iMX7D has two iomuxc controllers, iomuxc controller similar as previous iMX SoC generation and iomuxc-lpsr which provides low power state rentetion capabilities on gpios that are part of iomuxc-lpsr - Add iomuxc-lpsr gpio group id's - Use flag ZERO_OFFSET_VALID and SHARE_INPUT_SELECT_REG to properly set pads from iomuxc-lpsr domain Signed-off-by: Adrian Alonso <aalonso@freescale.com> --- Changes for V2: Add imx7d_lpsr_pads enums Changes for V3: Resend Changes for V4: Resend drivers/pinctrl/freescale/pinctrl-imx7d.c | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+)
