Pull char/misc driver updates from Greg KH: "Here is the big set of char and misc and other tiny driver subsystem updates for 5.16-rc1. Loads of things in here, all of which have been in linux-next for a while with no reported problems (except for one called out below.) Included are: - habanana labs driver updates, including dma_buf usage, reviewed and acked by the dma_buf maintainers - iio driver update (going through this tree not staging as they really do not belong going through that tree anymore) - counter driver updates - hwmon driver updates that the counter drivers needed, acked by the hwmon maintainer - xillybus driver updates - binder driver updates - extcon driver updates - dma_buf module namespaces added (will cause a build error in arm64 for allmodconfig, but that change is on its way through the drm tree) - lkdtm driver updates - pvpanic driver updates - phy driver updates - virt acrn and nitr_enclaves driver updates - smaller char and misc driver updates" * tag 'char-misc-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc: (386 commits) comedi: dt9812: fix DMA buffers on stack comedi: ni_usb6501: fix NULL-deref in command paths arm64: errata: Enable TRBE workaround for write to out-of-range address arm64: errata: Enable workaround for TRBE overwrite in FILL mode coresight: trbe: Work around write to out of range coresight: trbe: Make sure we have enough space coresight: trbe: Add a helper to determine the minimum buffer size coresight: trbe: Workaround TRBE errata overwrite in FILL mode coresight: trbe: Add infrastructure for Errata handling coresight: trbe: Allow driver to choose a different alignment coresight: trbe: Decouple buffer base from the hardware base coresight: trbe: Add a helper to pad a given buffer area coresight: trbe: Add a helper to calculate the trace generated coresight: trbe: Defer the probe on offline CPUs coresight: trbe: Fix incorrect access of the sink specific data coresight: etm4x: Add ETM PID for Kryo-5XX coresight: trbe: Prohibit trace before disabling TRBE coresight: trbe: End the AUX handle on truncation coresight: trbe: Do not truncate buffer on IRQ coresight: trbe: Fix handling of spurious interrupts ...

dma-buf: move dma-buf symbols into the DMA_BUF module namespace

2021-10-25T12:53:08+00:00

In order to better track where in the kernel the dma-buf code is used, put the symbols in the namespace DMA_BUF and modify all users of the symbols to properly import the namespace to not break the build at the same time. Now the output of modinfo shows the use of these symbols, making it easier to watch for users over time: $ modinfo drivers/misc/fastrpc.ko | grep import import_ns: DMA_BUF Cc: "Pan, Xinhui" Cc: David Airlie Cc: Maarten Lankhorst Cc: Maxime Ripard Cc: Thomas Zimmermann Cc: Mauro Carvalho Chehab Cc: dri-devel@lists.freedesktop.org Acked-by: Daniel Vetter Acked-by: Christian König Acked-by: Arnd Bergmann Acked-by: Sumit Semwal Acked-by: Alex Deucher Link: https://lore.kernel.org/r/20211010124628.17691-1-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman

drm/omap: Depend on CONFIG_OF

2021-10-07T02:42:16+00:00

The driver accesses the drm_bridge.of_node field, which is present only if CONFIG_OF is enabled. As all platforms using omapdrm are OF-based, we can simply depend on CONFIG_OF. Signed-off-by: Laurent Pinchart Reviewed-by: Daniel Vetter

drm/omap: Cast pointer to integer without generating warning

2021-10-07T02:42:15+00:00

On 64-bit platforms, the compiler complains that casting a void pointer to an unsigned int loses data. Cast the pointer to a uintptr_t to fix this. Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen

drm/omap: Use correct printk format specifiers for size_t

2021-10-07T02:42:14+00:00

The correct format specifier for size_t is %zu. Using %d (or %u) generates a warning on 64-bit platforms. Fix it. Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen

drm: omap: remove obsolete selection of OMAP2_DSS in config DRM_OMAP

2021-08-26T09:19:08+00:00

Commit 55b68fb856b5 ("drm/omap: squash omapdrm sub-modules into one") removes the config OMAP2_DSS in ./drivers/gpu/drm/omapdrm/dss/Kconfig, while moving the other configs into./drivers/gpu/drm/omapdrm/Kconfig, but misses to remove an obsolete selection of OMAP2_DSS in config DRM_OMAP. Hence, ./scripts/checkkconfigsymbols.py warns: OMAP2_DSS Referencing files: drivers/gpu/drm/omapdrm/Kconfig Remove this reference in an obsolete selection.

drm/bridge: Centralize error message when bridge attach fails

2021-07-28T13:33:12+00:00

Being informed of a failure to attach a bridge is useful, and many drivers prints an error message in that case. Move the message to drm_bridge_attach() to avoid code duplication. Suggested-by: Stephen Boyd Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Reviewed-by: Jyri Sarha

drm/omapdrm: Remove outdated comment

2021-07-15T09:24:53+00:00

The comment refers to drm_irq_install() et al, which are not used by omapdrm. The functions are part of the DRM IRQ midlayer and shouldn't be used any longer. Remove the comment.

drm/omapdrm: Track IRQ state in local device state

2021-06-29T09:08:43+00:00

Replace usage of struct drm_device.irq_enabled with the driver's own state field struct omap_drm_device.irq_enabled. The field in the DRM device structure is considered legacy and should not be used by KMS drivers.

drm/omap: Follow implicit fencing in prepare_fb

I guess no one ever tried running omap together with lima or panfrost, not even sure that's possible. Anyway for consistency, fix this.
