2012-06-04mfd: Commonize tps65910 regmap access through headerRhyland Klein
This change removes the read/write callback functions in favor of common regmap accessors inside the header file. This change also makes use of regmap_read/write for single register access which maps better onto what this driver actually needs.

2011-07-22regulator: tps65910: Fix array access out of bounds bugAxel Lin
For tps65910, the number of regulator is 13. ( ARRAY_SIZE(tps65910_regs) is 13) For tps65911, the number of regulator is 12. ( ARRAY_SIZE(tps65911_regs) is 12) If we are using this driver for tps65911, we hit array access out of bounds bug in tps65910_probe() because current implementation always assume the number of regulator is 13 and thus it will access tps65911_regs[12]. Fix it by setting correct num_regulators for both chips in tps65910_probe(), and allocated neccessay memory accordingly.
