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.

2011-07-22regulator: tps65910: Add missing breaks in switch/caseAxel Lin
Also add a default case in tps65910_list_voltage_dcdc to silence 'volt' may be used uninitialized in this function warning. Signed-off-by: Axel Lin <axel.lin@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

2011-05-27regulator: tps65911: Add new chip versionJorge Eduardo Candelaria
The tps65911 chip introduces new features, including changes in the regulator module. - VDD1 and VDD2 remain unchanged. - VDD3 is now named VDDCTRL and has a wider voltage range. - LDOs are now named LDO1...8 and voltage ranges are sequential, making LDOs easier to handle.

2011-05-27regulator: Fix desc_id for tps65023/6507x/65910Axel Lin
The desc_id variable should not be a static variable. The rest of the code assumes the desc_id must less than TPSxxxxx_NUM_REGULATOR. If we set desc_id to be a static variable, checking the return value of rdev_get_id() may return error.

2011-05-27TPS65910: Add tps65910 regulator driverGraeme Gregory
The regulator module consists of 3 DCDCs and 8 LDOs. The output voltages are configurable and are meant to supply power to the main processor and other components Signed-off-by: Graeme Gregory <gg@slimlogic.co.uk> Signed-off-by: Jorge Eduardo Candelaria <jedu@slimlogic.co.uk> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
