* powerpc/fsl: fsl_soc: delete unneeded test before of_node_putJulia Lawall2014-11-101-2/+1
| | | | | | | | | | | | | | | | | | | | | | | Of_node_put supports NULL as its argument, so the initial test is not necessary. Suggested by Uwe Kleine-König.

* powerpc: Convert power off logic to pm_power_offAlexander Graf2014-11-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic Linux framework to power off the machine is a function pointer called pm_power_off. The trick about this pointer is that device drivers can potentially implement it rather than board files. Today on powerpc we set pm_power_off to invoke our generic full machine power off logic which then calls ppc_md.power_off to invoke machine specific power off. However, when we want to add a power off GPIO via the "gpio-poweroff" driver, this card house falls apart. That driver only registers itself if pm_power_off is NULL to ensure it doesn't override board specific logic. However, since we always set pm_power_off to the generic power off logic (which will just not power off the machine if no ppc_md.power_off call is implemented), we can't implement power off via the generic GPIO power off driver. To fix this up, let's get rid of the ppc_md.power_off logic and just always use pm_power_off as was intended. Then individual drivers such as the GPIO power off driver can implement power off logic via that function pointer. With this patch set applied and a few patches on top of QEMU that implement a power off GPIO on the virt e500 machine, I can successfully turn off my virtual machine after halt.

* powerpc/fsl: fsl_soc: remove 'fixed-link' parsing codeFlorian Fainelli2014-05-221-32/+0
| | | | | | | | | | | | | | | | | | | | | Parsing and registration of fixed PHY devices was needed with the use of of_phy_connect_fixed_link() because this function was using the designated PHY address identifier (first cell of the property) as the address to bind the PHY on the emulated bus. Since commit 3be2a49e5c08d268f8af0dd4fe89a24ea8cdc339 ("of: provide a binding for fixed link PHYs") a new pair of functions has been introduced which allows for dynamic address allocation of these fixed PHY devices, but also parses the old 'fixed-link' 5-digit property. Registration of fixed PHY early in platform code was needed because we could not issue a fixed MDIO bus re-scan within network drivers. The fixed PHYs had to be registered before the network drivers would call of_phy_connect_fixed_link(). All of these caveats are solved now, such that we can safely remove of_add_fixed_phys() now.

The driver uses usual of-style binding, available EHCI-HCD and UDC drivers can be bound to the created devices.

* gianfar: Fix race in TBI/SerDes configurationTrent Piepho2008-10-311-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The init_phy() function attaches to the PHY, then configures the SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

* | phy: Change mii_bus id field to a stringAndy Fleming2008-04-161-2/+3
|/ | | | | | | | | | Having the id field be an int was making more complex bus topologies excessively difficult. For now, just convert it to a string, and change all instances of "bus->id = val" to snprintf(id, MII_BUS_ID_LEN, "%x", val).

* [POWERPC] fsl_spi: stop using device_type = "spi"Anton Vorontsov2008-01-281-38/+60
| | | | | | | | | | | Also: - rename "fsl_spi" to "fsl,spi"; - add and use cell-index property, if found; - split probing code out of fsl_spi_init, thus we can call it for legacy device_type probing and new "compatible" probing.

| | | | | | | | | | | In case of QE we can use brg-frequency (which is qeclk/2). Thus no need to divide sysclk in the spi_mpc83xx. This patch also adds code to use get_brgfreq() on QE chips.
