* dm: Fix up inclusion of common.hSimon Glass2017-06-014-0/+4
| | | | | | | | | | | | | | It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file.

* dm: Use dm.h header when driver mode is usedSimon Glass2017-06-015-5/+5
| | | | | | | | This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass <sjg@chromium.org>
* pinctrl: imx: fix memory leakPeng Fan2017-05-181-0/+4
| | | | | | | | | | | | | | | | Each time set_state is called, a new piece memory will be allocated for pin_data, but not freed, this will incur memory leak. When error, the devm API could not free memory automatically. So need call devm_kfree when error.

* dm: core: Replace of_offset with accessorSimon Glass2017-02-081-3/+4
| | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

* arm: imx: add i.MX53 Beckhoff CX9020 Embedded PCPatrick Bruenn2016-12-163-0/+59
| | | | | | | | | | | | | | | | Add CX9020 board based on mx53loco. Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse serial_mxc with DTE and prepare for device tree migration of other functions and imx53 devices. The CX9020 differs from i.MX53 Quick Start Board by: - use uart2 instead of uart1 - DVI-D connector instead of VGA - no audio - CCAT FPGA connected to emi - enable rtc Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com>

| | | | | | | | | | | Introudce i.MX7 pinctrl driver support. For now only i.MX7D supported. There are two iomux controllers in i.MX7D, iomuxc and iomuxc_lpsr. To iomuxc_lpsr, ZERO_OFFSET_VALID is set, means offset of mux_reg and conf_reg can begin at 0. Signed-off-by: Peng Fan <van.freenix@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* pinctrl: imx: Introduce pinctrl driver for i.MX6Peng Fan2016-02-215-0/+350
Introduce pinctrl for i.MX6 1. pinctrl-imx.c is for common usage. It's used by i.MX6/7. 2. Add PINCTRL_IMX PINCTRL_IMX6 Kconfig entry. 3. To the pinctrl_ops implementation, only set_state is implemented. To i.MX6/7, the pinctrl dts entry is as following: &iomuxc { pinctrl-names = "default"; pinctrl_csi1: csi1grp { fsl,pins = < MX6UL_PAD_CSI_MCLK__CSI_MCLK 0x1b088 MX6UL_PAD_CSI_PIXCLK__CSI_PIXCLK 0x1b088 MX6UL_PAD_CSI_VSYNC__CSI_VSYNC 0x1b088 >; }; [.....] }; there is no property named function or groups. So pinctrl_generic_set_state can not be used here. 5. This driver is a simple implementation for i.mx iomux controller, only parse the fsl,pins property and write value to registers. 6. With DEBUG enabled, we can see log when "i2c bus 0": " set_state_simple op missing imx_pinctrl_set_state: i2c1grp mux_reg 0x14c, conf_reg 0x3bc, input_reg 0x5d8, mux_mode 0x0, input_val 0x1, config_val 0x4000007f write mux: offset 0x14c val 0x10 select_input: offset 0x5d8 val 0x1 write config: offset 0x3bc val 0x7f mux_reg 0x148, conf_reg 0x3b8, input_reg 0x5d4, mux_mode 0x0, input_val 0x1, config_val 0x4000007f write mux: offset 0x148 val 0x10 select_input: offset 0x5d4 val 0x1 write config: offset 0x3b8 val 0x7f " this means imx6 pinctrl driver works as expected.
