2016-06-03ARM: dts: sun6i: primo81: Drop constraints on dc1sw regulatorChen-Yu Tsai
This is the same issue fixed in commit dcf5341f0150 ("ARM: dts: sun8i-q8-common: Do not set constraints on dc1sw regulator"). Commit message copied: dc1sw is an on/off only regulator and as such it cannot have constraints. This is a limitation of the kernel regulator implementation which resolves supplies on the first regulator_get(), which is done after applying constraints, and applying the constrains will fail because it calls _regulator_get_voltage() and _regulator_do_set_voltage() both of which will fail on a switch regulator when there is no supply (yet). This causes registering of all axp22x regulators to fail with the following errors: [ 1.395249] vcc-lcd: failed to get the current voltage(-22) [ 1.405131] axp20x-regulator axp20x-regulator: Failed to register dc1sw [ 1.412436] axp20x-regulator: probe of axp20x-regulator failed with error -22 This commit removes the constrains on dc1sw / vcc-lcd fixing this problem. Note that dcdc1 itself is contrained to the exact same values, so this does not change anything.

2015-11-17ARM: dts: sunxi: sun6i-a31s-primo81.dts: add touchscreen axis swapping propertyKarsten Merker
The MSI Primo81 has a display in portrait mode but a touchscreen in landscape mode. To have both of them use the same coordinate system, the touchscreen-swapped-x-y property has to be set for the touchscreen.

2015-10-23ARM: dts: sun6i: Add dts file for MSI Primo81 tabletKarsten Merker
The MSI Primo81 is an A31s based tablet, with 1G RAM, 16G NAND, 768x1024 IPS LCD display, mono speaker, 0.3 MP front camera, 2.0 MP rear camera, 3500 mAh battery, gt911 touchscreen, mma8452 accelerometer and rtl8188etv usb wifi. Has "power", "volume+" and "volume-" buttons (both volume buttons are also connected to the UBOOT_SEL pin). The external connectors are represented by MicroSD slot, MiniHDMI, MicroUSB OTG and 3.5mm headphone jack. USB OTG is enabled in host only mode. AXP221 USB power supply and GPIO support are required for full USB OTG support.
