dm: i2c: add i2c-gpio driver

2015-04-18T17:11:17Z

This commit adds driver model support to software emulated i2c bus driver. This driver supports kernel-style device tree bindings. Fdt properties in use: - compatible - "i2c-gpio" - gpios - data and clock GPIO pin phandles - delay-us - micro seconds delay between GPIOs toggle operations, which is 1/4 of I2C speed clock period. Added: - Config: CONFIG_DM_I2C_GPIO - File: drivers/i2c/i2c-gpio.c - File: doc/device-tree-bindings/i2c/i2c-gpio.txt Driver base code is taken from: drivers/i2c/soft-i2c.c, changes: - use "i2c-gpio" naming - update comments style - move preprocesor macros into functions - add device tree support - add driver model i2c support - code cleanup, - add Kconfig entry Signed-off-by: Przemyslaw Marczak Acked-by: Simon Glass Added braces in i2c_gpio_xfer() to fix style nit: Signed-off-by: Simon Glass

dm: i2c: Add a compatbility layer

2015-01-30T00:09:53Z

For boards which use multiple I2C devices, or for SOCs which support multiple boards, we might want to convert these to driver model at different times. At present this is difficult because we need to either use CONFIG_DM_I2C for a board or not. Add a compatibility layer which implements the old API, thus allowing a board to move to driver model for I2C without requiring that everything it uses is moved in the same commit.

This driver includes some test features such as only supporting certain bus speeds. It passes its I2C traffic through to an emulator. Acked-by: Heiko Schocher Signed-off-by: Simon Glass Reviewed-by: Masahiro Yamada

dm: i2c: Add I2C emulation driver for sandbox

2014-12-11T20:18:42Z

In order to test I2C we need some sort of emulation interface. Add hooks to allow a driver to emulate an I2C device for sandbox. Signed-off-by: Simon Glass Acked-by: Heiko Schocher Reviewed-by: Masahiro Yamada

dm: i2c: Add a uclass for I2C

2014-12-11T20:18:42Z

The uclass implements the same operations as the current I2C framework but makes some changes to make it fit driver model better: - Remove the chip address from API calls - Remove the address length from API calls - Remove concept of 'current' I2C bus - Drop all existing init functions Acked-by: Heiko Schocher Reviewed-by: Masahiro Yamada Signed-off-by: Simon Glass

i2c: designware: Convert driver to multibus/multiadapter framework

2014-10-29T07:56:23Z

In preparation for the SoCFPGA support of the designware I2C driver, convert this driver to the common CONFIG_SYS_I2C framework. This patch converts all users of this driver, this is: - ST spearxxx boards - AXS101 (ARC700 platform) I couldn't test this patch on those boards. Only compile tested for all spear boards. And tested on SoCFPGA. Signed-off-by: Stefan Roese Reviewed-by: Marek Vasut Acked-by: Alexey Brodkin Tested-by: Alexey Brodkin Cc: Heiko Schocher Cc: Vipin Kumar Cc: Jeroen Hofstee
