2017-08-27remoteproc/keystone: explicitly request exclusive reset controlPhilipp Zabel1-1/+1
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

2017-08-24remoteproc/keystone: Add support for Keystone 66AK2G SOCsSuman Anna1-0/+1
Add support to the keystone remoteproc driver for managing the DSP present in the Keystone 2 66AK2G SoC. The 66AK2G SoC has a Power Management Micro Controller (PMMC) that manages the individual device's power, clock and reset functionalities. The keystone remoteproc driver already uses standard frameworks for reset and clock control, so it doesn't require any significant modifications other than a new compatible suitable for 66AK2G DSP. The binding document is also updated to reflect the modified property values used by the 66AK2G DSP node as compared to the values used by existing Keystone 2 DSPs.

2017-08-24remoteproc/davinci: Add device tree support for OMAP-L138 DSPSuman Anna1-3/+27
The Davinci remoteproc driver currently supports the DSP remoteproc device created in legacy-style on OMAP-L13x SoCs. The driver has been enhanced to support the DSP remoteproc device created through Device Tree now. The current DT support handles the C674x DSP processor subsystem on OMAP-L138 SoCs.

2017-08-24remoteproc/davinci: Add support to parse internal memoriesSuman Anna1-0/+62
The DSP subsystem on OMAP-L13x SoCs has various internal RAM memories that can accessed from the ARM side. These memories can be configured to be used as either RAM or Cache. The Davinci remoteproc driver has been enhanced to parse and store the kernel mappings for these internal RAM memories. These mappings can then be used to support direct loading of text/data into these memories from the remoteproc driver.

2017-08-24remoteproc/davinci: Switch to platform_get_resource_byname()Suman Anna1-2/+4
The davinci remoteproc driver currently uses the platform_get_resource() API for retrieving the IOMEM resources. Switch this function to use the platform_get_resource_byname() API instead in preparation for adding the DT support so that the binding can be agnostic of the IOMEM resource order.

2017-08-02soc: qcom: GLINK SSR notifierBjorn Andersson3-0/+174
This driver register as a subsystem restart notifier and will send out notifications to remote processors that has opened the "glink_ssr" GLINK channel. This mechanism is used to signal any GLINK participants that a 3rd party is gone and that the communication state has to be reset; i.e. that read and write pointers of the GLINK FIFOs are stale.

2017-08-02remoteproc: qcom: Add support for SSR notificationsBjorn Andersson4-0/+90
This adds the remoteproc part of subsystem restart, which is responsible for emitting notifications to other processors in the system about a dying remoteproc instance. These notifications are propagated to the various communication systems in the various remote processors to shut down communication links that was left in a dangling state as the remoteproc was stopped (or crashed).

2017-07-26remoteproc: Merge __rproc_boot() with rproc_boot()Suman Anna2-12/+2
The additional arguments in the internal __rproc_boot() function were dropped in commit 2bfc311a57f5 ("remoteproc: Drop wait in __rproc_boot()"). The exported rproc_boot() is now just a wrapper around this internal function, so merge them together. While at this, also remove the declaration for the previously cleaned up rproc_boot_nowait() function.

2017-07-15random: suppress spammy warnings about unseeded randomnessTheodore Ts'o1-17/+39
Unfortunately, on some models of some architectures getting a fully seeded CRNG is extremely difficult, and so this can result in dmesg getting spammed for a surprisingly long time. This is really bad from a security perspective, and so architecture maintainers really need to do what they can to get the CRNG seeded sooner after the system is booted. However, users can't do anything actionble to address this, and spamming the kernel messages log will only just annoy people. For developers who want to work on improving this situation, CONFIG_WARN_UNSEEDED_RANDOM has been renamed to CONFIG_WARN_ALL_UNSEEDED_RANDOM. By default the kernel will always print the first use of unseeded randomness. This way, hopefully the security obsessed will be happy that there is _some_ indication when the kernel boots there may be a potential issue with that architecture or subarchitecture. To see all uses of unseeded randomness, developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM. Signed-off-by: Theodore Ts'o <tytso@mit.edu>

2017-07-13PCI / PM: Fix native PME handling during system suspend/resumeRafael J. Wysocki1-22/+13
Commit 76cde7e49590 (PCI / PM: Make PCIe PME interrupts wake up from suspend-to-idle) went too far with preventing pcie_pme_work_fn() from clearing the root port's PME Status and re-enabling the PME interrupt which should be done for PMEs to work correctly after system resume. The failing scenario is as follows: 1. pcie_pme_suspend() finds that the PME IRQ should be designated for system wakeup, so it calls enable_irq_wake() and then sets data->suspend_level to PME_SUSPEND_WAKEUP. 2. PME interrupt happens at this point. 3. pcie_pme_irq() runs, disables the PME interrupt and queues up the execution of pcie_pme_work_fn(). 4. pcie_pme_work_fn() runs before pcie_pme_resume() and breaks out of the loop right away, because data->suspend_level is not PME_SUSPEND_NONE, and it doesn't re-enable the PME interrupt for the same reason. 5. pcie_pme_resume() runs and simply calls disable_irq_wake() without re-enabling the PME interrupt (because data->suspend_level is not PME_SUSPEND_NONE), so the PME interrupt remains disabled and the PME Status remains set. To fix this notice that there is no reason why pcie_pme_work_fn() should behave in a special way during system resume if the PME interrupt is not disabled by pcie_pme_suspend() and partially revert commit 76cde7e49590 and restore the previous (and correct) behavior of pcie_pme_work_fn().

2017-07-12video: fbdev: intelfb: move inline before return typeJoe Perches1-1/+1
Make the code like the rest of the kernel. But there is an oddity here because the inline should probably be removed. It's an extern function in intelfb.h and it is used in intelfbdrv.c and intelfbhw.c. The inline is kept here as I suppose it's possible for some compiler to make the uses inline in intelfbdrv and and also create an external function for intelfbhw.
