This contains all of the changes to /arch/arm/ from the ev3dev v3.16 kernel branch.
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. Signed-off-by: David Lechner <[email protected]>
ev3dev: doing this so we don't waste space in the kernel command line. This is the same as setting fbcon=margin:7
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.
