Date: Wed, 10 Aug 2016 17:37:30 +0200 From: <patrice.chotard@...com> To: Tejun Heo <tj@...nel.org>, <linux-arm-kernel@...ts.infradead.org>, <linux-ide@...r.kernel.org>, <linux-kernel@...r.kernel.org> CC: <patrice.chotard@...com>, <kernel@...inux.com> Subject: [PATCH 2/2] ARM: dts: STiH407-family: Add ports-implemented property in sata nodes From: Patrice Chotard <patrice.chotard@...com> Despite ST AHCI version = 1.3, reading HOST_PORTS_IMPL returns 0. So force HOST_PORTS_IMPL to 1 by using ports-implemented DT property.
