Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote). Upstream: https://github.com/xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2)

/**

* struct caif_dev_common - data shared between CAIF drivers and stack.
|
|
* @flowctrl: Flow Control callback function. This function is
|
|
* supplied by CAIF Core Stack and is used by CAIF
|
|
* Link Layer to send flow-stop to CAIF Core.
|
|
* The flow information will be distributed to all
|
|
* clients of CAIF.
|
|
*
|
|
* @link_select: Profile of device, either high-bandwidth or
|
|
* low-latency. This member is set by CAIF Link
|
|
* Layer Device in order to indicate if this device
|
|
* is a high bandwidth or low latency device.
|
|
*
|
|
* @use_frag: CAIF Frames may be fragmented.
|
|
* Is set by CAIF Link Layer in order to indicate if the
|
|
* interface receives fragmented frames that must be
|
|
* assembled by CAIF Core Layer.
|
|
*
|
|
* @use_fcs: Indicate if Frame CheckSum (fcs) is used.
|
|
* Is set if the physical interface is
|
|
* using Frame Checksum on the CAIF Frames.
|
|
*
|
|
* @use_stx: Indicate STart of frame eXtension (stx) in use.
|
|
* Is set if the CAIF Link Layer expects
|
|
* CAIF Frames to start with the STX byte.
|
|
*
|
|
* This structure is shared between the CAIF drivers and the CAIF stack.
|
|
* It is used by the device to register its behavior.
|
|
* CAIF Core layer must set the member flowctrl in order to supply
|
|
* CAIF Link Layer with the flow control function.
