* ARM: dts: imx6sl-evk: Add an entry for MX6SL_PAD_ECSPI1_SS0__GPIO4_IO11Fabio Estevam2014-04-141-0/+1
| | | | | | | | | | | | | | | In case the bootloader has incorrectly configured the ALT mode of MX6SL_PAD_ECSPI1_SS0 pad, we end up with the following probe error: m25p80 spi0.0: found mr25h256, expected m25p32 m25p80 spi0.0: mr25h256 (32 Kbytes) In order to avoid this issue, add an entry for MX6SL_PAD_ECSPI1_SS0 pad, so that kernel configures the ECSPI chip select as GPIO functionality, which results in correct SPI NOR probe.

* ARM: dts: imx6sl-evk: Keep VGEN1 regulator always enabledFabio Estevam2014-02-201-0/+1
| | | | | | | | | | | | | | | | | | On imx6sl-evk board the VGEN1 regulator powers up the NVCC_1P2V domain of the imx6sl SoC, so we need to keep it always powered. According to imx6sl datasheet the GPIO block has three supplies: NVCC33_IO, NVCC18_IO and NVCC_1P2V and it states that: "All digital I/O supplies (NVCC_xxxx) must be powered under normal conditions whether the associated I/O pins are in use or not" This problem has been observed by the fact that a GPIO connected to an LED could not work when the PMIC driver was enabled. Keeping VGEN1 regulator always enabled fixes the problem. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

* 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: imx6sl: make pinctrl nodes board specificShawn Guo2014-02-091-14/+160
| | | | | | | | | | | | | | | | | | | 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>
