2018-05-17	dts: pinctrl: Provide IMX_PAD_SION definition for imx53 pinctrl	Lukasz Majewski
	The SION pin must be set for proper operation of I2C when DM is enabled. When legacy I2C is used, this bit is set implicitly in the u-boot code: arch/arm/include/asm/arch-mx5/iomux-mx53.h:92: MX53_PAD_KEY_ROW3__I2C2_SDA = IOMUX_PAD(0x368, 0x040, 4 \| IOMUX_CONFIG_SION, 0x820, 0, NO_PAD_CTRL), The Linux kernel uses similar approach with: arch/arm/boot/dts/imx53-tqma53.dtsi:182: MX53_PAD_KEY_ROW3__I2C2_SDA 0xc0000000 After applying this patch it is possible to have the I2C working with DM on imx53 devices: MX53_PAD_KEY_ROW3__I2C2_SDA (0x1ee \| IMX_PAD_SION) Signed-off-by: Lukasz Majewski <lukma@denx.de>
2016-12-16	arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC	Patrick Bruenn
	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>
