Pull char/misc driver updates from Greg KH:
"Here is the large set of char and misc and other driver subsystem
patches for 5.9-rc1. Lots of new driver submissions in here, and
cleanups and features for existing drivers.
Highlights are:
- habanalabs driver updates
- coresight driver updates
- nvmem driver updates
- huge number of "W=1" build warning cleanups from Lee Jones
- dyndbg updates
- virtbox driver fixes and updates
- soundwire driver updates

Support command queue for mt6779 platform.
a. Add msdc_set_busy_timeout() to calculate emmc write timeout.
b. Connect mtk msdc driver to cqhci driver through
host->cq_host->ops = &msdc_cmdq_ops;
c. msdc_cmdq_irq() will link up with cqchi_irq(). Besides, it provides
more irq error messages like RSPCRCERR/CMDTO/DATACRCERR/DATTMO.
d. Select kernel config MMC_CQHCI for MMC_MTK

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver makes use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),
pci_enable_wake() and pci_set_power_state() and to do required operations.
In generic mode, they are no longer needed.
Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use dev_get_drvdata() to get drv data.
Compile-tested only.

As commit ef6b75671b ("mmc: sdhci-cadence: send tune request twice to
work around errata") stated, this IP has an errata. This commit applies
the second workaround for the SD mode.
Due to the errata, it is not possible to use the hardware tuning provided
by SDHCI_HOST_CONTROL2.
Use the software-controlled tuning like the eMMC mode.
Set sdhci_host_ops::platform_execute_tuning instead of overriding
mmc_host_ops::execute_tuning.

cqhci_host_alloc_tdl()'s function header is the only one in
kerneldoc format. Which seems odd as it's not part of an
external API and isn't referenced anywhere else. Seeing as
there has also been no attempt to describe the expected
function arguments either, we're going to assume that this is
not actually a bona fide kerneldoc use-case.
