Hi,
I am currently developing a custom board based on the AM1808 SoC. On
this board the SoC is driven by a 25 MHz oscillator. For the board I
created a board configuration file, e.g.,
arch/arm/mach-davinci/board-xyz.c However, the SoC specific file
arch/arm/mach-davinci/da850.c assumes that the

Hi again,
how about this solution? I just took a look how this is solved on other
ARM platforms.

From Mike Williamson [mailto:michael.william...@criticallink.com]
It seems to me if you alter the reference clock rate you'll need to
ensure that CONFIG_CPU_FREQ is turned off as all the OPP's in da850.c
are based on a 24 MHz oscillator input. To support CONFIG_CPU_FREQ with
a variable input

This approach looks good
to the board
specific files to support boards with oscillator/crystal frequencies other
than 24 MHz.

I am not sure if it correctly fixes the problem

Hi,
I observed this behavior on a Texas Instruments AM1808 SoC (AM1808
experimenter's kit) running the current mainline kernel:
# ifconfig eth0 down
# ifconfig eth0 up
davinci_mdio davinci_mdio.0: resetting idled controller
net eth0: attached PHY driver [Generic PHY]
reported
by ifconfig is counting up.
This patch reverts commit 0a5f38467765ee15478db90d81e40c269c8dda20
and instead issues warnings only if cpdma_chan_submit returns -ENOMEM.
