| | | | | | | | | | | | | | | | | | | | | | | | | | | | 2bd2d6f2dc ("sched: Replace use of entity_key()") had remove the entity_key() which function is to subtract a tasks vruntime by its groups minvruntime as the rbtree key. The phrase "there is a subtraction using rq->cfs.min_vruntime to account for possible wraparounds" in documentation feels strange and meaningless. So remove it.

The previous "marvell,armada-370-xp-timer" compatible is removed and two new compatible strings are introduced: "marvell,armada-xp-timer" and "marvell,armada-370-timer". The rationale behind this change is that the Armada 370 SoC and the Armada XP SoC timers are not really compatible: * Armada 370 has no 25 MHz fixed timer. * Armada XP cannot work properly without such 25 MHz fixed timer as doing otherwise leads to using a clocksource whose frequency varies when doing cpufreq frequency changes. This commit also removes the "marvell,timer-25Mhz" property, given it's now meaningless.

NOTE: Hardware blinking violates the leds infrastructure driver interface since the hardware only supports blinking all LEDs with the same delay_on/delay_off rates. That is, only the LEDs that are set to blink will actually blink but all LEDs that are set to blink will blink in identical fashion. The delay_on/delay_off values of the last LED that is set to blink will be used for all of the blinking LEDs. If the hardware doesn't support the requested blinking pattern, a default of 500ms on and off will be used. Hardware blinking is disabled by default but can be enabled by setting the 'blink_type' member in the platform_data struct to 'PCA9633_HW_BLINK' or by adding the 'nxp,hw-blink' property to the DTS.

LEDs can be controlled directly via the I2C and programmable engines are supported. LP55xx common driver LP8501 is one of LP55xx family device, so LP55xx common code are used. Chip specific data is defined in the structure, 'lp55xx_device_config'. Differences between LP8501 and LP5523 Different register layout for LED output control and others. LP8501 specific feature for separate output power selection. LP8501 doesn't support external clock detection. Different programming engine data. LP8501 specific feature - output power selection Output channels are selected by power selection - Vout or Vdd. Separate power for VDD1-6 and VDD7-9 are available. It is configurable in the platform data. To support this feature, LP55xx DT structure and header are changed. Device tree binding is updated as well.

Using such a compatible string is not a good idea, since "mvebu" is the name of a large family of SOCs, in which new, unknown SOCs will be coming in the future. It is therefore impossible to know what will be evolutions of this hardware block in the next generations of the SOCs. For this reason, the recommandation for compatible strings of on-SOCs devices has always been to use the name of the oldest SOC that has the hardware block. New SOCs that have an exactly compatible hardware block can reference it using the same compatible string. See [1], [2] and [3] for various cases were this suggestion was made, including from Rob Herring, a Device Tree binding maintainer. As an example, there are already small differences between current generations: * On Kirkwood, only one interrupt is used for audio. * On Dove, two interrupts are used, one for audio data and one for error reporting. In the near future, I'll be adding audio support to Armada 370, which allows has the same hardware block (but maybe with minor variants). Therefore, this patch changes the driver to accept "marvell,kirkwood-audio" and "marvell,dove-audio" as compatible strings instead of the too-generic "marvell,mvebu-audio". The reason for the two different compatible strings is the difference in the number of interrupts used by the two SOCs for audio. This Device Tree binding has never been part of a Linux kernel stable release so far, so it can be changed now without breaking backward compatibility.

The way the binding is performed is also changed so that it uses the new data structure.

This can be done by means of passing a thermal_zone_params.no_hwmon == true. In order to keep same behavior as of today, all current calls will by default create the hwmon interface.

This variable contains the global PID (PID in the init namespace) as %p contains the PID in the current namespace which isn't always what we want. The main use for this is to make it easier to handle crashes that happened within a container. With that new variables it's possible to have the crashes dumped into the container or forwarded to the host with the right PID (from the host's point of view).

The backup battery is optional, connected to the VBACKUP pin, and can be nonrechargeable or rechargeable. The rechargeable battery can be charged from the system supply using the backup battery charger. Add support for enabling charging of this backup battery. Also add the DT binding document and the new properties to have this support.

So to resolve this situation we need to track actions on vma level, there VM_SOFTDIRTY flag comes in. When new vma area created (or old expanded) we set this bit, and keep it here until application calls for clearing soft dirty bit. Thus when user space application track memory changes now it can detect if vma area is renewed.
