2016-12-08clk: bcm: Support rate change propagation on bcm2835 clocksBoris Brezillon
Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set to a precise rate (in our case 108MHz). With the current implementation, where peripheral clocks are not allowed to forward rate change requests to their parents, it is impossible to match this requirement unless the bootloader has configured things correctly, or a specific rate has been assigned through the DT (with the assigned-clk-rates property). Add a new field to struct bcm2835_clock_data to specify which parent clocks accept rate change propagation, and support set rate propagation in bcm2835_clock_determine_rate().

2016-12-08clk: ti: omap36xx: Work around sprz319 advisory 2.1Richard Watts
The OMAP36xx DPLL5, driving EHCI USB, can be subject to a long-term frequency drift. The frequency drift magnitude depends on the VCO update rate, which is inversely proportional to the PLL divider. The kernel DPLL configuration code results in a high value for the divider, leading to a long term drift high enough to cause USB transmission errors. In the worst case the USB PHY's ULPI interface can stop responding, breaking USB operation completely. This manifests itself on the Beagleboard xM by the LAN9514 reporting 'Cannot enable port 2. Maybe the cable is bad?' in the kernel log. Errata sprz319 advisory 2.1 documents PLL values that minimize the drift. Use them automatically when DPLL5 is used for USB operation, which we detect based on the requested clock rate. The clock framework will still compute the PLL parameters and resulting rate as usual, but the PLL M and N values will then be overridden. This can result in the effective clock rate being slightly different than the rate cached by the clock framework, but won't cause any adverse effect to USB operation.

2016-12-08firmware: Correct handling of fw_state_wait() return valueBjorn Andersson
When request_firmware() finds an already open firmware object it will wait for that object to become fully loaded and then check the status. As __fw_state_wait_common() succeeds the timeout value returned will be truncated in _request_firmware_prepare() and interpreted as -EPERM. Prior to "firmware: do not use fw_lock for fw_state protection" the code did test if we where in the "done" state before sleeping, causing this particular code path to succeed, in some cases. As the callers are interested in the result of the wait and not the remaining timeout the return value of __fw_state_wait_common() is changed to signal "done" or "error", which simplifies the logic in _request_firmware_load() as well.

Document when the "detach" handler function pointed to by the `detach` member of a `struct comedi_driver` is called by the comedi core, and how the "attach" and "auto_attach" handlers can defer clean-up to it when they return an error to the comedi core. This is already mentioned as part of the documentation for `comedi_auto_config()`, but is useful to document it for `struct comedi_driver` as well, since `comedi_auto_config()` is not usually called directly by low-level comedi drivers, and it is not called at all for "legacy" comedi devices that are configured manually.

2016-12-08mlx4: xdp: Allow raising MTU up to one page minus eth and vlan hdrsMartin KaFai Lau
When XDP is active in mlx4, mlx4 is using one page/pkt. At the same time (i.e. when XDP is active), it is currently limiting MTU to be FRAG_SZ0 - ETH_HLEN - (2 * VLAN_HLEN) which is 1514 in x86. AFAICT, we can at least raise the MTU limit up to PAGE_SIZE - ETH_HLEN - (2 * VLAN_HLEN) which this patch is doing. It will be useful in the next patch which allows XDP program to extend the packet by adding new header(s). Note: In the earlier XDP patches, there is already existing guard to ensure the page/pkt scheme only applies when XDP is active in mlx4.

2016-12-08bpf: xdp: Allow head adjustment in XDP progMartin KaFai Lau
This patch allows XDP prog to extend/remove the packet data at the head (like adding or removing header). It is done by adding a new XDP helper bpf_xdp_adjust_head(). It also renames bpf_helper_changes_skb_data() to bpf_helper_changes_pkt_data() to better reflect that XDP prog does not work on skb. This patch adds one "xdp_adjust_head" bit to bpf_prog for the XDP-capable driver to check if the XDP prog requires bpf_xdp_adjust_head() support. The driver can then decide to error out during XDP_SETUP_PROG.

To be backwards compatible, snps,pbl will still be valid, but snps,txpbl/snps,rxpbl will override the value in snps,pbl if set. If the IP is synthesized to use the AXI interface, there is a register and a matching DT property inside the optional stmmac-axi-config DT node for controlling burst lengths, named snps,blen. However, using this register, it is not possible to control tx and rx independently. Also, this register is not available if the IP was synthesized with, e.g., the AHB interface.

2016-12-08net: stmmac: stmmac_platform: fix parsing of DT bindingNiklas Cassel
commit 64c3b252e9fc ("net: stmmac: fixed the pbl setting with DT") changed the parsing of the DT binding. Before 64c3b252e9fc, snps,fixed-burst and snps,mixed-burst were parsed regardless if the property snps,pbl existed or not. After the commit, fixed burst and mixed burst are only parsed if snps,pbl exists. Now when snps,aal has been added, it too is only parsed if snps,pbl exists. Since the DT binding does not specify that fixed burst, mixed burst or aal depend on snps,pbl being specified, undo changes introduced by 64c3b252e9fc. The issue commit 64c3b252e9fc ("net: stmmac: fixed the pbl setting with DT") tries to address is solved in another way: The databook specifies that all values other than 1, 2, 4, 8, 16, or 32 results in undefined behavior, so snps,pbl = <0> is invalid. If pbl is 0 after parsing, set pbl to DEFAULT_DMA_PBL. This handles the case where the property is omitted, and also handles the case where the property is specified without any data.

The calculation of SPR and SPPR doesn't round correctly at several places which might result in baud rates that are too big. For example with tclk_hz = 250000001 and target rate 25000000 it determined a divider of 10 which is wrong. Instead of fixing all the corner cases replace the calculation by an algorithm without a loop which should even be quicker to execute apart from being correct.
