	  Say Y here to enable switch capacitor driver.
	  This driver provides a unified interface for switch capacitor.
	  Support device:
	  bq25970
	  ltc7820
	  rt9759

config BQ25970
	bool "bq25970_for_direct_charge"
	depends on SWITCHCAP
	default n
	help
	  Say Y here to enable bq25970 driver.
	  BQ25970 is a 97% efficient, 8-A battery charging solution using a
	  switched cap architecture.
	  This architecture and the integrated FETs are optimized to enable
	  a 50% duty cycle.

config RT9759
	bool "rt9759_for_direct_charge"
	depends on SWITCHCAP
	default n
	help
	  Say Y here to enable rt9759 driver.
	  rt9759 is a high effiency and high charge current charger. The
	  efficiency is up to 97.8% when VBAT = 4.2V, IBAT = 2.5A and the
	  maximum charge current is up to 8A.

config LTC7820
	bool "ltc7820_for_direct_charge"
	depends on SWITCHCAP
	default n
	help
	  Say Y here to enable ltc7820 driver.
	  LTC7820 is a fixed ratio high voltage high power switched capacitor
	  and charge pump controller.
	  This device achieves a 2:1 step-down ratio form an input voltage as
	  high as 72v.

	  bool "sc8545_for_direct_charge"
	  depends on SWITCHCAP
	  default n
	  help
	  Say Y here to enable sc8545 driver.
	  sc8545 is a fixed ratio high voltage high power switched capacitor
	  and low voltage loadswtich ic.

config SM5450
	bool "sm5450_for_direct_charge"
	depends on SWITCHCAP
	default n
	help
	  Say Y here to enable sm5450 driver.
	  sm5450 is a fixed ratio high voltage high power switched capacitor
	  and low voltage loadswtich ic.
