From: Konstantin Porotchkin <redacted> Replace wrong regulator in AP0 eMMC definition on MacchiatoBIN board with 3.3V regulator. The MacchiatoBIN board has no 1.8V regulator connected to AP0 eMMC (ap0_sdhci0) interface.There seems to be some variability between Macchiatobin versions according to the schematics. The VDDO_H supply is connected to the eMMC VCCQ pins, and is also connected to the AP_VDDO_H pins. It is wired to the 1.8V regulator on rev 1.1 schematics, but hard-wired to the 3.3V regulator on rev 1.3 schematics. This needs clarification from SolidRun before the patch can be accepted - was VDDO_H ever wired to the 1.8V regulator on production hardware?[KP] I will try to find a relevant contact in SolidRun for get this issue clarified.
I've already added Jon Nettleton. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
