From 69eafa62d60b993ba9500f56af568357b16b1504 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Fri, 10 Nov 2017 14:33:28 +0100 Subject: [PATCH 44/82] ARM: dts: sun8i-a83t-tbs-a711: Add PN544 NFC support Regulators on the schematic are named incorrectly. Both cameras are is in fact connected to the dvdd-csi-f regulator and dvdd-csi-r is in reality used for digital pad supply for NFC chip. At the same time vcc-mipi regulator is not used for MIPI, but for NFC VBAT power. Interpreting schematics is an art form! :D Signed-off-by: Ondrej Jirman --- arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts | 18 +++++++++++++++--- 1 file changed, 15 insertions(+), 3 deletions(-) diff --git a/arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts b/arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts index ec986498114e..787277f4d455 100644 --- a/arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts +++ b/arch/arm/boot/dts/sun8i-a83t-tbs-a711.dts @@ -277,6 +277,16 @@ interrupt-parent = <&pio>; interrupts = <6 12 IRQ_TYPE_EDGE_FALLING>; /* PG12 */ }; + + /* NFC (NPC 100) */ + npc100: nfc@28 { + compatible = "nxp,nxp-nci-i2c"; + reg = <0x28>; + interrupt-parent = <&r_pio>; + interrupts = <0 6 IRQ_TYPE_LEVEL_HIGH>; /* PL6 */ + enable-gpios = <&pio 3 2 GPIO_ACTIVE_HIGH>; /* PD2 */ + firmware-gpios = <&pio 3 3 GPIO_ACTIVE_HIGH>; /* PD3 */ + }; }; &mmc0 { @@ -434,9 +444,10 @@ }; ®_dldo2 { - regulator-min-microvolt = <2800000>; + regulator-min-microvolt = <3300000>; regulator-max-microvolt = <4200000>; - regulator-name = "vcc-mipi"; + regulator-name = "vbat-nfc"; + regulator-always-on; }; ®_dldo3 { @@ -459,7 +470,8 @@ ®_eldo1 { regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; - regulator-name = "dvdd-csi-r"; + regulator-name = "pvdd-nfc"; + regulator-always-on; }; ®_eldo2 { -- 2.20.1
