For I2C the danger is minimal (unless you have a ton of bus capacitance, then it changes high/low time), but it's best to write a more "pristine" DTS. (and sure, I know pretty much every board makes this mistake, but it's best if we don't proliferate the error) > +&i2c0 { > + pinctrl-names = "default"; > + pinctrl-0 = <&i2c0_pins>; > + > + status = "okay"; > + clock-frequency = <400000>; > + > + serial_config1: serial_config1@20 { > + compatible = "nxp,pca9539"; > + reg = <0x20>; > + }; > + > + serial_config2: serial_config2@21 { > + compatible = "nxp,pca9539"; > + reg = <0x21>; > + }; > + > + tps: tps@2d { > + reg = <0x2d>; which TPS device ? no compatible ? > +/include/ "tps65910.dtsi" oh... okay. > +&tps { > + vcc1-supply = <&vbat>; > + vcc2-supply = <&vbat>; > + vcc3-supply = <&vbat>; > + vcc4-supply = <&vbat>; > + vcc5-supply = <&vbat>; > + vcc6-supply = <&vbat>; > + vcc7-supply = <&vbat>; > + vccio-supply = <&vbat>; > + > + regulators { > + vrtc_reg: regulator@0 { > + regulator-always-on; this should not be always on, you want to pass this as supply to the RTC module so it can manage it.

Alright :-) Thanks.

Oh, so this 3.3V fixed rail is the same one derived from from the three possible power supplies you described above ? > >> +&am33xx_pinmux { > >> + mmc1_pins: pinmux_mmc1_pins { > >> + pinctrl-single,pins = < > >> + 0xf0 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat3 */ > >> + 0xf4 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat2 */ > >> + 0xf8 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat1 */ > >> + 0xfc (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_dat0 */ > >> + 0x100 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_clk */ > >> + 0x104 (PIN_INPUT_PULLUP | MUX_MODE0) /* mmc0_cmd */ > >> + >; > >> + }; > >> + > >> + i2c0_pins: pinmux_i2c0_pins { > >> + pinctrl-single,pins = < > >> + 0x188 (PIN_INPUT_PULLUP | MUX_MODE0) /* i2c0_sda.i2c0_sda */ > >> + 0x18c (PIN_INPUT_PULLUP | MUX_MODE0) /* i2c0_scl.i2c0_scl */ > >> + >; > >> + }; > >> + > >> + i2c2_pins: pinmux_i2c2_pins { > >> + pinctrl-single,pins = < > >> + 0x178 (PIN_INPUT_PULLUP | MUX_MODE3) /* uart1_ctsn.i2c2_sda */ > >> + 0x17c (PIN_INPUT_PULLUP | MUX_MODE3) /* uart1_rtsn.i2c2_scl */ > > > > on thing to keep in mind, if you already have external pullups, you > > might not want to add internal pullups as you'd end up with both > > resistors in parallel.

But it's still nice to add a compatible to that tps node, then again, it's added to tps65910.dtsi so that would be a very minor nit. > >> +&tps { > >> + vcc1-supply = <&vbat>; > >> + vcc2-supply = <&vbat>; > >> + vcc3-supply = <&vbat>; > >> + vcc4-supply = <&vbat>; > >> + vcc5-supply = <&vbat>; > >> + vcc6-supply = <&vbat>; > >> + vcc7-supply = <&vbat>; > >> + vccio-supply = <&vbat>; > >> + > >> + regulators { > >> + vrtc_reg: regulator@0 { > >> + regulator-always-on; > > > > this should not be always on, you want to pass this as supply to the RTC > > module so it can manage it.

My comment is regarding "ti,vcc-aux-disable-is-sleep", it's not documentated or used anywhere :-) cheers -- balbi [-- Attachment #2: Digital signature --] [-- Type: application/pgp-signature, Size: 819 bytes --] ^ permalink raw reply [flat|nested] 5+ messages in thread
