11 | Enable driver model for I2C. The I2C uclass interface: probe, read, |
12 | write and speed, is implemented with the bus drivers operations, | |
13 | which provide methods for bus setting and data transfer. Each chip | |
14 | device (bus child) info is kept as parent platdata. The interface | |
15 | is defined in include/i2c.h. When i2c bus driver supports the i2c | |
16 | uclass, but the device drivers not, then DM_I2C_COMPAT config can | |
17 | be used as compatibility layer. | |

23 | Enable old-style I2C functions for compatibility with existing code. | |
24 | This option can be enabled as a temporary measure to avoid needing | |
25 | to convert all code for a board in a single commit. It should not | |
26 | be enabled for any board in an official release. | |

29 | tristate "Chrome OS EC tunnel I2C bus" | |
30 | depends on CROS_EC | |
31 | help | |
32 | This provides an I2C bus that will tunnel i2c commands through to | |
33 | the other side of the Chrome OS EC to the I2C bus connected there. | |
34 | This will work whatever the interface used to talk to the EC (SPI, | |
35 | I2C or LPC). Some Chromebooks use this when the hardware design | |
36 | does not allow direct access to the main PMIC from the AP. | |

38 | config I2C_CROS_EC_LDO |
39 | bool "Provide access to LDOs on the Chrome OS EC" | |
40 | depends on CROS_EC | |
41 | ---help--- | |
42 | On many Chromebooks the main PMIC is inaccessible to the AP. This is | |
43 | often dealt with by using an I2C pass-through interface provided by | |
44 | the EC. On some unfortunate models (e.g. Spring) the pass-through | |
45 | is not available, and an LDO message is available instead. This | |
46 | option enables a driver which provides very basic access to those | |
47 | regulators, via the EC. We implement this as an I2C bus which | |
48 | emulates just the TPS65090 messages we know about. This is done to | |
49 | avoid duplicating the logic in the TPS65090 regulator driver for | |
50 | enabling/disabling an LDO. | |

443 | Support for Tegra I2C controllers managed by the BPMP (Boot and | |
444 | Power Management Processor). On Tegra186, some I2C controllers are | |
445 | directly controlled by the main CPU, whereas others are controlled | |
446 | by the BPMP, and can only be accessed by the main CPU via IPC | |
447 | requests to the BPMP. This driver covers the latter case. | |
