git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull Devicetree updates from Rob Herring: "A bit bigger than normal as I've been busy this cycle. There's a few things with dependencies and a few things subsystem maintainers didn't pick up, so I'm taking them thru my tree. The fixes from Johan didn't get into linux-next, but they've been waiting for some time now and they are what's left of what subsystem maintainers didn't pick up. Summary: - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4 - Work to get rid of direct accesses to struct device_node name and type pointers in preparation for removing them. New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code. This makes the support more uniform and enables building all dtbs on c6x, microblaze, and powerpc. - Various DT binding updates for Renesas r8a7744 SoC - Vendor prefixes for Facebook, OLPC - Restructuring of some ARM binding docs moving some peripheral bindings out of board/SoC binding files - New "secure-chosen" binding for secure world settings on ARM - Dual licensing of 2 DT IRQ binding headers" * tag 'devicetree-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (78 commits) ARM: dt: relicense two DT binding IRQ headers power: supply: twl4030-charger: fix OF sibling-node lookup NFC: nfcmrvl_uart: fix OF child-node lookup net: stmmac: dwmac-sun8i: fix OF child-node lookup net: bcmgenet: fix OF child-node lookup drm/msm: fix OF child-node lookup drm/mediatek: fix OF sibling-node lookup of: Add missing exports of node name compare functions dt-bindings: Add OLPC vendor prefix dt-bindings: misc: bk4: Add device tree binding for Liebherr's BK4 SPI bus dt-bindings: thermal: samsung: Add SPDX license identifier dt-bindings: clock: samsung: Add SPDX license identifiers dt-bindings: timer: ostm: Add R7S9210 support dt-bindings: phy: rcar-gen2: Add r8a7744 support dt-bindings: can: rcar_can: Add r8a7744 support dt-bindings: timer: renesas, cmt: Document r8a7744 CMT support dt-bindings: watchdog: renesas-wdt: Document r8a7744 support dt-bindings: thermal: rcar: Add device tree support for r8a7744 Documentation: dt: Add binding for /secure-chosen/stdout-path dt-bindings: arm: zte: Move sysctrl bindings to their own doc ...
2018-10-23drm/msm: fix OF child-node lookupJohan Hovold1-2/+3
Use the new of_get_compatible_child() helper to lookup the legacy pwrlevels child node instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-child) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the probed device's node). While at it, also fix the related child-node reference leak.

2018-10-07drm/msm: dpu: Fix memory leak caused by dropped referenceSean Paul1-3/+1
We are currently leaking a drm_crtc_commit struct for every atomic commit containing plane state. The dpu plane destroy function cleans up the fb reference manually, but fails to release the commit ref. As a result, we just keep allocating drm_crtc_commits without ever freeing them. Fortunately there's a helper function which will clean up all of our mess at once, so use that. Thanks to Doug Anderson for reporting the memory leak (and leaving breadcrumbs from kmemleak!).

2018-10-06treewide: Replace more open-coded allocation size multiplicationsKees Cook1-2/+2
As done treewide earlier, this catches several more open-coded allocation size calculations that were added to the kernel during the merge window. This performs the following mechanical transformations using Coccinelle: kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...) kvzalloc(a * b, ...) -> kvcalloc(a, b, ...) devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

2018-10-04drm/msm/a6xx: Add devfreq support for a6xxSharat Masetty4-5/+67
Implement routines to estimate GPU busy time and fetching the current frequency for the polling interval. This is required by the devfreq framework which recommends a frequency change if needed. The driver code then tries to set this new frequency on the GPU by sending an Out Of Band(OOB) request to the GMU.

2018-10-04drm/msm: re-factor devfreq codeSharat Masetty3-23/+41
The devfreq framework requires the drivers to provide busy time estimations. The GPU driver relies on the hardware performance counteres for the busy time estimations, but different hardware revisions have counters which can be sourced from different clocks. So the busy time estimation will be target dependent. Additionally on targets where the clocks are completely controlled by the on chip microcontroller, fetching and setting the current GPU frequency will be different. This patch aims to embrace these differences by re-factoring the devfreq code a bit. Signed-off-by: Sharat Masetty <smasetty@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

2018-10-04drm/msm: suspend devfreq on initSharat Masetty1-0/+2
Devfreq turns on and starts recommending power level as soon as it is initialized. The GPU is still not powered on by the time the devfreq init happens and this leads to problems on GPU's where register access is needed to get/set power levels. So we start suspended and only restart devfreq when GPU is powered on. Signed-off-by: Sharat Masetty <smasetty@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
2018-10-04drm/msm/a6xx: Add inactive_period for a6xxJordan Crouse1-0/+1
The target definition for a630 didn't set a reasonable value for inactive_period so it defaulted to zero and we were essentially powering down after every submission.

2018-10-04drm/msm/a6xx: Poll for HFI responsesJordan Crouse3-120/+57
The only HFI communication with the GMU on sdm845 happens during initialization and all commands are synchronous.

2018-10-04msm/gpu/a6xx: Force of_dma_configure to setup DMA for GMUJordan Crouse1-1/+1
The point of the 'force_dma' parameter for of_dma_configure is to force the device to be set up even if DMA capability is not described by the firmware which is exactly the use case we have for GMU - we need SMMU to get set up but we have no other dma capabilities since memory is managed by the GPU driver. Currently we pass false so of_dma_configure() fails and subsequently GMU and GPU probe does as well.

2018-10-04drm/msm/a6xx: Fix PDC register overlapJordan Crouse3-69/+78
The current design greedily takes a big chunk of the PDC register space instead of just the GPU specific sections which conflicts with other drivers and generally makes a mess of things. Furthermore we only need to map the GPU PDC sections just once during init so map the memory inside the function that uses it and adjust the pointers and register offsets accordingly.

2018-10-04drm/msm: dpu: Consolidate atomic_check functions()Sean Paul1-13/+2
dpu_plane_atomic_check() is a very thin wrapper around dpu_plane_sspp_atomic_check(). All it does is a NULL-check of state->fb, which is already done by drm_atomic_helper_check_plane_state(). Further, the helper sets state->visible = false when this is true. So remove dpu_plane_atomic_check() and just use dpu_plane_sspp_atomic_check() directly.

2018-10-04drm/msm: dpu: Move atomic_check_plane_state() call to atomic_checkSean Paul1-40/+17
src/dst rects are checked in both atomic_check and atomic_update, with the more comprehensive check occurring in atomic_update, which is backwards. So consolodate the checks in atomic_check.

2018-10-04drm/msm: dpu: Remove impossible checksSean Paul1-18/+1
This patch removes some checks which are impossible to hit. As a result, we can move some of the local var assignments into the declarations.

2018-10-04drm/msm/dpu: remove RM topology definitionJeykumar Sankaran7-124/+52
RM maintained a redundant definition for display topology to identify the no. of hw blocks needed for a display and their hardware dependencies. This information can be implicitly deduced from the msm_display_topology structure available in RM reserve request. In addition to getting rid of the redundant topology, this change also removes the topology name enums and their usages. changes in v4: - remove the topology name enum entirely (Sean) changes in v5: - remove RM topology definition and their references (Sean) - Implement helper for dual mixer CRTC (Sean) changes in v6: - avoid heap memory for topology (Sean) Signed-off-by: Jeykumar Sankaran <jsanka@codeaurora.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Signed-off-by: Rob Clark <robdclark@gmail.com>
