mfd: tps65086: Add cell entry for reset driver

2021-08-26T21:07:32+00:00

The only way to reset the BeagleV Starlight v0.9 board[1] properly is to tell the PMIC to reset itself which will then assert the external reset lines of the SoC, USB hub and ethernet phy. This adds an mfd cell entry for the reset driver doing just that. [1] https://github.com/beagleboard/beaglev-starlight Signed-off-by: Emil Renner Berthing

mfd: tps65086: Make interrupt line optional

2021-08-26T21:07:32+00:00

The BeagleV Starlight v0.9 board[1] doesn't have the IRQB line routed to the SoC, but it is still useful to be able to reach the PMIC over I2C for the other functionality it provides such as GPIOs and regulator settings.

mfd: cpcap: Fix cpcap dmamask not set warnings

2021-07-20T14:00:16+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.

[ Upstream commit 4700ef326556ed74aba188f12396740a8c1c21dd ] This patch adds/modifies MODULE_DEVICE_TABLE definition which generates correct modalias for automatic loading of this driver when it is built as an external module.

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

2021-07-19T08:04:51+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

2021-07-14T15:07:34+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.

mfd: Remove software node conditionally and locate at right place

2021-07-14T15:07:34+00:00

[ Upstream commit 5a23e8b0fd6010e25ae58362292235cc9213ca57 ] Currently the software node is removed in error case and at ->remove() stage unconditionally, that ruins the symmetry. Besides, in some cases, when mfd_add_device() fails, the device_remove_software_node() call may lead to NULL pointer dereference: BUG: kernel NULL pointer dereference, address: 00000000 ... EIP: strlen+0x12/0x20 ... kernfs_name_hash+0x13/0x70 kernfs_find_ns+0x32/0xc0 kernfs_remove_by_name_ns+0x2a/0x90 sysfs_remove_link+0x16/0x30 software_node_notify.cold+0x34/0x6b device_remove_software_node+0x5a/0x90 mfd_add_device.cold+0x30a/0x427 Fix all these by guarding device_remove_software_node() with a conditional and locating it at the right place.
