Hi everyone,
This series adds more support for axp818 regulators, and USB support for A83T. Normal EHCI/OHCI USB works, and so does OTG host mode. I couldn't get my Cubietruck Plus to work in gadget mode though. No USB device appears on the host end when it enters fastboot.
Patch 1 removes axp818_init() from the header file, as it is undefined and unused.
Patch 2 fixes axp818's DCDC5 default voltage. DCDC5 normally supplies DRAM. This changes the default to match DDR3 DRAM.
Patch 3 adds support for axp818's FLDOs, one of which powers the HSIC PHY.
Patch 4 raises the DCDC1 voltage on h8_homlet_v2 to 3.3V, the default value.
Patch 5 enables and sets DLDO4 to 3.3V on h8_homlet_v2. This powers the AC200 chip, which among other things, is the ethernet PHY.
Patch 6 adds support for the USB PHYs on A83T.
Patch 7 fixes some clock macros related to USB PHYs for A83T.
Patch 8 & 9 add A83T compatible strings to sunxi EHCI & OHCI.
Patch 10 adds support for A83T to musb sunxi glue.
Patch 11 generalizes the VBUS function related macros for AXP PMICs.
Patch 12 adds support for VBUS drive on AXP818.
Patch 13 enables USB Kconfig options in h8_homlet_v2_defconfig.
Patch 14 enables USB Kconfig options in Cubietruck_plus_defconfig.
Patch 15 ~ 17 is the minimal changes needed to enable USB on the A83T boards I have. They are not the same as the kernel changes I will submit, and should not be merged without discussion.
