If anyone has any objections, please let me know. ------------------ From: Adam Ford [ Upstream commit 11729caa520950e17cd81bc43ffc477c46cf791e ] Commit feaa8baee82a ("bus: ti-sysc: Implement SoC revision handling") created a list of SoC types searching for strings based on names and wildcards which associates the SoC to different families. The OMAP34xx and OMAP35xx are treated as SOC_3430 while OMAP36xx and OMAP37xx are treated as SOC_3630, but the AM35xx isn't listed. The AM35xx is mostly an OMAP3430, and a later commit a12315d6d270 ("bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific") looks for the SOC type and behaves in a certain way if it's SOC_3430. This caused a regression on the AM3517 causing it to return two errors: ti-sysc: probe of 48318000.target-module failed with error -16 ti-sysc: probe of 49032000.target-module failed with error -16 Fix this by treating the creating SOC_AM35 and inserting it between the SOC_3430 and SOC_3630. If it is treaed the same way as the SOC_3430 when checking the status of sysc_check_active_timer, the error conditions will disappear.
