Subject: [PATCH RESEND v2 1/2] m68k/atari: add platform device for Falcon IDE port
Date: Thu, 26 Sep 2019 15:54:23 +1200
Message-ID: <1569470064-3977-2-git-send-email-schmitzmic@gmail.com> (raw)
In-Reply-To: <1569470064-3977-1-git-send-email-schmitzmic@gmail.com>

Autoloading of Falcon IDE driver modules requires converting
these drivers to platform drivers.

Add platform device for Falcon IDE interface in Atari platform
setup code in preparation for this.

Signed-off-by: Michael Schmitz <schmitzmic@gmail.com>

Changes from RFC

- fix region size (spotted by Szymon Bieganski <S.Bieganski@chello.nl>)
- define IDE interface address in atari/config.c, create platform device
  always (suggested by Geert Uytterhoeven <geert@linux-m68k.org>)

Changes from v1

- add error checking for Falcon IDE platform device register
