Well, this list of users is definitely useful, but my main motivation is an easier to understand RTC subsystem. I just came this way where I spent some time trying to understand a complexity only to find out it is outdated and largely not used anymore. It could be simplified. Also, less code to maintain. > While I'm reviewing all your other series, do you mind having a look at > https://lore.kernel.org/all/20250205173918.600037-1-herve.codina@bootlin.com/ > It has been submitted a while ago now. Sure thing. Once I am done with my RTC task, I will have more time for I2C again \o/ Happy hacking, Wolfram --jY3mAlnLOCcRGPOk Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAmfadfoACgkQFA3kzBSg KbZWHA/+PPG+a2LivGfOTBZnJzEHRXBixfLC7239UoPzW/Vl0z6s1MwRn3B+Ao1h cg+N6LAqNIDghW2kL2/sWWx+dHAXxLjvzN7SSF1rtCRoeO57MV+AR741kQtnc1vM GNLURAQgo5jGHhPeKLec3AEqr5PGpAvPDSq7f2wP9DnUO0im0LpdWFdnzstul/nc CEfI+CZQbmfhGqYvQxMcKYibDy1e8LBXTQf3Aa/WNL2ovkOfxXNt89pJmvZhOEF0 AATcvKJ/4hB4O3O0WT1ihFQeinz4HHAKU2zFYWMByuEgsZJJDpICafFGZWiV5/2K xCUfNmRlgAK2yuzbRP+VK2mddd/V15ybxb5eNlSGOK/uunMHPabVZeBDhnJ8ggUv WsXRarnHgJ75Gnptb1ebGgI+NCPkpx0zA9zapu45B+SAwwQd5gzmhEJwikyA+teY haWaXOHKNeA88e38VTfyncjgBHo6zKI0H+Zh1vjW0tS3EHF7kysFdaJMYfwQCkCV +POCrMUQTopCe9zOZ1xmWL3yr5qbpBZlEQeZPYAIadcwmR4qrsPxR1F4+xWDmQWX LS59DUYZkHlyMngBVv6+o3zJirrrOTOsDTsolMXsyaMp1mz08xDaW788GL5fkQtL t5znkSpyhWOYH1tTN8duboWTA6iUbCWXQungPOPU2KEFBXZ03yg= =1Zpm -----END PGP SIGNATURE----- --jY3mAlnLOCcRGPOk--
