2017-08-05	ARM: dts: imx53: add alternative UART2 configuration	Patrick Bruenn	1	-0/+4
	UART2 on EIM_D26 - EIM_D29 pins supports interchanging RXD/TXD pins and RTS/CTS pins. One board using these alternate settings is Beckhoff CX9020. Add the alternative configuration here, to make it available to others, too. Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2013-04-09	ARM: dts: imx53: fix SD2_DATA1 pad AUDMUX_AUD4 configuration	Marek Vasut	1	-1/+1
	The IOMUXC_AUDMUX_P4_INPUT_TXCLK_AMX_SELECT_INPUT must be configured as 1 instead of 0 to have AUD4 muxed on SD2 pins working.

2013-04-09	pinctrl: imx: move hard-coding data into device tree	Shawn Guo	1	-0/+1189
	Currently, all imx pinctrl drivers maintain a big array of struct imx_pin_reg which hard-codes data like register offset and mux mode setting for each pin function. Every time a new imx SoC support is added, we need to add such a big mount of data. With moving to single kernel build, it's only matter of time to be blamed on memory consuming. With DTC pre-processor support in place, the patch moves all these data into device tree by redefining the PIN_FUNC_ID in imxXX-pinfunc.h and changing the PIN_FUNC_ID parsing code a little bit. The pin id gets re-numbered based on mux register offset, or config register offset if the pin has no mux register, so that kernel can identify the pin id from register offsets provided by device tree. As a bonus point of the change, those arbitrary magic numbers standing for particular PIN_FUNC_ID in device tree sources are now replaced by macros to improve the readability of dts files.
