[PATCH 2/5] ARM: BCM5301X: Specify USB controllers in DT

[Rafał Miłecki]

From: Rafał Miłecki <rafal-g1n6cQUeyibVItvQsEIGlw@public.gmane.org>

There are 3 separated controllers, one per USB /standard/. With PHY
drivers in place they can be simply supported with generic drivers.

Your label ohci@21000 does not match the 'reg' at 0x22000.

Looks like you got the label of ohci and ehci reversed?

Nice catch, thanks! I'll fix it in V2 (just let me wait a day to see
if there will be other comments).

In V2, please remember to put the nodes in ascending order based on the
base address of the registers, i.e., ehci@21000, and then followed by
ohci@22000.

[PATCH 4/5] ARM: BCM5301X: Specify all RAM by including extra block

[Rafał Miłecki]

From: Rafał Miłecki <rafal-g1n6cQUeyibVItvQsEIGlw@public.gmane.org>

So far we were specifying only the first block which is always limited
up to 128 MiB. There are many devices with 256 MiB and few with 512 MiB.

Re: [PATCH 4/5] ARM: BCM5301X: Specify all RAM by including extra block

Assuming that NS is like NSP (and I'm pretty sure it is), there are 2
ways to access the first 128M of RAM, a proxy starting at address 0
and the real address.  I think you are splitting RAM by accessing it
both ways, when you really should just be accessing it at the real
address.

Thanks,
Jon

I need some more help, please.

This patch (quite well tested) confirms that 0x88000000 can be used to
access RAM at offset 128 MiB. If this is a real address and whole
space is contiguous, it means the base real address should be
0x80000000. So using 0x0 and 0x80000000 should allow accessing
beginning of the RAM. I took a device that was working just fine with:
reg = <0x00000000 0x08000000>;
and I replaced it with:
reg = <0x80000000 0x08000000>;
but it broke things, kernel didn't boot with the last message being:
[    0.000000] Memory policy: Data cache writealloc

I can see that bcm958525er.dts, bcm958525xmc.dts, bcm958623hr.dts,
bcm958625k.dts bcm988312hr.dts are using 0x60000000 as base address.
It seems to be different from Northstar but I tried following entry
anyway:
reg = <0x60000000 0x08000000>;
and I got kernel hang just like in the previous try.

Did I miss something? Or does Northstar seem to be actually different than NSP?

Per the BCM5301X Preliminary Programmer's Register Reference guide
(page 394), under the second titled "System Address Mapping".
There is a table listing the System Address Mapping.  The parts that
are of interest in this converstation are (and forgive my
approxmiation, but I cannot cut'n'paste from it):

Address Range                Size            Description
---------------------------------------------------
0x0000_0000-0x07FF_FFFF    128 MB       DDR2/3 SDRAM Memory Region*
0x8000_0000-0xBFFF_FFFF    1 G          DDR2/3 SDRAM Large Region

* The DDR2/3 SDRAM Memory Region (128MB) is a subset of the DDR2/3
SDRAM Large Region (1GB).  Additionally, 0x0000_0000-0x07FF_FFFF is
aliased to 0x8000_0000-0x87FF_FFFF

However, since you say it isn't working for you, then there must be
some other missing peice.  I'll retract my comment for now, and
hopefully we can double back and get it working in the future.

Thanks,
Jon

[PATCH 5/5] ARM: BCM53573: Specify USB ports of on-SoC controllers

[Rafał Miłecki]

From: Rafał Miłecki <rafal@milecki.pl>

Broadcom OHCI and EHCI controllers always have 2 ports each on the root
hub. Describe them in DT to allow specifying extra info or referencing
port nodes.
