module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

Pull spi updates from Mark Brown: "The only real core work we've got this time around is the completion of the transition to the new host/target naming for the core APIs, Kconfig still needs doing but that's a lot less invasive. Otherwise the big changes are the new drivers that have been added: - Completion of the conversion to spi_alloc_host()/_target() and removal of the old naming. - Cleanups for Rockchip drivers, these brought in a new logging helper in the driver core for warnings during probe. - Support for configuration of the word delay via spidev_test. - Support for AMD HID2 controllers, Apple SPI controller and Realtek SPI-NAND controllers" * tag 'spi-v6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (58 commits) spi: imx: support word delay spi: imx: pass struct spi_transfer to prepare_transfer() spi: cs42l43: Add GPIO speaker id support to the bridge configuration spi: Delete useless checks spi: apple: Remove unnecessary .owner for apple_spi_driver spi: spidev_test: add support for word delay spi: apple: Add driver for Apple SPI controller spi: dt-bindings: apple,spi: Add binding for Apple SPI controllers spi: Use of_property_present() for non-boolean properties spi: zynqmp-gqspi: Undo runtime PM changes at driver exit time spi: spi-mem: rtl-snand: Correctly handle DMA transfers spi: tegra210-quad: Avoid shift-out-of-bounds spi: axi-spi-engine: Emit trace events for spi transfers dt-bindings: spi: sprd,sc9860-spi: convert to YAML spi: Replace deprecated PCI functions spi: dt-bindings: samsung: Add a compatible for samsung,exynos8895-spi spi: spi-mem: Add Realtek SPI-NAND controller dt-bindings: spi: Add realtek,rtl9301-snand spi: make class structs const spi: dt-bindings: brcm,bcm2835-aux-spi: Convert to dtschema ...

media: mgb4: Fix inconsistent input/output alignment in loopback mode

2024-11-08T12:38:09Z

Fixes broken output due to different input/output alignment in loopback mode when the (last) input device is closed. Instead of on device close, do the alignment synchronisation when starting the stream (and clear it when streaming is stopped). Signed-off-by: Martin Tůma Signed-off-by: Hans Verkuil

media: ipu6: make the ipu6_mmu_unmap() as a void function

2024-11-07T08:05:58Z

The DMA unmap API is not supposed to return value. Thus this patch changes the ipu6_mmu_unmap() as a void function and DMA unmapping didn't check the return value. Signed-off-by: Bingbu Cao [Sakari Ailus: Drop unnecessary returns.] Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil

media: ipu6: optimize the IPU6 MMU mapping flow

2024-11-07T08:05:58Z

ipu6_mmu_map() operated on a per-page basis, it leads frequent spin_lock/unlock() and clflush_cache_range() for each page, it will cause inefficiencies especially when handling dma-bufs with large number of pages. However, the pages are likely concentrated pages by IOMMU DMA driver, IPU MMU driver can map the concentrated pages into less entries in l1 table. This change enhances ipu6_mmu_map() with batching process multiple contiguous pages. It significantly reduces calls for spin_lock/unlock and clflush_cache_range() and improve the performance.
