gpio: gpiolib: Generalise state persistence beyond sleep

2018-01-16T17:54:29+00:00

General support for state persistence is added to gpiolib with the introduction of a new pinconf parameter to propagate the request to hardware. The existing persistence support for sleep is adapted to include hardware support if the GPIO driver provides it. Persistence continues to be enabled by default; in-kernel consumers can opt out, but userspace (currently) does not have a choice. The *_SLEEP_MAY_LOSE_VALUE and *_SLEEP_MAINTAIN_VALUE symbols are renamed, dropping the SLEEP prefix to reflect that the concept is no longer sleep-specific. I feel that renaming to just *_MAY_LOSE_VALUE could initially be misinterpreted, so I've further changed the symbols to *_TRANSITORY and *_PERSISTENT to address this. The sysfs interface is modified only to keep consistency with the chardev interface in enforcing persistence for userspace exports.

gpio: core: Decouple open drain/source flag with active low/high

2018-01-16T17:54:29+00:00

Currently, the GPIO interface is said to Open Drain if it is Single Ended and active LOW. Similarly, it is said as Open Source if it is Single Ended and active HIGH. The active HIGH/LOW is used in the interface for setting the pin state to HIGH or LOW when enabling/disabling the interface. In Open Drain interface, pin is set to HIGH by putting pin in high impedance and LOW by driving to the LOW. In Open Source interface, pin is set to HIGH by driving pin to HIGH and set to LOW by putting pin in high impedance. With above, the Open Drain/Source is unrelated to the active LOW/HIGH in interface. There is interface where the enable/disable of interface is ether active LOW or HIGH but it is Open Drain type. Hence decouple the Open Drain with Single Ended + Active LOW and Open Source with Single Ended + Active HIGH. Adding different flag for the Open Drain/Open Source which is valid only when Single ended flag is enabled.

leds: pca955x: add GPIO support

2017-06-16T06:49:04+00:00

The PCA955x family of chips are I2C LED blinkers whose pins not used to control LEDs can be used as general purpose I/Os (GPIOs). The following adds such a support by defining different operation modes for the pins (See bindings documentation for more details). The pca955x driver is then extended with a gpio_chip when some of pins are operating as GPIOs. The default operating mode is to behave as a LED. The GPIO support is conditioned by CONFIG_LEDS_PCA955X_GPIO. OpenBMC-Staging-Count: 1 Signed-off-by: Cédric Le Goater Signed-off-by: Joel Stanley

dt: bindings: net: use boolean dt properties for eee broken modes

2016-12-20T18:50:50+00:00

The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.
