* dm: i2c: mxc_i2c: implement i2c_idle_busPeng Fan2016-03-28-0/+10

The i2c_idle_bus force bus idle flow follows setup_i2c in arch/arm/imx-common/i2c-mxv7.c This patch is an implementation following linux kernel patch: " commit 1c4b6c3bcf30d0804db0d0647d8ebeb862c6f7e5 Author: Gao Pan <b54642@freescale.com> Date: Fri Oct 23 20:28:54 2015 +0800 i2c: imx: implement bus recovery Implement bus recovery methods for i2c-imx so we can recover from situations where SCL/SDA are stuck low. Once i2c bus SCL/SDA are stuck low during transfer, config the i2c pinctrl to gpio mode by calling pinctrl sleep set function, and then use GPIO to emulate the i2c protocol to send nine dummy clock to recover i2c device. After recovery, set i2c pinctrl to default group setting. " See Documentation/devicetree/bindings/i2c/i2c-imx.txt for detailed description. 1. Introuduce scl_gpio/sda_gpio/bus in mxc_i2c_bus. 2. Discard the __weak attribute for i2c_idle_bus and implement it, since we have pinctrl driver/driver model gpio driver. We can use device tree, but not let board code to do this. 3. gpio state for mxc_i2c is not a must, but it is recommended. If there is no gpio state, driver will give tips, but not fail. 4. The i2c controller was first probed, default pinctrl state will be used, so when need to use gpio function, need to do "pinctrl_select_state(dev, "gpio")" and after force bus idle, need to switch back "pinctrl_select_state(dev, "default")". This is example about how to use the gpio force bus idle function: " &i2c1 { clock-frequency = <100000>; pinctrl-names = "default", "gpio"; pinctrl-0 = <&pinctrl_i2c1>; pinctrl-1 = <&pinctrl_i2c1_gpio>; scl-gpios = <&gpio1 28 GPIO_ACTIVE_HIGH>; sda-gpios = <&gpio1 29 GPIO_ACTIVE_HIGH>; status = "okay"; [....] }; [.....] pinctrl_i2c1_gpio: i2c1grp_gpio { fsl,pins = < MX6UL_PAD_UART4_TX_DATA__GPIO1_IO28 0x1b8b0 MX6UL_PAD_UART4_RX_DATA__GPIO1_IO29 0x1b8b0 >; }; " Signed-off-by: Peng Fan <van.freenix@gmail.com> Cc: Albert Aribaud <albert.u.boot@aribaud.net> Cc: Stefano Babic <sbabic@denx.de> Cc: Heiko Schocher <hs@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: York Sun <york.sun@nxp.com>

* video: mxsfb: introduce lcdif_power_downPeng Fan2015-11-12-0/+2
| | | | | | | | | | | | | | | | | | Introudce a new function lcdif_power_down. 1. Waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage. 2. Add power down function to stop lcdif. The reason to introduce lcdif_power_down is that we want lcdif to be in initial state when doing uboot reset or before kernel boot to make system stable, otherwise system may hang.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Introduce a new structure `struct mxc_i2c_bus`, this structure will used for non-DM and DM. 2. Remove `struct mxc_i2c_regs` structure, but use register offset to access registers based on `base` entry of `struct mxc_i2c_bus`. 3. Remove most `#ifdef I2C_QUIRK_REG`. Using driver_data to contain platform flags. A new flag is introduced, I2C_QUIRK_FLAG. 4. Most functions use `struct mxc_i2c_bus` as one of the parameters. Make most functions common to DM and non-DM, try to avoid duplicated code. 5. Support DM, but pinctrl is not included. Pinmux setting is still set by setup_i2c, but we do not need bus_i2c_init for DM. 6. struct i2c_parms and struct sram_data are removed. 7. Remove bus_i2c_read bus_i2c_write prototype in header file. The frist paramter of bus_i2c_init is modified to i2c index. Add new prototype i2c_idle_bus and force_bus_idle. Since bus_i2c_init is not good for DM I2C and pinctrl is missed, we use a weak function for i2c_idle_bus. Board file take the responsibility to implement this function, like this: " int i2c_idle_bus(struct mxc_i2c_bus *i2c_bus) { if (i2c_bus->index == 0) force_bus_idle(i2c_pads_info0); else if (i2c_bus->index == 1) force_bus_idle(i2c_pads_info1); else xxxxxx } " 8. Introduce a weak function, enable_i2c_clk 9. Tested on an i.MX7 platform.

| | | | | | | | | | | | | | | | | | Add special function that executes a specially crafted circular DMA descriptor. The function doesn't wait for the descriptor to finish the transfer, since the descritor never finishes. This is useful when operating a SmartLCD through the LCDIF interface, as the LCDIF does not give us any means to have continuous refresh of the SmartLCD. Instead, the RUN bit in the LCDIF CTRL register must be triggered manually. This can be worked around by starting an DMA transfer which continuously sets the RUN bit. This function allows starting exactly such transfer.

* arm: vf610: Add IOMUX support for Vybrid VF610Alison Wang2013-06-03-0/+18
| | | | | | | | | | | | | This patch adds the IOMUX support for Vybrid VF610 platform. There is a little difference for IOMUXC module between VF610 and i.MX platform, the muxmode and pad configuration share one 32bit register on VF610, but they are two independent registers on I.MX platform. A CONFIG_IOMUX_SHARE_CONFIG_REG was introduced to fit this difference.

* tools: arm: imx: Implement BOOT_OFFSET command for imximageMarek Vasut2013-04-28-0/+30
| | | | | | | | | | | | | | | | | | | | Implement BOOT_OFFSET command for imximage. This command is parallel to current BOOT_FROM command, but allows more flexibility in configuring arbitrary image header offset. Also add an imximage.cfg with default offset values into arm/arch/imx-common/ so the board-specific imximage.cfg can include this file to avoid magic constants. The syntax of BOOT_OFFSET command is "BOOT_OFFSET <u32 offset>".

* imx: iomux-v3: Include PKE and PUE to pad control pull definitionsBenoît Thébaudeau2013-04-28-5/+5
| | | | | | | | | | | | | | | | | PUE requires PKE to mean something, as do pull values with PUE, so do not compell users to explicitly use PKE and PUE everywhere. This is also what is done on Linux and what has already been done for i.MX51. By the way, remove some unused pad control definitions. There is no change of behavior. Note that SPI_PAD_CTRL was defined by several boards with a pull value, but without PKE or PUE, which means that no pull was actually enabled in the pad. This might be a bug in those boards, but this patch does not change the behavior, so it just removes the meaningless pull value from those definitions.
