Given this defines part of the binding, it should probably go in the
same patch.
Cheers,
Mark.

Hi Kishon,
Here is the MiPHY365x patchset complete with all the DT Acks applied.
This set has been on the list for ~10 weeks now with no further comments.
Would you be kind enough to merge the PHY patches/documentation please?
Kind regards,
Lee

The MiPHY365x is a Generic PHY which can serve various SATA or PCIe
devices. It has 2 ports which it can use for either; both SATA, both
PCIe or one of each in any configuration.

+STMicroelectronics STi MIPHY365x PHY binding
+============================================
+
+This binding describes a miphy device that is used to control PHY hardware
+for SATA and PCIe.
+
+Required properties:
+- compatible : Should be "st,miphy365x-phy"
+- #phy-cells : Should be 2 (See second example)
+ First cell is the port number from:
+ - MIPHY_PORT_0
+ - MIPHY_PORT_1
+ Second cell is device type from:
+ - MIPHY_TYPE_SATA
+ - MIPHY_TYPE_PCI
+- reg : Address and length of register sets for each device in
+ "reg-names"
+- reg-names : The names of the register addresses corresponding to the
+ registers filled in "reg", from:
+ - sata0: For SATA port 0 registers
+ - sata1: For SATA port 1 registers
+ - pcie0: For PCIE port 0 registers
+ - pcie1: For PCIE port 1 registers
+- st,syscfg : Should be a phandle of the system configuration register group
+ which contain the SATA, PCIe mode setting bits
+
+Optional properties:
+- st,sata-gen : Generation of locally attached SATA IP. Expected values
+ are {1,2,3). If not supplied generation 1 hardware will
+ be expected
+- st,pcie-tx-pol-inv : Bool property to invert the polarity PCIe Tx (Txn/Txp)
+- st,sata-tx-pol-inv : Bool property to invert the polarity SATA Tx (Txn/Txp)
+
+Example:
+
+ miphy365x_phy: miphy365x at fe382000 {
+ compatible = "st,miphy365x-phy";
+ #phy-cells = <2>;
+ reg = <0xfe382000 0x100>,
+ <0xfe38a000 0x100>,
+ <0xfe394000 0x100>,
+ <0xfe804000 0x100>;
+ reg-names = "sata0", "sata1", "pcie0", "pcie1";
+ st,syscfg = <&syscfg_rear>;
+ };
+
+Specifying phy control of devices
+=================================
+
+Device nodes should specify the configuration required in their "phys"
+property, containing a phandle to the miphy device node, a port number
+and a device type.
+
+Example:
+
+#include <dt-bindings/phy/phy-miphy365x.h>
+
+ sata0: sata at fe380000 {
+ ...
+ phys = <&miphy365x_phy MIPHY_PORT_0 MIPHY_TYPE_SATA>;
+ ...
+ };

The MiPHY365x is a Generic PHY which can serve various SATA or PCIe
devices. It has 2 ports which it can use for either; both SATA, both
PCIe or one of each in any configuration.

Kishon,
Did you receive this set okay? I believe it's still unmerged?

I think I missed it. But I'm already done with the PULL REQUEST to greg for
3.16 merge window.
Can't we take it through dt tree for miphy?
Thanks

Really, already? It's only -rc5?

Well there are 3 patches. 2 of which could go through your DT tree,
but the 3rd one is the driver itself.

I think it is, as you introduce a new board.
Moreover, the miphy description being the same as in stih416-b2020.dts,
so I don't understand why you introduce this board for this feature.

Introducing an empty dts file just so you can say "this is a new
board" seems odd to me, but I'll go with whatever you feel it right.

It's historical. There are other differences between rev-E and the
other reversions, such as; gpio-leds (red, green) and the reset GPIO
for ethernet. As these are dts files (rather than dtsi) files, you
can only use one at a time.

My point was to create a new patch that would also introduce the
differences (Ethernet, leds...). The commit message would explain the
differences versus stih416-b2020.
From your patch, if I didn't know the differences, I would ask why you
don't use stih416-b2020.dts.
If you have another pending patch that make Ethernet to work on revE
board, you can keep this one as it is.

This provides the shared header file which will be reference from both
the MiPHY365x driver and its associated Device Tree node(s).

No need to have parens around macros but you should instead enclose the
'|' operator and its arguments into parens.
