| Subject: arm64: dts: apq8016-sbc: Increase load on l11 for SDCARD |
| |
| From: Loic Poulain <loic.poulain@linaro.org> |
| |
| [ Upstream commit af61bef513ba179559e56908b8c465e587bc3890 ] |
| |
| In the same way as for msm8974-hammerhead, l11 load, used for SDCARD |
| VMMC, needs to be increased in order to prevent any voltage drop issues |
| (due to limited current) happening with some SDCARDS or during specific |
| operations (e.g. write). |
| |
| Tested on Dragonboard-410c and DART-SD410 boards. |
| |
| Fixes: 4c7d53d16d77 (arm64: dts: apq8016-sbc: add regulators support) |
