Subject: [PATCH 27/41] ARM: omap1: use pci_remap_iospace() for omap_cf
Date: Tue, 19 Apr 2022 15:37:09 +0200	[thread overview]
Message-ID: <20220419133723.1394715-28-arnd@kernel.org> (raw)
In-Reply-To: <20220419133723.1394715-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

The ISA I/O space handling in omap_cf is incompatible with
PCI drivers in a multiplatform kernel, and requires a custom
mach/io.h.

Change the driver to use pci_remap_iospace() like PCI drivers do,
so the generic ioport access can work across platforms.

To actually use that code, we have to select CONFIG_PCI
here.

Subject: [PATCH 27/41] ARM: omap1: use pci_remap_iospace() for omap_cf
Date: Tue, 19 Apr 2022 15:37:09 +0200	[thread overview]
Message-ID: <20220419133723.1394715-28-arnd@kernel.org> (raw)
In-Reply-To: <20220419133723.1394715-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

The ISA I/O space handling in omap_cf is incompatible with
PCI drivers in a multiplatform kernel, and requires a custom
mach/io.h.

Change the driver to use pci_remap_iospace() like PCI drivers do,
so the generic ioport access can work across platforms.

To actually use that code, we have to select CONFIG_PCI
here.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
