* ARM: dts: imx28-m28evk: Fix display duplicate name warningFabio Estevam2014-09-161-2/+2
| | | | | | | | | | | | The lcdif node has a property named "display" and also a child node called "display", which causes the following warning: device-tree: Duplicate name in lcdif@80030000, renamed to "display#1" Rename the child node name in order to avoid the warning.

* ARM: dts: mxs: Split M28EVK into SoM and EVK partsMarek Vasut2014-07-181-61/+1
| | | | | | | | | This patch splits the M28EVK device tree file into a common SoM part and an EVK part. This is needed to make it easier for users of the SoM to put it into different, non-reference baseboard. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Shawn Guo <shawn.guo@freescale.com>
* ARM: dts: mxs: Fix the RTC compatible prop on M28EVKMarek Vasut2014-02-211-1/+1
| | | | | | | The compatible property should be m41t62, not mt41t62, so fix this. Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: i.MX28: dts: rename usbphy pin namesMichael Grzeschik2014-02-091-2/+2
| | | | | | | | The pins have nothing todo with the phy layer. We better rename them, so it gets clear they are routed to the ehci core not to any phy. Signed-off-by: Michael Grzeschik <m.grzeschik@pengutronix.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: dts: imx: use generic node name for fixed regulatorShawn Guo2014-02-091-4/+10
| | | | | | | | 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: mxs: modify mx23/mx28 dts files to use padconfig definesLothar Waßmann2013-09-261-6/+6
| | | | | | | | Convert mx23/mx28 dts files to use the padconfig defintions from mxs-pinfunc.h. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: dts: mxs: modify mx23/mx28 dts files to use pinctrl headersLothar Waßmann2013-09-261-8/+8
| | | | | | | | | | | | | | | | | | Convert mx23/mx28 dts filed to use the pinctrl header files. NOTE: During automatic conversion of these files to use the pinconfig definitions an inconsistency has been found in: arch/arm/boot/dts/imx28-apx4devkit.dts According to the comment the function for pad SSP2_SS0 should have been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131 represents: MX28_PAD_SSP2_SS0__AUART3_TX I used the later (though probably wrong) definition because that's what is actually being used in the DTB.

* ARM: mxs: saif0 is the clock provider to sgtl5000Shawn Guo2013-07-151-1/+1
| | | | | | | | These systems all use saif0 as the mclock provider to codec sgtl5000. Reflect that in device tree source, so that sgtl5000 can find the clock by calling clk_get(). Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: mxs: Fix UARTs on M28EVKMarek Vasut2013-06-171-1/+13

* Merge branch 'late/dt' into next/dt2Arnd Bergmann2013-05-061-1/+0
|\ | | | | | | | | | | | | | | | | | | | | | | | | This is support for the ARM Chromebook, originally scheduled as a "late" pull request. Since it's already late now, we can combine this into the existing next/dt2 branch. * late/dt: ARM: exynos: dts: cros5250: add EC device ARM: dts: Add sbs-battery for exynos5250-snow ARM: dts: Add i2c-arbitrator bus for exynos5250-snow ARM: dts: Add chip-id controller node on Exynos4/5 SoC ARM: EXYNOS: Create virtual I/O mapping for Chip-ID controller using device tree
| * ARM: mxs: Slow down the I2C clock speedMarek Vasut2013-04-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Slow down the I2C clock speed on M28 and SPS1 as it turns out the I2C block in i.MX28 can not operate stable enough with the bus running at 400kHz. Note that the driver used by Freescale runs the bus at 250kHz when 400kHz speed is selected, but the mainline Linux kernel runs the bus at actual 400kHz and that's where it is occasionally unstable. Play safe and run the bus at 100kHz. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* | ARM: mxs: move display timing configurations into device treeShawn Guo2013-04-041-0/+25

* | ARM: dts: mxs: add enet_out clock to devicetreeWolfram Sang2013-04-041-0/+2
|/ | | | | | | | | | Put the clock to the devicetree, so the driver can take care of it later. Then, we don't have to do the enabling as a workaround in board init.

* ARM: mxs: Update DENX M28 machine and dts fileMarek Vasut2012-08-281-6/+73
| | | | | | | | | | | Update the mach-mxs machine by removing the enet_clkout(). The new revision of the board doesn't need that. Also, update the DTS file with all the new drivers pulled in the mainline recently, that is, SPI, LRADC, USB.

| | | | | | | | hog_pins is used to setup the pin functions, and it is not neccesarily used only for GPIO pins, so use only 'hog' to describe a more generic term. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
* ARM: mxs: rename dts files with soc name being the prefixShawn Guo2012-07-111-0/+210
Rename mxs dts files with soc name being the prefix, so that the board dts file can be located easily by soc name, and we also gain the consistency of naming. Suggested-by: Marek Vasut <marex@denx.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
