bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

soc: mediatek: mtk-cmdq: Add mminfra_offset adjustment for DRAM addresses
Since GCE has been moved to MMINFRA in MT8196, all transactions from
MMINFRA to DRAM will have their addresses adjusted by subtracting a
mminfra_offset.

Therefore, the CMDQ helper driver needs to get the mminfra_offset value
of the SoC from cmdq_mbox_priv of cmdq_pkt and then add it to the DRAM
address when generating instructions to ensure GCE accesses the correct
DRAM address. CMDQ users can then call CMDQ helper APIs as usual.

soc: mediatek: mtk-cmdq: Extend cmdq_pkt_write API for SoCs without subsys ID
This patch extends the cmdq_pkt_write API to support SoCs that do not
have subsys ID mapping by introducing new register write APIs:
- cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() replace
  cmdq_pkt_write()
- cmdq_pkt_write_mask_pa() and cmdq_pkt_write_mask_subsys() replace
  cmdq_pkt_write_mask()

To ensure consistent function pointer interfaces, both
cmdq_pkt_write_pa() and cmdq_pkt_write_subsys() provide subsys and
pa_base parameters. This unifies how register writes are invoked,
regardless of whether subsys ID is supported by the device.

All GCEs support writing registers by PA (with mask) without subsys,
but this requires extra GCE instructions to convert the PA into a GCE
readable format, reducing performance compared to using subsys directly.
Therefore, subsys is preferred for register writes when available.

API documentation and function pointer declarations in cmdq_client_reg
have been updated. The original write APIs will be removed after all
CMDQ users transition to the new interfaces.

soc: mediatek: mtk-cmdq: Add pa_base parsing for hardware without subsys ID support
When GCE executes instructions, it typically locates the corresponding
hardware register using the subsys ID. For hardware that does not
support subsys ID, the subsys ID is set to an invalid value, and the
physical address must be used to generate GCE instructions.

The main advantage of using subsys ID is to reduce the number of
instructions. Without subsys ID, an additional `ASSIGN` instruction
is needed to assign the high bytes of the physical address, which can
impact performance if too many instructions are required. However, if
the hardware does not support subsys ID, using the physical address
is the only option to achieve the same functionality.

This commit adds a pa_base parsing flow to the cmdq_client_reg structure
to handle hardware without subsys ID support.

soc: mediatek: mtk-dvfsrc: Rework bandwidth calculations
The code, as it is, plays fast and loose with bandwidth units. It also
doesn't specify its constraints in the actual maximum hardware value,
but as some roundabout thing that then ends up multiplied into the
actual hardware value constraint after some indirections. In part, this
is due to the use of individual members for storing each limit, instead
of making it possible to index them by type.

Rework all of this by adding const array members indexed by the
bandwidth type enum to the soc_data struct. This array expresses the
actual hardware value limitations, not a factor thereof.

Use the clamp function macro to clamp the values between the minimum and
maximum constraints after all the calculations, which also means the
code doesn't write nonsense to a hardware register when the math is
wrong, as it'll constrain after all the calculations.

Pass the type as the actual enum type as well, and not as an int. If
there's some type checking that can be extracted from the function
signature, then we may as well use it.

Don't needlessly explicitly cast return values to the return type
either; this is both unnecessary and makes it harder to spot type safety
issues.

soc: mediatek: mtk-mutex: Fix confusing usage of MUTEX_MOD2
The usage of MUTEX_MOD1 and MUTEX_MOD2 for calculating mod settings
over 32 has been confusing. To improve consistency and clarity, these
defines need to fit into the same MUTEX_MOD define as possible.

However, MUTEX_MOD1 cannot be directly used for all SoCs because,
for example, the mod1 register (0x34) of MT2712 is not adjacent to
its mod0 register (0x2c). To address this, a `mutex_mod1_reg` field
is introduced in the mutex driver data structure. This allows all
SoCs to use a unified MUTEX_MOD to determine their register offsets.

With this change, the separate usage of MUTEX_MOD1 and MUTEX_MOD2 is
eliminated, simplifying the logic for obtaining offsets and mod IDs.

The mmsys driver reads the routing table and writes to the

this effectively writes .. nothing .. to the hardware.

That would never work, and if the display controller was
actually working with the mmsys doing no routing at all,
that was only because the bootloader was correctly setting
the display controller routing registers before booting the
kernel, and the mmsys was never reset.

Make this table to actually set the routing by adding the
correct register masks to it.

While at it, also change MOUT val definitions to BIT(x), as
the MOUT registers are effectively checking for each bit to
enable output to the corresponding HW.
Please note that, for this SoC, only the MOUT registers are
checking bits (as those can enable multiple outputs), while
the others are purely reading a number to select an input.

