| * fsl: Change fsl_phy_enet_if to phy_interface_tAndy Fleming2011-04-20-46/+49
| | | | | | | | | | | | | | | | | | | | | | | | The fsl_phy_enet_if enum was, essentially, the phy_interface_t enum. This meant that drivers which used fsl_phy_enet_if to deal with PHY interfaces would have to convert between the two (or we would have to have them mirror each other, and deal with the ensuing maintenance headache). Instead, we switch all clients of fsl_phy_enet_if over to phy_interface_t, which should become the standard, anyway.

| * phylib: Add a bunch of PHY drivers from tsecAndy Fleming2011-04-20-0/+1500
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tsec driver had a bunch of PHY drivers already written. This converts them all into PHY Lib drivers, and serves as the first set of PHY drivers for PHY Lib. While doing that, cleaned up a number of magic numbers (though not all of them, as PHY vendors like to keep their numbers as magical as possible). Also, noticed that almost all of the vitesse/cicada PHYs had the same config/parse/startup functions, so those have been collapsed into one.

| * Create PHY Lib for U-BootAndy Fleming2011-04-20-0/+831
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extends the mii_dev structure to participate in a full-blown MDIO and PHY driver scheme. The mii_dev structure and miiphy calls are modified in such a way to allow the original mii command and miiphy infrastructure to work as before, but also to support a new set of APIs which allow (among other things) sharing of PHY driver code and 10G support The mii command will continue to support normal PHY management functions (Clause 22 of 802.3), but will not be changed to support 10G (Clause 45). The basic design is similar to PHY Lib from Linux, but simplified for U-Boot's network and driver infrastructure. We now have MDIO drivers and PHY drivers An MDIO driver provides: read write reset A PHY driver provides: (optionally): probe config - initial setup, starting of auto-negotiation startup - waiting for AN, and reading link state shutdown - any cleanup needed The ethernet drivers interact with the PHY Lib using these functions: phy_connect() phy_config() phy_startup() phy_shutdown() Each PHY driver can be configured separately, or all at once using config_phylib_all_drivers.h (added in the patch which adds the drivers) We also provide generic drivers for Clause 22 (10/100/1000), and Clause 45 (10G) PHYs. We also implement phy_reset(), and call it in phy_connect(). Because phy_reset() is essentially the same as miiphy_reset, but: a) must support 10G PHYs, and b) should use the phylib primitives, we implement miiphy_reset, using phy_reset(), but only when CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this way, we save on compile size, even if we don't manage to save code size.

| * Remove instances of phy_read/writeAndy Fleming2011-04-20-107/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a few files which were already using phy_read and phy_write for their PHY function names. It's only a few places, and the name seems most appropriate for the high-level abstraction, so let's rename the other versions to something more specific. Also, uec_phy.c had a marvell_init function which I renamed to not conflict with the one in marvell.c Lastly, uec_phy.c was putting a space between the phy writing function names, and the open paren, so I fixed that Signed-off-by: Andy Fleming <afleming@freescale.com> Acked-by: Detlev Zundel <dzu@denx.de>

All ONFI revisions should be backwards-compatible; even if this is not the case on some newer ONFI revision, it should simply fail the second version-checking if-else block (i.e., the bit-fields for 1.0, 2.0, etc. would not be set to 1). Thus, we move our "unsupported" condition after having checked each bit field. Also, it's simple enough to add a condition for ONFI revision 2.3. Note that this does *NOT* mean we handle all new features of ONFI versions above 1.0.

| * | I2C: OMAP: detect more devices when probing an i2c busNick Thompson2011-04-14-31/+11
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The omap24xx driver only seems to support devices that have a single subaddress byte. With these types of devices, the first access in a bus transaction is usually a write (writes the subaddress) followed by either a read or write to access the devices registers. Many such devices will respond to a read as the first access, but there are at least some that will NACK such a read. (e.g. ADV7180.) The probe function attempts to detect a devices ACK to a read access only and fails to find devices that NACK a read. This commit modifies the probe function to start a write instead. This detects devices that respond to reads (since they must also respond to writes) as well as those that only respond to writes. The bus is immediately set to idle after a (N)ACK avoiding actually writing anything to the device. Signed-off-by: Nick Thompson <nick.thompson@ge.com>
