From 2ae6cd5062d951a262c696b7c4f6f1dcaa2862fd Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sun, 16 Oct 2016 19:56:50 +0200 Subject: [PATCH] net: phy: Use threaded IRQ, to allow IRQ from sleeping devices The interrupt lines from PHYs maybe connected to I2C bus expanders, or from switches on MDIO busses. Such interrupts are sourced from devices which sleep, so use threaded interrupts. Threaded interrupts require that the interrupt requester also uses the threaded API. Change the phylib to use the threaded API, which is backwards compatible with none-threaded IRQs. Signed-off-by: Andrew Lunn Signed-off-by: David S.
