fbeddb4a76 wifi: rtl8xxxu: Add LED control code for RTL8192CU family
Also, don't set bit 7 of LEDCFG2 for RTL8192CU. If bit 7 is set the LED
never turns on. In this family only RTL8188CUS needs bit 7 of LEDCFG2
set.

Software control (on/off) and hardware control (automatic blinking)
tested with Netcore NW362 (RTL8192CU).

110951b8fa wifi: rtl8xxxu: Add separate MAC init table for RTL8192CU
Until now RTL8192CU family was using the MAC init table from RTL8723AU,
but these tables are not identical in the two vendor drivers. Import
the correct table for RTL8192CU.

Also move the existing MAC init table to rtl8xxxu_8723a.c, which is
the only remaining user.

Tested with the Netcore NW362 (RTL8192CU).

734b5def91 thermal/drivers/loongson2: Add Loongson-2K2000 support
The Loongson-2K2000 and Loongson-2K1000 have similar thermal sensors,
except that the temperature is read differently.

In particular, the temperature output registers of the Loongson-2K2000
are defined in the chip configuration domain and are read in a different
way.

c8c4353685 dt-bindings: thermal: loongson,ls2k-thermal: Fix incorrect compatible definition
The temperature output register of the Loongson-2K2000 is defined in the
chip configuration domain, which is different from the Loongson-2K1000,
so it can't be fallbacked.

We need to use two groups of registers to describe it: the first group
is the high and low temperature threshold setting register; the second
group is the temperature output register.

It is true that this fix will cause ABI corruption, but it is necessary
otherwise the Loongson-2K2000 temperature sensor will not work properly.

63d23fb781 thermal/drivers/rcar_gen3: Update temperature approximation calculation
The initial driver used a formula to approximate the temperature and
register values reversed engineered from an out-of-tree BSP driver. This
was needed as the datasheet at the time did not contain any information
on how to do this. Later Gen3 (Rev 2.30) and Gen4 (all) now contains
this information.

Update the approximation formula to use the datasheet's information
instead of the reversed-engineered one.

On an idle M3-N without fused calibration values for PTAT and THCODE the
old formula reports,

    zone0: 52000
    zone1: 53000
    zone2: 52500

While the new formula under the same circumstances reports,

    zone0: 52500
    zone1: 54000
    zone2: 54000

566e0ea7d0 thermal/drivers/rcar_gen3: Move Tj_T storage to shared private data

read from the first TSC zone on the device if calibration data is fused,
or from fallback values in the driver itself. The value calculated is
shared among all TSC zones.

Move the Tj_T constant to the shared private data structure instead of
duplicating it in each TSC private data. This requires adding a pointer
to the shared data to the TSC private data structure. This back pointer
make it easier to further rework the temperature conversion logic.

====================
net: stmmac: Fix MAC-capabilities procedure

The series got born as a result of the discussions around the recent
Yanteng' series adding the Loongson LS7A1000, LS2K1000, LS7A2000, LS2K2000
MACs support:
Link: https://lore.kernel.org/netdev/fu3f6uoakylnb6eijllakeu5i4okcyqq7sfafhp5efaocbsrwe@w74xe7gb6x7p

In particular the Yanteng' patchset needed to implement the Loongson
MAC-specific constraints applied to the link speed and link duplex mode.
As a result of the discussion with Russel the next preliminary patch was
born:
Link: https://lore.kernel.org/netdev/df31e8bcf74b3b4ddb7ddf5a1c371390f16a2ad5.1712917541.git.siyanteng@loongson.cn

The patch above was a temporal solution utilized by Yanteng for further
developments and to move on with the on-going review. This patchset is a
refactored version of that single patch with formatting required for the
fixes patches.

The main part of the series has already been merged in on v1 stage. The
leftover is the cleanup patches which rename
stmmac_ops::phylink_get_caps() callback to stmmac_ops::update_caps() and
move the MAC-capabilities init/re-init to the phylink MAC-capabilities
getter.

Changelog v2:

f951a64922 net: stmmac: Move MAC caps init to phylink MAC caps getter
After a set of recent fixes the stmmac_phy_setup() and
stmmac_reinit_queues() methods have turned to having some duplicated code.
Let's get rid from the duplication by moving the MAC-capabilities
initialization to the PHYLINK MAC-capabilities getter. The getter is
called during each network device interface open/close cycle. So the
MAC-capabilities will be initialized in generic device open procedure and
in case of the Tx/Rx queues re-initialization as the original code
semantics implies.

dc144baeb4 net: stmmac: Rename phylink_get_caps() callback to update_caps()
Since recent commits the stmmac_ops::phylink_get_caps() callback has no
longer been responsible for the phylink MAC capabilities getting, but
merely updates the MAC capabilities in the mac_device_info:🔗:caps
field. Rename the callback to comply with the what the method does now.

soc: mediatek: socinfo: Advertise about unknown MediaTek SoC
In case we're running on a MediaTek SoC that is not declared in the
socinfo_data_table, print a message stating that and, with it, also
print out the read eFuse data: this allows to easily add a new SoC
in the table, granted that its actual soc/segment/marketing names
are already previously known.

This is especially useful when booting an already known SoC that
already has socinfo support, but has a different silicon version
and/or revision, hence different model information in the eFuses.

soc: mediatek: cmdq: Don't log an error when gce-client-reg is not found
Most of the callers to this function do not require CMDQ support, it is
optional, so the missing property shouldn't cause an error message.
However, it could result on degraded performance, so the fact that it's
missing should still be alerted. Furthermore, the callers that do
require CMDQ support already log at the error level when an error is
returned.

Change the log message in this helper to be printed at the warning level
instead.

soc: mediatek: mtk-cmdq: Add cmdq_pkt_acquire_event() function
Add cmdq_pkt_acquire_event() function to support CMDQ user making
an instruction for acquiring event.

CMDQ users can use cmdq_pkt_acquire_event() as `mutex_lock`
and cmdq_pkt_clear_event() as `mutex_unlock` to protect the global
resource modified instructions between them.

cmdq_pkt_acquire_event() would wait for event to be cleared.
After event is cleared by cmdq_pkt_clear_event() in other GCE threads,
cmdq_pkt_acquire_event() would set event and keep executing next
instruction. So the mutex would work like this:

    cmdq_pkt_acquire_event() /* mutex lock */

    /* critical secton instructions that modified global resource */

    cmdq_pkt_clear_event() /* mutex unlock */

Prevent the critical section instructions from being affected by other
GCE threads.

Add cmdq_pkt_poll_addr function to support CMDQ user making
an instruction for polling a specific address of hardware rigster
to check the value with or without mask.

POLL is a legacy operation in GCE, so it does not support SPR and
CMDQ_CODE_LOGIC. To support polling the register address which doesn't
have the subsys id, CMDQ users need to make an instruction with GPR and
CMDQ_CODE_MASK operation to move the register address to be poll into GPR.
Then users can make an POLL instruction with GPR to poll the register
address assigned in previous instruction.
