Subject: [PATCH 0/3] Input: st1232 - fixes for resolution reading
Date: Tue, 29 Dec 2020 17:25:58 +0100	[thread overview]
Message-ID: <20201229162601.2154566-1-geert+renesas@glider.be> (raw)

	Hi Dmitry, Andrej,

The recent commit 3a54a215410b1650 ("Input: st1232 - add support
resolution reading") broke probing of the st1232 touchscreen on
r8a7740/armadillo:

    st1232-ts 1-0055: Failed to read resolution: -6

Upon investigation, this turned out to be a little bit more complicated
than expected, hence I wrote not one but three fixes.

Thanks for your comments!

Geert Uytterhoeven (3):
  Input: st1232 - fix off-by-one error in resolution handling
  Input: st1232 - do not read more bytes than needed
  Input: st1232 - wait until device is ready before reading resolution

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
