2023-02-22mfd: arizona: Use pm_runtime_resume_and_get() to prevent refcnt leakLiang He
In arizona_clk32k_enable(), we should use pm_runtime_resume_and_get() as pm_runtime_get_sync() will increase the refcnt even when it returns an error.

2023-02-22mfd: syscon: Allow reset control for syscon devicesJeremy Kerr
Simple syscon devices may require deassertion of a reset signal in order to access their register set. Rather than requiring a custom driver to implement this, we can use the generic "resets" specifiers to link a reset line to the syscon. This change adds an optional reset line to the syscon device description, and deasserts the reset if detected.

2023-02-22dt-bindings: mfd/syscon: Add resets propertyJeremy Kerr
Simple syscon devices may require deassertion of a reset signal in order to access their register set. This change adds the `resets` property from reset.yaml#/properties/resets (referenced through core.yaml), specifying a maxItems of 1 for a single (optional) reset descriptor. This will allow a future change to the syscon driver to implement reset control.

2023-02-22mfd: axp20x: Switch to the sys-off handler APISamuel Holland
This removes a layer of indirection through pm_power_off() and allows the PMIC handler to be used as a fallback when firmware power off fails. This happens on boards like the Clockwork DevTerm R-01 where OpenSBI does not know how to use the PMIC to power off the board. Move the check for AXP288 to avoid registering a dummy handler.

2023-02-22mfd: twl: Fix TWL6032 phy vbus detectionAndreas Kemnade
TWL6032 has a few charging registers prepended before the charging registers the TWL6030 has. To be able to use common register defines declare the additional registers as additional module. At the moment this affects the access to CHARGERUSB_CTRL1 in phy-twl6030-usb. Without this patch, it is accessing the wrong register on TWL6032. The consequence is that presence of Vbus is not reported.

2023-02-22mfd: axp20x: Fix order of pek rise and fall eventsAren Moynihan
The power button can get "stuck" if the rising edge and falling edge irq are read in the same pass. This can often be triggered when resuming from suspend if the power button is released before the kernel handles the interrupt. Swapping the order of the rise and fall events makes sure that the press event is handled first, which prevents this situation.

2023-01-30fpga: m10bmc-sec: Add support for N6000Ilpo Järvinen
Add support for PMCI-based flash access path and N6000 sec update support. Access to flash staging area is different for N6000 from that of the SPI interfaced counterparts. Introduce intel_m10bmc_flash_bulk_ops to allow interface specific differentiations for the flash access path for sec update and make m10bmc_sec_read/write() in sec update driver to use the new operations. The .flash_mutex serializes read/read. Flash update (erase+write) must use ->lock/unlock_write() to prevent reads during update (reads would timeout on setting flash MUX as BMC will prevent it). Create a type specific RSU status reg handler for N6000 because the field has moved from doorbell to auth result register. If a failure is detected while altering the flash MUX, it seems safer to try to set it back and doesn't seem harmful. Likely there are enough troubles in that case anyway so setting it back fails too (which is harmless sans the small extra delay) or just confirms that the value wasn't changed.

Store type specific info into struct and place them into .driver_data instead because it makes things a bit cleaner. The m10bmc_type enum can be dropped as the differentiation is now fully handled by the platform info. The info member of struct intel_m10bmc that is added here is not used yet in this change but its addition logically still belongs to this change. The CSR map change that comes after this change needs to have the info member.

2022-12-25treewide: Convert del_timer*() to timer_shutdown*()Steven Rostedt (Google)
Due to several bugs caused by timers being re-armed after they are shutdown and just before they are freed, a new state of timers was added called "shutdown". After a timer is set to this state, then it can no longer be re-armed. The following script was run to find all the trivial locations where del_timer() or del_timer_sync() is called in the same function that the object holding the timer is freed. It also ignores any locations where the timer->function is modified between the del_timer*() and the free(), as that is not considered a "trivial" case. This was created by using a coccinelle script and the following commands: $ cat timer.cocci @@ expression ptr, slab; identifier timer, rfield; @@ ( - del_timer(&ptr->timer); + timer_shutdown(&ptr->timer); | - del_timer_sync(&ptr->timer); + timer_shutdown_sync(&ptr->timer); ) ... when strict when != ptr->timer ( kfree_rcu(ptr, rfield); | kmem_cache_free(slab, ptr); | kfree(ptr); ) $ spatch timer.cocci . > /tmp/t.patch $ patch -p1 < /tmp/t.patch Link: https://lore.kernel.org/lkml/20221123201306.823305113@linutronix.de/ Signed-off-by: Steven Rostedt (Google) <rostedt@goodmis.org> Acked-by: Pavel Machek <pavel@ucw.cz> [ LED ] Acked-by: Kalle Valo <kvalo@kernel.org> [ wireless ] Acked-by: Paolo Abeni <pabeni@redhat.com> [ networking ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2022-12-23pstore: Properly assign mem_type propertyLuca Stefani
If mem-type is specified in the device tree it would end up overriding the record_size field instead of populating mem_type. As record_size is currently parsed after the improper assignment with default size 0 it continued to work as expected regardless of the value found in the device tree. Simply changing the target field of the struct is enough to get mem-type working as expected.
