Merge branch 'stmmac-dwc-qos-ACPI-device-support'
Ajay Gupta says: ==================== net: stmmac: dwc-qos: ACPI device support Version 3 of patches have fixes for comments from Jakub Kicinski. These two changes are needed to enable ACPI based devices to use stmmac driver. First patch is to use generic device api (device_*) instead of device tree based api (of_*). Second patch avoids clock and reset accesses for Tegra ACPI based devices. ACPI interface will be used to access clock and reset for Tegra ACPI devices in later patches. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
