Subject: [PATCH v2 3/7] coccinelle: add xxxsetbitsXX converting spatch
Date:   Mon, 24 Sep 2018 19:04:12 +0000
Message-Id: <1537815856-31728-4-git-send-email-clabbe@baylibre.com>
In-Reply-To: <1537815856-31728-1-git-send-email-clabbe@baylibre.com>
References: <1537815856-31728-1-git-send-email-clabbe@baylibre.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch add a spatch which convert all open coded of setbits32/clrbits32/clrsetbits32
and their 64 bits counterparts.

Note that 64 and 32_relaxed are generated via
cp scripts/coccinelle/misc/setbits32.cocci scripts/coccinelle/misc/setbits32_relaxed.cocci
sed -i 's,readl,readl_relaxed,' scripts/coccinelle/misc/setbits32_relaxed.cocci
sed -i 's,writel,writel_relaxed,' scripts/coccinelle/misc/setbits32_relaxed.cocci
sed -i 's,setbits_le32,setbits_le32_relaxed,g' scripts/coccinelle/misc/setbits32_relaxed.cocci
sed -i 's,clrbits_le32,clrbits_le32_relaxed,g' scripts/coccinelle/misc/setbits32_relaxed.cocci
cp scripts/coccinelle/misc/setbits32.cocci scripts/coccinelle/misc/setbits64.cocci
sed -i 's,readl,readq,' scripts/coccinelle/misc/setbits64.cocci
sed -i 's,writel,writeq,' scripts/coccinelle/misc/setbits64.cocci
