peci: Extend peci client with Domain ID information

2022-05-23T12:06:36+00:00

Since PECI Target addressing has been changed to use Domain ID information, each peci_client instance should correspond with both CPU ID and Domain ID. Let's extend peci_client structure, sysfs API and intel-peci-client to use Domain ID. Make MFD device ID as a combination of peci adapter number, CPU ID and Domain ID. Signed-off-by: Iwona Winiarska

[ Upstream commit e477e51a41cb5d6034f3c5ea85a71ad4613996b9 ] As the potential failure of the devm_request_threaded_irq(), it should be better to check the return value of the mc13xxx_irq_request() and return error if fails.

mfd: tps65910: Set PWR_OFF bit during driver probe

2022-01-27T10:05:07+00:00

commit 7620ad0bdfac1efff4a1228cd36ae62a9d8206b0 upstream. The PWR_OFF bit needs to be set in order to power off properly, without hanging PMIC. This bit needs to be set early in order to allow thermal protection of NVIDIA Terga SoCs to power off hardware properly, otherwise a battery re-plug may be needed on some devices to recover after the hang.

mfd: atmel-flexcom: Use .resume_noirq

2022-01-27T10:03:18+00:00

[ Upstream commit 5d051cf94fd5834a1513aa77e542c49fd973988a ] Flexcom IP embeds 3 other IPs: usart, i2c, spi and selects the operation mode (usart, i2c, spi) via mode register (FLEX_MR). On i2c bus there might be connected critical devices (like PMIC) which on suspend/resume should be suspended/resumed at the end/beginning. i2c uses .suspend_noirq/.resume_noirq for this kind of purposes. Align flexcom to use .resume_noirq as it should be resumed before the embedded IPs. Otherwise the embedded devices might behave badly.

mfd: intel-lpss: Fix too early PM enablement in the ACPI ->probe()

2022-01-16T08:12:44+00:00

commit c9e143084d1a602f829115612e1ec79df3727c8b upstream. The runtime PM callback may be called as soon as the runtime PM facility is enabled and activated. It means that ->suspend() may be called before we finish probing the device in the ACPI case. Hence, NULL pointer dereference: intel-lpss INT34BA:00: IRQ index 0 not found BUG: kernel NULL pointer dereference, address: 0000000000000030 ... Workqueue: pm pm_runtime_work RIP: 0010:intel_lpss_suspend+0xb/0x40 [intel_lpss] To fix this, first try to register the device and only after that enable runtime PM facility.

mfd: syscon: Use regmap with raw_spinlock for ast2x00-scu

2021-12-15T11:57:09+00:00

The irq-aspeed-scu-ic driver uses syscon regmap inside its irq_chip implementation. Some of the functions are called by IRQ core under raw_spinlock, since the regmap config is controlled by the generic syscon driver, in order to silence the warning: [ 0.687661] [ BUG: Invalid wait context ] we need to make sure that the regmap is configured in a mode that uses raw_spinlock. NOTE: It is just a workaround - it will not be upstreamed, proper fix would require either adding a new syscon DTS property, or converting the irq-aspeed-scu-ic driver to not use generic syscon.
