Subject: Where in dts file one should define IORESOURCES_(IO|MEM)?
Date: Mon, 13 Apr 2009 10:52:52 -0700 [thread overview]
Message-ID: <003e01c9bc60$ab11c2c0$9e70150a@cisco.com> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 898 bytes --]
I have read the Documentation/powerpc/booting-without-of.txt and I am still
not clear on how manifest constants in platform_get_resource() get
translated to items in dts file.
Example:
in drivers/ide/legacy/ide_platform.c there is code that looks like this.
res_base = platform_get_resource(pdev, IORESOURCE_IO, 0);
res_alt = platform_get_resource(pdev, IORESOURCE_IO, 1);
if (!res_base || !res_alt) {
res_base = platform_get_resource(pdev, IORESOURCE_MEM, 0);
res_alt = platform_get_resource(pdev, IORESOURCE_MEM, 1);
If I want to specify IORESOURCE_MEM (0) and IORESOURCE_MEM ( 1) addresses in
my board specific what statements do I need to include in my dts file?
I have tried including them in memory {} section of dts and that doesn't
work.
Would appreciate help/pointer.
