2015-07-16drivers: max77693: Move state container to common headerKrzysztof Kozlowski1-25/+0
This prepares for merging some of the drivers between max77693 and max77843 so the child MFD driver can be attached to any parent MFD main driver. Move the state container to common header file. Additionally add consistent 'i2c' prefixes to its members (of 'struct i2c_client' type).

2014-11-10mfd: max77693: Fix always masked MUIC interruptsKrzysztof Kozlowski1-0/+7
All interrupts coming from MUIC were ignored because interrupt source register was masked. The Maxim 77693 has a "interrupt source" - a separate register and interrupts which give information about PMIC block triggering the individual interrupt (charger, topsys, MUIC, flash LED). By default bootloader could initialize this register to "mask all" value. In such case (observed on Trats2 board) MUIC interrupts won't be generated regardless of their mask status. Regmap irq chip was unmasking individual MUIC interrupts but the source was masked Before introducing regmap irq chip this interrupt source was unmasked, read and acked. Reading and acking is not necessary but unmasking is.
