2018-03-13efi/libstub/tpm: Initialize pointer variables to zero for mixed modeArd Biesheuvel
As reported by Jeremy Cline, running the new TPM libstub code in mixed mode (i.e., 64-bit kernel on 32-bit UEFI) results in hangs when invoking the TCG2 protocol, or when accessing the log_tbl pool allocation. The reason turns out to be that in both cases, the 64-bit pointer variables are not fully initialized by the 32-bit EFI code, and so we should take care to zero initialize these variables beforehand, or we'll end up dereferencing bogus pointers.

2018-03-13drm/meson: Add support for DMT modes on HDMINeil Armstrong
This patch adds support for DMT display modes over HDMI. The modes timings configurations are from the Amlogic Vendor linux tree and tested over multiples monitors. Previously only a selected number of CEA modes were supported. Only these following modes are supported with these changes: - 640x480@60Hz - 800x600@60Hz - 1024x768@60Hz - 1152x864@75Hz - 1280x1024@60Hz - 1600x1200@60Hz - 1920x1080@60Hz The associated code to handle the clock rates is also added.

* 'clk-helpers' (early part): clk: fix determine rate error with pass-through clock
2018-03-12clk: fix determine rate error with pass-through clockJerome Brunet
If we try to determine the rate of a pass-through clock (a clock which does not implement .round_rate() nor .determine_rate()), clk_core_round_rate_nolock() will directly forward the call to the parent clock. In the particular case where the pass-through actually does not have a parent, clk_core_round_rate_nolock() will directly return 0 with the requested rate still set to the initial request structure. This is interpreted as if the rate could be exactly achieved while it actually cannot be adjusted. This become a real problem when this particular pass-through clock is the parent of a mux with the flag CLK_SET_RATE_PARENT set. The pass-through clock will always report an exact match, get picked and finally error when the rate is actually getting set. This is fixed by setting the rate inside the req to 0 when core is NULL in clk_core_round_rate_nolock() (same as in __clk_determine_rate() when hw is NULL) Fixes: 0f6cc2b8e94d ("clk: rework calls to round and determine rate callbacks") Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

Commit 19110cfbb34d ("e1000e: Separate signaling for link check/link up") changed what happens to the link status when there is an error which happens after "get_link_status = false" in the copper check_for_link callbacks. Previously, such an error would be ignored and the link considered up. After that commit, any error implies that the link is down. Revert commit 19110cfbb34d ("e1000e: Separate signaling for link check/link up") and its followups. After reverting, the race condition described in the log of commit 19110cfbb34d is reintroduced. It may still be triggered by LSC events but this should keep the link down in case the link is electrically unstable, as discussed. The race may no longer be triggered by RXO events because commit 4aea7a5c5e94 ("e1000e: Avoid receiver overrun interrupt bursts") restored reading icr in the Other handler.

However, if we only waited for a subset of the reservation object, i.e. just waiting for the last writer to complete as opposed to all readers as well, then we would erroneously conclude we could prune the fences as indeed although all of our waits were successful, they did not represent the totality of the reservation object. v2: We only need to check the shared fences due to construction (i.e. all of the shared fences will be later than the exclusive fence, if any).

2018-03-12clk: migrate the count of orphaned clocks at initJerome Brunet
The orphan clocks reparents should migrate any existing count from the orphan clock to its new acestor clocks, otherwise we may have inconsistent counts in the tree and end-up with gated critical clocks Assuming we have two clocks, A and B. * Clock A has CLK_IS_CRITICAL flag set. * Clock B is an ancestor of A which can gate. Clock B gate is left enabled by the bootloader. Step 1: Clock A is registered. Since it is a critical clock, it is enabled. The clock being still an orphan, no parent are enabled. Step 2: Clock B is registered and reparented to clock A (potentially through several other clocks). We are now in situation where the enable count of clock A is 1 while the enable count of its ancestors is 0, which is not good. Step 3: in lateinit, clk_disable_unused() is called, the enable_count of clock B being 0, clock B is gated and and critical clock A actually gets disabled. This situation was found while adding fdiv_clk gates to the meson8b platform. These clocks parent clk81 critical clock, which is the mother of all peripheral clocks in this system. Because of the issue described here, the system is crashing when clk_disable_unused() is called. The situation is solved by reverting commit f8f8f1d04494 ("clk: Don't touch hardware when reparenting during registration"). To avoid breaking again the situation described in this commit description, enabling critical clock should be done before walking the orphan list. This way, a parent critical clock may not be accidentally disabled due to the CLK_OPS_PARENT_ENABLE mechanism.

2018-03-12net: phy: Tell caller result of phy_change()Brad Mouring
In 664fcf123a30e (net: phy: Threaded interrupts allow some simplification) the phy_interrupt system was changed to use a traditional threaded interrupt scheme instead of a workqueue approach. With this change, the phy status check moved into phy_change, which did not report back to the caller whether or not the interrupt was handled. This means that, in the case of a shared phy interrupt, only the first phydev's interrupt registers are checked (since phy_interrupt() would always return IRQ_HANDLED). This leads to interrupt storms when it is a secondary device that's actually the interrupt source. Signed-off-by: Brad Mouring <brad.mouring@ni.com> Signed-off-by: David S.

2018-03-12drm/sun4i: Fix exclusivity of the TCON clocksOndrej Jirman
Currently the exclusivity is enabled when the rate is set by the mode setting functions. These functions are called by mode_set_nofb callback of drm_crc_helper. Then exclusivity is disabled when tcon is disabled by atomic_disable callback. What happens is that mode_set_nofb can be called once when mode changes, and afterwards the system can call atomic_enable and atomic_disable multiple times without further calls to mode_set_nofb. This happens: mode_set_nofb - clk exclusivity is enabled atomic_enable atomic_disable - clk exclusivity is disabled atomic_enable atomic_disable - clk exclusivity is already disabled, leading to WARN in clk_rate_exclusive_put Solution is to enable exclusivity in sun4i_tcon_channel_set_status.

2018-03-12can: ifi: Repair the error handlingMarek Vasut
The new version of the IFI CANFD core has significantly less complex error state indication logic. In particular, the warning/error state bits are no longer all over the place, but are all present in the STATUS register. Moreover, there is a new IRQ register bit indicating transition between error states (active/warning/passive/busoff). This patch makes use of this bit to weed out the obscure selective INTERRUPT register clearing, which was used to carry over the error state indication into the poll function. While at it, this patch fixes the handling of the ACTIVE state, since the hardware provides indication of the core being in ACTIVE state and that in turn fixes the state transition indication toward userspace. Finally, register reads in the poll function are moved to the matching subfunctions since those are also no longer needed in the poll function.
