Currently, the only 6282-based Kirkwood boards that use I2C1 are Openblocks A6/A7. Both use the same default I2C1 pinctrl setting from kirkwood-6282.dtsi. Move the pinctrl setting to the I2C1 node directly and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Signed-off-by:

There is only one valid pinctrl setting for I2C0 on Kirkwood. Now that we have the setting in the common SoC pinctrl, move it to the I2C0 controller node directly and remove it from the individual boards. While at it, also fix up status = "okay" to "ok" on one board's I2C0 node. Signed-off-by:

There is only one valid pinctrl setting for NAND on Kirkwood. Now that we have the setting in the common SoC pinctrl, move it to the NAND controller node directly and remove it from the individual boards. While at it, also fix up status = "okay" to "ok" on one board's NAND node. Signed-off-by:

Most Kirkwood boards use the default SPI0 pinctrl setting anyway. Add a default pinctrl setting to the toplevel SoC SPI0 node and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Currently, only T5325 is using a different setting and already overwrites the corresponding pinctrl node. Signed-off-by:

Most boards use the default UART0/1 pinctrl setting without RTS/CTS. Add the pinctrl setting to the toplevel SoC UART nodes and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Currently, both boards using a different UART pinctrl setting (Openblocks A6, A7) already overwrite the pinctrl node. While at it, also fix up some status = "ok" to "okay" and again whitespace issues on mplcec4 uart nodes. Signed-off-by:

All Kirkwood SoCs have their pinctrl registers at the same address. Instead of replaying the same reg property on each SoC, have the reg property set in the common SoC file already. This also allows us to move common pinctrl settings to this node later on. Signed-off-by:

UART devices found on Kirkwood SoCs derive their baudrate from TCLK. With proper clocks property in the SoCs serial node, boards do not need to overwrite it anymore. Remove the remaining clock-frequency property from all Kirkwood boards. Signed-off-by:

ePAPR allows to reference the device used for console output by stdout-path property. With node labels for Kirkwood UART0, now reference it on all Kirkwood boards that already have ttyS0 in their bootargs property. While at it, fix some whitespace issues on mplcec4's chosen node (there are more, but we only fix the chosen node now) Signed-off-by:

This adds missing node labels to Kirkwood common and SoC specific nodes to allow to reference them more easily. Signed-off-by:

The Netgear RN2120 was not using the same strategy as the other Armada 370/375/38x/XP boards: it was using a 'clocks' property and not the 'clock-frequency' property in its UART controller Device Tree node. However, now that this clock reference is present at the SoC-level, there is no point in duplicating it at the board-level. Signed-off-by:

Now that the Armada 370/375/38x/XP SoC-level Device Tree files have the proper "clocks" property in their UART controllers node, it is no longer useful to have the clock-frequency property defined in the board-level Device Tree files. Therefore, this commit gets rid of all the useless 'clock-frequency' properties. Signed-off-by:

Thomas Petazzoni authored
Back when the Armada 370 and Armada XP initial support was introduced, the only way to pass the clock frequency to the of_serial driver was through a clock-frequency Device Tree property. Thanks to 0bbeb3c3 ('of serial port driver - add clk_get_rate() support'), it is possible to use the standard 'clocks' DT property to reference the clock used for a particular UART controller. This clock is then used by the of_serial driver to retrieve the clock rate. This commit modifies the SoC-level Device Tree files of Armada 370, Armada XP, Armada 375 and Armada 38x to use this possibility. Since there is no gatable clock for the UART controllers, we simply reference the TCLK, which is the main SoC clock for the peripherals. Signed-off-by:

In commit "mmc: sdhci-pxav3: add support for the Armada 38x SDHCI controller", the sdhci-pxav3 driver has been extended to also be usable on Armada 38x platforms. Therefore, this commit adds the necessary Device Tree informations to declare this SDHCI interface in the Armada 38x SoC, and also in the Armada 385 Development Board. Signed-off-by:

Following the introduction of the new PMSU Device Tree binding, as well as the separate CPU reset binding, this commit switches the Armada 370 and Armada XP Device Trees to use them. The PMSU node is moved from the Armada XP specific armada-xp.dtsi to the common Armada 370/XP armada-370-xp.dtsi because the PMSU is in fact available at the same location on both SOCs. The CPU reset node is then added on both Armada 370 and Armada XP, with a different compatible string. On Armada 370, the CPU reset driver is not really needed as Armada 370 is single core and the only use of the CPU reset driver is to boot secondary processors, but it still makes sense to have this CPU reset register described in the Device Tree.
