Documentation: dt: i2c: use correct STMicroelectronics vendor prefix

2016-07-22T19:51:33Z

The documentation currently uses the non-standard vendor prefix stm and st-micro for STMicroelectronics. The drivers do not specify the vendor prefixes since the I2C Core strips them away from the DT provided compatible string. Therefor, changing documentation and existing device trees does not have any impact on device detection. Signed-off-by: Stefan Agner Acked-by: Wolfram Sang Signed-off-by: Rob Herring

tpm: Add TPM 2.0 support to the Nuvoton i2c driver (NPCT6xx family)

2016-07-19T14:43:38Z

The command flow is exactly the same, the core simply needs to be told to enable TPM2 mode when the compatible string indicates a TPM2.

i2c: Add generic support passing secondary devices addresses

2016-06-13T20:32:09Z

Some I2C devices have multiple addresses assigned, for example each address corresponding to a different internal register map page of the device. So far drivers which need support for this have handled this with a driver specific and non-generic implementation, e.g. passing the additional address via platform data. This patch provides a new helper function called i2c_new_secondary_device() which is intended to provide a generic way to get the secondary address as well as instantiate a struct i2c_client for the secondary address. The function expects a pointer to the primary i2c_client, a name for the secondary address and an optional default address. The name is used as a handle to specify which secondary address to get. The default address is used as a fallback in case no secondary address was explicitly specified. In case no secondary address and no default address were specified the function returns NULL. For now the function only supports look-up of the secondary address from devicetree, but it can be extended in the future to for example support board files and/or ACPI.

2016-05-20T00:48:12Z

Pull i2c updates from Wolfram Sang: - Peter Rosin did some major rework on the locking of i2c muxes by seperating parent-locked muxes and mux-locked muxes. This avoids deadlocks/workarounds when the mux itself needs i2c commands for muxing. And as a side-effect, other workarounds in the media layer could be eliminated. Also, Peter stepped up as the i2c mux maintainer and will keep an eye on these changes. - major updates to the octeon driver - add a helper to the core to generate the address+rw_bit octal and make drivers use it - quite a bunch of driver updates * 'i2c/for-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (84 commits) i2c: rcar: add DMA support i2c: st: Implement bus clear i2c: only check scl functions when using generic recovery i2c: algo-bit: declare i2c_bit_quirk_no_clk_stretch as static i2c: tegra: disable clock before returning error [media] rtl2832: regmap is aware of lockdep, drop local locking hack [media] rtl2832_sdr: get rid of empty regmap wrappers [media] rtl2832: change the i2c gate to be mux-locked [media] si2168: change the i2c gate to be mux-locked iio: imu: inv_mpu6050: change the i2c gate to be mux-locked i2c: mux: document i2c muxes and elaborate on parent-/mux-locked muxes i2c: mux: relax locking of the top i2c adapter during mux-locked muxing i2c: muxes always lock the parent adapter i2c: allow adapter drivers to override the adapter locking i2c: uniphier: add "\n" at the end of error log i2c: mv64xxx: remove CONFIG_HAVE_CLK conditionals i2c: mv64xxx: use clk_{prepare_enable,disable_unprepare} i2c: mv64xxx: handle probe deferral for the clock i2c: mv64xxx: enable the driver on ARCH_MVEBU i2c: octeon: Add workaround for broken irqs on CN3860 ...
