| * 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.

| * commands: mem: truncate mem device size to fit the loff_t file sizeLucas Stach2018-11-071-1/+2
| | | | | | | | | | | | | | | | | | | | On 64bit arches the file covering the whole address space is larger than what can be represented in the loff_t type (s64) used for the file size. Thus the size of this device is interpreted as negative in a lot of places. Fix this by truncating the size to fit the file size type.

| * 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. (Tested on a Terasic DE0-Nano-SoC with a suitably modified device tree.) Signed-off-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * net: dhcp: fix option 54Marcin Niestroj2018-10-262-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Option 54 (Server Identifier) is something different than SIADDR (Server IP address). Currently they are used interchangeably. This causes DHCPNAK with DHCP servers that have configured different values for each field. Create new 'dhcp_serverip' field in 'struct dhcp_result', so we treat option 54 separately. This fixes DHCP requests for servers that send two different values for SIADDR and option 54 in DHCPOFFER.

| | | | | | | | | | | | | | | | | | In contrast to the ds1337 the ds3231 has a built-in temperature compensated crystal oscillator.

| * 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.
