This changes the following mechanisms in the TC3589x device tree
probing path:
- Use the .of_match_table in struct device_driver to match the
device in the device tree.
- Add matches for the proper compatible strings "toshiba,..."
and all sub-variants, just as is done for the .id matches.
- Move over all the allocation of platform data etc to the
tc3589x_of_probe() function and follow the pattern of passing
a platform data pointer back, or an error pointer on error,
as found in the STMPE driver.
- Match the new (proper) compatible strings for the GPIO and
keypad MFD cells.
- Use of_device_is_compatible() rather than just !strcmp()
to discover which cells to instantiate.

It is currently not possible to select the SA1100 or Vexpress

Move the main menu closing and the endif for HAS_IOMEM to the

During probe the sec-core driver allocates dummy I2C device for RTC with
i2c_new_dummy() but return value is not checked. In case of error
(i2c_new_device(): memory allocation failure or I2C address cannot be
used) this function returns NULL which is later used by
devm_regmap_init_i2c() or i2c_unregister_device().
If i2c_new_dummy() fails for RTC device, fail also the probe for main
MFD driver.
