mb/google/zork: Drop unnecessary PULL_UPs for dalboz reference
This change drops internal pulls for dalboz reference configured on pads which already have external pull-ups in hardware. GPIO_0(PWR_BTN_L): Pulled up to PP3300_A GPIO_2(WAKE_L): Pulled up to PP3300_A GPIO_10: Unused. Changed to PAD_NC. GPIO_11(EC_IN_RW_OD): Pulled up to PP3300_A GPIO_12(USI_INT_ODL): Pulled up to PP3300_A GPIO_16(USB_OC0_L): Pulled up to PP3300_A GPIO_17(USB_OC1_L): Pulled up to PP3300_A GPIO_21(EMMC_CMD): Pulled up to PP1800_S0 GPIO_22(EC_FCH_SCI_ODL): Pulled up to PP3300_A GPIO_31(EC_AP_INT_ODL): Pulled up to PP1800_A GPIO_32: Unused. Changed to PAD_NC. GPIO_113(I2C2_SCL): Pulled up to PP3300_S0 GPIO_114(I2C2_SDA): Pulled up to PP3300_S0 GPIO_129(KBRST_L): Pulled up to PP1800_S0 GPIO_92(CLK_REQ0_L): Pulled up to PP3300_S0 GPIO_115(CLK_REQ1_L): Pulled up to PP3300_S0 GPIO_116(CLK_REQ2_L): Pulled up to PP3300_S0 BUG=b:154351731 Change-Id: I62e9dbac7a55efa1e055983a7c126168ee516151 Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/43555 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
