| Subject: [PATCH] ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |

| commit 636b45b8efa91db05553840b6c0120d6fa6b94fa upstream. |
| |
| The current set minimum voltage of 730000ยตV seems to be wrong. I don't |
| know the document which specifies that but the imx6qdl datasheets says |
| that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed, |
| lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp). |
