"rm -rf" is bricking some peoples' laptops because of variables being used to store non-reinitializable firmware driver data that's required to POST the hardware. These are 100% bugs, and they need to be fixed, but in the mean time it shouldn't be easy to *accidentally* brick machines. We have to have delete working, and picking which variables do and don't work for deletion is quite intractable, so instead make everything immutable by default (except for a whitelist), and make tools that aren't quite so broad-spectrum unset the immutable flag.

It may be useful to debug writes to the readonly sections of memory, so provide a cmdline "rodata=off" to allow for this. This can be expanded in the future to support "log" and "write" modes, but that will need to be architecture-specific. This also makes KDB software breakpoints more usable, as read-only mappings can now be disabled on any kernel. Suggested-by: H.

* | | | regulator: rpm-smd-regulator: implement set_loadNicholas Troast2016-06-28

The regulator_set_load API does the following for regulators which have not implemented set_load(). - determines the most optimal mode for the given load by calling get_optimum_mode() - gets the current mode by calling get_mode() - calls set_mode() if the modes are different and expects the mode to be committed to the hardware The rpm-smd-regulator's get_optimum_mode() remembers the load and uses that for the upcoming get_mode() call. This causes the framework to never call the set_mode API, thereby causing rpm-smd-regulator to never send the load to the RPM. The set_load op was introduced for hardware which does not support the set_mode op. This is convenient since the RPM sets the mode according to the aggregated load requirements. In addition the RPM also supports forcing certain modes which fits well with the set_mode op. Implement the set_load op to send the aggregated load vote to RPM, and repurpose the set_mode op to send the aggregated mode vote to RPM. Remove the get_optimum_mode op since it is no longer required with this change. Repurposing of set_mode should not impact consumers since it has the same effect as before. Instead of sending a load vote which would cause the RPM to select the desired mode the mode will be sent directly. Furthermore, the hpm-min-load device tree property is no longer required since the mode is no longer set based on the hpm-min-load threshold. Remove it.

The values of this data item is defined in the document Document/arm/msm/boot.txt, the following is the data in the documentation file. power_on_status values set by the PMIC for power on event: ---------------------------------------------------------- 0x01 -- keyboard power on 0x02 -- RTC alarm 0x04 -- cable power on 0x08 -- SMPL 0x10 -- Watch Dog timeout 0x20 -- USB charger 0x40 -- Wall charger 0xFF -- error reading power_on_status value This is cherrypicked from commit <372d39f87b0da75> ("put reason for boot in procfs") of 3.18 tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with DSI PHY hardware revisions 3.0 and above, data lane swap configurations need to be programmed via the DSI PHY interface. In other cases, a new register interface has been introduced to program the lane swap configuration for DSI controller revision 2.0 and above. Refactor the existing implementation to account for these hardware changes. Change-Id: I3772c614bfee0ed13f30a38535bb814158d23226 Signed-off-by: Aravind Venkateswaran <aravindh@codeaurora.org>
* | | | regulator: qpnp-labibb: Add support for controlling IBB pulse skip timingAnirudh Ghayal2016-06-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IBB pulse-skip and NLIMIT DAC configuration should be disabled before applying the 2nd SWIRE command skip logic, to guarantee that the IBB voltage changes immediately in the subsequent SWIRE command. After the WA is completed, the pulse-skip can be re-enabled after a programmable delay. Add this logic and a DT property 'qcom,swire-ibb-ps-enable-delay' to configure this delay. If this delay is not specified in the DT it defaults to 200ms. CRs-Fixed: 1010085 Change-Id: Ifec458a0028c16440ffd6ac1f6fa58eebc815c5a Signed-off-by: Anirudh Ghayal <aghayal@codeaurora.org>

This charger peripheral is common among other chips, therefore the driver uses the smb library to support all common functionality. Register access is provided by the parent device via regmap. Interrupts are controlled by the parent device, and handlers are registered by the SMB138X charger driver. The power supply framework is used to communicate battery and usb properties to userspace and other driver consumers such as fuel gauge and USB. VBUS and VCONN regulators are registered for supporting OTG, and powered Type-C cables respectively.

The controller enumerates all child nodes as platform devices, and instantiates a regmap interface for them to communicate over the I2C bus. The controller also controls interrupts for all of the children platform devices. The controller handles the summary interrupt by deciphering which peripheral triggered the interrupt, and which of the peripheral interrupts were triggered. Finally, it calls the interrupt handlers for each of the virtual interrupts that were registered.
