Subject: [PATCH v3 0/3] add mailbox support for i.MX7D

20180615 changes v3:
- DT: remove prosaic part of documentation. It describes software
  or firmware specific usage and not relevant for HW description.
- DT: use <soc>-mu instead of <soc>-mu-<mu side> and add fsl,mu-side-a
  parameter.
- DT: add most of know i.MX variants with MU
- imx-mailbox: use macros instead of precalculated bit index.
- imx-mailbox: remove warning message for clk.
- imx-mailbox: use imx_mu_chan[%idx] for devm_request_irq.
- imx-mailbox: depend on ARCH_MXS instead of SOX_IMX7

It's ARCH_MXC, but no affection on real patches.

Regards
Dong Aisheng

20180615 changes v2:
- DT: use mailbox@ instead of mu@
- DT: change interrupts description
- clk: use imx_clk_gate4 instead of imx_clk_gate2
- imx-mailbox: remove last_tx_done support
- imx-mailbox: fix module description

This patches are providing support for mailbox (Messaging Unit) for i.MX7D.
Functionality was tested on PHYTEC phyBOARD-Zeta i.MX7D with Linux
running on all cores: ARM Cortex-A7 and ARM Cortex-M4.

Both parts of i.MX messaging Unit are visible for all CPUs available on i.MX7D.
Communication worked independent of MU side in combination with CPU.
For example MU-A used on ARM Cortex-A7 and MU-B used on ARM Cortex-
M4 or other ways around.
