[U-Boot] [PATCH v1 04/18] board: gdsys: Configure DP501 SPDIF input

[Dirk Eibach]

Hello Heiko,

2015-10-28 12:25 GMT+01:00 Heiko Schocher <hs@denx.de>:
> Hmm... a lot of magical values ... some defines would be nice here.

Agreed. Documenting all the ugly mess Parade Technologies calls an
interface would result in a list of enums, that would be as long as
(at  least) the driver itself. So I decided to comment line by line
what happens. Since this is (at least as far I as know) the only open
source code for DP501, I hope one day I will find some time to invest
some more effort here.

Cheers
Dirk

[U-Boot] [PATCH v1 05/18] board: gdsys: Increase DP501 I2C retry interval

[dirk.eibach at gdsys.cc]

From: Dirk Eibach <dirk.eibach@gdsys.cc>

With Club 3D dual link adapter there are AUX-channel timeouts
when EDID is read. Increasing retry interval time to max (400us)
fixes this.

except the same comment as patch before ... this file uses
a lot of magic values ... maybe this should be fixed?

Hmm... and converting the hole board support to DM would be nice ;-)

bye,

[U-Boot] [PATCH v1 11/18] mpc83xx: Add strider board

[dirk.eibach at gdsys.cc]

From: Dirk Eibach <dirk.eibach@gdsys.cc>

The gdsys strider board is based on a Freescale MPC8308 SOC.
It boots from NOR-Flash, kernel and rootfs are stored on
SD-Card.

On board peripherals include:
- 1x 10/100 Mbit/s Ethernet (optional)
- Lattice ECP3 FPGA connected via eLBC

[U-Boot] [PATCH v1 12/18] hrcon: Use generic ioep-fpga support

[dirk.eibach at gdsys.cc]

From: Dirk Eibach <dirk.eibach@gdsys.cc>

The strider platform moved some generic code into ioep-fpga.c.
Make use of that on hrcon platform.

[U-Boot] [PATCH v1 13/18] hrcon: Fix videoboard i2c setup

[dirk.eibach at gdsys.cc]

From: Dirk Eibach <dirk.eibach@gdsys.cc>

- i2c addresses for the videoboard port expanders were
  wrong.
- the fpga reset signal was not initialized.

[U-Boot] [PATCH v1 18/18] i2c: soft_i2c: Fix bus indizes

[dirk.eibach at gdsys.cc]

From: Dirk Eibach <dirk.eibach@gdsys.cc>

Since busses are sorted in alphabetical order, introducing more
than nine busses led to unexpected behaviour.

Would this be a good opportunity to convert these boards over to
driver model for I2C?

I'd love to, devicetrees are already there. But I am still working on
a concept to deploy this on *all* our boards and not only for I2C. So
please remain patient, I think this will be for the next merge window.
