# I2C subsystem configuration

i2c: Create a new Kconfig for I2C At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason CONFIG_I2C is not strictly necessary is that: a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible i2c stacks b) In U-Boot proper, we always build drivers/i2c/ regardless of the options Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to SPL/TPL, so we can (in a future commit) simplify the Makefile rules. Enable it by default, since as above, we have separate options (SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled. Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.

Note:
This is a stand-in for an option to enable I2C support. In fact this
simply enables building of the I2C directory for U-Boot. The actual
I2C feature is enabled by DM_I2C (for driver model) and
the #define CONFIG_SYS_I2C_LEGACY (for the legacy I2C stack).
So at present there is no need to ever disable this option.
Eventually it will:
Enable support for the I2C (Inter-Integrated Circuit) bus in U-Boot.
I2C works with a clock and data line which can be driven by a
one or more masters or slaves. It is a fairly complex bus but is
widely used as it only needs two lines for communication. Speeds of
400kbps are typical but up to 3.4Mbps is supported by some
hardware. Enable this option to build the drivers in drivers/i2c as
part of a U-Boot build.

dm: cros_ec: Convert the I2C tunnel code to use driver model The Chrome OS EC supports tunnelling through to an I2C bus on the EC.

Add an I2C driver which tunnels through to the EC. Adjust the EC code to support binding child devices so that it can be set up. Adjust the existing I2C xfer function to fit driver model better. For now the old code remains to allow things to still work. It will be removed in a later patch once the new flow is fully enabled. Signed-off-by: Simon Glass <sjg@chromium.org>

help
This provides an I2C bus that will tunnel i2c commands through to
the other side of the Chrome OS EC to the I2C bus connected there.
This will work whatever the interface used to talk to the EC (SPI,
I2C or LPC). Some Chromebooks use this when the hardware design
does not allow direct access to the main PMIC from the AP.
cros_ec: Support the LDO access method used by spring Add a driver to support the special LDO access used by spring. This is a custom method in the cros_ec protocol - it does not use an I2C pass-through. There are two implementation choices: 1. Write a special LDO driver which can talk across the EC. Duplicate all the logic from TPS65090 for retrying when the LDO fails to come up. 2. Write a special I2C bus driver which pretends to be a TPS65090 and transfers reads and writes using the LDO message. Either is distasteful. The latter method is chosen since it results in less code duplication and a fairly simple (30-line) implementation of the core logic. The crosec 'ldo' subcommand could be removed (since i2c md/mw will work instead) but is retained as a convenience. Signed-off-by: Simon Glass <sjg@chromium.org>

config I2C_CROS_EC_LDO
bool "Provide access to LDOs on the Chrome OS EC"

---help---
On many Chromebooks the main PMIC is inaccessible to the AP. This is
often dealt with by using an I2C pass-through interface provided by
the EC. On some unfortunate models (e.g. Spring) the pass-through
is not available, and an LDO message is available instead. This
option enables a driver which provides very basic access to those
regulators, via the EC. We implement this as an I2C bus which
emulates just the TPS65090 messages we know about. This is done to
avoid duplicating the logic in the TPS65090 regulator driver for
enabling/disabling an LDO.

i2c: Add a DM_I2C driver for the sun6i P2WI controller This bus controller is used to communicate with an X-Powers AXP PMIC. Currently, various drivers access PMIC registers through a platform- specific non-DM "pmic_bus" interface, which depends on the legacy I2C framework. In order to convert those drivers to use DM_PMIC, this bus needs a DM_I2C driver. Refactor the p2wi functions to take the base address as a parameter, and implement both the existing interface (which is still needed in SPL) and the DM_I2C interface on top of them. The register for switching between I2C/P2WI/RSB mode is the same across all PMIC variants. Move that to the common header, so it can be used by both interface implementations.

Currently, various drivers access PMIC registers through a platform- specific non-DM "pmic_bus" interface, which depends on the legacy I2C framework. In order to convert those drivers to use DM_PMIC, this bus needs a DM_I2C driver.

The register for switching between I2C/P2WI/RSB mode is the same across all PMIC variants, so move that to the common header. There are only a couple of pairs of hardware/runtime addresses used across all PMIC variants. So far the code expected only the "primary" pair, but some PMICs like the AXP305 and AXP805 use the secondary pair, so add support for that to the DM driver as well.

The multiplexing mechanism is left to the driver to decide - it may be controlled by GPIOs, for example. The uclass supports only two methods: select() and deselect(). The current mux state is expected to be stored in the mux itself since it is the only thing that knows how to make things work. The mux can record the current state and then avoid switching unless it is necessary. So select() can be skipped if the mux is already in the correct state.

i2c: Create a new Kconfig for I2C At present we have CONFIG_SPL_I2C but not CONFIG_I2C. The reason CONFIG_I2C is not strictly necessary is that: a) We have CONFIG_SYS_I2C_LEGACY and CONFIG_DM_I2C for the two possible i2c stacks b) In U-Boot proper, we always build drivers/i2c/ regardless of the options Still, it is better to have CONFIG_I2C - it makes U-Boot proper similar to SPL/TPL, so we can (in a future commit) simplify the Makefile rules. Enable it by default, since as above, we have separate options (SYS_I2C_LEGACY and DM_I2C) to control whether it is 'really' enabled. Once we have migrated I2C to driver model, we can drop SYS_I2C_LEGACY and make DM_I2C become I2C. For now, this lets us simplify the Makefile rules.
