This is needed to correctly display the boot logo with a white
background on a monochrome display.

The lms2012 software expects USB to be able to handle 1024 byte packets
on USB ep1. There is no existing configuration for this in the kernel,
so we have to add our own.

The maxpacket values come from the official LEGO firmware source code:
https://github.com/mindboards/ev3sources/blob/master/extra/linux-03.20.00.13/drivers/usb/musb/musb_core.c#L1065

Issue: ev3dev/lms2012-compat#49

Publicly expose functions for detecting devices and removing detected
devices.

Currently an i2c adapter only probes/detects new devices when the adapter
is added or when a new i2c driver is added. This adds a new function,
i2c_adapter_probe(), that allows detecting sensors at any time.

Furthermore, the function i2c_adapter_remove_probed() is added to remove
the devices added by i2c_adapter_probe() at any time.

The intended use of these functions is for LEGO MINDSTORMS sensors. These
are hot-plugable I2C devices. When a sensor is connected, i2c_adapter_probe()
is called to automatically configure the sensor. When the sensor is
disconnected, i2c_adapter_remove_probed() is called to remove the
automatically configured device.

ev3dev: doing this so we don't waste space in the kernel command line.
This is the same as setting fbcon=margin:7

…quency

this helps improve EV3 UART sensors overflowing the hardware FIFO
at the expense of more CPU usage

We need to poll the ADC every 100ms, so add a hrtimer tirgger
when the driver is probed.

EV3 doesn't have enough CPU power to handle more frequent polling

This adds a special handler to the default remoteproc ELF firmware
loader that looks up the memory page on TI PRU firmware files.

These processors have multiple memory maps that share the same address
space, so we need to know the page in addition to the physical address
in order to translate the address to a local CPU address.
