2019-06-19arm64: dts: meson: use the generic Ethernet PHY reset GPIO bindingsMartin Blumenstingl
The snps,reset-gpio bindings are deprecated in favour of the generic "Ethernet PHY reset" bindings. Replace snps,reset-gpio from the &ethmac node with reset-gpios in the ethernet-phy node. The old snps,reset-active-low property is now encoded directly as GPIO flag inside the reset-gpios property. snps,reset-delays-us is converted to reset-assert-us and reset-deassert-us. reset-assert-us is the second cell from snps,reset-delays-us while reset-deassert-us was the third cell. Instead of blindly copying the old values (which seems strange since they gave the PHY one second to come out of reset) over this also updates the delays based on the datasheets: - the Realtek RTL8211F PHY needs a 10ms assert delay (the datasheet mentions: "For a complete PHY reset, this pin must be asserted low for at least 10ms") and a 30ms deassert delay (the datasheet mentions: "Wait for a further 30ms (for internal circuits settling time) before accessing the PHY register". This applies to the following boards: GXBB NanoPi K2, GXBB Odroid-C2, GXBB Vega S95 variants, GXBB Wetek variants, GXL P230, GXM Khadas VIM2, GXM Nexbox A1, GXM Q200, GXM RBox Pro boards. - the ICPlus IP101GR PHY needs a 10ms assert delay (the datasheet mentions: "Trst | Reset period | 10ms") and a deassert delay of 10ms as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock output ready after reset released | 10ms"). This applies to the GXBB Nexbox A95X board. - the Micrel KSZ9031 seems to require a 100us delay but use the same (seemingly safe) values from RTL8211F due to lack of a board to verify this. This applies to the GXBB P200 board. The GXBB P201 board is left out from this conversion because it doesn't have a dedicated PHY node (because it's not clear which PHY is used on that board).

2019-05-21arm64: dts: amlogic: remove ethernet-phy-idAAAA.BBBB compatible stringsMartin Blumenstingl
The Ethernet PHY documentation (Documentation/devicetree/bindings/net/phy.txt) states that: If the PHY reports an incorrect ID (or none at all) then the "compatible" list may contain an entry with the correct PHY ID in the form: "ethernet-phy-idAAAA.BBBB" An older version of the documentation suggested that the compatible string can be used when the PHY ID is known. Remove the ethernet-phy-id compatible string and add a comment with the PHY ID instead. This is a no-op on boards which are shipped with the PHY that was listed (= all known cases). However, if a board manufacturer decides to ship a different PHY we will now load and use the correct driver because we ask the PHY to identify itself.

2018-07-20ARM64: dts: meson-gx-p23x-q20x: move the wifi node to each board's .dtsMartin Blumenstingl
meson-gx-p23x-q20x.dtsi is currently used by five boards: - Amlogic P230 and P231 (which should be identical, apart from the external RGMII PHY on P230 whereas P231 can only use the internal PHY) - Amlogic Q200 (identical to P230 but with an S912 GXM SoC instead of a GXL S905D SoC) and Q201 (identical to P231 but with an S912 GXM SoC instead of a GXL S905D SoC) - NEXBOX A1 (based on the S912 GXM SoC) The Amlogic P230 board uses a Broadcom BCM4356 SDIO wifi chip. Since the other Amlogic reference design boards are very similar it's safe to assume that these also use a Broadcom based SDIO wifi chip (which is also how it was configured in meson-gx-p23x-q20x.dtsi). However, NEXBOX A1 comes with a "longsys LTM8830" SDIO wifi module, which is based on the "Qualcomm Atheros QCA9377-3(QCA1023-0)" chipset. Thus move the wifi node from meson-gx-p23x-q20x.dtsi to each of the four Amlogic reference board's .dts files. There are no devicetree bindings for the QCA9377 SDIO wifi module yet, so nothing is added to meson-gxm-nexbox-a1.dts.

2018-07-20ARM64: dts: meson: enable the saradc node in meson-gx-p23x-q20x.dtsiMartin Blumenstingl
meson-gxl-s905d-p230.dts and meson-gxm-q200.dts enable the saradc node (and configure it's vref-supply "VDDIO_AO18") in their corresponding .dts file. Move both (the saradc node as well as the VDDIO_AO18 regulator) to remove some duplicate code. As a positive side-effect this enables the saradc also for the P231 (GXL S905D) and Q201 (GXM S912) development boards which are similar to the P230/Q200 boards (P231 and Q201 use the internal 100Mbit/s PHY, while P230 and Q200 have an external RGMII PHY).

2017-12-08ARM64: dts: meson: add comments with the GPIO for the PHY interruptsMartin Blumenstingl
Currently one has to look/calculate the GPIO for the PHY interrupts manually. Add a comment for the existing PHY interrupt lines to make it easier to find out which GPIO is used. This is done using the following calculation: - number of GPIO AO pins (14 on GXBB: GPIOAO_0..13) - add the offset of the pin which is used for the interrupt (for example GPIOZ_15 = 15 on Odroid-C2) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Reviewed-By: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
