2019-05-21arm64: dts: meson: nanopi k2: add sd DDR50Jerome Brunet
Add UHS ddr50 mode to the nanopi k2 Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2019-05-21arm64: dts: meson: fix mmc v2 chips max frequenciesJerome Brunet
According the datasheets, emmc v2 chips (gxbb and gxl) don't support more that 100Mhz in UHS-1 SD modes and HS in SDIO. Align the max-frequency to 100MHz for UHS-1 and 50MHz for HS Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2019-01-14arm64: dts: meson: Fix mmc cd-gpios polarityLoys Ollivier
Commit 89a5e15bcba8 ("gpio/mmc/of: Respect polarity in the device tree") changed the behavior of "cd-inverted" to follow the device tree bindings specification: According to SDHCI standard, CD lines are specified as "active low". Using the "cd-inverted" property means that the CD line is "active high". Fix the SD card description for meson by setting the cd-gpios as "active low", according to the boards specifications, and dropping the "cd-inverted" property.

2018-11-29arm64: dts: meson-gxbb-nanopi-k2: fix GPIO lines namesNeil Armstrong
The gpio line names were set in the pinctrl node instead of the gpio node, at the time it was merged, it worked, but was obviously wrong. This patch moves the properties to the gpio nodes.

2018-07-20ARM64: dts: meson-gxbb-nanopi-k2: Add HDMI, CEC and CVBS nodesNeil Armstrong
The Amlogic Meson GXBB based Nanopi-K2 board has an HDMI connector with CEC and CVBS available on the 40pin header. This patch adds the nodes to enable HDMI, CEC and CVBS functionnalities. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>

2018-02-12ARM64: dts: meson: accept MAC addr from u-boot environmentJorge Ramirez-Ortiz
Extend configuring the MAC address from u-boot to all meson boards. I didn't test this changeset but having checked libretech's u-boot tree I believe it should just work. Signed-off-by: Jorge Ramirez-Ortiz <jramirez@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
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>
2017-10-29ARM64: dts: meson-gx: add external PHY interrupt on some platformsJerome Brunet

2017-10-11ARM64: dts: meson-gxl: Take eMMC data strobe out of eMMC pinsNeil Armstrong
Since the Data Strobe pin is optional, take it out of the default eMMC pins and add a separate entry. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Tested-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2017-10-11ARM64: dts: meson-gxbb: adjust nanopi-k2 gpio-line-namesJerome Brunet
GPIOX22 is now declared properly and TEST_N has been moved so the gpio-line-names of the nanopi-k2 must be adjusted accordingly Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>

2017-09-05ARM64: dts: meson-gxbb: nanopi-k2: add card regulator settle timesJerome Brunet
Changing the card voltage on the nanopi-k2 is not instantaneous, especially when switching from 3.3v to 1.8v. It take at least 3ms for the regulator to go from 3.3v to 1.8v. Add margin to that to make sure we don't upset the sdcard during the voltage switch Fixes: 9bc7ffb08daf ("arm64: dts: amlogic: Add NanoPi K2") Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
