dt-bindings: mfd: bd71828: Use charger resistor in mOhm instead of MOhm

8ece9d24 · Andreas Kemnade <[email protected]> · 2024-11-11 11:27:01 +01:00

Apparently there was some confusion regarding milliohm vs. megaohm.
(m/M). Use microohms to be able to properly specify the charger
resistor like other drivers do. This is not used yet by mainline code
yet. Specify a current sense resistor in milliohms range rather then
megaohms range in the examples.
