| | | | | | | | | | | Since commit 3c47d19ff4dc ("drivers: base: add coredump driver ops") it is possible to initiate a device coredump from user-space. This patch adds support for it in btmrvl_sdio adding the .coredump() driver callback. This makes dump through debugfs obsolete so removing it.

* btmrvl: add platform specific wakeup interrupt supportXinming Hu2016-05-021-0/+11
| | | | | | | | | | | | | On some arm-based platforms, we need to configure platform specific parameters by device tree node and also define our node as a child node of parent SDIO host controller. This patch parses these parameters from device tree. It includes calibration data download to firmware, wakeup pin configured to firmware, and soc specific wake up gpio, which will be set as wakeup interrupt pin.

* Bluetooth: btmrvl: don't send data to firmware while processing suspendChin-Ran Lo2016-01-061-0/+1
| | | | | | | | | | | | | | | | | | | | Usually when driver sends data to firmware it receives TX_DONE (DN_LD_HOST_INT_STATUS) interrupt from firmware right away. It's also observed that some times the fireware could delay sending DN_LD_HOST_INT_STATUS interrupt. If driver sends data to firmware during suspend processing and the TX_DONE interrupt is delayed, it may come back at wrong time when SDIO host driver is in the middle of suspending. Block any data from stack while suspending. Also skip sending data that are already in driver tx_queue. Don't purge the skb queue on suspend to avoid intermittent music after system resumes from S3.

* Bluetooth: btmrvl add firmware dump supportXinming Hu2014-12-031-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds firmware dump support for marvell bluetooth chipset. Currently only SD8897 is supported. This is implemented based on dev_coredump, a new mechnism introduced in kernel 3.18rc3 Firmware dump can be trigger by echo 1 > /sys/kernel/debug/bluetooth/hci*/config/fw_dump and when the dump operation is completed, data can be read by cat /sys/class/devcoredump/devcd*/data We have prepared following script to divide fw memory dump data into multiple files based on memory type.

* Bluetooth: btmrvl: wait for HOST_SLEEP_ENABLE event in suspendChin-Ran Lo2014-07-031-0/+1
| | | | | | | | | | | | | | | | | After BT_CMD_HOST_SLEEP_ENABLE command finishes, driver should wait until getting BT_EVENT_HOST_SLEEP_ENABLE event to complete suspend procedure. Without this patch the suspend handler would return success earlier. By the time when the BT_EVENT_HOST_SLEEP_ENABLE event comes in the controller driver could have already turned off the bus clock. This causes kernel crash or system reboot eventually.

* Bluetooth: btmrvl: use cal-data from device-tree instead of conf fileBing Zhao2013-12-041-4/+0
| | | | | | | | | | | | | | | | | | | | | | | Some ARM versions of Chromebook need to download a new calibration data from host driver to firmware. They do have EEPROM but still need a piece of new calibration data in test mode. The cal-data is platform dependent. It's simpler and more feasible to use device tree based cal-data instead of configuration file based cal-data. This patch remove configuration file based cal-data downloading and replace it using cal-data from device tree. When CONFIG_OF is not selected, or the specific property is not present in the device tree, the calibration downloading will not happen.

| | | | | | | | | | | | | | | When driver is sending a command or data and the firmware is also sending a sleep event, sometimes it is observed that driver will continue to send the command/data to firmware right after processing sleep event. Once sleep event is processed driver is not supposed to send anything because firmware is in sleep state after that. Previously interrupt processing was done in SDIO interrupt callback handler. Now it is done in btmrvl driver main thread to solve the cross-sending properly.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
