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?
