IMX27: How to do 22k pull-up with the pinctrl ?

[Chris Ruehl]

Hi,

while I port the static code to the DT I step into the problem to
set the PSCR for the sdhc2 ports to 22k pull-up
I look for something like described in
    pinctrl/fsl,imx-pinctrl.txt

the fsl,imx27-pinctrl only say 0/1 dis/enable pull up but not the strength.


pinctrl_sdhc2_1: sdhc2-1 {
                        fsl,pins = <
                                MX27_PAD_SD2_D0__SD2_D0  0x1
                                MX27_PAD_SD2_D1__SD2_D1  0x1
                                MX27_PAD_SD2_D2__SD2_D2  0x1
                                MX27_PAD_SD2_D3__SD2_D3  0x1
                                MX27_PAD_SD2_CLK__SD2_CLK  0x1
                                MX27_PAD_SD2_CMD__SD2_CMD  0x1
                        >;
                };

its setup in board specific c-file

/* 22k pull-up for sd2 pins  */
        reg = __raw_readw(MX27_IO_ADDRESS(MX27_SYSCTRL_BASE_ADDR + 
MX27_SYS_PSCR));
        reg &= ~0xfff0;
        reg |= 0xfff0;
        __raw_writew(reg, MX27_IO_ADDRESS(MX27_SYSCTRL_BASE_ADDR + 
MX27_SYS_PSCR));


Any successions?

Regards
Chris
