net: of_get_phy_mode: Change API to solve int/unit warnings

2019-11-04T19:21:25Z

Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.

net: dsa: remove dsa_switch_alloc helper

2019-10-22T19:37:07Z

Now that ports are dynamically listed in the fabric, there is no need to provide a special helper to allocate the dsa_switch structure. This will give more flexibility to drivers to embed this structure as they wish in their private structure. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: Jakub Kicinski

net: dsa: microchip: Add shared regmap mutex

2019-10-17T19:38:46Z

The KSZ driver uses one regmap per register width (8/16/32), each with it's own lock, but accessing the same set of registers. In theory, it is possible to create a race condition between these regmaps, although the underlying bus (SPI or I2C) locking should assure nothing bad will really happen and the accesses would be correct. To make the driver do the right thing, add one single shared mutex for all the regmaps used by the driver instead. This assures that even if some future hardware is on a bus which does not serialize the accesses the same way SPI or I2C does, nothing bad will happen. Note that the status_mutex was unused and only initied, hence it was renamed and repurposed as the regmap mutex. Signed-off-by: Marek Vasut Cc: Andrew Lunn Cc: David S.

The KSZ87xx driver calls mutex_init() on mutexes already inited in ksz_common.c ksz_switch_register(). Do not do it twice, drop the reinitialization.

net: dsa: microchip: Always set regmap stride to 1

2019-09-27T18:21:07Z

The regmap stride is set to 1 for regmap describing 8bit registers already. However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This is not correct, as the switch protocol supports unaligned register reads and writes and the KSZ87xx even uses such unaligned register accesses to read e.g. MIB counter. This patch fixes MIB counter access on KSZ87xx. Signed-off-by: Marek Vasut Cc: Andrew Lunn Cc: David S.
