Problem porting driver for OTP cells on Freescale i.MX28

Problem porting driver for OTP cells on Freescale i.MX28

[Christoph]

Hello list,

currently I'm porting some drivers from the Freescale SDK based on 2.6.35 for
the i.MX28 to 3.7+ .
Working on the OTP eFuses I ran into a problem concerning clock sources. The OTP
driver requires to change the clock frequency of some logic blocks when writing
to OTP cells. In the original code from Freescale it requested "hclk" via
clk_get(). As this seems to be named "hbus" in the vanilla kernels I changed
this, but still clk_get() fails.
My patch can be found at http://www.sgoc.de/Downloads/fsl-otp.patch (NOTE: It
contains some printk for debugging and as stated above writing does not work).
Are there any hints on the clock API?



Regards,
Christoph Baumann

AT91SAM9M10: Problem porting driver for MT9P031 sensor

[Marcio Campos de Lima]

Hi

I am porting the MT9P031 sensor device driver for a custom designed board
based at the AT91SAM9M45-EK development board and Linux 3.6.9.
The driver detects the sensor but does not create /dev/video1. I cannot
even see /dev/video0 that usually is created by default.

Can anybody help me?
Thanks
MArcio

You might get better luck if you push your code somewhere
so people can take a look at it.

Also, IMHO the arm mailing list is not the best place to ask
try asking the media ML: linux-media _at_ vger.kernel.org
and #v4l at freenode IRC.

Good luck!
