Back then I couldn't -get it working though and I left it with i2c-gpio (which worked). - -Now we know the reason: the interrupt was incorrectly specified. -(Hence, this patch depends on Florian Fainelli's -"ARM: dts: BCM5301X: Fix I2C controller interrupt" patch). - -Cc: Florian Fainelli <f.fainelli@gmail.com> -Cc: Rafał Miłecki <zajec5@gmail.com> -Cc: Matthew Hagan <mnhagan88@gmail.com> -Signed-off-by: Christian Lamparter <chunkeey@gmail.com> -Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> ---- - arch/arm/boot/dts/bcm53016-meraki-mr32.dts | 62 ++++++++++------------ - 1 file changed, 28 insertions(+), 34 deletions(-) - ---- a/arch/arm/boot/dts/bcm53016-meraki-mr32.dts -+++ b/arch/arm/boot/dts/bcm53016-meraki-mr32.dts -@@ -84,40 +84,6 @@ - max-brightness = <255>; - }; - }; -- -- i2c { -- /* -- * The platform provided I2C does not budge. -- * This is a replacement until I can figure -- * out what are the missing bits... -- */ -- -- compatible = "i2c-gpio"; -- sda-gpios = <&chipcommon 5 GPIO_ACTIVE_HIGH>; -- scl-gpios = <&chipcommon 4 GPIO_ACTIVE_HIGH>; -- i2c-gpio,delay-us = <10>; /* close to 100 kHz */ -- #address-cells = <1>; -- #size-cells = <0>; -- -- current_sense: ina219@45 { -- compatible = "ti,ina219"; -- reg = <0x45>; -- shunt-resistor = <60000>; /* = 60 mOhms */ -- }; -- -- eeprom: eeprom@50 { -- compatible = "atmel,24c64"; -- reg = <0x50>; -- pagesize = <32>; -- read-only; -- #address-cells = <1>; -- #size-cells = <1>; -- -- mac_address: mac-address@66 { -- reg = <0x66 0x6>; -- }; -- }; -- }; - }; - - &uart0 { -@@ -250,3 +216,31 @@ - }; - }; - }; -+ -+&i2c0 { -+ status = "okay"; -+ -+ pinctrl-names = "default"; -+ pinctrl-0 = <&pinmux_i2c>; -+ -+ clock-frequency = <100000>; -+ -+ current_sense: ina219@45 { -+ compatible = "ti,ina219"; -+ reg = <0x45>; -+ shunt-resistor = <60000>; /* = 60 mOhms */ -+ }; -+ -+ eeprom: eeprom@50 { -+ compatible = "atmel,24c64"; -+ reg = <0x50>; -+ pagesize = <32>; -+ read-only; -+ #address-cells = <1>; -+ #size-cells = <1>; -+ -+ mac_address: mac-address@66 { -+ reg = <0x66 0x6>; -+ }; -+ }; -+}; |
