2021-10-12power: supply: max17042_battery: Clear status bits in interrupt handlerSebastian Krzyszkowiak1-0/+4
The gauge requires us to clear the status bits manually for some alerts to be properly dismissed. Previously the IRQ was configured to react only on falling edge, which wasn't technically correct (the ALRT line is active low), but it had a happy side-effect of preventing interrupt storms on uncleared alerts from happening.

2021-10-12power: supply: axp288-charger: Optimize register reading methodKate Hsuan1-51/+99
The original implementation access the charger the same register value several times to get the charger status, such as online, enabled, and bus limits. It takes a long time and bandwidth for every "status get" operation.  To reduce the access of the register and save bandwidth, this commit integrated every read operation into only one "register value get"  operation and cache them in the variables. Once the "get properties" is requested from the user space, the cached information can be returned immediately. I2C access between Linux kernel and P-Unit is improved by explicitly taking semaphore once for the entire set of register accesses in the new axp288_charger_usb_update_property() function. The I2C-Bus to the XPower AXP288 is shared between the Linux kernel and SoCs P-Unit. The P-Unit has a semaphore which the kernel must "lock" before it may use the bus. If not explicitly taken by the I2C-Driver, then this semaphore is automatically taken by the I2C-bus-driver for each I2C-transfer. In other words, the semaphore will be locked and released several times for entire set of register accesses.

2021-10-02power: supply: max17042_battery: use VFSOC for capacity when no rsnsHenrik Grimler1-1/+4
On Galaxy S3 (i9300/i9305), which has the max17047 fuel gauge and no current sense resistor (rsns), the RepSOC register does not provide an accurate state of charge value. The reported value is wrong, and does not change over time. VFSOC however, which uses the voltage fuel gauge to determine the state of charge, always shows an accurate value. For devices without current sense, VFSOC is already used for the soc-alert (0x0003 is written to MiscCFG register), so with this change the source of the alert and the PROP_CAPACITY value match.

2021-09-11perf tools: Allow build-id with trailing zerosNamhyung Kim1-0/+10
Currently perf saves a build-id with size but old versions assumes the size of 20. In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf. The build-id event in the data has 20 byte build-ids, but it saw a different size (16) when it reads the build-id of the elf file in the build-id cache. $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf Displaying notes found in: .note.gnu.build-id Owner Data size Description GNU 0x00000010 NT_GNU_BUILD_ID (unique build ID bitstring) Build ID: 53e4c2f42a4c61a2d632d92a72afa08f Let's fix this by allowing trailing zeros if the size is different.

2021-09-11perf tools: Fix hybrid config terms list corruptionAdrian Hunter2-9/+27
A config terms list was spliced twice, resulting in a never-ending loop when the list was traversed. Fix by using list_splice_init() and copying and freeing the lists as necessary.
