2023-01-27mei: mei-me: resume device in prepareAlexander Usyskin
Asynchronous runtime resume is not possible while the system is suspending. The power management subsystem resumes the device only in the suspend phase, not in the prepare phase. Force resume device in prepare to allow drivers on mei bus to communicate in their prepare callbacks.

Use dma_set_mask_and_coherent() instead of unrolling it with some dma_set_mask()+dma_set_coherent_mask(). Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never fail if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. Simplify code and remove some dead code accordingly. While at it, include directly <linux/dma-mapping.h> instead on relying on indirect inclusion.

2020-07-29mei: add device kind to sysfsAlexander Usyskin
Some of the mei device heads are not generic and have a specific purpose, we need to announce it to the user space so it is possible to detect the correct device node via matching attributes. Generic heads are marked as 'mei' while special purpose heads have their own names. Currently we are adding 'itouch' string for Intel IPTS 1.0, 2.0 devices. This is done via new sysfs attribute 'kind'.

2020-04-20mei: me: fix irq number stored in hw structBenjamin Lee
Commit 261b3e1f2a01 ("mei: me: store irq number in the hw struct.") stores the irq number in the hw struct before MSI is enabled. This caused a regression for mei_me_synchronize_irq() waiting for the wrong irq number. On my laptop this causes a hang on shutdown. Fix the issue by storing the irq number after enabling MSI.

2018-01-02mei: me: allow runtime pm for platform with D0i3Tomas Winkler
>From the pci power documentation: "The driver itself should not call pm_runtime_allow(), though. Instead, it should let user space or some platform-specific code do that (user space can do it via sysfs as stated above)..." However, the S0ix residency cannot be reached without MEI device getting into low power state. Hence, for mei devices that support D0i3, it's better to make runtime power management mandatory and not rely on the system integration such as udev rules. This policy cannot be applied globally as some older platforms were found to have broken power management. Cc: <stable@vger.kernel.org> v4.13+ Cc: Rafael J.

* pm-core: ACPI / PM: Take SMART_SUSPEND driver flag into account PCI / PM: Take SMART_SUSPEND driver flag into account PCI / PM: Drop unnecessary invocations of pcibios_pm_ops callbacks PM / core: Add SMART_SUSPEND driver flag PCI / PM: Use the NEVER_SKIP driver flag PM / core: Add NEVER_SKIP and SMART_PREPARE driver flags PM / core: Convert timers to use timer_setup() PM / core: Fix kerneldoc comments of four functions PM / core: Drop legacy class suspend/resume operations
2017-11-06PCI / PM: Use the NEVER_SKIP driver flagRafael J. Wysocki
Replace the PCI-specific flag PCI_DEV_FLAGS_NEEDS_RESUME with the PM core's DPM_FLAG_NEVER_SKIP one everywhere and drop it. Signed-off-by: Rafael J.
