| * | | mtd: nand: add accessors, macros for in-memory BBTLadislav Michl2018-10-261-22/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux commit 771c568bcf91: There is an abundance of magic numbers and complicated shifting/masking logic in the in-memory BBT code which makes the code unnecessary complex and hard to read. This patch adds macros to represent the 00b, 01b, 10b, and 11b memory-BBT magic numbers, as well as two accessor functions for reading and marking the memory-BBT bitfield for a given block.

| * | | ARM: clk: rk3188: don't set same clk rate twiceperachet7@gmail.com2018-11-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We found setting a clock rate which has already been set, rk3188 (radxa rock pro) bails out. This is a quick fix only. Underlying situation not (yet) investigated: why it is even trying to set it to the same rate again. It remains to state that some but not all rrpro boards exhibit this behaviour, no other rk3188 boards have been tested. Signed-off-by: P.

| * | | net: designware: look for a child device node for MDIO busIan Abbott2018-11-021-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Designware driver registers a local MDIO bus for each MAC device, but without setting a device node pointer for the MDIO bus device. In this case, mdiobus_register() will use the MDIO bus's parent device node (if any) as the MDIO device node. If the MAC device node has a child node compatible with "snps,dwmac-mdio", let us use that as the MDIO bus device node. Otherwise, leave the MDIO bus device node pointer set to NULL and carry on as before. The upshot is that PHY device nodes can now be placed in an intermediate node for the MDIO bus instead of having to place them directly in the Designware MAC device node.

| * | | phy: call adjust_link in attach if using fixed-linkClément Leger2018-10-161-0/+4
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, phy_update_status is in charge of reporting a change in link status when phy is updated. When using fixed-link, speed and duplex are initialized directly after registering the phy and there is no driver. Hence when phy_update_status is called, the check for new values fails and returns directly. Since update_link call is mandatory for some network devices to work, call it directly when using fixed link in phy_device_attach to force update of link.
