Add the bootph-all tag to all nodes that are used in the bootloader for the AM654 reference board. UARTs used as a console, the SD and eMMC nodes along with the needed regulators for UHS modes, and the needed nodes for OSPI boot are all marked with 'bootph-all' to handle the various boot modes the board is capable of Signed-off-by: Bryan Brattlof --- arch/arm64/boot/dts/ti/k3-am654-base-board.dts | 17 +++++++++++++++++ arch/arm64/boot/dts/ti/k3-am654-pcie-usb2.dtso | 1 + arch/arm64/boot/dts/ti/k3-am654-pcie-usb3.dtso | 1 + 3 files changed, 19 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-am654-base-board.dts b/arch/arm64/bo= ot/dts/ti/k3-am654-base-board.dts index c30425960398ebb75ebda44726ed90cd78947d58..e589690c7c8213d5e4989942735= fa53825e610f5 100644 --- a/arch/arm64/boot/dts/ti/k3-am654-base-board.dts +++ b/arch/arm64/boot/dts/ti/k3-am654-base-board.dts @@ -144,6 +144,7 @@ vtt_supply: regulator-3 { regulator-boot-on; vin-supply =3D <&vcc3v3_io>; gpio =3D <&wkup_gpio0 28 GPIO_ACTIVE_HIGH>; + bootph-all; }; }; =20 @@ -155,12 +156,14 @@ AM65X_WKUP_IOPAD(0x00a4, PIN_OUTPUT, 0) /* (AB5) WKUP= _UART0_TXD */ AM65X_WKUP_IOPAD(0x00c8, PIN_INPUT, 1) /* (AC2) WKUP_GPIO0_6.WKUP_UART0= _CTSn */ AM65X_WKUP_IOPAD(0x00cc, PIN_OUTPUT, 1) /* (AC1) WKUP_GPIO0_7.WKUP_UART= 0_RTSn */ >; + bootph-all; }; =20 ddr_vtt_pins_default: ddr-vtt-default-pins { pinctrl-single,pins =3D < AM65X_WKUP_IOPAD(0x0040, PIN_OUTPUT_PULLUP, 7) /* WKUP_GPIO0_28 */ >; + bootph-all; }; =20 wkup_i2c0_pins_default: wkup-i2c0-default-pins { @@ -168,6 +171,7 @@ wkup_i2c0_pins_default: wkup-i2c0-default-pins { AM65X_WKUP_IOPAD(0x00e0, PIN_INPUT, 0) /* (AC7) WKUP_I2C0_SCL */ AM65X_WKUP_IOPAD(0x00e4, PIN_INPUT, 0) /* (AD6) WKUP_I2C0_SDA */ >; + bootph-all; }; =20 push_button_pins_default: push-button-default-pins { @@ -191,6 +195,7 @@ AM65X_WKUP_IOPAD(0x0024, PIN_INPUT, 0) /* (R2) MCU_OSP= I0_D6 */ AM65X_WKUP_IOPAD(0x0028, PIN_INPUT, 0) /* (R3) MCU_OSPI0_D7 */ AM65X_WKUP_IOPAD(0x002c, PIN_OUTPUT, 0) /* (R4) MCU_OSPI0_CSn0 */ >; + bootph-all; }; =20 wkup_pca554_default: wkup-pca554-default-pins { @@ -206,6 +211,7 @@ AM65X_WKUP_IOPAD(0x0048, PIN_OUTPUT, 4) /* (P5) MCU_OSP= I1_D2.MCU_UART0_TXD */ AM65X_WKUP_IOPAD(0x004C, PIN_INPUT, 4) /* (P1) MCU_OSPI1_D3.MCU_UART0_C= TSn */ AM65X_WKUP_IOPAD(0x0054, PIN_OUTPUT, 4) /* (N3) MCU_OSPI1_CSn1.MCU_UART= 0_RTSn */ >; + bootph-all; }; =20 mcu_cpsw_pins_default: mcu-cpsw-default-pins { @@ -248,6 +254,7 @@ AM65X_IOPAD(0x01e8, PIN_OUTPUT, 0) /* (AE11) UART0_TXD = */ AM65X_IOPAD(0x01ec, PIN_INPUT, 0) /* (AG11) UART0_CTSn */ AM65X_IOPAD(0x01f0, PIN_OUTPUT, 0) /* (AD11) UART0_RTSn */ >; + bootph-all; }; =20 main_i2c2_pins_default: main-i2c2-default-pins { @@ -281,6 +288,7 @@ AM65X_IOPAD(0x0188, PIN_INPUT_PULLUP, 0) /* (D25) MMC0_= DAT7 */ AM65X_IOPAD(0x01b4, PIN_INPUT_PULLUP, 0) /* (A23) MMC0_SDCD */ AM65X_IOPAD(0x01b0, PIN_INPUT, 0) /* (C25) MMC0_DS */ >; + bootph-all; }; =20 main_mmc1_pins_default: main-mmc1-default-pins { @@ -294,6 +302,7 @@ AM65X_IOPAD(0x02c4, PIN_INPUT_PULLUP, 0) /* (D27) MMC1_= DAT3 */ AM65X_IOPAD(0x02dc, PIN_INPUT_PULLUP, 0) /* (B24) MMC1_SDCD */ AM65X_IOPAD(0x02e0, PIN_INPUT, 0) /* (C24) MMC1_SDWP */ >; + bootph-all; }; =20 usb1_pins_default: usb1-default-pins { @@ -343,6 +352,7 @@ &main_uart0 { pinctrl-names =3D "default"; pinctrl-0 =3D <&main_uart0_pins_default>; power-domains =3D <&k3_pds 146 TI_SCI_PD_SHARED>; + bootph-all; }; =20 &wkup_i2c0 { @@ -368,6 +378,7 @@ vdd_mpu: regulator@60 { ti,vsel0-state-high; ti,vsel1-state-high; ti,enable-vout-discharge; + bootph-all; }; =20 gpio@38 { @@ -456,6 +467,7 @@ &sdhci0 { bus-width =3D <8>; non-removable; ti,driver-strength-ohm =3D <50>; + bootph-all; }; =20 /* @@ -470,6 +482,7 @@ &sdhci1 { pinctrl-0 =3D <&main_mmc1_pins_default>; ti,driver-strength-ohm =3D <50>; disable-wp; + bootph-all; }; =20 &usb1 { @@ -630,3 +643,7 @@ &cpsw_port1 { &dss { status =3D "disabled"; }; + +&wkup_gpio0 { + bootph-all; +}; diff --git a/arch/arm64/boot/dts/ti/k3-am654-pcie-usb2.dtso b/arch/arm64/bo= ot/dts/ti/k3-am654-pcie-usb2.dtso index c3cb752f8cd79459d6d321dfdf0644748514a48d..d04dd7a44008205301ea3fb3d0a= 883b6a6a2562b 100644 --- a/arch/arm64/boot/dts/ti/k3-am654-pcie-usb2.dtso +++ b/arch/arm64/boot/dts/ti/k3-am654-pcie-usb2.dtso @@ -46,6 +46,7 @@ AM65X_IOPAD(0x02bc, PIN_OUTPUT, 0) /* (AD9) USB0_DRVVBUS = */ =20 &dwc3_0 { status =3D "okay"; + bootph-all; }; =20 &usb0_phy { diff --git a/arch/arm64/boot/dts/ti/k3-am654-pcie-usb3.dtso b/arch/arm64/bo= ot/dts/ti/k3-am654-pcie-usb3.dtso index 333e423e8bb6b033f5f45c782ef0095d29983158..04393f21d712ebd95ce1a411e2a= c13a56e63e57b 100644 --- a/arch/arm64/boot/dts/ti/k3-am654-pcie-usb3.dtso +++ b/arch/arm64/boot/dts/ti/k3-am654-pcie-usb3.dtso @@ -45,6 +45,7 @@ &dwc3_0 { <&k3_clks 151 8>; /* set PIPE3_TXB_CLK to WIZ8B2M4VSB */ phys =3D <&serdes0 PHY_TYPE_USB3 0>; phy-names =3D "usb3-phy"; + bootph-all; }; =20 &usb0 { --=20 2.49.0
