i2c: designware_i2c: Add support for PCI(e) based I2C cores (x86)

2016-04-25T05:31:58+00:00

This patch adds support for the PCI(e) based I2C cores. Which can be
found for example on the Intel Bay Trail SoC. It has 7 I2C controllers
implemented as PCI devices.

This patch also adds the fixed values for the timing registers for
BayTrail which are taken from the Linux designware I2C driver.

i2c: designware_i2c: Add DM support

2016-04-25T05:31:48+00:00

This patch adds DM support to the designware I2C driver. It currently
supports DM and the legacy I2C support. The legacy support should be
removed, once all platforms using it have DM enabled.

i2c: designware_i2c: Prepare for DM driver conversion

2016-04-25T05:31:38+00:00

This patch prepares the designware I2C driver for the DM conversion.
This is mainly done by removing struct i2c_adapter from the functions
that shall be used by the DM driver version as well.

i2c: designware_i2c: Integrate set_speed() into dw_i2c_set_bus_speed()

2016-04-25T05:31:28+00:00

Integrating set_speed() into dw_i2c_set_bus_speed() will make the
conversion to DM easier for this driver.

i2c: designware_i2c: Add dw_i2c_enable() helper function

2016-04-25T05:31:16+00:00

dw_i2c_enable() is used to dis-/en-able the I2C controller. It makes
sense to add such a function, as the controller is dis-/en-abled
multiple times in the code. Additionally, this function now checks,
if the controller is really dis-/en-abled. This code is copied
from the Linux I2C driver version.

i2c: designware_i2c: Add ic_enable_status to ic_regs struct

2016-04-25T05:31:04+00:00

Add the ic_enable_status register to the i2c_regs struct. Additionally
the register offsets are added, to better check, if the offset matches
the register description in the datasheet.

dm: i2c: Add driver for Cadence I2C IP

2016-04-13T16:29:07+00:00

This is a possible drop in replacement for drivers/i2c/zynq-i2c.c

Since this is cadence IP it has been renamed to cdns-i2c,
to make sense with the compatible string.

i2c: uniphier: use devm_get_addr() to get base address

2016-03-31T15:17:13+00:00

Currently, fdtdec_get_addr_size() does not support the address
translation, so it cannot handle device trees with non-straight
"ranges" properties.  (This would be a problem with DTS for UniPhier
ARMv8 SoCs.)
