Jiri, originally the drivers/hid/amd-sfh-hid/ changes
were posted as part of this series:

https://lore.kernel.org/platform-driver-x86/20231204101548.1458499-1-Shyam-sundar.S-k@xxxxxxx/

specifically in these patches:

https://lore.kernel.org/platform-driver-x86/20231204101548.1458499-14-Shyam-sundar.S-k@xxxxxxx/
https://lore.kernel.org/platform-driver-x86/20231204101548.1458499-15-Shyam-sundar.S-k@xxxxxxx/
https://lore.kernel.org/platform-driver-x86/20231204101548.1458499-16-Shyam-sundar.S-k@xxxxxxx/

Where the last 2 patches introduce both the HID changes and the drivers/platform/x86/amd/pmf/...
consumer of the HID changes in one go.

I have asked Shyam to split out the HID changes:
https://lore.kernel.org/platform-driver-x86/ad064333-48a4-4cfa-9428-69e8a7c44667@xxxxxxxxxx/

"""
But this patch also needs to have its HID parts split out
from the rest and the HID patches need to be merged
separately.

Since the merge-window is getting close I would like
to propose the following:

1. Send a v7 addressing review remarks consisting of
only patches 1-12, assuming all review remarks are
fixed in v7 I can merge that then.

2. Send a 3 patch HID patch series separately:

[PATCH 1/3] HID: amd_sfh: rename float_to_int() to amd_sfh_float_to_int()
[PATCH 2/3] HID: amd_sfh: adding the HID hpd bits + amd_get_sfh_info() function
[PATCH 3/3] HID: amd_sfh: adding the HID als bits

3. Once v7 of patches 1-12 + hopefully the 3 patch HID series have
landed in 6.8-rc1 then I would be willing to take a patch using
amd_get_sfh_info() to implement hpd + als support in the spc code
as a fix for 6.8-rc# .
"""

I have merged patches 1-12 of the AMD PMF series already.
So assuming there are no other objections against the HID
changes it would be great if these can still make it into
6.8-rc1 then Shyam can re-send the AMD PMF changes which
consume the new HID API as a separate patch and then I'll
send that to Linus once the HID changes have been merged
by Linus.

Note I understand if the timing does not work out
in that case the HID changes + the AMD PMF patches which
consume the new HID API can wait for the next cycle.

If this is going to wait for the next cycle, then please
send me a pull-request for an immutable branch with
the HID changes in there so that I can merge that
into pdx86/for-next before merging the AMD PMF changes.

Regards,

Hans
