GCE hardware stored event information in own internal sysram,
if the initial value in those sysram is not zero value
it will cause a situation that gce can wait the event immediately
after client ask gce to wait event but not really trigger the
corresponding hardware.
In order to make sure that the wait event function is
exactly correct, we need to clear the sysram value in
cmdq initial flow.

Pull driver core and debugfs updates from Greg KH:
"Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse easier
due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes

Previously, if mbox_request_channel_byname was used with a name
which did not exist in the "mbox-names" property of a mailbox
client, the mailbox corresponding to the last entry in the
"mbox-names" list would be incorrectly selected.
With this patch, -EINVAL is returned if the named mailbox is
not found.

The TI K3 AM65x and J721E family of SoCs have a new Mailbox IP that
is based on the existing Mailbox IP present in OMAP architecture based
SoCs. Each instance of the legacy OMAP Mailbox IP is now a single cluster
within the newer Mailbox IP instance on K3 architecture based SoCs. A
single K3 Mailbox IP instance has multiple clusters with each cluster
providing the same functionality as the existing OMAP Mailbox IP.
Reuse the existing OMAP Mailbox driver to extend the support for this
newer IP present within the Main NavSS block on K3 SoCs. The K3 family
of SoCs use 64-bit ARMv8 processors for running Linux, so the driver is
also enhanced to deal with the differences between the 32-bit message
payloads and the 64-bit pointers used by the client drivers.

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

Pull mailbox updates from Jassi Brar:
- New driver: Armada 37xx mailbox controller
- Misc: Use devm_ api for imx and platform_get_irq for stm32
* tag 'mailbox-v5.2' of git://git.linaro.org/landing-teams/working/fujitsu/integration:
mailbox: Add support for Armada 37xx rWTM mailbox
dt-bindings: mailbox: Document armada-3700-rwtm-mailbox binding
mailbox: stm32-ipcc: check invalid irq
mailbox: imx: use devm_platform_ioremap_resource() to simplify code
|
|
This adds support for the mailbox via which the kernel can communicate
with the firmware running on the secure processor of the Armada 37xx
SOC.
The rWTM secure processor has access to internal eFuses and
cryptographic circuits, such as the Entropy Bit Generator to generate
true random numbers.

On failure of_irq_get() returns a negative value or zero, which is
not handled as an error in the existing implementation.
Instead of using this API, use platform_get_irq() that returns
exclusively a negative value on failure.
Also, do not output an error log in case of defer probe error.

Parsing entries in an ACPI table had assumed a generic header
structure. There is no standard ACPI header, though, so less common
layouts with different field sizes required custom parsers to go through
their subtable entry list.
Create the infrastructure for adding different table types so parsing
the entries array may be more reused for all ACPI system tables and
the common code doesn't need to be duplicated.

During noirq suspend phase, mailbox MU irq will be masked
but many drivers still need to communicate with system
controller firmware via mailbox, if MU irq is masked, it
will cause RPC timeout as below:
[ 23.372103] imx-scu scu: RPC send msg timeout
Setting MU irq to be wakeup source is NOT working as GIC
driver does NOT have .irq_set_wake implemented, so to
support suspend/resume, just make imx mailbox driver NOT
suspend, since MU is always a wakeup source on i.MX platforms
with system controller inside, and its power/clock is
maintained by system controller, mailbox driver no need
to manage them.

Use devm_kstrdup_const() in the tegra-hsp driver. This mostly serves as
an example of how to use this new routine to shrink driver code.
Also use devm_kzalloc() instead of regular kzalloc() to shrink the
driver even more.
Doorbell objects are only removed in the driver's remove callback so
it's safe to convert all memory allocations to devres.

The Tegra HSP block supports 'shared mailboxes' that are simple 32-bit
registers consisting of a FULL bit in MSB position and 31 bits of data.
The hardware can be configured to trigger interrupts when a mailbox
is empty or full. Add support for these shared mailboxes to the HSP
driver.
The initial use for the mailboxes is the Tegra Combined UART. For this
purpose, we use interrupts to receive data, and spinning to wait for
the transmit mailbox to be emptied to minimize unnecessary overhead.
Based on work by Mikko Perttunen <mperttunen@nvidia.com>.
