mfd: intel-peci-client: Extend MFD cell id with additional parameter

2021-08-02T16:04:00+00:00

If we're only using CPU number as MFD cell id, we don't have a way to avoid a collision in case we have multiple adapters able to communicate with the same CPUs. [ 794.916872] sysfs: cannot create duplicate filename '/bus/platform/devices/peci-cputemp.0' [ 795.452507] intel_peci_client 1-30: Failed to register child devices: -17 [ 795.460238] intel_peci_client: probe of 1-30 failed with error -17 To fix this problem, let's use both adapter number and cpu number to calculate MFD cell id.

hwmon: peci: dimmpower implementation

2021-08-02T16:04:00+00:00

1. Peci dimmpower module implementation. 2. Enable DIMM avarage power, power limit, power limit max setting, power limit min setting reading and expose them under power1_avarage, power1_cap, power1_cap_max, power1_cap_min in sysfs. 3. Enable DIMM power limit writing through power1_cap. Tested: * on WilsonCity platform, * power1_avarage, power1_cap, power1_cap_max and power1_cap_min work as expected Signed-off-by: Zbigniew Lukwinski

mfd: cpcap: Fix cpcap dmamask not set warnings

2021-07-20T14:05:42+00:00

[ Upstream commit 0b7cbe811ca524295ea43d9a4d73d3427e419c54 ] We have started to get a bunch of pointless dmamask not set warnings that makes the output of dmesg -l err,warn hard to read with many extra warnings: cpcap-regulator cpcap-regulator.0: DMA mask not set cpcap_adc cpcap_adc.0: DMA mask not set cpcap_battery cpcap_battery.0: DMA mask not set cpcap-charger cpcap-charger.0: DMA mask not set cpcap-pwrbutton cpcap-pwrbutton.0: DMA mask not set cpcap-led cpcap-led.0: DMA mask not set cpcap-led cpcap-led.1: DMA mask not set cpcap-led cpcap-led.2: DMA mask not set cpcap-led cpcap-led.3: DMA mask not set cpcap-led cpcap-led.4: DMA mask not set cpcap-rtc cpcap-rtc.0: DMA mask not set cpcap-usb-phy cpcap-usb-phy.0: DMA mask not set This seems to have started with commit 4d8bde883bfb ("OF: Don't set default coherent DMA mask"). We have the parent SPI controller use DMA, while CPCAP driver and it's children do not. For audio, the DMA is handled over I2S bus with the McBSP driver.

mfd: syscon: Free the allocated name field of struct regmap_config

2021-07-19T07:45:00+00:00

commit 56a1188159cb2b87fbcb5a7a7afb38a4dd9db0c1 upstream. The commit 529a1101212a("mfd: syscon: Don't free allocated name for regmap_config") doesn't free the allocated name field of struct regmap_config, but introduce a memory leak. There is another commit 94cc89eb8fa5("regmap: debugfs: Fix handling of name string for debugfs init delays") fixing this debugfs init issue from root cause. With this fixing, the name field in struct regmap_debugfs_node is removed. When initialize debugfs for syscon driver, the name field of struct regmap_config is not used anymore. So, the allocated name field of struct regmap_config is need to be freed directly after regmap initialization to avoid memory leak.

mfd: rn5t618: Fix IRQ trigger by changing it to level mode

2021-07-14T14:56:40+00:00

[ Upstream commit a1649a5260631979c68e5b2012f60f90300e646f ] During more massive generation of interrupts, the IRQ got stuck, and the subdevices did not see any new interrupts. That happens especially at wonky USB supply in combination with ADC reads. To fix that trigger the IRQ at level low instead of falling edge.
