[RFC PATCH 0/2] Input: add fts2ba61y touchscreen driver
Posted by Eric Gonçalves 2 weeks, 6 days ago
This patchset adds support for the ST-Microelectronics FTS2BA61Y,
a capacitive multi-touch touchscreen controller. this touchscreen
is used in many mobile devices, like ones from the Galaxy S22 series
and the Z Fold 5. Ivaylo Ivanov wrote the driver originally,
and I'm upstreaming it on his behalf.

Thanks!

RFC means patchset is not ready, so please always mention why it is not
ready or what you expect here.

Best regards,

I'm not sure if naming the compatible as it is currently is correct.
The specific thing about this IC seems to be that it's flashed with
samsung-made firmware, so I need to confirm that:
- we don't want to match compatible with the IC name (the same IC may
be shipped with different fw on other devices)
- maintainers wouldn't want us to merge it with some other driver

Best regards,
Ivaylo
