X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=458d0c1d3a8dd05ae1bcd8daa3af7d50bd6f8587;p=thirdparty%2Fkernel%2Fstable.git

ARM: dts: stm32: update i2c nodes interrupt/dma in stm32mp151

Update all i2c nodes with the following properties:
  - replace interrupts with interrupts-extended and rely on exti
  - add dma properties
