[PATCH v2 0/2] TQMa6UL[L]x[L] DT improvements

[Alexander Stein]

Hi everyone,

this small series improves the DT for TQMa6UL[L]x[L] a bit.
Ethernet PHY IRQ support can now be added. And the on-board USB hub
is explicitly specified.

Changes are mentioned in their respective patches.

Thanks and best regards,
Alexander

[PATCH v2 1/2] ARM: dts: mba6ulx: Add Ethernet PHY interrupt support

[Alexander Stein]

With commit 417b0f8d08f87 ("gpio: pca953x: Add support for level-triggered
interrupts") the GPIO expander gained support for level-low interrupts
required for Ethernet PHYs

[PATCH v2 2/2] ARM: dts: mba6ulx: Add USB hub node

[Alexander Stein]

Instead of handling the USB hub reset using a regulator, add a proper
on-board USB hub device with reset-gpios set.
