| 8 | commit 56b5d4ea778c1b0989c5cdb5406d4a488144c416 upstream. | |
| 9 | ||
| 10 | LDO35 uses 25 mV step, not 50 mV. Bucks 7 and 8 use 12.5 mV step | |
| 11 | instead of 6.25 mV. Wrong step caused over-voltage (LDO35) or | |
| 12 | under-voltage (buck7 and 8) if regulators were used (e.g. on Exynos5420 | |
| 13 | Arndale Octa board). | |
