-[TOC]
-
-## Overview
-
-The 45W USB Type-C charging adapter control board implements the controls for a
-charging adapter for a USB Type-C enabled device.
-
-## Hardware Capabilities
-
-This board provides the following features, to enable USB Type-C based power
-charger design:
-
-* BMC (Biphase Mark Coding) used for USB PD (Power Delivery)
- communication over the CC wire
-* Support 20V/12V/5V@ 2.25A and up to 45W
-* Support OCP (Over Current Protection) / OVP (Over Voltage
- Protection) at adapter's secondary side

-For schematic, see the attached file at the bottom of this page.
-
-## Firmware Source Code
-
-The firmware is located In the Chromium Embedded Controller repository under
-*[board/zinger/](https://chromium.googlesource.com/chromiumos/platform/ec/+/HEAD/board/zinger/)*
-:
-
-<https://chromium.googlesource.com/chromiumos/platform/ec/+/HEAD/board/zinger/>
-
-### Building Firmware
-
-Within your Chromium OS chroot, the syntax is:
-
-```none
-cd ~/trunk/src/platform/ec
-make BOARD=zinger
-```
-
-### Flashing Firmware
-
-The firmware is normally flashed via the kernel, as part of the Chrome OS
-Auto-Update process. Payloads are located in `/lib/firmware/cros-pd`.
-
-When the adapter is connected to a Chrome device, you can manually flash the
-read-write firmware as follows:
-
-```none
-ectool --cros_pd flashpd 4 <port> /tmp/zinger.ec.RW.bin
-```
-
-The device must be in developer mode to run the `ectool` command. After running
-this command, the firmware is located in
-`~/trunk/src/platform/ec/build/zinger/ec.bin` \ No newline at end of file
