drivers: net: phy: xgene: Fix 'remove' function

2016-09-13T16:04:11Z

If 'IS_ERR(pdata->clk)' is true, then 'clk_disable_unprepare(pdata->clk)' will do nothing. It is likely that 'if (!IS_ERR(pdata->clk))' was expected here. In fact, the test can even be removed because 'clk_disable_unprepare' already handles such cases. Signed-off-by: Christophe JAILLET Signed-off-by: David S. Miller

drivers: net: phy: mdio-xgene: Add hardware dependency

2016-09-10T02:29:40Z

The mdio-xgene driver is only useful on X-Gene SoC. Signed-off-by: Jean Delvare Cc: Iyappan Subramanian Cc: David S. Miller Acked-by: Iyappan Subramanian Signed-off-by: David S. Miller

Revert "phy: IRQ cannot be shared"

2016-08-25T23:53:47Z

This reverts: commit 33c133cc7598 ("phy: IRQ cannot be shared") On hardware with multiple PHY devices hooked up to the same IRQ line, allow them to share it. Sergei Shtylyov says: "I'm not sure now what was the reason I concluded that the IRQ sharing was impossible... most probably I thought that the kernel IRQ handling code exited the loop over the IRQ actions once IRQ_HANDLED was returned -- which is obviously not so in reality..."

phy: micrel: Reenable interrupts during resume for ksz9031

2016-08-23T23:56:54Z

Like the ksz8081, the ksz9031 has the behavior where it will clear the interrupt enable bits when leaving power down. This takes advantage of the solution provided by f5aba91. Signed-off-by: Xander Huff Signed-off-by: Nathan Sullivan Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: micrel: Add specific suspend

2016-08-09T23:19:15Z

Disable all interrupts when suspend, they will be enabled when resume. Otherwise, the suspend/resume process will be blocked occasionally. Signed-off-by: Wenyou Yang Acked-by: Nicolas Ferre Signed-off-by: David S. Miller

phy/micrel: Change phy_id_mask for KSZ8721

2016-08-01T03:37:12Z

There are KSZ8721 PHYs with phy_id 0x00221619. In order to detect them as PHY_ID_KSZ8001 compatible while staying different to PHY_ID_KSZ9021 ignore the last two bits when matching PHY_ID Signed-off-by: Alexander Stein Signed-off-by: David S. Miller

drivers: net: phy: xgene: Remove redundant dev_err call in xgene_mdio_probe()

2016-07-31T03:39:12Z

There is a error message within devm_ioremap_resource already, so remove the dev_err call to avoid redundant error message. Signed-off-by: Wei Yongjun Acked-By: Iyappan Subramanian Signed-off-by: David S. Miller

drivers: net: phy: xgene: Add MDIO driver

2016-07-26T04:51:43Z

Currently, SGMII based 1G rely on the hardware registers for link state and sometimes it's not reliable. To get most accurate link state, this interface has to use the MDIO bus to poll the PHY. In X-Gene SoC, MDIO bus is shared across RGMII and SGMII based 1G interfaces, so adding this driver to manage MDIO bus. This driver registers the mdio bus and registers the PHYs connected to it.

Marvell phy: add functions to suspend and resume both interfaces: fiber and copper links.

These functions used standards registers in a different page for both interfaces: copper and fiber. Reviewed-by: Andrew Lunn Signed-off-by: Charles-Antoine Couret Signed-off-by: David S. Miller

Marvell phy: add configuration of autonegociation for fiber link.

2016-07-19T23:05:56Z

To be correctly initilized, the fiber interface needs to be configured via autonegociation registers which use some customs options or registers. Reviewed-by: Andrew Lunn Signed-off-by: Charles-Antoine Couret Signed-off-by: David S. Miller
