Subject: [net-next PATCH v7 0/6]  ACPI support for dpaa2 MAC driver.
Date: Sat, 25 Jul 2020 19:53:58 +0530
Message-ID: <20200725142404.30634-1-calvin.johnson@oss.nxp.com> (raw)

 This patch series provides ACPI support for dpaa2 MAC driver.
 This also introduces ACPI mechanism to get PHYs registered on a
 MDIO bus and provide them to be connected to MAC.

 Previous discussions on this patchset is available at:
 https://lore.kernel.org/linux-acpi/20200715090400.4733-1-calvin.johnson@oss.nxp.com/T/#t

 Patch "net: dpaa2-mac: Add ACPI support for DPAA2 MAC driver" depends on
 https://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux.git/commit/?h=acpi/for-next&id=c279c4cf5bcd3c55b4fb9709d9036cd1bfe3beb8
 Remaining patches are independent of the above patch and can be applied without
 any issues.

 Device Tree can be tested on LX2160A-RDB with the below change which is also
available in the above referenced patches:

Changes in v7:
- remove unnecessary -ve check for u32 var
- assign flags to phy_dev

Changes in v6:
- change device_mdiobus_register() parameter position
- improve documentation
- change device_mdiobus_register() parameter position
- clean up phylink_fwnode_phy_connect()

Changes in v5:
- add description
- clean up if else
- rename phy_find_by_fwnode() to phy_find_by_mdio_handle()
- add docment for phy_find_by_mdio_handle()
- error out DT in phy_find_by_mdio_handle()
- clean up err return
- return -EINVAL for invalid fwnode

Changes in v4:
- release fwnode_mdio after use
- return ERR_PTR instead of NULL
- introduce device_mdiobus_register()

Changes in v3:
- cleanup based on v2 comments
- Added description for more properties
- Added MDIO node DSDT entry
- introduce fwnode_mdio_find_bus()
- renamed and improved phy_find_by_fwnode()
- cleanup based on v2 comments
- move code into phylink_fwnode_phy_connect()

Changes in v2:
- clean up dpaa2_mac_get_node()
- introduce find_phy_device()
- use acpi_find_child_device()
