* arm: dts: fix unit-address leading 0sRob Herring2017-10-201-1/+1
| | | | | | | | | | | | | Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using the following command: perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*' Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some occurrences of uppercase hex.

* ARM: dts: imx: Fix Ethernet PHY reset polarityFabio Estevam2017-06-051-1/+1
| | | | | | | | | | | | | The FEC driver ignores the GPIO polarity from 'phy-reset-gpios' and considers that the Ethernet PHY is active low, unless the property 'phy-reset-active-high' is present. Fix the device tree description by explicitly passing the 'GPIO_ACTIVE_LOW' flag to the 'phy-reset-gpios' property.

* ARM: dts: imx6qdl-wandboard: Fix audio channel swapFabio Estevam2017-05-151-0/+1
| | | | | | | | | | | | When running a stress playback/stop loop test on a mx6wandboard channel swaps can be noticed randomly. Increasing the SGTL5000 LRCLK pad strength to its maximum value fixes the issue, so add the 'lrclk-strength' property to avoid the audio channel swaps.

* ARM: dts: imx: Use generic uart-has-rtscts DT propertyGeert Uytterhoeven2016-06-111-1/+1
| | | | | | | | | | | As of commit 1006ed7e1b258dac ("serial: imx: Use generic uart-has-rtscts DT property"), the Freescale IMX UART driver recognizes the generic "uart-has-rtscts" DT property, deprecating the vendor-specific "fsl,uart-has-rtscts" DT property. Hence replace the latter by the former in all DTS files. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

| | | | | | | | | | | cd-gpios polarity should be changed to GPIO_ACTIVE_LOW and wp-gpios should be changed to GPIO_ACTIVE_HIGH. Otherwise, the SD may not work properly due to wrong polarity inversion specified in DT after switch to common parsing function mmc_of_parse().

* ARM: dts: Restructure imx6qdl-wandboard.dtsi for new rev C1 board.George Joseph2014-07-181-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The rev C1 Wandboard uses the Broadcom 4330 for WiFi and Bluetooth instead of the 4329. This changes the PADS assigned for the control lines. Another side effect of the change is that on the rev C1 board, usdhc driver can't detect the chip presence correctly so usdhc2 now needs its 'non-removeable' property removed. So that rev B1 and earlier can continue to work, this patch splits the board-specific definitions from imx6qdl-wandboard.dtsi into imx6qdl-wandboard-revb1.dtsi and imx6qdl-wandboard-revc1.dtsi. The new files include the original base imx6qdl-wandboard.dtsi which retains the common definitions. The existing imx6dl-wandboard.dts includes imx6qdl-wandboard-revc1.dtsi and imx6dl-wandboard-revb1.dts (new) includes imx6qdl-wandboard-revb1.dtsi. This makes the rev C1 board the new default. The same pattern is used for imx6q-wandboard.dts. So, from U-Boot on a WB-Quad you use imxq-wandboard-revb1.dtb for the older B1 board and imxq-wandboard.dtb for the current rev C1 board.

* ARM: dts: imx: remove ssi fsl,mode for audio cardsMarkus Pargmann2014-07-181-1/+0
| | | | | | | | | | | | | | The DAI mode is and should be configured by the sound card driver as codec and ssi have to be in the right modes to communicate with each other. It is possible to operate the ssi unit or the codec in master mode, sometimes even on the same board in different configurations. With the latest changes in the fsl-ssi driver, the 'fsl,mode' property is only handled as a fallback property. If the sound card sets the DAI mode correctly, this fallback configuration is dropped.

* ARM: dts: imx6qdl-wandboard: use GPIO_6 for FEC interruptSascha Silbe2014-02-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Apply the same work-around for i.MX 6D/Q erratum 006687 as used for Sabre Lite for the Wandboard Dual / Quad. Like on the Sabre Lite, GPIO6 is used as a power down output for camera expansion boards. However, these expansion boards do not work with mainline yet anyway. Tested on a Wandboard Quad.

* ARM: dts: imx: specify the value of audmux pinctrl instead of 0x80000000Nicolin Chen2014-02-091-4/+4
| | | | | | | | | | | | | | | | We must specify the value of audmux pinctrl if we want to use pinctrl_pm(). Thus change bypass value 0x80000000 to what we exactly need. This patch also seperately unset PUE bit for TXD so that IOMUX won't pull up/down the pin after turning into tristate. When we use SSI normal mode to playback monaural audio via I2S signal, there'd be a pulled curve occur to its signal at the second slot if setting PUE bit for TXD. And it will make the second channel to play a constant noise. So by keeping the signal level in the second slot, we can get a constant high level signal (-1) or a low level one (0).

* ARM: dts: imx6: use generic node name for fixed regulatorShawn Guo2014-02-091-2/+6
| | | | | | | | The device tree specification recommends that generic name should be used for nodes. So instead of naming those fixed regulator nodes arbitrarily, let's use the generic name 'regulator@num' for those nodes. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: dts: imx6qdl: make pinctrl nodes board specificShawn Guo2014-02-091-11/+109
| | | | | | | | | | | | | | | | | | | Currently, all pinctrl setting nodes are defined in <soc>.dtsi, so that boards that share the same pinctrl setting do not have to define it time and time again in <board>.dts. However, along with the devices and use cases being added continuously, the pinctrl setting nodes under iomuxc becomes more than expected. This bloats device tree blob for particular board unnecessarily since only a small subset of those pinctrl setting nodes will be used by the board. It impacts not only the DTB file size but also the run-time device tree lookup efficiency. The patch moves all the pinctrl data into individual boards as needed. With the changes, the pinctrl setting nodes becomes local to particular board, and it makes no sense to continue numbering the setting for given peripheral. Thus, all the pinctrl phandler name gets updated to have only peripheral name in there. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
