[PATCH 4.5 66/88] ARM: dts: apq8064: add ahci ports-implemented mask

From: Greg Kroah-Hartman
Date: Mon May 09 2016 - 03:41:35 EST


4.5-stable review patch. If anyone has any objections, please let me know.

------------------

From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx>

commit bb4add2ce991e4ec891b5a0287fd1ab77b631979 upstream.

This patch adds new ports-implemented mask, which is required to get
achi working on the mainline. Without this patch value read from
PORTS_IMPL register which is zero would not enable any ports for
software to use.

Fixes: 566d1827df2e ("libata: disable forced PORTS_IMPL for >= AHCI 1.3")
