Hi,
we're about to get new MPC8377 based hardware with various peripherals.
There are two I2C-to-SPI bridge devices (NXP SC18IS602) and I'm not sure
how to define a proper dts...
Of course it's an easy thing creating 2 child nodes on the CPU's I2C
device - but how can I represent the created SPI

Move Freescale elbc interrupt from nand dirver to elbc driver.
Then all elbc devices can use the interrupt instead of ONLY nand.

Are you sure that you want it as a global var? A bit scary change.
Oh, you probably don't need it, as you can get it from

Hello,
I have a board with 2 PHYs attached to one FEC.
I want to implement some kind of main-standby attachment to LAN by
setting the ISOLATE bit on one on the two PHYs then monitoring the link
status and switch to the other PHY when the link status goes down.
What would be the most proper

No, it won't affect the performance. We got line rate for performance

Tighten up time timing around the gpio reset functionality. Add a 200ns
delay before remuxing the pins back to ac97 to comply with the ac97 spec.
This delay ensures that sync and sdata_out are held low while reset

Yes, but it is way more readable. Does the extra delay hurt? The value

clock frequencies?
The reset is happening in the gpio spinlock, so I am trying to keep busy
waiting to a minimum. The magic value of 7 calculates

Hello everyone,
Yesterday I asked where board specific drivers should be located in the
source tree. Several people suggested I just post the drivers for review
right away, and let the reviewers comment on where to put the drivers.
Here they are. I've created a new drivers/fpga/carma/ directory
This adds basic support for the system controller FPGA on the OVRO CARMA
board. This patch only adds infrastructure that will be used by later
drivers.

This driver allows userspace to access the data processing FPGAs on the
OVRO CARMA board. It has two modes of operation:
1) random access
This allows users to poke any DATA-FPGA registers by using mmap to map
the address region directly into their memory map.
2) correlation dumping
When
This adds support for programming the data processing FPGAs on the OVRO
CARMA board. These FPGAs have a special programming sequence that
requires that we program the Freescale DMA engine, which is only
available inside the kernel.
