Binbin Zhou b846085eed dt-bindings: interrupt-controller: loongson,liointc: Document address-cells 
The Loongson local I/O interrupt controller can be referenced in
interrupt-map properties (e.g. in
arch/loongarch/boot/dts/loongson-2k1000.dtsi), thus the nodes should
have address-cells property.

maoxiaochuan b75aa49c40 rtc: loongson: Add Loongson-2K0300 support 
The Loongson-2K0300's rtc hardware design is similar to that of the
Loongson-1B, but it does not support the alarm feature.

Introduce `LOONGSON_RTC_ALARM_WORKAROUND`, which indicates a chip that
does not support the alarm feature, and rewrite the related logic in
`loongson_rtc_alarm_setting()`.

Binbin Zhou 5f88366873 dt-bindings: rtc: loongson: Document Loongson-2K0300 compatible 
Add "loongson,ls2k0300-rtc" dedicated compatible to represent the RTC
interface of the Loongson-2K0300 chip.

Its hardware design is similar to that of the Loongson-1B, but it does
not support the alarm feature.

Binbin Zhou d6ddf0dfe0 dt-bindings: rtc: loongson: Correct Loongson-1C interrupts property 
The `interrupts` property indicates an RTC alarm interrupt, which is
required for RTCs that support the alarm feature, which is not supported
by the Loongson-1C RTC. We exclude it for a more accurate description.

Changing the `allowed` property is ABI-breaking behavior, but
throughout the existing Loongson DTS{i}, the description of the RTC
nodes conforms to the modified bingding rules.

Thus, the existing Loongson DTS{i} will not be affected.

Bibo Mao 9238506cb9 crypto: virtio: Replace package id with numa node id 
With multiple virtio crypto devices supported with different NUMA
nodes, when crypto session is created, it will search virtio crypto
device with the same numa node of current CPU.

Here API topology_physical_package_id() is replaced with cpu_to_node()
since package id is physical concept, and one package id have multiple
memory numa id.

Bibo Mao 181aef9b99 crypto: virtio: Add spinlock protection with virtqueue notification 
When VM boots with one virtio-crypto PCI device and builtin backend,
run openssl benchmark command with multiple processes, such as
  openssl speed -evp aes-128-cbc -engine afalg  -seconds 10 -multi 32

openssl processes will hangup and there is error reported like this:
 virtio_crypto virtio0: dataq.0:id 3 is not a head!

It seems that the data virtqueue need protection when it is handled
for virtio done notification. If the spinlock protection is added
in virtcrypto_done_task(), openssl benchmark with multiple processes
works well.

Brian Masney 4fd65e99a7 clk: loongson1: convert from divider_round_rate() to divider_determine_rate() 
The divider_round_rate() function is now deprecated, so let's migrate
to divider_determine_rate() instead so that this deprecated API can be
removed.

Note that when the main function itself was migrated to use
determine_rate, this was mistakenly converted to:

    req->rate = divider_round_rate(...)

This is invalid in the case when an error occurs since it can set the
rate to a negative value.
