* adc: Remove adc_chip.h where adc.h is usedCaveh Jalali2021-08-271-1/+0
| | | | | | | | | | | | | | This removes the use of adc_chip.h where adc.h is also used. In this case, adc_chip.h is redundant.

* ec.tasklist: Consolidate duplicate commentsDaisuke Nojiri2019-04-081-11/+1
| | | | | | | | | | | | | | | | | | | | | | | It's simply a bad idea to describe a macro in multiple locations. It'll make it hard to change. It'll be difficult to keep all locations in sync. This patch replaces the comment duplicated in all ec.tasklist with a pointer to the CONFIG_TASK_LIST definition. The macro will be described in a single place (just like all/most other macros).

* usb_i2c: Fail if board I2C bridge is disabledRandall Spangler2017-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add usb_i2c_board_is_enabled(). On Cr50, this is now also connected to the I2C CCD capability. The USB-I2C bridge can only be used when the capability is available. On other platforms (Servo V4, etc.) where usb_i2c_board_enable() is a no-op, add a dummy implementation which always returns true. See go/cr50-ccd-wp for more information.

tigertail allows muxing a usb-c port onto two different passthough targets. This allows for automated switching between USB host and device without DUT or endpoint knowledge. tigertail also routes SBU lines to stm32 UART, and has INAs on VBUS and VCONN to measure power.
