From mboxrd@z Thu Jan 1 00:00:00 1970 From: antoine.tenart@free-electrons.com (Antoine Tenart) Date: Thu, 15 Oct 2015 09:17:31 +0200 Subject: [PATCH v3 4/4] mtd: pxa3xx_nand: clean up the pxa3xx timings In-Reply-To: <1444893451-16610-1-git-send-email-antoine.tenart@free-electrons.com> References: <1444893451-16610-1-git-send-email-antoine.tenart@free-electrons.com> Message-ID: <1444893451-16610-5-git-send-email-antoine.tenart@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org With the previous modifications, lots of pxa3xx specific definitions can be removed.
