Axel Lin e3a7384c3e regulator: rc5t583: Remove nsteps from struct rc5t583_regulator_info
The nsteps can be calculated by (_max_mv - _min_mv) * 1000 / _step_uV + 1,
thus we can remove _nsteps from RC5T583_REG macro, and then remove
nsteps from struct rc5t583_regulator_info.

Axel Lin a69df8a14a regulator: Fix rc5t583_regulator_probe error handling
1. regulator_register returns ERR_PTR on error, thus use IS_ERR to check the
   return value.
2. Fix off-by-one for unregistering the registered regulator.
   Current code does not unregister regs[0].rdev in clean_exit.

Laxman Dewangan 6ffc327021 regulator: Add support for RICOH PMIC RC5T583 regulator
The RC5T583 PMIC from RICOH consists of 4 DCDC and 10
LDOs. This driver supports the control of different
regulator output through regulator interface.
This driver depends on MFD driver of RC5T583 and uses
mfd rc5t583 apis to communicate to device for accessing
different device's registers.
