The first supported SoC is Hi3798MV200.

Signed-off-by: Yang Xiwen forbidden405@outlook.com --- This patchset adds support for HiSTB ioconfig module. The module is used to set pins config(e.g. pull-up, pull-down, drive-strength etc..) and pinmux.

The first supported chip is Hi3798MV200. Adding support for Hi3798CV200 should be also easy.

Below is an example of the dts node:

```dts ioconfig: pinctrl@8a21000 { compatible = "hisilicon,hi3798mv200-ioconfig"; reg = <0x8a21000 0x180>; #pinctrl-cells = <1>;

emmc_default: emmc-default-state { cdata-pins { // CDATA0-7 pins = "W20", "V20", "U20", "V19", "Y21", "W21", "V21", "U21"; bias-pullup; slew-rate = <1>;

drive-strength = <8>; function = "emmc_cdata"; };

cclk-pin { pins = "T18";

bias-pullup; slew-rate = <1>;

drive-strength = <8>; function = "emmc_cclk"; };

ccmd-pin { pins = "T20";

bias-pullup; slew-rate = <1>;

drive-strength = <6>; function = "emmc_ccmd"; };

reset-pin { pins = "R20";

bias-disable; slew-rate = <1>;

drive-strength = <1>; function = "emmc_rst"; };

datastrobe-pin { pins = "R21";

bias-pullup; slew-rate;

drive-strength = <1>; function = "emmc_datastrobe"; }; }; }; ``` --- drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/hisilicon/Kconfig | 21 ++ drivers/pinctrl/hisilicon/Makefile | 6 + drivers/pinctrl/hisilicon/pinctrl-hi3798mv2x.c | 319 +++++++++++++++++++++++++ drivers/pinctrl/hisilicon/pinctrl-histb.c | 276 +++++++++++++++++++++ drivers/pinctrl/hisilicon/pinctrl-histb.h | 132 ++++++++++ 7 files changed, 756 insertions(+)
