2019-06-25ARM: dts: uniphier: update to new Denali NAND bindingMasahiro Yamada1-0/+4
With commit d8e8fd0ebf8b ("mtd: rawnand: denali: decouple controller and NAND chips"), the Denali NAND controller driver migrated to the new controller/chip representation. Update DT for it. In the new binding, the number of connected chips are described in DT instead of run-time probed. I added just one chip to the reference boards, where we do not know if the on-board NAND device is a single chip or multiple chips. If we added too many chips into DT, it would end up with the timeout error in nand_scan_ident(). I changed all the pinctrl properties to use the single CS.

2018-10-03ARM: dts: uniphier: add SD/eMMC controller nodesMasahiro Yamada1-0/+4
Add SD controller nodes for LD4, Pro4, sLD8, Pro5, and PXs2. This is also used as an eMMC controller for LD4, Pro4, and sLD8. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-03-15ARM: dts: uniphier: use proper SPDX-License-Identifier styleMasahiro Yamada1-8/+6
According to Documentation/process/license-rules.rst, move the SPDX License Identifier to the very top of the file. I used C++ comment style not only for the SPDX line but for the entire block because this seems Linus' preference [1]. I also dropped the parentheses to follow the examples in that document.

2017-12-11ARM: dts: uniphier: use macros in dt-bindings headerMasahiro Yamada1-1/+1
The dt-bindings header was applied to the driver subsystem. I had to wait for a merge window to use it from DT. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-10-23ARM: dts: uniphier: add GPIO hog definitionMasahiro Yamada1-0/+8
Interrupt lines from on-board devices are connected to the GPIO controller. Add GPIO hogging so that the corresponding GPIO line is automatically requested. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-10-23ARM: dts: uniphier: route on-board device IRQ to GPIO controllerMasahiro Yamada1-1/+1
Interrupt lines from on-board devices are connected to the GPIO controller. Handle this correctly. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-08-15ARM: dts: uniphier: add Denali NAND controller nodeMasahiro Yamada1-0/+4
Add NAND controller node to LD4, Pro4, sLD8, Pro5, and PXs2. Set up pinctrl to enable 2 chip select lines except Pro4. The CS1 for Pro4 is multiplexed with other peripherals such as UART2, so I did not enable it. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-08-15ARM: dts: uniphier use #include instead of /include/Masahiro Yamada1-3/+3
To include dt-bindings headers. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Follow the recent trend for the license description, and fix the wrongly stated X11 to MIT. The X11 license text [1] is explicitly for the X Consortium and has a couple of extra clauses. The MIT license text [2] is actually what the current DT files claim.

2017-03-11ARM: dts: uniphier: move memory node below aliases nodeMasahiro Yamada1-5/+5
These UniPhier DT files are fine as long as they are compiled in the Linux build system. It is true that Linux is the biggest user of DT, but DT is project neutral from its concept. DT files are often re-used for other projects. Especially for the UniPhier platform, these DT files are re-used for U-Boot as well. If I feed these DT files to the FDTGREP tool in U-Boot, it complains about the node order. FDTGREP spl/u-boot-spl.dtb Error at 'fdt_find_regions': FDT_ERR_BADLAYOUT /aliases node must come before all other nodes Given that DT is not very sensitive to the order of nodes, this is a problem of FDTGREP. I filed a bug report a year ago, but it has not been fixed yet. Differentiating DT is painful. So, I am up-streaming the requirement from the down-stream project.

2017-03-06ARM: dts: uniphier: fix no unit name warningsMasahiro Yamada1-1/+1
Fix warnings reported when built with W=1: Node /memory has a reg or ranges property, but no unit name Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-08-30ARM: dts: uniphier: match DT names to other projects and documentsMasahiro Yamada1-0/+102
All UniPhier device trees have the common prefix "uniphier-", so "ph1-" is just making names longer. Recent documents and other projects are not using PH1- prefixes any more. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
