Merge tag 'mailbox-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/jassibrar/mailbox
Pull mailbox updates from Jassi Brar:
- fix kconfig dependencies (mhu-v3, omap2+)
- use devie name instead of genereic imx_mu_chan as interrupt name
(imx)
- enable sa8255p and qcs8300 ipc controllers (qcom)
- Fix timeout during suspend mode (bcm2835)
- convert to use use of_property_match_string (mailbox)
- enable mt8188 (mediatek)
- use devm_clk_get_enabled helpers (spreadtrum)
- fix device-id typo (rockchip)
