   4 Subject: [PATCH] ARM: dts: BCM5301X: Fix I2C controller interrupt
   5
   6 The I2C interrupt controller line is off by 32 because the datasheet
   7 describes interrupt inputs into the GIC which are for Shared Peripheral
   8 Interrupts and are starting at offset 32. The ARM GIC binding expects
   9 the SPI interrupts to be numbered from 0 relative to the SPI base.
