2012-07-24i2c-tiny-usb: Add support for the Robofuzz OSIF USB/I2C converterEmmanuel Deloget
Robofuzz OSIF is a generic USB/iIC interface that embeds an ATMega8A AVR-RISC microcontroler. The device is based upon Till Harbaum's i2c-tiny-usb and although it enhances the original design with further functionnalities it still maintain compatibility with it with respect to the USB/I2C interface.

2012-07-24i2c-i801: Enable IRQ for byte_by_byte transactionsDaniel Kurtz
Byte-by-byte transactions are used primarily for accessing I2C devices with an SMBus controller. For these transactions, for each byte that is read or written, the SMBus controller generates a BYTE_DONE IRQ. The isr reads/writes the next byte, and clears the IRQ flag to start the next byte. On the penultimate IRQ, the isr also sets the LAST_BYTE flag. There is no locking around the cmd/len/count/data variables, since the I2C adapter lock ensures there is never multiple simultaneous transactions for the same device, and the driver thread never accesses these variables while interrupts might be occurring. The end result is faster I2C block read and write transactions. Note: This patch has only been tested and verified by doing I2C read and write block transfers on Cougar Point 6 Series PCH, as well as I2C read block transfers on ICH5.

2012-07-24i2c-i801: Enable interrupts on ICH5/7/8/9/10Jean Delvare
Enable interrupts on more devices. ICH5, ICH7(-M) and ICH10 have been tested to work OK. ICH8 and ICH9 are expected to work just fine as they are very close to ICH7 and ICH10. Ultimately we want to enable this feature on at least every device since the ICH5, but for now we limit the exposure. We'll enable it for other devices if we don't get negative feedback. As a bonus, let the user know when interrupts are used. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Daniel Kurtz <djkurtz@chromium.org>
2012-07-24i2c-i801: Enable IRQ for SMBus transactionsDaniel Kurtz
Add a new 'feature' to i2c-i801 to enable using PCI interrupts. When the feature is enabled, then an isr is installed for the device's PCI IRQ. An I2C/SMBus transaction is always terminated by one of the following interrupt sources: FAILED, BUS_ERR, DEV_ERR, or on success: INTR. When the isr fires for one of these cases, it sets the ->status variable and wakes up the waitq. The waitq then saves off the status code, and clears ->status (in preparation for some future transaction). The SMBus controller generates an INTR irq at the end of each transaction where INTREN was set in the HST_CNT register. No locking is needed around accesses to priv->status since all writes to it are serialized: it is only ever set once in the isr at the end of a transaction, and cleared while no interrupts can occur. In addition, the I2C adapter lock guarantees that entire I2C transactions for a single adapter are always serialized. For this patch, the INTREN bit is set only for SMBus block, byte and word transactions, but not for I2C reads or writes. The use of the DS (BYTE_DONE) interrupt with byte-by-byte I2C transactions is implemented in a subsequent patch. The interrupt feature has only been enabled for COUGARPOINT hardware. In addition, it is disabled if SMBus is using the SMI# interrupt. Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2012-07-24i2c-i801: Consolidate pollingJean Delvare
(Based on earlier work by Daniel Kurtz.) Come up with a consistent, driver-wide strategy for event polling. For intermediate steps of byte-by-byte block transactions, check for BYTE_DONE or any error flag being set. At the end of every transaction (regardless of PEC being used), check for both BUSY being cleared and INTR or any error flag being set. This ensures proper action for all transaction types.

2012-07-24i2c-i801: Check and return errors during byte-by-byte transfersDaniel Kurtz
If an error is detected in the polling loop, abort the transaction and return an error code. * DEV_ERR is set if the device does not respond with an acknowledge, and the SMBus controller times out (minimum 25ms). * BUS_ERR is set if a bus arbitration collision is detected. In other words, when the SMBus controller tries to generate a START condition, but detects that the SMBDATA is being held low, usually by another SMBus/I2C master. * FAILED is only set if a transaction is stopped by software (using the SMBHSTCNT KILL bit).

2012-07-24i2c-i801: Clear only status bits in HST_STSDaniel Kurtz
Writing back the whole status register could clear unwanted bits. In particular, it could clear the "INUSE_STS" bit, which is a 'hardware semaphore', that might be useful to use some day. To prepare for this, let's ban writing back the whole status to register HST_STS, of which this is the only instance.

As a slight optimization, pull some logic out of the polling loop during byte-by-byte transactions by just setting the I801_LAST_BYTE bit, as defined in the i801 (PCH) datasheet, when reading the last byte of a byte-by-byte I2C_SMBUS_READ.

2012-07-24i2c-piix4: Separate registration and probing codeAndrew Armenia
Some chipsets have multiple sets of SMBus registers each controlling a separate SMBus. Supporting these chipsets properly will require registering multiple I2C adapters for one piix4. The code to initialize and register the i2c_adapter structure has been separated from piix4_probe and allows registration of a piix4 adapter given its base address. Note that the i2c_adapter and i2c_piix4_adapdata structures are now dynamically allocated. Signed-off-by: Andrew Armenia <andrew@asquaredlabs.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2012-07-24i2c-piix4: Eliminate piix4_smba global variableAndrew Armenia
Some chipsets have multiple sets of piix4-compatible SMBus registers. Eliminating the global variable will allow these chipsets to be fully supported. Return value from piix4_setup and piix4_sb800_setup now returns the smba value detected. This is stored in a struct i2c_piix4_adapdata. Thus the global variable is eliminated.

