Subject: [PATCH v11 7/12] arch/*/asm/io.h: Add ioremap_wt() to all architectures
Date: Fri, 29 May 2015 16:59:05 -0600 [thread overview]
Message-ID: <1432940350-1802-8-git-send-email-toshi.kani@hp.com> (raw)
In-Reply-To: <1432940350-1802-1-git-send-email-toshi.kani@hp.com>
From: Toshi Kani <toshi.kani@hp.com>
This patch adds ioremap_wt() to all arch-specific asm/io.h which
define ioremap_wc() locally. These arch-specific asm/io.h do not
include <asm-generic/iomap.h>. Some of them include
<asm-generic/io.h>, but ioremap_wt() is defined for consistency
since they define all ioremap_xxx locally.
ioremap_wt() is defined indentical to ioremap_nocache() to all
architectures without WT support.
frv and m68k already have ioremap_writethrough(). This patch
implements ioremap_wt() indetical to ioremap_writethrough() and
defines ARCH_HAS_IOREMAP_WT in both architectures.
This patch allows generic drivers to use ioremap_wt().

Subject: [PATCH v11 7/12] arch/*/asm/io.h: Add ioremap_wt() to all architectures
Date: Fri, 29 May 2015 16:59:05 -0600 [thread overview]
Message-ID: <1432940350-1802-8-git-send-email-toshi.kani@hp.com> (raw)
In-Reply-To: <1432940350-1802-1-git-send-email-toshi.kani@hp.com>
From: Toshi Kani <toshi.kani@hp.com>
This patch adds ioremap_wt() to all arch-specific asm/io.h which
define ioremap_wc() locally. These arch-specific asm/io.h do not
include <asm-generic/iomap.h>. Some of them include
<asm-generic/io.h>, but ioremap_wt() is defined for consistency
since they define all ioremap_xxx locally.
ioremap_wt() is defined indentical to ioremap_nocache() to all
architectures without WT support.
frv and m68k already have ioremap_writethrough(). This patch
implements ioremap_wt() indetical to ioremap_writethrough() and
defines ARCH_HAS_IOREMAP_WT in both architectures.
This patch allows generic drivers to use ioremap_wt().
