Since commit b6f11df26fdc ("trace: Call tracing_reset_online_cpus before
tracer->init()"), get/put_cpu() are not needed anymore.
We can use smp_processor_id() instead.

Notes v3:
- split into smaller, more self-explanatory patches

Separate MMIO (read/write) access into _[read|write]_litex_subregister()

Add BD9574MWF support into bd9571mwv gpio, mfd and regulator drivers.
Latest Ebisu-4D boards has this chip instead of BD9571MWV so that
we need this patch series to detect this chip at runtime.
Note that the patch [1/12] is a bug-fix patch for mfd driver.
Changes from v6:
- Fix typo in the patch
To remove mfd devices when unload this driver, should use
devm_mfd_add_devices() instead.

Thank you for the pointed it out.
I'll fix it.

When multiple VFs do FLR at the same time, the firmware is
processed serially, resulting in some VF FLRs being delayed more
than 100ms, when the virtual machine restarts and the device
driver is loaded, the firmware is doing the corresponding VF
FLR, causing the driver to fail to load.

A BMC register can be configured to disallow this, and if so, causes

Hi Marcel,
Thanks for your suggestions, I will remove the duplicate definitions and
functions.
Firstly, we will add the support of enabling MT7921U in btusb.c
Secondary, we will discuss the driver architecture with you.
Finally, we update the common part and hif part for MT7921.
