ARM: shmobile: r8a73a4 APE6EVM board support (V3)
[PATCH 01/03 v2] ARM: shmobile: APE6EVM base support
[PATCH 02/03 v2] ARM: shmobile: APE6EVM PFC support
[PATCH 03/03 v2] ARM: shmobile: APE6EVM LAN9220 support
This series is V3 of initial support for the APE6EVM board.
The APE6EVM board makes use of the r8a73a4 SoC and has a
couple of different I/O devices on board, but with this
series only support for the SCIFA0 UART and the Ethernet
chip is included.
In the future support for more I/O devices will be added as
incremental feature patches.
Changes since V2:
- Use PINCTRL instead of function GPIOs.
- Modify bootargs to enable DHCP and NFS root.
- Now depends on r8a73a4 PFC V2
Changes since V1:
- Went from single patch to series
- Use ape6evm_add_standard_devices() to setup SoC devices and clocks
- Use PFC to configure SCIFA0
- Add Ethernet support including PFC support
For more details please see the individual patches.

From: Magnus Damm <damm@opensource.se>
Add LAN9220 support to the APE6EVM board using C and DT.
At this point the PFC driver lacks DT bindings so to
configure the PFC we use PINCTRL in C board code.
Signed-off-by: Magnus Damm <damm@opensource.se>

Changes since V1:
- Use PINCTRL instead of function GPIOs.
- Modify bootargs to enable DHCP and NFS root.

From: Magnus Damm <damm@opensource.se>
Add LAN9220 support to the APE6EVM board using C and DT.
At this point the PFC driver lacks DT bindings so to
configure the PFC we use PINCTRL in C board code.
Signed-off-by: Magnus Damm <damm@opensource.se>
---
Changes since V1:
- Use PINCTRL instead of function GPIOs.
- Modify bootargs to enable DHCP and NFS root.

Thanks Magnus,
I have no outstanding concerns with these patches.
Let me know if/when you would like them queued-up for v3.10.

and configure the SCIFA0 console signals in the
PFC via PINCTRL.
