* zephyr: Move ADC-shim code into zephyr/shimSimon Glass2021-04-071-18/+1
| | | | | | | | | | | | | | | | | | | Most of the shim code is in zephyr/ rather than in the ECOS code. Move the ADC one as well, to keep it consistent.

* zephyr: add shim ADCDawid Niedzwiecki2021-02-091-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Add ADC shim to connect the platform/ec ADC API to the Zephyr ADC API. Generate needed global variables/types: enum adc_channel and adc_channels from dts. Once ADC_CMD config is enabled, it replaces the "adc" Zephyr console function. The shim assues only ADC_0 module. More specific channel options can be added to named-adc.yaml e.g. shift or gain.

* servo_v4: Fix ADC console commandNick Sanders2016-05-261-12/+0
| | | | | | | | | | | | | | | | | | | | | | The console adc command prints adc values in the order they appear in hardware, however they are lableled in the order they are enumerated in board.h, which is not necessarily the same. This prints the correct name and value pairs, and removes the adc_read_all_channels function which is not otherwise used. BUG=chromium:571476 BRANCH=None TEST="adc" command associates correct values with names now.
