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_MXC instead of SOX_IMX7 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.
