2024-10-16power: supply: core: mark attribute arrays as ro_after_initThomas Weißschuh
The attribute arrays are only modified during the __init phase. To protect them against intentional or accidental modification, mark them as __ro_after_init. To make sure no modifications are introduced, also mark the return values of the accessors as const.

2024-10-16power: supply: core: unexport power_supply_property_is_writeable()Thomas Weißschuh
Since commit ("power: supply: Drop use_cnt check from power_supply_property_is_writeable()"), this function does not check use_cnt anymore, making it unsuitable for general usage. As it is only used by the psy core anyways, remove it from the public header and unexport it to avoid misusage.

Add a driver for the charger in the TWL6030/32. For now it does not report much in sysfs but parameters are set up for USB, charging is enabled with the specified parameters. It stops charging when full and also restarts charging. This prevents ending up in a system setup where you run out of battery although a charger is plugged in after precharge completed. Battery voltage behavior was checked via the GPADC.

2024-10-15power: supply: core: Remove might_sleep() from power_supply_put()Bart Van Assche
The put_device() call in power_supply_put() may call power_supply_dev_release(). The latter function does not sleep so power_supply_put() doesn't sleep either. Hence, remove the might_sleep() call from power_supply_put().

2024-09-14power: supply: Drop use_cnt check from power_supply_property_is_writeable()Hans de Goede
power_supply_property_is_writeable() gets called from the is_visible() callback for the sysfs attributes of power_supply class devices and for the sysfs attributes of power_supply core instantiated hwmon class devices. These sysfs attributes get registered by the device_add() respectively power_supply_add_hwmon_sysfs() calls in power_supply_register(). use_cnt gets initialized to 0 and is incremented only after these calls. So when power_supply_property_is_writeable() gets called it always return -ENODEV because of use_cnt == 0. This causes all the attributes to have permissions of 444 even those which should be writable. This used to be a problem only for hwmon sysfs attributes but since commit be6299c6e55e ("power: supply: sysfs: use power_supply_property_is_writeable()") this now also impacts power_supply class sysfs attributes.

Changing usb_types type from array to bitmap in the power_supply_desc struct requires updating power-supply drivers living in different subsystem, so it is handled via an immutable branch. Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>
2024-09-03power: supply: Change usb_types from an array into a bitmaskHans de Goede
The bit_types array just hold a list of valid enum power_supply_usb_type values which map to 0 - 9. This can easily be represented as a bitmap. This reduces the size of struct power_supply_desc and further reduces the data section size by drivers no longer needing to store the array. This also unifies how usb_types are handled with charge_behaviours, which allows power_supply_show_usb_type() to be removed.

Move power_supply_show_enum_with_available() higher up in the power_supply_sysfs.c file.

Turn power_supply_charge_behaviour_show() into a generic function for showing enum values with their available (for writing) values shown and the current value shown surrounded by sqaure-brackets like the show() output for "usb_type" and "charge_behaviour". This is a preparation patch for refactoring the "usb_type" property handling to use a bitmask indicating available usb-types + this new generic function.

2024-09-03power: supply: rt9467-charger: Remove "usb_type" property write supportHans de Goede
The "usb_type" property must be read-only for charger power-supply devices, see: Documentation/ABI/testing/sysfs-class-power. But the rt9467 driver allows writing 0/1 to it to disable/enable charging. Other charger drivers use the "status" property for this and the rt9467 code also allows writing 0/1 to its "status" property and this does the exact same thing as writing 0/1 to its "usb_type" property. Drop write support for the "usb_type" property making it readonly to match the ABI documentation. If userspace wants to disable/enable charging it can use the "status" property for this.

2024-09-03power: supply: ucs1002: Adjust ucs1002_set_usb_type() to accept string valuesHans de Goede
power_supply_sysfs.c accept wrrites of strings to "usb_type" for strings values matching an entry in POWER_SUPPLY_USB_TYPE_TEXT[]. If such a string value is written then the int value passed to ucs1002_set_property() will be an enum power_supply_usb_type value. Before this change ucs1002_set_usb_type() expected the value to be an index into ucs1002_usb_types[]. Adjust ucs1002_set_usb_type() to use the enum value directly so that writing string values works. The list of supported types in ucs1002_usb_types[] is: PD, SDP, DCP, CDP. The [POWER_SUPPLY_USB_TYPE_]SDP, DCP and CDP enum labels have a value of 1, 2 and 3. So userspace selecting SDP, DCP or CDP by writing 1, 2 or 3 will keep working. POWER_SUPPLY_USB_TYPE_PD which is mapped to the ucs1002 dedicated mode however has a value of 6. Before this change writing 0 would select the dedicated mode. To preserve userspace API compatibility also map POWER_SUPPLY_USB_TYPE_UNKNOWN (which is 0) to the dedicated mode.

2024-09-03power: supply: "usb_type" property may be written toHans de Goede
According to Documentation/ABI/testing/sysfs-class-power the "usb_type" property is Read-Only. For power-supplies which consume USB power such as battery charger chips, this is correct. But the UCS1002 USB Port Power Controller driver which is a driver for a chip which is a power-source for USB-A charging ports "usb_type" is actually writable to configure the type of USB charger emulated by the USB-A port. Adjust the docs and the power_supply_sysfs.c code to adjust for this new writeable use of "usb_type": 1. Update Documentation/ABI/testing/sysfs-class-power to document that "usb_type" may be writable 2. Change the power_supply_attr type in power_supply_sysfs.c from POWER_SUPPLY_ATTR() into POWER_SUPPLY_ENUM_ATTR() so that the various usb_type string values from POWER_SUPPLY_TYPE_TEXT[] such as e.g. "SDP" and "USB_PD" can be written to the "usb_type" attribute instead of only accepting integer values.

SDM670 is excluded from tzmem usage due to reported issues. The SCM get wait queue context call is corrected to be marked ATOMIC and some dead code in qseecom, following the tzmem conversion, is removed. The memory backing command DB is remapped writecombined, to avoid XPU violations when Linux runs without the Qualcomm hypervisor. Two compile fixes are added for pd-mapper, and the broken reference count is corrected, to make pd-mapper deal with remoteprocs going away. In pmic_glink a race condition where the client callbacks might be called before we returned the client handle is corrected. The broken conditions for when to signal that the firmware is going down is also corrected. In the pmic_glink UCSI driver, the ucsi_unregister() is moved out of the pdr callback, as this is being invoked in atomic context.
