I would like to know how do we configure the SPI2 MISO line with Pullup.
I have gone through the file hikey960-pinctrl.dtsi, but didnt understand how to configure MISO Pullup with below option.
spi2_cfg_func: spi2_cfg_func {
pinctrl-single,pins = <
0x09c 0x0 /* SPI2_CLK */
0x0a0 0x0 /* SPI2_DI */
0x0a4 0x0 /* SPI2_DO */
0x0a8 0x0 /* SPI2_CS0_N */
>;
pinctrl-single,bias-pulldown = <
PULL_DIS
PULL_DOWN
PULL_DIS
PULL_DOWN
>;
pinctrl-single,bias-pullup = <
PULL_UP
PULL_UP
PULL_DIS
PULL_UP
>;
pinctrl-single,drive-strength = <
DRIVE7_02MA DRIVE6_MASK
>;
};
