git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: - the first series of making i2c_device_id optional instead of mandatory (in favor of alternatives like of_device_id). This involves adding a new probe callback (probe_new) which removes some peculiarities I2C had for a long time now. The new probe is matching the other subsystems now and the old one will be removed once all users are converted. It is expected to take a while but there is ongoing interest in that. - SMBus Host Notify introduced 4.9 got refactored. They are now using interrupts instead of the alert callback which solves multiple issues. - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux - significant refactoring for bcm2835 driver - the usual set of driver updates and improvements * 'i2c/for-4.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (46 commits) i2c: fsl-lpi2c: read lpi2c fifo size in probe() i2c: octeon: thunderx: Remove double-check after interrupt i2c: octeon: thunderx: TWSI software reset in recovery i2c: cadence: Allow Cadence I2C to be selected for Cadence Xtensa CPUs i2c: sh_mobile: Add per-Generation fallback bindings i2c: rcar: Add per-Generation fallback bindings i2c: imx-lpi2c: add low power i2c bus driver dt-bindings: i2c: imx-lpi2c: add devicetree bindings i2c: designware-pcidrv: Add 10bit address feature to medfield/merrifield i2c: pxa: Add support for the I2C units found in Armada 3700 i2c: pxa: Add definition of fast and high speed modes via the regs layout dt-bindings: i2c: pxa: Update the documentation for the Armada 3700 i2c: qup: support SMBus block read i2c: qup: add ACPI support i2c: designware: Consolidate default functionality bits i2c: i2c-mux-gpio: update mux with gpiod_set_array_value_cansleep i2c: mux: pca954x: Add ACPI support for pca954x i2c: use an IRQ to report Host Notify events, not alert i2c: i801: remove SMBNTFDDAT reads as they always seem to return 0 i2c: i801: use the BIT() macro for FEATURES_* also ...
2016-11-24i2c: use an IRQ to report Host Notify events, not alertBenjamin Tissoires1-4/+8
The current SMBus Host Notify implementation relies on .alert() to relay its notifications. However, the use cases where SMBus Host Notify is needed currently is to signal data ready on touchpads. This is closer to an IRQ than a custom API through .alert(). Given that the 2 touchpad manufacturers (Synaptics and Elan) that use SMBus Host Notify don't put any data in the SMBus payload, the concept actually matches one to one. Benefits are multiple: - simpler code and API: the client will just have an IRQ, and nothing needs to be added in the adapter beside internally enabling it. - no more specific workqueue, the threading is handled by IRQ core directly (when required) - no more races when removing the device (the drivers are already required to disable irq on remove) - simpler handling for drivers: use plain regular IRQs - no more dependency on i2c-smbus for i2c-i801 (and any other adapter) - the IRQ domain is created automatically when the adapter exports the Host Notify capability - the IRQ are assign only if ACPI, OF and the caller did not assign one already - the domain is automatically destroyed on remove - fewer lines of code (minus 20, yeah!)

2016-06-17i2c: smbus: add SMBus Host Notify supportBenjamin Tissoires1-0/+6
SMBus Host Notify allows a slave device to act as a master on a bus to notify the host of an interrupt. On Intel chipsets, the functionality is directly implemented in the firmware. We just need to export a function to call .alert() on the proper device driver. i2c_handle_smbus_host_notify() behaves like i2c_handle_smbus_alert(). When called, it schedules a task that will be able to sleep to go through the list of devices attached to the adapter. The current implementation allows one Host Notification to be scheduled while an other is running.

2016-05-04[media] rtl2832: change the i2c gate to be mux-lockedPeter Rosin1-1/+1
The root i2c adapter lock is then no longer held by the i2c mux during accesses behind the i2c gate, and such accesses need to take that lock just like any other ordinary i2c accesses do. So, declare the i2c gate mux-locked, and zap the regmap overrides that makes the i2c accesses unlocked and use plain old regmap accesses. This also removes the need for the regmap wrappers used by rtl2832_sdr, so deconvolute the code further and provide the regmap handle directly instead of the wrapper functions.

So, declare the i2c gate mux-locked, and zap the code that makes the unlocked i2c accesses and just use ordinary regmap_write accesses. This also happens to fix the deadlock described in http://patchwork.ozlabs.org/patch/584776/ authored by Adriana Reus <adriana.reus@intel.com> and submitted by Daniel Baluta <daniel.baluta@intel.com> ----------8<---------- iio: imu: inv_mpu6050: Fix deadlock between i2c adapter lock and mpu lock This deadlock occurs if the accel/gyro and the sensor on the auxiliary I2C (in my setup it's an ak8975) are working at the same time. Scenario: T1 T2 ==== ==== inv_mpu6050_read_fifo aux sensor op (eg. ak8975_read_raw) | | mutex_lock(&indio_dev->mlock) i2c_transfer | | i2c transaction i2c adapter lock | | i2c adapter lock i2c_mux_master_xfer | inv_mpu6050_select_bypass | mutex_lock(&indio_dev->mlock) When we operate on an mpu sensor the order of locking is mpu lock followed by the i2c adapter lock. However, when we operate the auxiliary sensor the order of locking is the other way around. ... ----------8<---------- The reason this patch fixes the deadlock is that T2 does not grab the i2c adapter lock until the very end (and grabs the newfangled i2c mux lock where it previously grabbed the i2c adapter lock).
