2020-01-24mfd: Kconfig: Rename Samsung to lowercaseKrzysztof Kozlowski1-1/+1
Fix up inconsistent usage of upper and lowercase letters in "Samsung" name. "SAMSUNG" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

On AXP288 and newer PMICs, bit 7 of AXP20X_VBUS_IPSOUT_MGMT can be set to prevent using the VBUS input. However, when the VBUS unplugged and plugged back in, the bit automatically resets to zero. We need to set the register as volatile to prevent regmap from caching that bit. Otherwise, regcache will think the bit is already set and not write the register.

2020-01-24mfd: ab8500-core: Add device tree support for AB8505Stephan Gerhold2-8/+32
AB8505 support was never fully converted to the device tree. Most of the MFD cells for AB8505 lack an "of_compatible", which prevents them from being configured through the device tree. Align the definition of the AB8505 MFD cells with the ones for AB8500, and add device tree compatibles. Except for GPIO and regulators the compatibles are equal to those used for AB8500 because the hardware does not differ much. Finally, change db8500_prcmu_register_ab8500() to check for the AB8505 device tree node additionally, and probe it if it is found.

2020-01-24gpio: bd71828: Initial support for ROHM BD71828 PMIC GPIOsMatti Vaittinen3-0/+172
ROHM BD71828 PMIC contains 4 pins which can be configured by OTP to be used for general purposes. First 3 can be used as outputs and 4.th pin can be used as input. Allow them to be controlled via GPIO framework. The driver assumes all of the pins are configured as GPIOs and trusts that the reserved pins in other OTP configurations are excluded from control using "gpio-reserved-ranges" device tree property (or left untouched by GPIO users). Typical use for 4.th pin (input) is to use it as HALL sensor input so that this pin state is toggled when HALL sensor detects LID position change (from close to open or open to close). PMIC HW implements some extra logic which allows PMIC to power-up the system when this pin is toggled. Please see the data sheet for details of GPIO options which can be selected by OTP settings.

Few ROHM PMICs allow setting the voltage states for different system states like RUN, IDLE, SUSPEND and LPSR. States are then changed via SoC specific mechanisms. bd718x7 driver implemented device-tree parsing functions for these state specific voltages.

2019-12-07smb3: improve check for when we send the security descriptor context on createSteve French1-0/+2
We had cases in the previous patch where we were sending the security descriptor context on SMB3 open (file create) in cases when we hadn't mounted with with "modefromsid" mount option. Add check for that mount flag before calling ad_sd_context in open init. Signed-off-by: Steve French <[email protected]> Reviewed-by: Pavel Shilovsky <[email protected]>

2019-12-07pipe: don't use 'pipe_wait() for basic pipe IOLinus Torvalds1-3/+27
pipe_wait() may be simple, but since it relies on the pipe lock, it means that we have to do the wakeup while holding the lock. That's unfortunate, because the very first thing the waked entity will want to do is to get the pipe lock for itself. So get rid of the pipe_wait() usage by simply releasing the pipe lock, doing the wakeup (if required) and then using wait_event_interruptible() to wait on the right condition instead. wait_event_interruptible() handles races on its own by comparing the wakeup condition before and after adding itself to the wait queue, so you can use an optimistic unlocked condition for it.
