Subject: [PATCH] ARM: dts: BCM5301X: Fix I2C controller interrupt
|
|
|
|
The I2C interrupt controller line is off by 32 because the datasheet
|
|
describes interrupt inputs into the GIC which are for Shared Peripheral
|
|
Interrupts and are starting at offset 32. The ARM GIC binding expects
|
|
the SPI interrupts to be numbered from 0 relative to the SPI base.
|
|
|
|
Fixes: bb097e3e0045 ("ARM: dts: BCM5301X: Add I2C support to the DT")
