2011-10-21iommu/core: Convert iommu_found to iommu_presentJoerg Roedel1-3/+6
With per-bus iommu_ops the iommu_found function needs to work on a bus_type too. This patch adds a bus_type parameter to that function and converts all call-places. The function is also renamed to iommu_present because the function now checks if an iommu is present for a given bus and does not check for a global iommu anymore. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-10-21iommu/core: Add bus_type parameter to iommu_domain_allocJoerg Roedel2-2/+14
This is necessary to store a pointer to the bus-specific iommu_ops in the iommu-domain structure. It will be used later to call into bus-specific iommu-ops. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-10-21Driver core: Add iommu_ops to bus_typeJoerg Roedel1-0/+31
This is the starting point to make the iommu_ops used for the iommu-api a per-bus-type structure. It is required to easily implement bus-specific setup in the iommu-layer. The first user will be the iommu-group attribute in sysfs. Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>

2011-09-05iommu/omap-iovmm: support non page-aligned buffers in iommu_vmapLaurent Pinchart1-10/+26
omap_iovmm requires page-aligned buffers, and that sometimes causes omap3isp failures (i.e. whenever the buffer passed from userspace is not page-aligned). Remove this limitation by rounding the address of the first page entry down, and adding the offset back to the device address.

2011-08-26omap: iommu: remove unused exported APIOhad Ben-Cohen1-59/+0
Remove unused public APIs from OMAP's iommu driver. IOMMU functionality should be exposed only via the generic IOMMU API; this way drivers stay generic, and different IOMMU drivers don't need to duplicate similar functionalities. The rest of the API still exposed by OMAP's iommu will be evaluated and eventually either added to the generic IOMMU API (if relevant), or completely removed. The intention is that OMAP's iommu driver will eventually not expose any public API.

Move OMAP's iommu drivers to the dedicated iommu drivers folder. While OMAP's iovmm (virtual memory manager) driver does not strictly belong to the iommu drivers folder, move it there as well, because it's by no means OMAP-specific (in concept. technically it is still coupled with OMAP's iommu). Eventually, iovmm will be completely replaced with the generic, iommu-based, dma-mapping API.

Migrate OMAP's iommu driver to the generic IOMMU API, so users can stay generic, and any generic IOMMU functionality can be developed once in the generic framework. Migrate omap's iovmm (virtual memory manager) to the generic IOMMU API, and adapt omap3isp as needed, so the latter won't break. The plan is to eventually remove iovmm completely by replacing it with the (upcoming) IOMMU-based DMA-API. Tested on OMAP3 (with omap3isp) and OMAP4 (with rpmsg/remoteproc).

2011-08-26drivers/rtc/rtc-s3c.c: allow multiple open / allow no-ioctl-open'ed rtc to ↵MyungJoo Ham1-42/+25
have irq. The previous rtc-s3c had two issues related with its IRQ. 1. Users cannot open rtc multiple times because an open operation calls request_irq on the same IRQ. (e.g., two user processes wants to open and read RTC time from rtc-s3c at the same time) 2. If alarm is set and no one has the rtc opened with filesystem (either the alarm is set by kernel/boot-loader or user set an alarm and closed rtc dev file), the pending bit is not cleared and no further interrupt is invoked. When the alarm is used by the system itself such as a resume from suspend-to-RAM or other Low-power modes/idle, this is a critical issue. This patch mitigates these issues by calling request_irq at probe and free_irq at remove.

Replace/remove use of RIO v.1.2 registers/bits that are not forward-compatible with newer versions of RapidIO specification. RapidIO specification v.1.3 removed Write Port CSR, Doorbell CSR, Mailbox CSR and Mailbox and Doorbell bits of the PEF CAR. Use of removed (since RIO v.1.3) register bits affects users of currently available 1.3 and 2.x compliant devices who may use not so recent kernel versions. Removing checks for unsupported bits makes corresponding routines compatible with all versions of RapidIO specification. Therefore, backporting makes stable kernel versions compliant with RIO v.1.3 and later as well.

Calao use on there dev kits a FT2232 where the port 0 is used for the JTAG and port 1 for the UART They use the same VID and PID as FTDI Chip but they program the manufacturer name in the eeprom So use this information to detect it Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Gregory Hermant <gregory.hermant@calao-systems.com> Cc: Alan Cox <alan@linux.intel.com> Cc: stable <stable@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-08-25firmware loader: allow builtin firmware load even if usermodehelper is disabledLinus Torvalds1-5/+6
In commit a144c6a6c924 ("PM: Print a warning if firmware is requested when tasks are frozen") we not only printed a warning if somebody tried to load the firmware when tasks are frozen - we also failed the load. But that check was done before the check for built-in firmware, and then when we disallowed usermode helpers during bootup (commit 288d5abec831: "Boot up with usermodehelper disabled"), that actually means that built-in modules can no longer load their firmware even if the firmware is built in too. Which used to work, and some people depended on it for the R100 driver. So move the test for usermodehelper_is_disabled() down, to after checking the built-in firmware. This should fix: https://bugzilla.kernel.org/show_bug.cgi?id=40952 Reported-by: James Cloos <cloos@hjcloos.com> Bisected-by: Elimar Riesebieter <riesebie@lxtec.de> Cc: Michel Dänzer <michel@daenzer.net> Cc: Rafael Wysocki <rjw@sisk.pl> Cc: Greg Kroah-Hartman <gregkh@suse.de> Cc: Valdis Kletnieks <valdis.kletnieks@vt.edu> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-08-24sh-sci / PM: Use power.irq_safeRafael J. Wysocki1-0/+1
Since sci_port_enable() and sci_port_disable() may be run with interrupts off and they execute pm_runtime_get_sync() and pm_runtime_put_sync(), respectively, the SCI device's power.irq_safe flag has to be set to indicate that it is safe to execute runtime PM callbacks for this device with interrupts off.
