X-Git-Tag: 1.9.1~1^2~92
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=2c19d410f9d6ff1075ea2de0c0ad7b6a84e1e378;ds=sidebyside

altos/telefireone-v2.0: Definitions needed for MAX6691 driver

Fix the DMA channel definition (STM starts values at 1 for unknown reasons).
Add definition of the power enable bit for the timer.
