Add 3 helpers so that pincontrol definitions for pxa25x and pxa27x are
easier, and can be easily converted from old mfp mach-pxa code to
devicetree.
An example of such conversion would be :
static unsigned long mioa701_pin_config[] = {
GPIO32_MMC_CLK,
GPIO92_MMC_DAT_0,
GPIO109_MMC_DAT_1,
GPIO110_MMC_DAT_2,
GPIO111_MMC_DAT_3,
GPIO112_MMC_CMD,
MIO_CFG_IN(GPIO78_SDIO_RO, AF0),
MIO_CFG_IN(GPIO15_SDIO_INSERT, AF0),
MIO_CFG_OUT(GPIO91_SDIO_EN, AF0, DRIVE_LOW),
};
into:
pinctrl_mmc_default: mmc-default {
PMMUX(sd-insert, 15, gpio_in);
PMMUX(mmclk, 32, MMCLK);
PMMUX(sd-ro, 78, gpio_in);
PMMUX_LPM_LOW(sd-enable, 91, gpio_out);
PMMUX(mmdat0, 92, MMDAT<0>);
PMMUX(mmdat1, 109, MMDAT<1>);
PMMUX(mmdat2, 110, MMDAT<2>);
PMMUX(mmdat3, 111, MMDAT<3>);
PMMUX(mmcmd, 112, MMCMD);
};
The third column of PMMUX*() helpers can be found in pincontrol muxing
functions, either in pinctrl-pxa27x.c (or pinctrl-pxa25x.c), or by
inspecting the pincontrol once booted in debugfs.
