net: wwan: iosm: add rpc interface for xmm modems Add a new iosm wwan port that connects to the modem rpc interface. This interface provides a configuration channel, and in the case of the 7360, is the only way to configure the modem (as it does not support mbim). The new interface is compatible with existing software, such as open_xdatachannel.py from the xmm7360-pci project [1].

Revert "net: wwan: iosm: firmware flashing and coredump collection" The devlink parameters are not the right mechanism to pass extra parameters to device flashing. The params added are also undocumented. This reverts commit 13bb8429ca98 ("net: wwan: iosm: firmware flashing and coredump collection").

net: wwan: iosm: firmware flashing and coredump collection This patch brings-in support for M.2 7560 Device firmware flashing & coredump collection using devlink. - Driver Registers with Devlink framework. - Register devlink params callback for configuring device params required in flashing or coredump flow. - Implements devlink ops flash_update callback that programs modem firmware. - Creates region & snapshot required for device coredump log collection. On early detection of device in boot rom stage. Driver registers with Devlink framework and establish transport channel for PSI (Primary Signed Image) injection. Once PSI is injected to device, the device execution stage details are read to determine whether device is in flash or exception mode. The collected information is reported to devlink user space application & based on this informationi, application proceeds with either modem firmware flashing or coredump collection.

net: iosm: Prevent underflow in ipc_chnl_cfg_get() The bounds check on "index" doesn't catch negative values. Using ARRAY_SIZE() directly is more readable and more robust because it prevents negative values for "index". Fortunately we only pass valid values to ipc_chnl_cfg_get() so this patch does not affect runtime.
