i2c: imx-lpi2c: add low power i2c bus driver

2016-12-01T22:44:13+00:00

This patch adds lpi2c bus driver to support new i.MX products which use lpi2c instead of the old imx i2c. The lpi2c can continue operating in stop mode when an appropriate clock is available. It is also designed for low CPU overhead with DMA offloading of FIFO register accesses. Signed-off-by: Gao Pan Reviewed-by: Fugang Duan Reviewed-by: Vladimir Zapolskiy Signed-off-by: Wolfram Sang

i2c: mlxcpld: add master driver for mellanox systems

2016-11-24T15:21:42+00:00

Device driver for Mellanox I2C controller logic, implemented in Lattice CPLD device. Device supports: - Master mode - One physical bus - Polling mode The Kconfig currently controlling compilation of this code is: drivers/i2c/busses/Kconfig:config I2C_MLXCPLD Signed-off-by: Michael Shych Signed-off-by: Vadim Pasternak Reviewed-by: Jiri Pirko Reviewed-by: Vladimir Zapolskiy Signed-off-by: Wolfram Sang

i2c: thunderx: Add i2c driver for ThunderX SOC

2016-08-25T22:41:55+00:00

The ThunderX SOC uses the same i2c block as the Octeon SOC. The main difference is that on ThunderX the device is a PCI device so device probing is done via PCI, interrupts are MSI-X. The clock rates can be set via device tree or ACPI. Signed-off-by: Jan Glauber Signed-off-by: Wolfram Sang

i2c: octeon: Split the driver into two parts

2016-08-25T22:41:54+00:00

Move common functionality into a separate file in preparation of the re-use from the ThunderX i2c driver. Functions are slightly re-ordered but no other changes are included. Signed-off-by: Jan Glauber Signed-off-by: Wolfram Sang

i2c: octeon: Rename driver to prepare for split

2016-08-25T22:41:52+00:00

This is an intermediate commit in preparation of the driver split. The module rename in this commit will be reverted in the next patch, this is just done to make the series bisectible. Signed-off-by: Jan Glauber Signed-off-by: Wolfram Sang

i2c: uniphier_f: add UniPhier FIFO-builtin I2C driver

2015-10-23T19:55:46+00:00

Add support for on-chip I2C controller used on newer UniPhier SoCs such as PH1-Pro4, PH1-Pro5, etc. This adapter is equipped with 8-depth TX/RX FIFOs. Signed-off-by: Masahiro Yamada Signed-off-by: Wolfram Sang

i2c: uniphier: add UniPhier FIFO-less I2C driver

2015-10-23T19:55:45+00:00

Add support for on-chip I2C controller used on old UniPhier SoCs such as PH1-LD4, PH1-sLD8, etc. This adapter is so simple that it has no FIFO in it. Signed-off-by: Masahiro Yamada Signed-off-by: Wolfram Sang

i2c: lpc2k: add driver

2015-08-24T12:05:18+00:00

Add support for the I2C controller found on several NXP devices including LPC2xxx, LPC178x/7x and LPC18xx/43xx. The controller is implemented as a state machine and the driver act upon the state changes when the bus is accessed. The I2C controller supports master/slave operation, bus arbitration, programmable clock rate, and speeds up to 1 Mbit/s. Signed-off-by: Joachim Eastwood Signed-off-by: Wolfram Sang

i2c: emev2: add driver

2015-08-10T06:37:29+00:00

Add a basic driver for the Renesas EMEV2 SoC. Based on the driver from the BSP which was first worked on by Ian, and made ready for upstream by me. Signed-off-by: Ian Molton Reviewed-by: Laurent Pinchart Signed-off-by: Wolfram Sang Signed-off-by: Wolfram Sang
