mfd: rk808: Use devm_mfd_add_devices() for mfd_device registration

2016-04-19T06:55:59Z

Use devm_mfd_add_devices() for MFD devices registration and remove the call of mfd_remove_devices() from .remove callback to remove MFD child-devices. This is done by managed device framework. CC: Chris Zhong Signed-off-by: Laxman Dewangan Signed-off-by: Lee Jones

mfd: Constify of_device_id array

2015-03-26T14:20:18Z

of_device_id is always used as const. (See driver.of_match_table and open firmware functions) Signed-off-by: Fabian Frederick Signed-off-by: Lee Jones

mfd: rk808: Disable the under voltage detect

2015-03-12T09:07:10Z

Rk808 has a under voltage detect function, when the voltage of buck is under 85% the target voltage, the buck output will reset. But if the power load is too heavy, this function maybe err, when current over 4.2A, although the voltage is normal, but RK808 mistakenly think it is under 85%, and reset the buck. So let's disable this function. Signed-off-by: Chris Zhong Signed-off-by: Lee Jones

mfd: rk808: Add register caching

2014-09-26T07:23:56Z

Let's define the voltatile registers (those that can't be cached) and enable caching. The rk808 is accessed almost constantly with cpufreq so this is really nice. As measured by ftrace: before this change: cpu0_set_target() => ~2200us after this change: cpu0_set_target() => ~500us Signed-off-by: Doug Anderson Reviewed-by: Chris Zhong Signed-off-by: Lee Jones

mfd: RK808: Add new mfd driver for RK808

2014-09-26T07:15:56Z

The RK808 chip is a power management IC for multimedia and handheld devices. It contains the following components: - Regulators - RTC - Clkout The RK808 core driver is registered as a platform driver and provides communication through I2C with the host device for the different components.
