015-12-28RDMA/ocrdma: Fix vlan-id assignment in qp parametersDevesh Sharma1-3/+4
vlan-id is wrongly getting as 0 when PFC is enabled. Set vlan-id configured by user in QP parameters. In case vlan interface is not used, flash a warning to user to configure vlan and assign vlan-id as 0 in qp params.
