| Subject: [PATCH 1112/1795] ARM: dts: marzen: Add SDHI0 VCCQ Regulator |
| |
| Add support for the on-board voltage regulator hooked up to GPIO3_20 |
| on r8a7779 Marzen. The board schematics describes the regulator as U4 |
| TPS2110A. Input wise, U4 has D0 fixed to ground, D1 tied to GPIO3_20 |
| while IN1 is fixed to 3.3V and IN2 is fixed to 1.8V. OUT goes to the |
| pull-ups for the data pins of SDHI0. |
