   sooo the qualcomm qcs6490 has at least the following names, all for the same chip (?):

   - QCS6490
   - Yupik
   - SM7325
   - Snapdragon 7c+ Gen 3
   - Snapdragon 778G

   now my question is: why

     @mntmn Note that the different variants (QC*6490, SM7325, SC7280, SM7325-AE, SM7325-AF) all do have minor differences but they're generally limited to clock speeds or some minor difference in GPU, but 99% is the same, that's why in mainline Linux they're all supported under the "SC7280" name (that name just because it was the first from Yupik to be supported upstream, and upstream doesn't take the downstream codenames)

     * QCS6490: The number of the SoC
     * Yupik: Linux (HLOS) codename for the family of SoCs which includes QCS6490 but also QCM6490 (the variant with modem), SM7325, SC7280, etc
     * SM7325: Snapdragon variant of this SoC for phones
     * Snapdragon 7c+ Gen 3: Compute variant of this SoC for laptops
     * Snapdragon 778G: Marketing name for SM7325 - see there.

     There's also the codename "kodiak" which is present in non-HLOS sources (so e.g. bootloader, modem, etc) which generally equals Yupik
