2017-08-18include/device: Split i2c.h into threeNico Huber
Split `i2c.h` into three pieces to ease reuse of the generic defi- nitions. No code is changed. * `i2c.h` - keeps the generic definitions * `i2c_simple.h` - holds the current, limited to one controller driver per board, devicetree independent I2C interface * `i2c_bus.h` - will become the devicetree compatible interface for native I2C (e.g. non-SMBus) controllers Change-Id: I382d45c70f9314588663e1284f264f877469c74d Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/20845 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>

2015-02-20drivers/xpowers/axp209: Adapt to new I²C APIAlexandru Gagniuc
Originally, axp209_(read|write) accessors relied on i2c_(read|write) to return the number of bytes transferred. This was changed in * cdb61a6 i2c: Replace the i2c API. to return an error code or 0 on success. This caused the AXP209 check to fail. Fix the accessors to account for this new behavior.

2015-02-14drivers/xpowers/axp209: Print a message when probing failsAlexandru Gagniuc
Probing is done by reading the ID register and comparing it to a known value. When there is a mismatch, print an error.

2014-12-16i2c: Replace the i2c API.Gabe Black
The new API is in use in depthcharge and is based around the "i2c_transfer" function instead of i2c_read and i2c_write. The new function takes an array of i2c_seg structures which represent each portion of the transfer after a start bit and before the stop bit. If there's more than one segment, they're seperated by repeated starts. Some wrapper functions have also been added which make certain common operations easy. These include reading or writing a byte from a register or reading or writing a blob of raw data. The i2c device drivers generally use these wrappers but can call the i2c_transfer function directly if the need something different. The tegra i2c driver was very similar to the one in depthcharge and was simple to convert. The Exynos 5250 and 5420 drivers were ported from depthcharge and replace the ones in coreboot. The Exynos 5420 driver was ported from the high speed portion of the one in coreboot and was straightforward to port back. The low speed portion and the Exynos 5250 drivers had been transplanted from U-Boot and were replaced with the depthcharge implementation. BUG=None TEST=Built and booted on nyan with and without EFS.
