2017-07-08net: hns: Fix a wrong op phy C45 codeYunsheng Lin1-1/+1
As the user manual described, the second step to write to C45 phy by mdio should be data, but not address. Here we should fix this issue.

2016-10-17net: hisilicon: Fix hns_mdio module autoload for OF registrationJavier Martinez Canillas1-0/+1
If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro. Before this patch: $ modinfo drivers/net/ethernet/hisilicon//hns_mdio.ko | grep alias alias: platform:Hi-HNS_MDIO alias: acpi*:HISI0141:* After this patch: $ modinfo drivers/net/ethernet/hisilicon//hns_mdio.ko | grep alias alias: platform:Hi-HNS_MDIO alias: of:N*T*Chisilicon,hns-mdioC* alias: of:N*T*Chisilicon,hns-mdio alias: of:N*T*Chisilicon,mdioC* alias: of:N*T*Chisilicon,mdio alias: acpi*:HISI0141:* Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: David S.

Since the registers of subctrl may be different, it is better to mv the registers from hns mdio driver routine to device tree node. Signed-off-by: Kejian Yan <yankejian@huawei.com> Signed-off-by: Yisen Zhuang <Yisen.Zhuang@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-04net: hisilicon: add support of acpi for hns-mdioKejian Yan1-37/+69
hns-mdio needs to register itself to mii-bus. The info of the device can be read by both DT and ACPI. HNS tries to call Linux PHY driver to help access PHY-devices, the HNS hardware topology is as below. The MDIO controller may control several PHY-devices, and each PHY-device connects to a MAC device. The MDIO will be registered to mdiobus, then PHY-devices will register when each mac find PHY device. cpu | | ------------------------------------------- | | | | | | | dsaf | MDIO | MDIO | --------------------------- | | | | | | | | | | | | | | MAC MAC MAC MAC | | | | | | | ---- |-------- |-------- | | -------- || || || || PHY PHY PHY PHY And the driver can handle reset sequence by _RST method in DSDT in ACPI case.

Have mdio_alloc() create the array of interrupt numbers, and initialize it to POLLING. This is what most MDIO drivers want, so allowing code to be removed from the drivers.
