Basic MFD framework for the MSP430 microcontroller firmware used
on the dm355evm board:
- Provides an interface for other drivers: register read/write
utilities, and register declarations.
- Directly exports:
* Many signals through the GPIO framework
+ LEDs
+ SW6 through gpio sysfs
+ NTSC/nPAL jumper through gpio sysfs
+ ... more could be added later, e.g. MMC signals
* Child devices:
+ LEDs, via leds-gpio child (and default triggers)
+ RTC, via rtc-dm355evm child device
+ Buttons and IR control, via dm355evm_keys
- Supports power-off system call. Use the reset button to power
the board back up; the power supply LED will be on, but the
MSP430 waits to re-activate the regulators.
- On probe() this:
* Announces firmware revision
* Turns off the banked LEDs
* Exports the resources noted above
* Hooks the power-off support
* Muxes tvp5146 -or- imager for video input
Unless the new tvp514x driver (tracked for mainline) is configured,
this assumes that some custom imager driver handles video-in.
This completely ignores the registers reporting the output voltages
on the various power supplies. Someone could add a hwmon interface
if that seems useful.
