Subject: [PATCH v2 00/10] firmware: arm_scmi: Add support for Rx channels, async commands and delayed response

Hi,

This patch series adds SCMI infrastructure/core support for recieve(Rx)
channels, asynchronous commands and delayed response. It adds async
command support for clock rate setting and sensor reading based on the
attributes read from the firmware.

The code is rebased on the cleanup series[1] and is available @[2]

[2] git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git scmi_updates

v1->v2:
	- Fixed error messages to indicate Tx/Rx correctly
	- Dropped receive buffer support as notifications are not yet added
	- Simplied atomic_inc/dec for async request count and fixed the
	  commit message
	- Fixed fetching sensor value i.e. *pval + 1 to *(pval + 1) in
	  scmi_sensor_reading_get
