i2c: mv64xxx: Document the newly introduced Armada XP A0 compatible

2014-02-06T19:22:19Z

commit f8b94beb7e6a374cb0de531b72377c49857b35ca upstream. The first variants of Armada XP SoCs (A0 stepping) have issues related to the i2c controller which prevent to use the offload mechanism and lead to a kernel hang during boot. The commit introduces a new the compatible string marvell,mv78230-a0-i2c for the i2c controller.

i2c: imx: use exact SoC revision to document binding

use exact SoC revision instead of wildcard describing the compatible property requirement in the binding document. This will make the binding more clearer. Signed-off-by: Jingchang Lu Acked-by: Shawn Guo Signed-off-by: Wolfram Sang

i2c: mv64xxx: Add I2C Transaction Generator support

2013-08-23T08:15:50Z

The I2C Transaction Generator offloads CPU from managing I2C transfer step by step. This feature is currently only available on Armada XP, so usage of this mechanism is activated through device tree. Based on the work of Piotr Ziecik and rewrote to use the new way of handling multiples i2c messages. Signed-off-by: Piotr Ziecik Signed-off-by: Gregory CLEMENT Signed-off-by: Wolfram Sang

Pull i2c updates from Wolfram Sang: - new drivers: Kontron PLD, Wondermedia VT - mv64xxx driver gained sun4i support and a bigger cleanup - duplicate driver 'intel-mid' removed - added generic device tree binding for sda holding time (and designware driver already uses it) - we tried to allow driver probing with only device tree and no i2c ids, but I had to revert it because of side effects. Needs some rethinking. - driver bugfixes, cleanups... * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: (34 commits) i2c-designware: use div_u64 to fix link i2c: Kontron PLD i2c bus driver i2c: iop3xxx: fix build failure after waitqueue changes i2c-designware: make SDA hold time configurable i2c: mv64xxx: Set bus frequency to 100kHz if clock-frequency is not provided i2c: imx: allow autoloading on dt ids i2c: mv64xxx: Fix transfer error code i2c: i801: SMBus patch for Intel Coleto Creek DeviceIDs i2c: omap: correct usage of the interrupt enable register i2c-pxa: prepare clock before use Revert "i2c: core: make it possible to match a pure device tree driver" i2c: nomadik: allocate adapter number dynamically i2c: nomadik: support elder Nomadiks i2c: mv64xxx: Add Allwinner sun4i compatible i2c: mv64xxx: make the registers offset configurable i2c: mv64xxx: Add macros to access parts of registers i2c: vt8500: Add support for I2C bus on Wondermedia SoCs i2c: designware: fix race between subsequent xfers i2c: bfin-twi: Read and write the FIFO in loop i2c: core: make it possible to match a pure device tree driver ...
