2021-01-08soc/intel/common: Pass in pci_devfn_t into lpss_set_power_stateFurquan Shaikh
This change updates the parameter passed into `lpss_set_power_state()` from struct device * to pci_devfn_t. This allows the users in the early stages to use pci_devfn_t instead of having to walk the device tree to get a pointer to the relevant device structure. It is important for optimizing out unnecessary components of the device tree from the early stages.

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2017-08-18Reinvent I2C opsNico Huber
Do not use the global platform_i2c_transfer() function that can only be implemented by a single driver. Instead, make a `struct device` aware transfer() function the only interface function for I2C controller dri- vers to implement. To not force the slave device drivers to be implemented either above generic I2C or specialized SMBus operations, we support SMBus control- lers in the slave device interface too. We start with four simple slave functions: i2c_readb(), i2c_writeb(), i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec- tive SMBus functions. But we keep aliases because it would be weird to force e.g. an I2C EEPROM driver to call smbus_read_byte().

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>

There is no need to generate ACPI tables for the device TEST=Verified that if an i2c device is disabled statically in devicetree or dynamically in mainboard, then coreboot does not die looking for missing resources.

In the intel/common/block * Move I2C common code from intel/common to intel/common/block. * Split the code into common, early init and post mem init stages and put it in lpss_i2c.c, i2c_early.c and i2c.c respectively. * Declare functions for getting platform specific i2c bus config and mapping bus to devfn and vice versa, that have to be implemented by SoC. In skylake/apollolake * Stop using code from soc/intel/common/lpss_i2c.c. * Remove early i2c initialization code from bootblock. * Refactor i2c.c file to implement SoC specific methods required by the I2C IP block.
