2012-02-13mmc: sdhci-pci: set Medfield SDIO as non-removableAdrian Hunter1-1/+1
Set Medfield SDIO as non-removable to avoid un-necessary card detect activity. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>
2012-01-11mmc: sdhci-pci: enable runtime PM for Medfield SDIOAdrian Hunter1-0/+7
Runtime PM for SDIO is no longer enabled by default (see 5c7f0e083d2d98ba14ddd10e88f001a0ead4cae4) so it must now be enabled per platform, in this case Medfield uses it. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Chris Ball <cjb@laptop.org>

2012-01-11mmc: sdhci-pci: add platform dataAdrian Hunter1-4/+28
Add a means of getting platform data for the SDHCI PCI devices. The data is stored against the slot not the device in order to support multi-slot devices. The data allows platform-specific setup (such as getting GPIO numbers from firmware or setting up wl12xx for SDIO) to be done in platform support files instead of the sdhci-pci driver.

2011-10-26mmc: sdhci-pci: add runtime pm supportAdrian Hunter1-1/+181
Ths patch allows runtime PM for sdhci-pci, runtime suspending after inactivity of 50ms and ensuring runtime resume before SDHC registers are accessed. During runtime suspend, interrupts are masked. The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.

2011-05-24mmc: sdhci: Fix read-only detection with JMicron 388 chipTakashi Iwai1-0/+5
On HP laptops with JMicron 388 chip, the write-locked SD card isn't detected correctly as read-only in many cases. This is because the PRESENT_STATE register becomes unsable just after plugging, and it returns the WRITE_PROTECT bit wrongly at the first read. This patch fixes the read-only detection by adding a new sdhci quirk indicating to check the register more intensively with a relatively long delay. The patch is tested with 2.6.39-rc4 kernel.

2011-04-27mmc: sdhci-pci: Fix error case in sdhci_pci_probe_slot()Chris Ball1-0/+1
If pci_ioremap_bar() fails during probe, we "goto release;" and free the host, but then we return 0 -- which tells sdhci_pci_probe() that the probe succeeded. Since we think the probe succeeded, when we unload sdhci we'll go to sdhci_pci_remove_slot() and it will try to dereference slot->host, which is now NULL because we freed it in the error path earlier. The patch simply sets ret appropriately, so that sdhci_pci_probe() will detect the failure immediately and bail out. Signed-off-by: Chris Ball <cjb@laptop.org> Cc: <stable@kernel.org>
2011-03-25mmc: use pci_dev->revisionSergei Shtylyov1-4/+2
The SDHCI driver uses PCI_CLASS_REVISION instead of PCI_REVISION_ID, so it was not converted by commit 44c10138fd4bbc4b6d6bff0873c24902f2a9da65 (PCI: Change all drivers to use pci_device->revision).

2011-01-08mmc: Add support for JMicron 388 SD/MMC controllerTakashi Iwai1-6/+41
JMicron 388 SD/MMC combo controller supports the 1.8V low-voltage for SD, but MMC doesn't work with the low-voltage, resulting in an error at probing. This patch adds the support for multiple voltage mask per device type, so that SD works with 1.8V while MMC forces 3.3V. Here new ocr_avail_* fields for each device are introduced, so that the actual OCR mask is switched dynamically. Also, the restriction of low-voltage in core/sd.c is removed when the bit is allowed explicitly via ocr_avail_sd mask. This patch was rewritten from scratch based on Aries' original code.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+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.
