Subject: [PATCH 04/16] net: dsa: mt7530: make some noise if register read
fails
Simply returning the negative error value instead of the read value
doesn't seem like a good idea. Return 0 instead and add WARN_ON_ONCE(1)
so this kind of error will not go unnoticed.

Subject: [PATCH 05/16] net: dsa: mt7530: refactor SGMII PCS creation
Instead of macro templates use a dedidated function and allocated
regmap_config when creating the regmaps for the pcs-mtk-lynxi
instances.
This is in preparation to switching to use unlocked regmap accessors
and have regmap's locking API handle locking for us.

Subject: [PATCH 06/16] net: dsa: mt7530: use unlocked regmap accessors
Instead of wrapping the locked register accessor functions, use the
unlocked variants and add locking wrapper functions to let regmap
handle the locking.
This is a preparation towards being able to always use regmap to
access switch registers instead of open-coded accessor functions.

Subject: [PATCH 09/16] net: dsa: mt7530: introduce mutex helpers
As the MDIO bus lock only needs to be involved if actually operating
on an MDIO-connected switch we will need to skip locking for built-in
switches which are accessed via MMIO.
Create helper functions which simplify that upcoming change.

Subject: [PATCH 10/16] net: dsa: mt7530: move p5_intf_modes() function to
mt7530.c
In preparation of splitting mt7530.c into a driver for MDIO-connected
as well as MDIO-accessed built-in switches on one hand and MMIO-accessed
built-in switches move the p5_inft_modes() function from mt7530.h to
mt7530.c. The function is only needed there and will trigger a compiler
warning about a defined but unused function otherwise when including
mt7530.h in the to-be-introduced bus-specific drivers.

From cb675afcddbbeb2bfa6596e3bc236bc026cd425f Mon Sep 17 00:00:00 2001
From: Daniel Golle <daniel@makrotopia.org>
Date: Mon, 3 Apr 2023 02:19:13 +0100
Subject: [PATCH 14/16] net: dsa: mt7530: introduce separate MDIO driver
Split MT7530 switch driver into a common part and a part specific
for MDIO connected switches and multi-chip modules.
Move MDIO-specific functions to newly introduced mt7530-mdio.c while
keeping the common parts in mt7530.c.
Introduce new Kconfig symbol CONFIG_NET_DSA_MT7530_MDIO which is
implied by CONFIG_NET_DSA_MT7530.

Subject: [PATCH 15/16] net: dsa: mt7530: skip locking if MDIO bus isn't
present
As MT7530 and MT7531 internally use 32-bit wide registers, each access
to any register of the switch requires several operations on the MDIO
bus. Hence if there is congruent access, e.g. due to PCS or PHY
polling, this can mess up and interfere with another ongoing register
access sequence.
However, the MDIO bus mutex is only relevant for MDIO-connected
switches. Prepare switches which have there registers directly mapped
into the SoCs register space via MMIO which do not require such
locking. There we can simply use regmap's default locking mechanism.
Hence guard mutex operations to only be performed in case of MDIO
connected switches.

Subject: [PATCH 16/16] net: dsa: mt7530: introduce driver for MT7988 built-in
switch
Add driver for the built-in Gigabit Ethernet switch which can be found
in the MediaTek MT7988 SoC.
The switch shares most of its design with MT7530 and MT7531, but has
it's registers mapped into the SoCs register space rather than being
connected externally or internally via MDIO.
Introduce a new platform driver to support that.

From 91daa4f62ce878b6e1ac5908aceb83550332447f Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: dsa: mt7530: fix support for MT7531BE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
There are two variants of the MT7531 switch IC which got different
features (and pins) regarding port 5:
* MT7531AE: SGMII/1000Base-X/2500Base-X SerDes PCS
* MT7531BE: RGMII
Moving the creation of the SerDes PCS from mt753x_setup to mt7530_probe
with commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation
to mt7530_probe function") works fine for MT7531AE which got two
instances of mtk-pcs-lynxi, however, MT7531BE requires mt7531_pll_setup
to setup clocks before the single PCS on port 6 (usually used as CPU
port) starts to work and hence the PCS creation failed on MT7531BE.
Fix this by introducing a pointer to mt7531_create_sgmii function in
struct mt7530_priv and call it again at the end of mt753x_setup like it
was before commit 6de285229773 ("net: dsa: mt7530: move SGMII PCS
creation to mt7530_probe function").
Fixes: 6de285229773 ("net: dsa: mt7530: move SGMII PCS creation to mt7530_probe function")

Subject: [PATCH 1/7] net: ethernet: mtk_eth_soc: add MTK_NETSYS_V1 capability
bit
Introduce MTK_NETSYS_V1 bit in the device capabilities for
MT7621/MT7622/MT7623/MT7628/MT7629 SoCs.
Use !MTK_NETSYS_V1 instead of MTK_NETSYS_V2 in the driver codebase.
This is a preliminary patch to introduce support for MT7988 SoC.

