Merge tag 'qcom-drivers-for-6.18-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
More Qualcomm device driver updates for v6.18
Introduce support for loading firmware into the QUP serial engines from
Linux, which allows deferring selection of which protocol (uart, i2c,
spi, etc) a given SE should have until the OS loads.
Also introduce the "object invoke" interface in the SCM driver, to
provide interface to the Qualcomm TEE driver.
