* Phy: Check NULL bus case and undetected phy via ofClément Leger2017-09-061-0/+5
| | | | | | | | | | | | | | | From 5e87dc2c24051c2cd2985e513c5a825d51d9bb00 Mon Sep 17 00:00:00 2001 From: Clement Leger <clement.leger@kalray.eu> Date: Tue, 5 Sep 2017 10:37:23 +0200 Subject: [PATCH] Phy: Check NULL bus case and undetected phy via of phy_device_connect can be called with NULL miibus for automatic match with the phy described in the device tree. In the case where the phy was not detected for some unknown reason, the next calls will be done with a NULL bus. This will lead to undefined behavior and more probably crashes.

* param: make parameter functions more consistentSascha Hauer2017-04-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: phy: micrel: Do not overwrite reserved bitsSascha Hauer2016-11-081-1/+5
| | | | | | | | | | | | | | ksz8021_config_init() unconditionally sets the KSZPHY_OMSO_RMII_OVERRIDE bit. This is since the initial micrel phy commit, so it's not reproducible where this comes from and why this is done. Neither U-Boot nor the kernel ever touch this bit and so should we. Also, instead of doing a write only operation, read/modify/write the bit we actually want to change. This fixes operation on a KSZ8081MLX which is a MII only phy. KSZPHY_OMSO_RMII_OVERRIDE is reserved here and must be written to 0. KSZPHY_OMSO_MII_OVERRIDE is default 1 and must be written as 1. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | Change the way PHY devices are named upon creation. This commit replaces sequentialy numbered "/dev/phy%d" with "/dev/mdio%d-phy%02x". This way it is significanlty easier to identify which PHY in real-life (e.g. on a schematic) corresponds to which device in /dev. Also, replace asprintf with xasprintf to provide some form of memory allocation failure checking.

|/ | | | | | | | | | | | | | | | | | | | | | | | This fixes: 80264a8 driver: Call bus->remove instead of driver->remove On mvebu it happens that: Upon device shutdown, when iterating through the active device list, the phy0 device is removed before mdio-mvebu. Then, when the mdio bus device is removed, the phy0 device is removed again, here: mdio_bus_remove(on mdio-mvebu) mvebu_mdio_remove mdiobus_unregister unregister_device mdio_bus_remove(on phy0) Fix this by setting the mdio busses phy_map[phy->addr] to NULL when unregistering the phy device, so that mdiobus_unregister no longer finds a valid phy_device when iterating over the busses device list.
