-Subject: [PATCH mvebu-dt] ARM: dts: turris-omnia: configure LED[2]/INTn pin as interrupt pin
-Date: Sun, 21 Feb 2021 00:11:44 +0100
-Message-Id: <20210220231144.32325-1-kabel@kernel.org>

-
-Use the `marvell,reg-init` DT property to configure the LED[2]/INTn pin
-of the Marvell 88E1514 ethernet PHY on Turris Omnia into interrupt mode.
-
-Without this the pin is by default in LED[2] mode, and the Marvell PHY
-driver configures LED[2] into "On - Link, Blink - Activity" mode.
-
-This fixes the issue where the pca9538 GPIO/interrupt controller (which
-can't mask interrupts in HW) received too many interrupts and after a
-time started ignoring the interrupt with error message:
- IRQ 71: nobody cared
-
-There is a work in progress to have the Marvell PHY driver support
-parsing PHY LED nodes from OF and registering the LEDs as Linux LED
-class devices. Once this is done the PHY driver can also automatically
-set the pin into INTn mode if it does not find LED[2] in OF.
-
-Until then, though, we fix this via `marvell,reg-init` DT property.

----
-
-This patch fixes bug introduced with the commit that added Turris
-Omnia's DTS (26ca8b52d6e1), but will not apply cleanly because there is
-commit 8ee4a5f4f40d which changed node name and node compatible
-property and this commit did not go into stable.
-
-So either commit 8ee4a5f4f40d has also to go into stable before this, or
-this patch has to be fixed a little in order to apply to 4.14+.
-
-Please let me know how should I handle this.
