* memstick: rtsx_usb_ms: Manage runtime PM when accessing the deviceUlf Hansson2016-10-171-0/+4
| | | | | | | | | | | | | | | Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed. This is currently not the case and it could trigger various errors. Fix this by properly deal with runtime PM in this regards. This means making sure the device is runtime resumed, when serving requests via the ->request() callback or changing settings via the ->set_param() callbacks.

* memstick: rtsx_usb_ms: Runtime resume the device when polling for cardsAlan Stern2016-10-171-0/+2
| | | | | | | | | | | | | | | Accesses to the rtsx usb device, which is the parent of the rtsx memstick device, must not be done unless it's runtime resumed. Therefore when the rtsx_usb_ms driver polls for inserted memstick cards, let's add pm_runtime_get|put*() to make sure accesses is done when the rtsx usb device is runtime resumed.

* rtsx_usb_ms: use schedule_timeout_idle() in polling loopOleksandr Natalenko2016-05-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | First version of this patch has already been posted to LKML by Ben Hutchings ~6 months ago, but no further action were performed. Ben's original message: : rtsx_usb_ms creates a task that mostly sleeps, but tasks in : uninterruptible sleep still contribute to the load average (for : bug-compatibility with Unix). A load average of ~1 on a system that : should be idle is somewhat alarming. : : Change the sleep to be interruptible, but still ignore signals.

* drivers/memstick/host/r592.c: avoid gcc-6 warningArnd Bergmann2016-03-261-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The r592 driver relies on behavior of the DMA mapping API that is normally observed but not guaranteed by the API. Instead it uses a runtime check to fail transfers if the API ever behaves When CONFIG_NEED_SG_DMA_LENGTH is not set, one of the checks turns into a comparison of a variable with itself, which gcc-6.0 now warns about: drivers/memstick/host/r592.c: In function 'r592_transfer_fifo_dma': drivers/memstick/host/r592.c:302:31: error: self-comparison always evaluates to false [-Werror=tautological-compare] (sg_dma_len(&dev->req->sg) < dev->req->sg.length)) { ^ The check itself is not a problem, so this patch just rephrases the condition in a way that gcc does not consider an indication of a mistake. We already know that dev->req->sg.length was initially R592_LFIFO_SIZE, so we can compare it to that constant again.

| | | | | | | | | | | | | | | | | | This patch is used to add support for ms card. The main difference between ms card and mspro card is long data transfer mode. mspro card can use auto mode DMA for long data transfer, but ms can not use this mode, it should use normal mode DMA. The memstick core added support for ms card, but the original driver will make ms card fail at initialization, because it uses auto mode DMA. This patch makes the ms card work properly.

| * mfd: rtsx: Fix issue that booting OS with SD card insertedWei WANG2013-02-141-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek card reader supports both SD and MS card. According to the settings of rtsx MFD driver, SD host will be probed before MS host. If we boot/reboot Linux with SD card inserted, the resetting flow of SD card will succeed, and the following resetting flow of MS is sure to fail. Then MS upper-level driver will ask rtsx driver to turn power off. This request leads to the result that the following SD commands fail and SD card can't be accessed again. In this commit, Realtek's SD and MS host driver will check whether the card that upper driver requesting is the one existing in the slot. If not, Realtek's host driver will refuse the operation to make sure the exlusive accessing at the same time.

* 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.

The only adapter I have which supports the 8b mode (the Jmicron) had some problems with its clock wiring and they discovered it only now. We also discovered that ProHG media is more sensitive to the ordering of initialization commands. - Make the driver fall back to highest supported mode instead of always falling back to serial. The driver will attempt the switch to 8b mode for any new MSPro card, but not all of them support it. Previously, these new cards ended up in serial mode, which is not the best idea (they work fine with 4b, after all). - Edit some macros for better conformance to Sony documentation Signed-off-by: Alex Dubov <oakad@yahoo.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* memstick: allow "set_param" method to return an error codeAlex Dubov2008-07-262-27/+57
| | | | | | | | | | | | | Some controllers (Jmicron, for instance) can report temporal failure condition during power-on. It is desirable to account for this using a return value of "set_param" device method. The return value can also be handy to distinguish between supported and unsupported device parameters in run time.

| | | | | | | | | | | MemoryStick storage cards, when in parallel mode, send several meaningful bits of their "INT" register as part of command response. This data is stored by host and can be used to spare invocation of "GET_INT" TPC on each data page transferred between host and card.
