bindings: net: stmmac: add missing note about LPI interrupt
The hardware has a LPI interrupt. There is already code in the stmmac driver to parse and handle the interrupt. However, this information was missing from the DT binding. At the same time, improve the description of the existing interrupts. Signed-off-by: Niklas Cassel <niklas.cassel@axis.com> Acked-By: Joao Pinto <jpinto@synopsys.com> Signed-off-by: David S.

|
|||
- interrupt-parent: Should be the phandle for the interrupt controller
|
||||
that services interrupts for this device
|
||||
- interrupts: Should contain the STMMAC interrupts
|
||||
- interrupt-names: Should contain the interrupt names "macirq"
|

"eth_wake_irq" if this interrupt is supported in the "interrupts"
|
||||
property
|
||||
- interrupt-names: Should contain a list of interrupt names corresponding to
|
||||
the interrupts in the interrupts property, if available.
|
||||
Valid interrupt names are:
|
||||
- "macirq" (combined signal for various interrupt events)
|
||||
- "eth_wake_irq" (the interrupt to manage the remote wake-up packet detection)
|
||||
- "eth_lpi" (the interrupt that occurs when Tx or Rx enters/exits LPI state)
|
||||
- phy-mode: See ethernet.txt file in the same directory.
|
||||
- snps,reset-gpio gpio number for phy reset.
|
||||
- snps,reset-active-low boolean flag to indicate if phy reset is active low.
