Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Signed-off-by:

Modify FLASH_EN_SHIFT and TORCH_EN_SHIFT macros to work properly when passed enum max77693_fled values (0 for FLED1 and 1 for FLED2) from leds-max77693 driver. Previous definitions were compatible with one of the previous RFC versions of leds-max77693.c driver, which was not merged. Signed-off-by:

In Quark X1000, there's a single PCI device that provides both an I2C controller and a GPIO controller. This MFD driver will split the 2 devices for their respective drivers. This patch is based on Josef Ahmad's initial work for Quark enabling. Acked-by:

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:

The range of registers used by this driver exceeds that available via SPI with no paging (127), so we have to override the values from the default config which is set-up for I2C access. Also change SPI settings to match device's recommended OTP values. Signed-off-by:

This adds support for the MediaTek MT6397 PMIC. This is a multifunction device with the following sub modules: - Regulator - RTC - Audio codec - GPIO - Clock It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap. MT6397 MFD is a child device of the pwrap. Signed-off-by: Flora Fu, MediaTek Signed-off-by:

To enable/disable ASPM we should find LINK CONTROL register in PCI config space. All old chip use 0x80 address, but new chip may use another address, so we using pci_find_capability() to get LINK CONTROL address. rtsx_gops.c was removed, we consider to put some common operations to this file, but the actual thing is, only a group of chips are in common ops1, and another group of chips in common ops2, it is hard to decide put which ops into generic ops file.

In one shot mode, sequencer automatically disables all enabled steps at the end of each cycle. (both ADC steps and TSC steps) Hence these steps need not be saved in reg_se_cache for clearing these steps at a later stage. Also, when ADC wakes up Sequencer should not be busy executing any of the config steps except for the charge step. Previously charge step was 1 ADC clock cycle and hence it was ignored. TSC steps are always disabled at the end of each conversion cycle, hence there is no need to explicitly disable TSC steps by writing 0 to REG_SE. Signed-off-by:
