Fix a real problem for SPRD's mailbox driver in patch 1/3.
Add supplementary inbox support for newly added sc9863a in patch 3/3 and
change dt bindings yaml accordingly in patch 2/3.
Changes Log:
V3:
- Add Reviewed-by tag from Baolin for driver code.
- Change interrupt-names
From: Orson Zhai
Unisoc mailbox has no way to be enabled/disabled for any single channel.
They can only be set to startup or shutdown as a whole device at same time.
Add a variable to count references to avoid mailbox FIFO being reset

From: Orson Zhai
We add an optional supp-outbox interrupt support to SPRD mailbox driver
with newly added sc9863a support and change to configure interrupts with

Some sensors connected to Unisoc mailbox will send data very frequently.
This makes channel 0 very busy and the messages from other remote cores
not able to be handled as soon as possible.
It's a trick (un-documented) from Unisoc ASIC designers to resolve this

Move all client-private data out of `struct kcs_bmc` into the KCS client

With this change the KCS BMC core code now only concerns itself with

expected separation of concerns. Further, the change clears the path
Now that we have untangled the data-structures, split the userspace

Soon it will be possible for one KCS device to have multiple associated
chardevs exposed to userspace (for IPMI and raw-style access). However,
don't prevent userspace from:
1. Opening more than one chardev at a time, or
2. Opening the same chardev more than once.
System behaviour is undefined
The existing IPMI chardev encodes IPMI behaviours as the name suggests.
However, KCS devices are useful beyond IPMI (or keyboards), as they
provide a means to generate IRQs and exchange arbitrary data between a
BMC and its host system.
Implement a "raw" KCS character device that exposes the IDR,

Your understanding is very correct,this is what my patch wants to do

At some time, the original code may return non zero value, force return 0
if operation finished.

Hi all,
Warning: Some of the branches in linux-next may still based on v5.12-rc1,
so please be careful if you are trying to bisect a bug.
News: if your -next included tree is based on Linus' tree tag
v5.12-rc1{,-dontuse} (or somewhere between v5.11 and that tag), please
consider rebasing it onto

From: Sean Christopherson
Add a misc device /dev/sgx_vepc to allow userspace to allocate "raw" EPC
without an associated enclave. The intended and only known use case for
raw EPC allocation is to expose EPC to a KVM guest, hence the 'vepc'
moniker, virt.{c,h} files and X86_SGX_KVM Kconfig.
SGX
From: Sean Christopherson
Expose SGX architectural structures, as KVM will use many of the
architectural constants and structs to virtualize SGX.
Name the new header file as asm/sgx.h, rather than asm/sgx_arch.h, to
have single header to provide SGX facilities to share with other kernel
Modify sgx_init() to always try to initialize the virtual EPC driver,
even if the SGX driver is disabled. The SGX driver might be disabled
if SGX Launch Control is in locked mode, or not supported in the
hardware at all. This allows (non-Linux) guests that support non-LC
configurations to use
From: Sean Christopherson
The kernel will currently disable all SGX support if the hardware does
not support launch control. Make it more permissive to allow SGX
virtualization on systems without Launch Control support. This will
allow KVM to expose SGX to guests that have less-strict
Move SGX_LC feature bit to CPUID dependency table to make clearing all
SGX feature bits easier. Also remove clear_sgx_caps() since it is just
a wrapper of setup_clear_cpu_cap(X86_FEATURE_SGX) now.

From: Sean Christopherson
Add SGX1 and SGX2 feature flags, via CPUID.0x12.0x0.EAX, as scattered
features, since adding a new leaf for only two bits would be wasteful.
As part of virtualizing SGX, KVM will expose the SGX CPUID leafs to its
guest, and to do so correctly needs to query hardware and
EREMOVE takes a page and removes any association between that page and
an enclave. It must be run on a page before it can be added into
another enclave. Currently, EREMOVE is run as part of pages being freed
into the SGX page allocator. It is not expected to fail.
KVM does not track how guest
From: Sean Christopherson
SGX driver can accurately track how enclave pages are used. This
enables SECS to be specifically targeted and EREMOVE'd only after all
child pages have been EREMOVE'd. This ensures that SGX driver will
never encounter SGX_CHILD_PRESENT in normal operation.
