Lubomir Rintel 4e6d273940 Platform: OLPC: Add a config menu category for XO 1.75
Randy Dunlap says:

  drivers/platform/olpc/Kconfig needs to use "menuconfig" like all of the
  other Kconfig files in drivers/platform/ so that its menu is listed in
  the correct place in *config interfaces.

Otherwise he's sad.

Lubomir Rintel af21f32c78 Platform: OLPC: Require CONFIG_POWER_SUPPLY for XO-1.75 EC
ERROR: "power_supply_put" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!
  ERROR: "power_supply_changed" [drivers/platform/olpc/olpc-xo175-ec.ko] undefined!

Adding the dependency seems like a more reasonable thing compared to
ifdef-ing the bits, as if one has an XO-1.75 they almost certainly want
a baterry and AC adapter support.

We should depends on CONFIG_SPI_SLAVE other than directly select it.

Lubomir Rintel 0c3d931b3a Platform: OLPC: Add XO-1.75 EC driver
It's based off the driver from the OLPC kernel sources. Somewhat
modernized and cleaned up, for better or worse.

Modified to plug into the olpc-ec driver infrastructure (so that battery
interface and debugfs could be reused) and the SPI slave framework.