This connection is activated by writing a (masked) value in each

Failing to set the right path does not give any meaningful error
and makes things to simply not work as the data will either not
be retrieved from the right input port, or will be written to
the wrong output port (or both): since a misconfiguration may
effectively still be a possibly correct configuration at the HW
level, this may be only giving side effects in terms of simply
getting no functionality but, again, no errors.

declared register mask is wrong as it is set as GENMASK(1, 0).

Register MERGE4_MOUT_EN in VDO1 has four used bits [3, 0] so
fix the mask to reflect that.
That, in turn, allows the mmsys driver to actually set BIT(2)
in this register, fixing the MERGE4 output to DPI1 selection.

soc: mediatek: mtk-socinfo: Avoid using machine attribute in SoC detection log
The recently introduced SoC attribute info rework avoided modifying the
machine attribut but still used it in the log message on successful SoC
matching. It leads to print a confusing log about a board-related info
(read from devicetree) and not about the matched SoC:
```
mtk-socinfo mtk-socinfo.0.auto: MediaTek MediaTek Genio-510 EVK SoC
  detected
```

So, fix the dev_info format to display SoC family and name attribute
instead.
```
mtk-socinfo mtk-socinfo.0.auto: MediaTek Genio 510 (MT8370) SoC detected.

soc: mediatek: mtk-socinfo: Restructure SoC attribute information
So far, the MediaTek socinfo driver populates the SoC information as
follows:
  - family:  "MediaTek"
  - machine: "<marketing_name> (<soc_name>)"
      e.g.,  "Kompanio 1380 (MT8195)"
  - soc_id:  <null>

This approach has some drawbacks:
1.  "soc_id" can be used for showing the SoC name (e.g. "MT8195"), while
    it's currently unused.
2.  The newer socinfo API automatically populates the "machine"
    attribute with the model name from board DTS if unspecified, which
    we may want to preserve if possible.
3.  "machine" combines the marketing name and SoC name, making it
    trickier to parse. Ideally, the marketing name and SoC name should
    be in separate attributes so userspace to utilize them as needed.
4.  There's no guarantee that the marketing name will be announced along
    with the SoC name. If either is undetermined, the current design
    will result in a malformed "machine" output. This is observed on
    some newer MediaTek platforms, where the marketing name is still
    undetermined but the SoC information needs to be settled for device
    registration and validation before launch.

To address these points, this commit proposes a new theme to display the
SoC information:
  - family:  "MediaTek <marketing_name>"
      e.g.,  "MediaTek Kompanio 1380"
  - machine: "<dt_model_name>" (auto-populated)
      e.g.,  "Acer Tomato (rev1) board"
  - soc_id:  "<soc_name>"
      e.g.,  "MT8195"

Moreover, if the marketing name is not provided, the driver displays
"MediaTek" in the "family" attribute instead, consistent with the
previous behavior.

Restructure the way driver populates the SoC information as described
above.

Note that Mediatek-based Chromebooks are the primary consumers of this
socinfo driver, and Google has prepared corresponding userspace changes
to comply with this update, so the impact to userspace is controlled.

soc: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/soc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way do a few whitespace changes to make indention consistent.

The Mali GPU in mt8188 also requires coupled power supplies,
that is, the "vsram" voltage should follow the "vgpu" voltage.
Therefore add the compatible to enable this coupling behavior.

soc: mediatek: mtk-cmdq: Move cmdq_instruction init to declaration
Move, where possible, the initialization of struct cmdq_instruction
variables to their declaration to compress the code.

While at it, also change an instance of open-coded mask to use the
GENMASK() macro instead, and instances of `ret = func(); return ret;`
to the equivalent (but shorter) `return func()`.

soc: mediatek: mtk-cmdq: Move mask build and append to function
Move the CMDQ_CODE_MASK packet build and append logic to a new
cmdq_pkt_mask() function; this reduces code duplication by 4x.

soc: mediatek: Add MediaTek DVFS Resource Collector (DVFSRC) driver
The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
Hardware module used to collect all the requests from both software and the
various remote processors embedded into the SoC and decide about a minimum
operating voltage and a minimum DRAM frequency to fulfill those requests in
an effort to provide the best achievable performance per watt.

This hardware IP is capable of transparently performing direct register R/W
on all of the DVFSRC-controlled regulators and SoC bandwidth knobs.

This driver includes support for MT8183, MT8192 and MT8195.

soc: mediatek: mtk-mutex: Reduce type size for mtk_mutex_data members
All of mutex_mod and mutex_table_mod contain an array of bit
numbers, which can go from 0 to 63, it is hence not needed to
use an unsigned 32-bits integer to store that: change them to
unsigned 8-bits instead.

As for the mutex_sof table since this directly contains the values
to write to the DISP_MUTEXn_CTL register, which has only bits [13:0]
(so this register is effectively 14 bits long), change that to use
unsigned 16-bits.

The type of mutex_{mod,sof}_reg was also changed to 16 bits, as
the maximum value that those will ever have is 0x800, because it
calculates as 0x30 + (0x20 * n) where n's maximum value is 63.

This reduces module size and brings no functional changes.
