From 6906df1ab8d64a4e21d38ea538d6cd383a089e1d Mon Sep 17 00:00:00 2001 From: Siarhei Siamashka Date: Mon, 19 Jan 2015 05:23:30 +0200 Subject: sunxi: axp221: Add ELDO[1-3] support And also add Kconfig option for selecting ELDO3 voltage. The reason for having this option is that the Android kernel sets ELDO3 to 1.2V when powering up LCD in the case if 'lcd_if' configuration variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely to supply power for a SSD2828 chip. However on the MSI Primo81 tablet, which is using this particular 'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to be unnecessary and it works regardless. Having no schematics of this tablet, I can only guess that 1.2V is supplied to SSD2828 in some other way.
