2019-10-06net: stmmac: selftests: Fix L2 Hash Filter testJose Abreu
With the current MAC addresses hard-coded in the test we can get some false positives as we use the Hash Filtering method. Let's change the MAC addresses in the tests to be unique when hashed.

2019-10-04net: phy: at803x: use operating parameters from PHY-specific statusRussell King
Read the PHY-specific status register for the current operating mode (speed and duplex) of the PHY. This register reflects the actual mode that the PHY has resolved depending on either the advertisements of autoneg is enabled, or the forced mode if autoneg is disabled. This ensures that phylib's software state always tracks the hardware state. It seems both AR8033 (which uses the AR8031 ID) and AR8035 support this status register. AR8030 is not known at the present time. This patch depends on "net: phy: extract pause mode" and "net: phy: extract link partner advertisement reading".

2019-10-04net: phy: fix write to mii-ctrl1000 registerRussell King
When userspace writes to the MII_ADVERTISE register, we update phylib's advertising mask and trigger a renegotiation. However, writing to the MII_CTRL1000 register, which contains the gigabit advertisement, does neither. This can lead to phylib's copy of the advertisement becoming de-synced with the values in the PHY register set, which can result in incorrect negotiation resolution.

2019-10-04net: phy: allow for reset line to be tied to a sleepy GPIO controllerAndrea Merello
mdio_device_reset() makes use of the atomic-pretending API flavor for handling the PHY reset GPIO line. I found no hint that mdio_device_reset() is called from atomic context and indeed it uses usleep_range() since long time, so I would assume that it is OK to sleep there. This patch switch to gpiod_set_value_cansleep() in mdio_device_reset(). This is relevant if e.g. the PHY reset line is tied to a I2C GPIO controller. This has been tested on a ZynqMP board running an upstream 4.19 kernel and then hand-ported on current kernel tree.

2019-10-03Revert "drm/i915: Fix DP-MST crtc_mask"Ville Syrjälä
This reverts commit 4eaceea3a00f8e936a7f48dcd0c975a57f88930f. Several userspace clients (modesetting ddx and mutter+wayland at least) handle encoder.possible_crtcs incorrectly. What they essentially do is the following: possible_crtcs = ~0; for_each_possible_encoder(connector) possible_crtcs &= encoder->possible_crtcs; Ie. they calculate the intersection of the possible_crtcs for the connector when they really should be calculating the union instead. In our case each MST encoder now has just one unique bit set, and so the intersection is always zero. The end result is that MST connectors can't be lit up because no crtc can be found to drive them. I've submitted a fix for the modesetting ddx [1], and complained on #wayland about mutter, so hopefully the situation will improve in the future. In the meantime we have regression, and so must go back to the old way of misconfiguring possible_crtcs in the kernel.

2019-10-03drm/omap: fix max fclk divider for omap36xxTomi Valkeinen
The OMAP36xx and AM/DM37x TRMs say that the maximum divider for DSS fclk (in CM_CLKSEL_DSS) is 32. Experimentation shows that this is not correct, and using divider of 32 breaks DSS with a flood or underflows and sync losts. Dividers up to 31 seem to work fine. There is another patch to the DT files to limit the divider correctly, but as the DSS driver also needs to know the maximum divider to be able to iteratively find good rates, we also need to do the fix in the DSS driver.

2019-10-02drm/i915/dp: Fix dsc bpp calculations, v5.Maarten Lankhorst
There was a integer wraparound when mode_clock became too high, and we didn't correct for the FEC overhead factor when dividing, with the calculations breaking at HBR3. As a result our calculated bpp was way too high, and the link width limitation never came into effect. Print out the resulting bpp calcululations as a sanity check, just in case we ever have to debug it later on again. We also used the wrong factor for FEC. While bspec mentions 2.4%, all the calculations use 1/0.972261, and the same ratio should be applied to data M/N as well, so use it there when FEC is enabled. This fixes the FIFO underrun we are seeing with FEC enabled. Changes since v2: - Handle fec_enable in intel_link_compute_m_n, so only data M/N is adjusted. (Ville) - Fix initial hardware readout for FEC. (Ville) Changes since v3: - Remove bogus fec_to_mode_clock. (Ville) Changes since v4: - Use the correct register for icl. (Ville) - Split hw readout to a separate patch.

2019-10-02net: stmmac: Avoid deadlock on suspend/resumeThierry Reding
The stmmac driver will try to acquire its private mutex during suspend via phylink_resolve() -> stmmac_mac_link_down() -> stmmac_eee_init(). However, the phylink configuration is updated with the private mutex held already, which causes a deadlock during suspend. Fix this by moving the phylink configuration updates out of the region of code protected by the private mutex.

2019-10-02timer-of: don't use conditional expression with mixed 'void' typesLinus Torvalds
Randy Dunlap reports on the sparse list that sparse warns about this expression: of_irq->percpu ? free_percpu_irq(of_irq->irq, clkevt) : free_irq(of_irq->irq, clkevt); and honestly, sparse is correct to warn. The return type of free_percpu_irq() is 'void', while free_irq() returns a 'const void *' that is the devname argument passed in to the request_irq(). You can't mix a void type with a non-void types in a conditional expression according to the C standard. It so happens that gcc seems to accept it - and the resulting type of the expression is void - but there's really no reason for the kernel to have this kind of non-standard expression with no real upside. The natural way to write that expression is with an if-statement: if (of_irq->percpu) free_percpu_irq(of_irq->irq, clkevt); else free_irq(of_irq->irq, clkevt); which is more legible anyway. I'm not sure why that timer-of code seems to have this odd pattern. It does the same at allocation time, but at least there the types match, and it makes sense as an expression.