Pull support for three new arm SoC types from Arnd Bergmann: - The mvebu platform includes Marvell's Armada XP and Armada 370 chips, made by the mvebu business unit inside of Marvell. Since the same group also made the older but similar platforms we call "orion5x", "kirkwood", "mv78xx0" and "dove", we plan to move all of them into the mach-mvebu directory in the future. - socfpga is Altera's platform based on Cortex-A9 cores and a lot of FPGA space. This is similar to the Xilinx zynq platform we already support. The code is particularly clean, which is helped by the fact that the hardware doesn't do much besides the parts that are expected to get added in the FPGA. - The OMAP subarchitecture gains support for the latest generation, the OMAP5 based on the new Cortex-A15 core.

Then I've decided to keep this knob because it is also useful for UBIFS power-cut recovery end error-paths testing. - Well-spotted fix from Julia.

The only checks of the long argument passed to fcntl(fd,F_SETLEASE,.) are done after converting the long to an int. Thus some illegal values may be let through and cause problems in later code. [ They actually *don't* cause problems in mainline, as of Dave Jones's commit 8d657eb3b438 "Remove easily user-triggerable BUG from generic_setlease", but we should fix this anyway. And this patch will be necessary to fix real bugs on earlier kernels. ] Cc: stable@vger.kernel.org Signed-off-by: J.

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull the big VFS changes from Al Viro: "This one is *big* and changes quite a few things around VFS. What's in there: - the first of two really major architecture changes - death to open intents. The former is finally there; it was very long in making, but with Miklos getting through really hard and messy final push in fs/namei.c, we finally have it. Unlike his variant, this one doesn't introduce struct opendata; what we have instead is ->atomic_open() taking preallocated struct file * and passing everything via its fields. Instead of returning struct file *, it returns -E... on error, 0 on success and 1 in "deal with it yourself" case (e.g. symlink found on server, etc.). See comments before fs/namei.c:atomic_open(). That made a lot of goodies finally possible and quite a few are in that pile: ->lookup(), ->d_revalidate() and ->create() do not get struct nameidata * anymore; ->lookup() and ->d_revalidate() get lookup flags instead, ->create() gets "do we want it exclusive" flag. With the introduction of new helper (kern_path_locked()) we are rid of all struct nameidata instances outside of fs/namei.c; it's still visible in namei.h, but not for long. Come the next cycle, declaration will move either to fs/internal.h or to fs/namei.c itself. [me, miklos, hch] - The second major change: behaviour of final fput(). Now we have __fput() done without any locks held by caller *and* not from deep in call stack. That obviously lifts a lot of constraints on the locking in there. Moreover, it's legal now to call fput() from atomic contexts (which has immediately simplified life for aio.c). We also don't need anti-recursion logics in __scm_destroy() anymore. There is a price, though - the damn thing has become partially asynchronous. For fput() from normal process we are guaranteed that pending __fput() will be done before the caller returns to userland, exits or gets stopped for ptrace. For kernel threads and atomic contexts it's done via schedule_work(), so theoretically we might need a way to make sure it's finished; so far only one such place had been found, but there might be more. There's flush_delayed_fput() (do all pending __fput()) and there's __fput_sync() (fput() analog doing __fput() immediately). I hope we won't need them often; see warnings in fs/file_table.c for details. [me, based on task_work series from Oleg merged last cycle] - sync series from Jan - large part of "death to sync_supers()" work from Artem; the only bits missing here are exofs and ext4 ones. As far as I understand, those are going via the exofs and ext4 trees resp.; once they are in, we can put ->write_super() to the rest, along with the thread calling it. - preparatory bits from unionmount series (from dhowells). - assorted cleanups and fixes all over the place, as usual. This is not the last pile for this cycle; there's at least jlayton's ESTALE work and fsfreeze series (the latter - in dire need of fixes, so I'm not sure it'll make the cut this cycle). I'll probably throw symlink/hardlink restrictions stuff from Kees into the next pile, too.

2012-07-23powerpc/mpic: Create a revmap with enough entries for IPIs and timersBenjamin Herrenschmidt
The current mpic code creates a linear revmap just big enough for all the sources, which happens to miss the IPIs and timers on some machines. This will in turn break when the irqdomain code loses the fallback of doing a linear search when the revmap fails (and really slows down IPIs otherwise).

2012-07-22mmc: omap_hsmmc: ensure probe returns error upon resource failureKevin Hilman
If platform_get_resource_by_name() fails, driver probe is aborted an should return an error so the driver is not bound to the device. However, in the current error path of platform_get_resource_by_name(), probe returns zero since the return value (ret) is not properly set. With a zero return value, the driver core assumes probe was successful and will bind the driver to the device. Fix this by ensuring that probe returns an error code in this failure path.
