commit: c281634c865202e2776b0250678ff93c771947ff ARM: compat: remove KERNEL_DS
usage in sys_oabi_epoll_ctl()
date: 10 months ago
config:
This patch set provides ACPI support to DPAA2 network drivers.
It also introduces new fwnode based APIs to support phylink and phy
layers
Following functions are defined:
phylink_fwnode_phy_connect()
fwnode_mdiobus_register_phy()
fwnode_mdiobus_register()
Introduce fwnode_mdiobus_register_phy() to register PHYs on the
mdiobus. From the compatible string, identify whether the PHY is
c45 and based on this create a PHY device instance which is
registered on the mdiobus.
uninitialized symbol 'mii_ts'
Reported-by: kernel test robot

Define acpi_mdiobus_register() to Register mii_bus and create PHYs for
each ACPI child node.

If only the dynamic part of procfs is mounted (subset=pid), then there is no
need to check if procfs is fully visible to the user in the new user namespace.
Changelog
-
v4:
* Set SB_I_DYNAMIC only if pidonly is set.
* Add an error message if subset=pid is canceled during remount.
v3:
*
Cache the mounters credentials and make access to the net directories
contingent of the permissions of the mounter of proc.
Show /proc/self/net only if mounter has CAP_NET_ADMIN and if proc is

This series implements support for the camera subsystem found in
the SDM845 SOCs and the Titan 170 ISP. The support is partial
in that it implements CSIPHY, CSID, and partial VFE support.
The Titan generation of the ISP diverges a fair amount from the
design of the previous architecture
Comment refers to ISPIF, but this is incorrect. Only
the VFE interrupts are handled by this function.

The CSI-2 spec defines the following types:

- Encode Format
These definitions are as far as I can tell complete for CSI-2.

This driver supports multiple architecture versions of the Qualcomm ISP.
The CAMSS architecure which this driver is name after, and with the
introduction of this series, the Titan architecture.
The ISPIF is an IP-block that is only present in the CAMSS generation of

The HEVC HANTRO driver needs to know the number of bits to skip at
the beginning of the slice header.
That is a hardware specific requirement so create a dedicated control

Implement all the logic to get G2 hardware decoding HEVC frames.

It doesn't support yet 10 bits formats or scaling feature.

Split VPU node in two: one for G1 and one for G2 since they are

Why are you adding this directly to drivers/staging/media/ and not
Add helper functions to allocate and free auxiliary buffers.
These buffers aren't for frames but are needed by the hardware
to store scaling matrix, tiles size, border filters etc...
