* w1-gpio: handle of_get_gpio() returning -EPROBE_DEFER betterUwe Kleine-König2014-02-151-5/+14
| | | | | | | | | | | | | | | | | | of_get_gpio() might return -EPROBE_DEFER meaning that the driver providing the gpio isn't ready yet. If that happens for the first gpio the resulting kernel output without this patch is: w1-gpio somename: Failed to parse DT platform somename: Driver w1-gpio requests probe deferral The first message is misleading and so is suppressed with this patch. Further if determining the gpio to switch the external pullup yields -EPROBE_DEFER this error should be passed back to the caller instead of just continuing without pullup.

* regmap: spmi: support base and extended register spacesJosh Cartwright2014-02-151-31/+197
| | | | | | | | | | | | | | | | | SPMI states that a slave may contain two register spaces, the Base register space is a 5-bit byte-addressable space accessed via the Register Read/Write and Register Zero Write command sequences, and the Extended register space: a 16-bit byte-addressable space accessed via the Extended Read/Write and Extended Read/Write Long command sequences. Provide support for accessing both of these spaces, taking advantage of the more bandwidth-efficient commands ('Register 0 Write' vs 'Register Write', and 'Extended Register Read/Write' vs 'Extended Register Read/Write Long') when possible.

* spmi: pmic_arb: add support for interrupt handlingJosh Cartwright2014-02-152-2/+376
| | | | | | | | | | | | | | The Qualcomm PMIC Arbiter, in addition to being a basic SPMI controller, also implements interrupt handling for slave devices. Note, this is outside the scope of SPMI, as SPMI leaves interrupt handling completely unspecified. Extend the driver to provide a irq_chip implementation and chained irq handling which allows for these interrupts to be used.

* spmi: Add MSM PMIC Arbiter SPMI controllerKenneth Heitke2014-02-153-0/+424
| | | | | | | | | | | | | | | | | | | Qualcomm's PMIC Arbiter SPMI controller functions as a bus master and is used to communication with one or more PMIC (slave) devices on the SPMI bus. The PMIC Arbiter is actually a hardware wrapper around the SPMI controller that provides concurrent and autonomous PMIC access to various entities that need to communicate with the PMIC. The SPMI controller hardware handles all of the SPMI bus activity (bus arbitration, sequence start condition, transmission of frames, etc). This software driver uses the PMIC Arbiter register interface to initiate command sequences on the SPMI bus. The status register is read to determine when the command sequence has completed and whether or not it completed successfully.

* spmi: Linux driver framework for SPMIKenneth Heitke2014-02-155-0/+625
| | | | | | | | | | | | | | | | | System Power Management Interface (SPMI) is a specification developed by the MIPI (Mobile Industry Process Interface) Alliance optimized for the real time control of Power Management ICs (PMIC). SPMI is a two-wire serial interface that supports up to 4 master devices and up to 16 logical slaves. The framework supports message APIs, multiple busses (1 controller per bus) and multiple clients/slave devices per controller.

* VME: Stop using memcpy_[to|from]io() due to unwanted behaviourMartyn Welch2014-02-152-24/+23
| | | | | | | | | | | | | The ca91cx42 and tsi148 VME bridges use the width of reads and writes on the PCI bus in part to control the width of the cycles on the VME bus. It is important that we can control the width of cycles on the VME bus as some VME hardware requires cycles of a specific width. The memcpy_toio() and memcpy_fromio() functions do not provide sufficient control, so instead loop using ioread functions.

* w1: small type cleanup in sysfsDan Carpenter2014-02-151-2/+2
| | | | | | | | | | | | | On 64 bit systems, a large value for "long tmp" is truncated when assigning to "int md->max_slave_count" so we still end up with a value less than one despite the "tmp < 1" check.

* FMC: support carriers with no mezzanineAlessandro Rubini2014-02-151-6/+1
| | | | | | | | | | | | | | | | | At registration and unregistration time, I was checking fmc->flags for FMC_DEVICE_NO_MEZZANINE, to skip initialization and cleanup for empty slots. The check was wrong ("==" instead of "&") but registration failed anyways (as expected) because we had no EEPROM. This commit fixes one such checks and removes the other, so to actually accept slots with no mezzanines. That's because the carrier may offer some support anyways (the SPEC does), and working on the carrier with no mezzanine-specific driver is common during development.

* /dev/mem: handle out-of-bounds read/writePetr Tesarik2014-02-151-0/+6
| | | | | | | | | | | | | | | | | The loff_t type may be wider than phys_addr_t (e.g. on 32-bit systems). Consequently, the file offset may be truncated in the assignment. Currently, /dev/mem wraps around, which may cause applications to read or write incorrect regions of memory by accident. Let's follow POSIX file semantics here and return 0 when reading from and -EFBIG when writing to an offset that cannot be represented by a phys_addr_t. Note that the conditional is optimized out by the compiler if loff_t has the same size as phys_addr_t.

| | | | | | | | | | | | | | | | | | | | | | | | | | Similar to what was done for the lm75 driver. Add depends on THERMAL since that is what provides the register/unregister functions above, but only if THERMAL_OF was selected as this is an optional feature of the driver.

Fix SENSORS_LM75 dependencies to eliminate build errors: drivers/built-in.o: In function `lm75_remove': lm75.c:(.text+0x12bd8c): undefined reference to `thermal_zone_of_sensor_unregister' drivers/built-in.o: In function `lm75_probe': lm75.c:(.text+0x12c123): undefined reference to `thermal_zone_of_sensor_register' Add depends on THERMAL since that is what provides the register/unregister functions above, but only if THERMAL_OF was selected as this is an optional feature of the driver.
