TPS65910: Add tps65910 regulator driver
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>
