2014-09-23mei: extract supported features from the hbm versionTomas Winkler3-6/+29
extract supported hbm features and commands from the hbm version Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23mei: simplify handling of hbm client eventsTomas Winkler1-31/+43
Add mei_hbm_cl_find_by_cmd handler to retrieve the destination client Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23mei: wait for hbm start non-interruptibleAlexander Usyskin4-14/+22
We cannot handle user interrupt in context of hbm start so we only wait for time out which is reasonably short. 1. Add kdoc 2. Rename state to better reflect its function 3. Simplify wait condition and rename wait_recvd_msg to wait_hbm_start Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23mei: revamp connect and disconnect response handlingTomas Winkler2-57/+65
Both responses have same flow only the client status update is different. We introduce handler mei_hbm_cl_res() that handles both responses Also we use per client wait queue (cl->wait) rather then global dev->wait_recvd_msg Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

HBM uses global list of status values from which the values of particular commands are derived Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23mei: add mei_me_cl_by_uuid_id functionTomas Winkler8-9/+26
When handling dynamic clients there might be a race scenario in which two me clients with the same me address would be linked in the me clients list, therefore we need to search by both uuid and me address.

2014-09-23mei: use list for me clients book keepingTomas Winkler5-103/+71
To support dynamic addition/remove of clients it is more convenient to use list instead of static array Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23mei: me_client lookup function to return me_client objectTomas Winkler8-89/+74
For support of dynamic addition and removal of me clients it is more convenient to use a list instead of static array as is use now. As the first step of the transition to the new data structure we change the lookup function so it returns me client address instead of an index.

2014-09-08ARM: at91/tclib: mask interruptions at shutdown and probeGaël PORTAY1-0/+16
Shutdown properly the timer counter block by masking interruptions. Otherwise, a segmentation may happen when kexec-ing a new kernel (see backtrace below). An interruption may happen before the handler is set, leading to a kernel segmentation fault. Furthermore, we make sure the interruptions are masked when the driver is initialized. This will prevent freshly kexec-ed kernel from crashing when launched from a kernel which does not properly mask interruptions at shutdown. The backtrace below happened after kexec-ing a new kernel, from a kernel that did not shut down properly leaving interruptions unmasked.

2014-09-08ARM: at91/tclib: move initialization from alloc to probeGaël PORTAY1-49/+22
Move resource retrieval from atmel_tc_alloc to tc_probe to avoid lately reporting resource related issues when a TC block user request a TC block. Moreover, resources retrieval are usually done in the probe function, thus moving them add some consistency with other drivers. Initialization is done once, ie not every time a tc block is requested. If it fails, the device is not appended to the list of tc blocks. Furhermore, the device id is retrieved at probe as well, avoiding parsing DT every time the user requests of tc block.

Both of these have lacked active support for quite a while, and after asking around nobody showed interest in keeping them around. If needed, they could be resurrected in the future but it's more likely that we would prefer reintroduction of them as DT and multiplatform-enabled platforms instead. - OMAP4 controller code register define diet. They defined a lot of registers that were never actually used, etc. - Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate) to drivers/soc so it can be shared with 64-bit code. This also converts them over to traditional driver models where possible. - Removal of legacy gpio-samsung driver, since the last users have been removed (moved to pinctrl) Plus a bunch of smaller changes for various platforms that sort of dissapear in the diffstat for the above. clps711x cleanups, shmobile header file refactoring/moves for multiplatform friendliness, some misc cleanups, etc" * tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (117 commits) drivers: CCI: Correct use of ! and & video: clcd-versatile: Depend on ARM video: fix up versatile CLCD helper move MAINTAINERS: Add sdhci-st file to ARCH/STI architecture ARM: EXYNOS: Fix build breakge with PM_SLEEP=n MAINTAINERS: Remove Kirkwood ARM: tegra: Convert PMC to a driver soc/tegra: fuse: Set up in early initcall ARM: tegra: Always lock the CPU reset vector ARM: tegra: Setup CPU hotplug in a pure initcall soc/tegra: Implement runtime check for Tegra SoCs soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra ...

Pull timer and time updates from Thomas Gleixner: "A rather large update of timers, timekeeping & co - Core timekeeping code is year-2038 safe now for 32bit machines. Now we just need to fix all in kernel users and the gazillion of user space interfaces which rely on timespec/timeval :) - Better cache layout for the timekeeping internal data structures. - Proper nanosecond based interfaces for in kernel users. - Tree wide cleanup of code which wants nanoseconds but does hoops and loops to convert back and forth from timespecs. Some of it definitely belongs into the ugly code museum. - Consolidation of the timekeeping interface zoo. - A fast NMI safe accessor to clock monotonic for tracing. This is a long standing request to support correlated user/kernel space traces. With proper NTP frequency correction it's also suitable for correlation of traces accross separate machines. - Checkpoint/restart support for timerfd. - A few NOHZ[_FULL] improvements in the [hr]timer code. - Code move from kernel to kernel/time of all time* related code. - New clocksource/event drivers from the ARM universe. I'm really impressed that despite an architected timer in the newer chips SoC manufacturers insist on inventing new and differently broken SoC specific timers. [ Ed. "Impressed"? I don't think that word means what you think it means ] - Another round of code move from arch to drivers.

2014-07-19Merge tag 'tegra-for-3.17-fuse-move' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/cleanupOlof Johansson1-0/+1
Merge "ARM: tegra: move fuse code out of arch/arm" from Thierry Reding: This branch moves code related to the Tegra fuses out of arch/arm and into a centralized location which could be shared with ARM64. It also adds support for reading the fuse data through sysfs. Included is also some preparatory work that moves Tegra-related header files from include/linux to include/soc/tegra as suggested by Arnd. Furthermore the Tegra chip ID is now retrieved using a function rather than a variable so that sanity checks can be done. This is convenient in subsequent patches that will move some of the code that's currently called from Tegra machine setup into regular initcalls so that it can be reused on 64-bit ARM. The sanity checks help with verifying that no code tries to obtain the Tegra chip ID before the underlying driver is properly initialized. * tag 'tegra-for-3.17-fuse-move' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: soc/tegra: fuse: fix dummy functions soc/tegra: fuse: move APB DMA into Tegra20 fuse driver soc/tegra: Add efuse and apbmisc bindings soc/tegra: Add efuse driver for Tegra ARM: tegra: move fuse exports to soc/tegra/fuse.h ARM: tegra: export apb dma readl/writel ARM: tegra: Use a function to get the chip ID ARM: tegra: Sort includes alphabetically ARM: tegra: Move includes to include/soc/tegra Signed-off-by: Olof Johansson <olof@lixom.net>

2014-07-17mei: don't schedule suspend in pm idleAlexander Usyskin2-2/+2
Calling pm_schedule_suspend from the runtime pm idle callback may reschedule existing timer, thus in case of frequent runtime rpm idle call the suspend maybe starved. Instead we call pm_runtime_autosuspend which is checking if the timer is already charged. An example is monitoring device pci config space. Pci config sysfs handlers calls pci_config_pm_runtime_put/get helpers which in turns calls to device idle callback Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Alexander Usyskin <alexander.usyskin@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

The MIC bus hardware operations provide a way to abstract certain hardware details from the base physical devices. Examples of devices added on the MIC virtual bus include host DMA and card DMA.
