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.
