Like i.MX8 SCU, i.MX8ULP S4 also has vendor specific protocol. - bind SCU/S4 MU part to share one tx/rx/init API to make code simple. - S4 msg max size is very large, so alloc the space at driver probe, not use local on stack variable. - S4 MU has 8 TR and 4 RR which is different with i.MX8 MU, so adapt code to reflect this. Tested on i.MX8MP, i.MX8ULP Signed-off-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Jassi Brar <jaswinder.singh@linaro.org>