Subject: [PATCH 03/21] cpufreq: mediatek: Enable clocks and regulators
We need to enable regulators so that the max and min requested values will
be recorded.
The intermediate clock is not always enabled by CCF in different projects,
so we should enable it in the cpufreq driver.

Subject: [PATCH 06/21] cpufreq: mediatek: Record previous target vproc value
We found the buck voltage may not be exactly the same with what we set
because CPU may share the same buck with other module.
Therefore, we need to record the previous desired value instead of reading
it from regulators.

Subject: [PATCH 07/21] cpufreq: mediatek: Make sram regulator optional
For some MediaTek SoCs, like MT8186, it's possible that the sram regulator
is shared between CPU and CCI.
We hope regulator framework can return error for error handling rather
than a dummy handler from regulator_get api.
Therefore, we choose to use regulator_get_optional.

Voltages and shifts are defined as macros originally.
There are different requirements of these values for each MediaTek SoCs.
Therefore, we add the platform data and move these values into it.

Subject: [PATCH 10/21] cpufreq: mediatek: Refine
mtk_cpufreq_voltage_tracking()
Because the difference of sram and proc should in a range of min_volt_shift
and max_volt_shift. We need to adjust the sram and proc step by step.
We replace VOLT_TOL (voltage tolerance) with the platform data and update the
logic to determine the voltage boundary and invoking regulator_set_voltage.
- Use 'sram_min_volt' and 'sram_max_volt' to determine the voltage boundary
of sram regulator.
- Use (sram_min_volt - min_volt_shift) and 'proc_max_volt' to determine the
voltage boundary of vproc regulator.
Moreover, to prevent infinite loop when tracking voltage, we calculate the
maximum value for each platform data.
We assume min voltage is 0 and tracking target voltage using
min_volt_shift for each iteration.
The retry_max is 3 times of expeted iteration count.

One of the user for this opp notifier is MediaTek SVS.
The MediaTek Smart Voltage Scaling (SVS) is a hardware which calculates
suitable SVS bank voltages to OPP voltage table.

Subject: [PATCH 13/21] cpufreq: mediatek: Link CCI device to CPU
In some MediaTek SoCs, like MT8183, CPU and CCI share the same power
supplies. Cpufreq needs to check if CCI devfreq exists and wait until
CCI devfreq ready before scaling frequency.
Before CCI devfreq is ready, we record the voltage when booting to
kernel and use the max(cpu target voltage, booting voltage) to
prevent cpufreq adjust to the lower voltage which will cause the CCI
crash because of high frequency and low voltage.
- Add is_ccifreq_ready() to link CCI device to CPI, and CPU will start
DVFS when CCI is ready.
- Add platform data for MT8183.

Subject: [PATCH 18/21] cpufreq: mediatek: fix KP caused by handler usage after
regulator_put/clk_put
Any kind of failure in mtk_cpu_dvfs_info_init() will lead to calling
regulator_put() or clk_put() and the KP will occur since the regulator/clk
handlers are used after released in mtk_cpu_dvfs_info_release().
To prevent the usage after regulator_put()/clk_put(), the regulator/clk
handlers are addressed in a way of "Free the Last Thing Style".

Subject: [PATCH 19/21] cpufreq: mediatek: raise proc/sram max voltage for
MT8516
Since the upper boundary of proc/sram voltage of MT8516 is 1300 mV,
which is greater than the value of MT2701 1150 mV, we fix it by adding
the corresponding platform data and specify proc/sram_max_volt to
support MT8516.

Subject: [PATCH 20/21] cpufreq: mediatek: Raise proc and sram max voltage for
MT7622/7623
During the addition of SRAM voltage tracking for CCI scaling, this
driver got some voltage limits set for the vtrack algorithm: these
were moved to platform data first, then enforced in a later commit
6a17b3876bc8 ("cpufreq: mediatek: Refine mtk_cpufreq_voltage_tracking()")
using these as max values for the regulator_set_voltage() calls.
In this case, the vsram/vproc constraints for MT7622 and MT7623
were supposed to be the same as MT2701 (and a number of other SoCs),
but that turned out to be a mistake because the aforementioned two
SoCs' maximum voltage for both VPROC and VPROC_SRAM is 1.36V.
Fix that by adding new platform data for MT7622/7623 declaring the
right {proc,sram}_max_volt parameter.

+ The mute function uses 'mutein', 'muteout', and 'vdet' pins as the control

+ whatever the 'mutein' signal is, it will pull down the 'muteout' to force
+ speakers mute. this function is commonly used to prevent the speaker pop
+ noise during AC power turned off in the modern TV system design.
