[PATCH v7 0/9] Add MPC837x generic support and MPC837xE MDS support

[PATCH v7 0/9] Add MPC837x generic support and MPC837xE MDS support

[Li Yang]

Also includes a patch cleaning up IPIC, which could improve the performance.
Hope this is the lucky version with the acceptable DTS's.

+    SATA nodes are defined to describe on-chip Serial ATA controllers.

+
+    - compatible : Should specify what this SATA controller is compatible
+      with.
+    - reg : Offset and length of the register set for the device.
+    - interrupts : <a b> where a is the interrupt number and b is a
+      field that represents an encoding of the sense and level
+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt
+      controller you have.
+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+
+    Recommended properties :
+
+    - phy-handle : Some SATA controller uses a shared SerDes PHY. This
+      property should specify the phandle of the SerDes node.
+
+   Example:
+
+	sata@19000 {
+		compatible = "fsl,mpc8315-sata";
+		reg = <19000 1000>;
+		interrupts = <2d 8>;
+		interrupt-parent = < &ipic >;
+		phy-handle = < &serdes1 >;
+        };

    More devices will be defined as this spec matures.

+    SerDes is a serializer/deserializer used by some Freescale SoC.
+
+    Required properties:
+
+    - compatible : Should specify what this SerDes controller is compatible
+      with.  Currently, this is most likely to be "fsl,serdes".

+    - clock : Input clock frequency for SerDes in unit of MHz.
+
+    Optional properties:
+
+    - vdd-1v : Define this property when Vdd is 1V.
+    - pcie-x2 : Define this property when using PCI Express x2 interface.
+      Valid only when protocol is set to "pcie".
+
+   Example:

[PATCH v7 7/9] ipic: clean up unsupported ack operations

[Li Yang]

IPIC controller doesn't support ack operations.  The pending registers
are read-only.  The patch removes ack operations which are not needed.

Hi Kumar,

Please hold on this one.  Actually external interrupts in edge mode need
this ack operation.  But in most cases (level triggered) ack is not
needed.  I will provide an updated patch later on to take care both
trigger modes.  Thanks.

I'm not sure about this property.  Does the driver need to know about
this?  Will this setup ever change at runtime?  It seems to me that
like GPIOs and chip selects, setting you which shared PHY goes with
which device is something that should be done at board setup time.

Re: [PATCH v7 3/9] add Freescale SerDes PHY support

This looks like board setup behaviour.  Shouldn't setting this up be
the responsibility firmware?  And failing that, I think it should be
done directly by the platform setup function (in other words; make it
a helper function and call it at board setup time).  Besides, you want
to provide guarantees that the board is setup correctly before the
device driver that uses it gets probed.

Cheers,

Upon further review of all this I don't think this belongs in the  
kernel at all.  This is one time setup and should be done in firmware.

The latest u-boot supports the serdes initialization for 837x.
So, it can be dropped from kernel for now.

I'm ok for it to be taken care of in u-boot for now.  However, if we
later plan to add power management support to this block.  We probably
have to do it in kernel.

How does pwr mgmt come into play w/SerDes?

Never mind, if we do add pwr mgmt it looks like all we need to know is  
what SerDes is associated with the device.

In that case, can't it be just saving/restoring ? That's easier than
supporting full configuration of random user setups
