* 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.

* stm32: adc: Add support for DMA continuous modeShawn Nematbakhsh2015-12-211-1/+3
| | | | | | | | | | | | | | | | | | | Add support for continuously writing ADC samples to a circular buffer. CONFIG_ADC_PROFILE_FAST_CONTINUOUS should be defined and an appropriate sized buffer must be passed to adc_read_all_channels(). BUG=chromium:569994 TEST=Manual on snoball. Verify 'adc' continues to function (single mode). With pending commit, verify that continuous conversion interrupt is called at appropriate frequency and values look consistent.

* Fix ADC test for LM4Vic Yang2013-04-301-0/+2
| | | | | | | | | | | | | | | LM4 doesn't have implementation of adc_read_all_channels(). Let's use adc_read_channel() in this case. BUG=chrome-os-partner:18598 TEST=Build stress test for link.

* Clean up ADC moduleRandall Spangler2012-10-301-15/+15
| | | | | | | | | | | | | | ADC config structs are now chip-specific; this saves code size (several hundred bytes on LM4, since no need for 24-entry ADC channel to GPIO mapping table).
