i.mx 53 qsb start-r pin pad macros

Question asked by Poorna T on May 1, 2013

hi everyone......

I am new to embedded...., presently working on imx53 QSB start-r.

Can anyone clarify what following macros actually return or what actually they mean....?

Macros are available in \kernel\arch\arm\plat-mxc\include\mach\iomux-mx53.h

.

I am using linaro build of ICS.

 

#define MX53_PAD_KEY_ROW0__UART4_RXD_MUX      (_MX53_PAD_KEY_ROW0__UART4_RXD_MUX | MUX_PAD_CTRL(MX53_UART_PAD_CTRL))
and

#define MX53_PAD_CSI0_DAT13__UART4_RXD_MUX      (_MX53_PAD_CSI0_DAT13__UART4_RXD_MUX | MUX_PAD_CTRL(MX53_UART_PAD_CTRL))

 

What is the actual difference in using these macros, in which context should each be used??

here I am also attaching iomux-mx53.h file....

Thanks...
