media: v4l: Fix missing tabular column hint for Y14P format

2024-07-30T06:36:29Z

The original patch added two columns in the flat-table of Luma-Only Image Formats, without updating hints to latex: above it. This results in wrong column count in the output of Sphinx's latex builder. Fix it.

landlock: Various documentation improvements

2024-07-18T06:27:47Z

* Fix some typos, incomplete or confusing phrases. * Split paragraphs where appropriate. * List the same error code multiple times, if it has multiple possible causes. * Bring wording closer to the man page wording, which has undergone more thorough review (esp. for LANDLOCK_ACCESS_FS_WRITE_FILE). * Small semantic clarifications * Call the ephemeral port range "ephemeral" * Clarify reasons for EFAULT in landlock_add_rule() * Clarify @rule_type doc for landlock_add_rule() This is a collection of small fixes which I collected when preparing the corresponding man pages [1].

misc: mrvl-cn10k-dpi: add Octeon CN10K DPI administrative driver

2024-07-10T12:58:29Z

Adds a misc driver for Marvell CN10K DPI(DMA Engine) device's physical function which initializes DPI DMA hardware's global configuration and enables hardware mailbox channels between physical function (PF) and it's virtual functions (VF). VF device drivers (User space drivers) use this hw mailbox to communicate any required device configuration on it's respective VF device. Accordingly, this DPI PF driver provisions the VF device resources. At the hardware level, the DPI physical function (PF) acts as a management interface to setup the VF device resources, VF devices are only provisioned to handle or control the actual DMA Engine's data transfer capabilities.
