2019-07-15net: mscc: refactor mscc_miimHoratiu Vultur
Because all MSCC SoC use the same MDIO bus, put the implementation in one common file(mscc_miim) and make all the other MSCC network drivers to use these functions.

2019-07-15net: mscc: serval: Remove delay when serdes is configuredHoratiu Vultur
When serdes configuration was written in hardware there was a delay of 100ms to be sure that configuration was written. But the delay is not needed because already the function serdes_write it is checking that the operation finished. Therefore remove the mdelay. This improves the speed of configuring the network driver.

2019-07-15net: phy: ti: Fix clock output DT propertyTrent Piepho
The code block reading the DT property for the clock output control was before the phy's DT node pointer was set, so it could never work. Move it after the node pointer is set. Also store the unsigned 32-bit property into an unsigned value, not a signed value, as the former will cause a problem if value overflows. For instance, if one were to add 0xffffffff as a code to mean the clock output should be turned off.

2019-07-15net: phy: ti: Use default values for tx/rx delay and fifo sizeTrent Piepho
When not using DM_ETH, these PHY settings are programmed with default values hardcoded into the driver. When using DM_ETH, they should come from the device tree. However, if the device tree does not have the properties, the driver will silent use -1. Which is entirely out of range, programs nonsense into the PHY's registers, and does not work. Change this to use the same defaults as non-DM_ETH if the device tree is lacking the properties. As an alternative, the kernel driver for the phy will display an error message and fail if the device tree is lacking.

2019-07-15mmc: do not change mode when accessing a boot partitionJean-Jacques Hiblot
Accessing the boot partition had been error prone with HS200 and HS400 and was disabled. The driver first switched to a lesser mode and then switched the partition access. It was mostly due to a bad handling of the switch and has been fixed, so let's remove this 'feature' Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-07-15mmc: During a switch, poll on dat0 if available and check the final statusJean-Jacques Hiblot
The switch operation can sometimes make the bus unreliable, in that case the send_status parameter should be false to indicate not to poll using CMD13. If polling on dat0 is possible, we should use it to detect the end of the operation. At the end of the operation it is safe to use CMD13 to get the status of the card. It is important to do so because the operation may have failed. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2019-07-15mmc: When switching partition, use the timeout specified in the ext_csdJean-Jacques Hiblot
The e-MMC spec allows the e-MMC to specify a timeout for the partition switch command. It can take up to 2550 ms. There is no lower limit to this value in the spec, but do as the the linux driver does and force it to be at least 300ms. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>

2019-07-15mmc: if possible, poll the busy state using DAT0Jean-Jacques Hiblot
Using the DAT0 line as a rdy/busy line is an alternative to reading the status register of the card. It especially useful in situation where the bus is not in a good shape, like when modes are switched. This is also how the linux driver behaves. Note of warning: As per the specification, while polling on DAT0 the CLK must not turned off: "[...] Without a clock edge the Device (unless previously disconnected by a deselect command (CMD7)) will force the DAT0 line down, forever.

It sometimes happen that the PSTATE register does not indicate that the bus is ready when it really is. This usually happens after a mode switch.
