**ESP8089 Linux driver**

v1.9 imported from the Rockchip Linux kernel github repo

Modified to build as a standalone module for SDIO devices.


## Building:

    make
    sudo make install

## Using:

modprobe should autoload the module as the ESP8089 should be detected by
the SDIO driver and loaded as a dependency.

The ESP8089 requires that the CH_PD signal be reset before the driver
can load properly, so a GPIO is used by the driver to assert this signal
for 200ms.  The GPIO defaults to 0 (ID_SD on the Raspberry Pi) but this
can be changed to any GPIO mapped by the kernel GPIO driver through the
esp_reset_gpio module parameter.  This can be accomplished by creating a
new modprobe.d config file.  For example, to use GPIO 5 instead, create
as root /etc/modprobe.d/esp.conf and add the line:

    options esp8089 esp_reset_gpio=5

which changes the GPIO from 0 to 5.


## Building a Debian source package:

To build a source package for release, first install the following:

    apt-get install debhelper dkms raspberrypi-kernel-headers

Then build the package:

    sudo make dkmsdeb

The module will be named `esp8089-dkms_*.deb`.  Don't forget to update the version
in dkms.conf and committing before making a release!

If the build fails to create a source package, try installing dkms from github:

    sudo apt-get remove dkms
    sudo apt-get install devscripts quilt
    git clone https://github.com/dell/dkms.git
    cd dkms
    sed -ie "s/module-init-tools/kmod/g" debian/control
    make debs

and install the resulting package in dist/
