2020-12-26mfd: ab8500-debugfs: Remove extraneous seq_putcLinus Torvalds
Commit c9a3c4e637ac ("mfd: ab8500-debugfs: Remove extraneous curly brace") removed a left-over curly brace that caused build failures, but Joe Perches points out that the subsequent 'seq_putc()' should also be removed, because the commit that caused all these problems already added the final '\n' to the seq_printf() above it.

2020-12-15mfd: ab8500-debugfs: Remove the racy fiddling with irq_descThomas Gleixner
First of all drivers have absolutely no business to dig into the internals of an irq descriptor. That's core code and subject to change. All of this information is readily available to /proc/interrupts in a safe and race free way. Remove the inspection code which is a blatant violation of subsystem boundaries and racy against concurrent modifications of the interrupt descriptor. Print the irq line instead so the information can be looked up in a sane way in /proc/interrupts.

2020-12-02mfd: kempld-core: Add support for additional devicesMichael Brunner
This update includes DMI IDs for the following Kontron modules and systems: COMe-bDV7, COMe-cDV7, COMe-m4AL, COMe-mCT10, SMARC-sXAL, SMARC-sXA4, Qseven-Q7AL, mITX-APL, pITX-APL and KBox A-203 Furthermore the ACPI HID KEM0000 is added, as it is also reserved for kempld devices. Instead of also adding the newly supported devices to the Kconfig description this patch removes the lengthy list. With future usage of the ACPI HIDs it will not be necessary to explicitly add support for each individual device to the driver and therefore the list would become incomplete anyway.

2020-11-19rtc: rework rtc_register_device() resource managementBartosz Golaszewski
rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.

2020-11-19mfd: cpcap: Fix interrupt regression with regmap clear_ackTony Lindgren
With commit 3a6f0fb7b8eb ("regmap: irq: Add support to clear ack registers"), the cpcap interrupts are no longer getting acked properly leading to a very unresponsive device with CPUs fully loaded spinning in the threaded IRQ handlers. To me it looks like the clear_ack commit above actually fixed a long standing bug in regmap_irq_thread() where we unconditionally acked the interrupts earlier without considering ack_invert. And the issue with cpcap started happening as we now also consider ack_invert. Tim Harvey <tharvey@gateworks.com> tried to fix this issue earlier with "[PATCH v2] regmap: irq: fix ack-invert", but the reading of the ack register was considered unnecessary for just ack_invert, and we did not have clear_ack available yet. As the cpcap irqs worked both with and without ack_invert earlier because of the unconditional ack, the problem remained hidden until now. Also, looks like the earlier v3.0.8 based Motorola Android Linux kernel does clear_ack style read-clear-write with "ireg_val & ~mreg_val" instead of just ack_invert style write. So let's switch cpcap to use clear_ack to fix the issue.

2020-11-19mfd: madera: Add special errata reset handling for cs47l15Charles Keepax
An errata exists for cs47l15 where the reset must be handled differently and removed before DCVDD is applied. A soft reset is used for situations where a reset is required to reset state. This does however, make this part unsuitable for DCVDD supplies with a rise time greater than 2mS.

2020-11-19mfd: madera: Add reset as part of resumeCharles Keepax
The DCVDD supply does not always power down when the CODEC enters suspend, for example shared regulators or always-on regulators. In these cases if a register is written back to the default value whilst the CODEC is in suspend that register will retain the previous value. As DCVDD never powered down, the register retains its old value and as the cache sync only synchronises registers that differ from the default the new value is never written out. Ensure the registers are in the expected state after suspend by always resetting the CODEC on resume. This also has the benefit of being recommended by the datasheet for DCVDD supplies that take longer than 2mS to rise.

2020-11-19mfd: syscon: Add syscon_regmap_lookup_by_phandle_optional() function.Enric Balletbo i Serra
This adds syscon_regmap_lookup_by_phandle_optional() function to get an optional regmap. It behaves the same as syscon_regmap_lookup_by_phandle() except where there is no regmap phandle. In this case, instead of returning -ENODEV, the function returns NULL. This makes error checking simpler when the regmap phandle is optional.

2020-11-04mfd: Intel Platform Monitoring Technology supportDavid E. Box
Intel Platform Monitoring Technology (PMT) is an architecture for enumerating and accessing hardware monitoring facilities. PMT supports multiple types of monitoring capabilities. This driver creates platform devices for each type so that they may be managed by capability specific drivers (to be introduced). Capabilities are discovered using PCIe DVSEC ids. Support is included for the 3 current capability types, Telemetry, Watcher, and Crashlog. The features are available on new Intel platforms starting from Tiger Lake for which support is added. This patch adds support for Tiger Lake (TGL), Alder Lake (ADL), and Out-of-Band Management Services Module (OOBMSM). Also add a quirk mechanism for several early hardware differences and bugs. For Tiger Lake and Alder Lake, do not support Watcher and Crashlog capabilities since they will not be compatible with future product. Also, fix use a quirk to fix the discovery table offset.
