I believe the offset for UCC3 is wrong. The usermanual says UCC3's
registers are at 0x2200-0x23FF. 0x4000 is SDMA. Hope that helps.
Looks like that was it (not sure where I got that value from!)
Thanks

Subject: UCC interactions
I'm running 2.6.33.3 on MPC8358. I have UCC1+UCC2 working fine
for ethernet, but when I add UCC3 as a UART, the network devices
quit working.
Here are my device tree entries:
/* ETH0 (UCC1, MDIO 0x02, RMII) */
enet_eth0: ether...@2000 {
device_type = "network";
compatible = "ucc_geth";
cell-index =<1>;
reg =<0x2000 0x200>;
interrupts =<32>;
interrupt-parent =<&qeic>;
local-mac-address = [ 00 00 00 00 00 00 ];
rx-clock-name = "none";
tx-clock-name = "clk16";
phy-handle =<&phy_eth0>;
phy-connection-type = "rmii";
pio-handle =<&pio_ucc1>;
linux,network-index =<0>;
};
/* ETH1 (UCC2, MDIO 0x01, GMII) */
enet_eth1: ether...@3000 {
device_type = "network";
compatible = "ucc_geth";
cell-index =<2>;
reg =<0x3000 0x200>;
interrupts =<33>;
interrupt-parent =<&qeic>;
local-mac-address = [ 00 00 00 00 00 00 ];
rx-clock-name = "clk4";
tx-clock-name = "none";
fixed-link =<1 1 1000 0 0>;
phy-connection-type = "gmii";
pio-handle =<&pio_ucc2>;
linux,network-index =<1>;
};
/* ttyQE0 (UCC3) */
serial_qe0: ser...@4000 {
device_type = "serial";
compatible = "ucc_uart";
cell-index =<3>;
reg =<0x4000 0x200>;
interrupts =<34>;
interrupt-parent =<&qeic>;
port-number =<0>;
rx-clock-name = "brg1";
tx-clock-name = "brg1";
};
Are there known interactions between these two drivers/ports?
Maybe there's something obviously wrong with my device tree?
Thanks for any ideas/pointers
