ST7701 designed for small and medium sizes of TFT LCD display, is
capable of supporting up to 480RGBX864 in resolution. It provides
several system interfaces like MIPI/RGB/SPI.
Currently added support for Techstar TS8550B which is ST7701 based
480x854, 2-lane MIPI DSI LCD panel.
Driver now
Techstar TS8550B MIPI DSI panel is 480x854, 2-lane MIPI DSI LCD panel
with inbuilt ST7701 chip.
The default regulator names in ST7701 chip is renamed in Techstar TS8550B
so, add specific binding names for them.

The current axp20x names the ramping register 'scal' which probably
means scaling. Since the register really has nothing to do with
scaling, but really is the voltage ramp we rename it appropriately.

The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3.
This patch adds preliminary support for the regulator-ramp-delay property
for these 2 regulators. Note that the voltage ramp only works when
regulator is already enabled. E.g. when going

In the past, there have been words on various lists that if LDO3 is
disabled in u-boot, but enabled in the DTS, the axp209 driver would
fail to continue/hang. Several enable/disable patches have been
issues to devicetree's in both the kernel and u-boot to address
this

The OLinuXino Lime2 has a big capacitor on its LDO3 output. It is
actually too large, causing the PMIC to shutdown when toggling the LDO3.
By enabling soft-start and ramp delay we increase the time for the
capacitor to charge lowering the current drain on the power

This is a second edition of a series that implements voltage
ramping for AXP209 DCDC2 and LDO3 regulators and software
based soft-start for AXP209 LDO3 regulator.
Both features are needed to work around a PMIC shutdown when
toggling LDO3 on certain boards with high capacitance on the
LDO3 output.

The AXP209 supports ramping up voltages on several regulators such as
DCDC2 and LDO3, therefore we can use the standard 'regulator-ramp-delay'
property for those 2 regulators.
Note that the voltage ramp only works when the regulator is already
enabled. E.g. when going
Hi,
I frequently have to flash Allwinner devices (V40 based), and I am
wondering if anybody has figured out how to enter FEL mode via USB (without
pressing buttons, shorting pins, or using an SD card).
PhoenixSuit can do this, if you click "Upgrade" it will reboot to FEL mode.
Then, when it
