2022-06-06drm/mediatek: Add DSC support for mediatek-drmjason-jh.lin2-0/+48
DSC is designed for real-time systems with real-time compression, transmission, decompression and display. The DSC standard is a specification of the algorithms used for compressing and decompressing image display streams, including the specification of the syntax and semantics of the compressed video bit stream.

2022-06-06mtd: rawnand: meson: Fix a potential double free issueChristophe JAILLET1-1/+0
When meson_nfc_nand_chip_cleanup() is called, it will call: meson_nfc_free_buffer(&meson_chip->nand); nand_cleanup(&meson_chip->nand); nand_cleanup() in turn will call nand_detach() which calls the .detach_chip() which is here meson_nand_detach_chip(). meson_nand_detach_chip() already calls meson_nfc_free_buffer(), so we could double free some memory. Fix it by removing the unneeded explicit call to meson_nfc_free_buffer().

We tried to enable the audio on an imx6sx EVB with the codec nau8822, after setting the internal PLL fractional parameters, the audio still couldn't work and the there was no sdma irq at all. After checking with the section "8.1.1 Phase Locked Loop (PLL) Design Example" of "NAU88C22 Datasheet Rev 0.6", we found we need to turn off the PLL before programming fractional parameters and turn on the PLL after programming. After this change, the audio driver could record and play sound and the sdma's irq is triggered when playing or recording.

2022-06-06spi: spi.c: Convert statistics to per-cpu u64_stats_tDavid Jander2-68/+127
This change gives a dramatic performance improvement in the hot path, since many costly spin_lock_irqsave() calls can be avoided. On an i.MX8MM system with a MCP2518FD CAN controller connected via SPI, the time the driver takes to handle interrupts, or in other words the time the IRQ line of the CAN controller stays low is mainly dominated by the time it takes to do 3 relatively short sync SPI transfers. The effect of this patch is a reduction of this time from 136us down to only 98us.

2022-06-06spi: cadence-quadspi: Remove spi_master_put() in probe failure pathVaishnav Achath1-12/+7
Currently the spi_master is allocated by devm_spi_alloc_master() and devres core manages the deallocation, but in probe failure path spi_master_put() is being handled manually which causes "refcount underflow use-after-free" warning when probe failure happens after allocating spi_master. Trimmed backtrace during failure: refcount_t: underflow; use-after-free. pc : refcount_warn_saturate+0xf4/0x144 Call trace: refcount_warn_saturate kobject_put put_device devm_spi_release_controller devres_release_all This commit makes relevant changes to remove spi_master_put() from probe failure path.

2022-06-06spi: s3c64xx: requests spi-dma channel only during data transferAdithya K V1-24/+32
Current s3c64xx SPI driver acquires DMA channel during driver probe and holds on it even when channels are not used (no DMA transfer). This is a problem especially when all the DMA channels are exhausted (as other IPs on the same DMA controller also acquires DMA channel) and if a new IP/Device requests for a DMA channel (on the same DMA controller), it won’t get DMA channel allocated. The said issue can be avoided if s3c64xx driver request and release DMA channel before and after data transfer. Let’s modify the driver to request and release DMA channel before and after DMA mode data transfer.

2022-06-06spi: spi-altera-dfl: Fix an error handling pathChristophe JAILLET1-9/+5
The spi_alloc_master() call is not undone in all error handling paths. Moreover, there is no .remove function to release the allocated memory. In order to fix both this issues, switch to devm_spi_alloc_master(). This allows further simplification of the probe.
