* dm: i2c: mxc_i2c: implement i2c_idle_busPeng Fan2016-03-28-9/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement i2c_idle_bus in driver, then setup_i2c can be dropped for boards which enable DM_I2C/DM_GPIO/PINCTRL. 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>

| * sunxi: Configure only LVDS pins instead of all LCD pins when LVDS interface ↵Lawrence Yu2016-03-23-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | selected The behavior before this patch would attempt to configure the mux setting for pins 0 to 27 on PORTD to all be setting 3 for LVDS. The LVDS interface actually only uses pins 18 to 27 and not pins 0 to 27 as in the parallel LCD interface. This patch restricts the configuration to only the relevant pins 18 to 27 on PORTD. This was tested on a sun8i A33 tablet with an LVDS screen. MMC1 has the capability to use pins 2 to 7 on PORTD and the mux on those pins was being inadvertently set to setting 3 for MMC functionality which this patch corrects.
