From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ying.Liu@freescale.com (Liu Ying) Date: Fri, 4 Jul 2014 17:00:41 +0800 Subject: [PATCH] bus: imx-weim: populate devices on a simple bus Message-ID: <1404464441-31755-1-git-send-email-Ying.Liu@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org There could be some memory map devices located in a certain chip select region of the i.MX WEIM. The devices could be attached to a simple bus(for example, a AXI bus) whose root node is one child device tree node of the i.MX WEIM device tree node. There should be a bridge(very likely, software transparent) bewteen the i.MX WEIM and the simple bus. This patch makes the i.MX WEIM driver possible to populate devices on a simple bus. In this way, people may try various IPs(in a FPGA, maybe) outside of i.MX chips with the i.MX WEIM embedded.
