20180731 changes v7: - imx-mailbox & DT: rework driver from 4 channel bidirectional mode to 16 channel unidirectional mode. 8 extra channels are implemented on top of General Purpose Interrupt bits provided by this MU. 20180726 changes v7: - DT: add i.MX6SX and i.MX7S to the documentation. - imx-mailbox: don't use devm_ functions for startup and shutdown. - imx-mailbox: rename imx_mu_rmw to imx_mu_xcr_rmw and add locks - imx-mailbox: pass of_property_read_bool directly to side_b 20180722 changes v6: - include one more patch provided by Aisheng - DT: add fall back compatible fsl,imx6sx-mu - imx-mailbox: for now, use only fsl,imx6sx-mu 20180721 changes v5: - DT: revert most of the changes from previous version - imx-mailbox: remove struct imx_mu_cfg - imx-mailbox: remove !! from imx_mu_last_tx_done() 20180718 changes v4: - DT: change fsl,mu-side-a to fsl,mu-side-b - DT: split the patches. - DT: add all currently known SoCs. - imx-mailbox: free allocated irq name on channel shutdown - imx-mailbox: rename *_imx7 functions to *_generic 20180715 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_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.
