Vignesh, it seems this quirk needs some soc specific flag added to it maybe? Or maybe UART_OMAP_RX_LVL register is not available for all the SoCs?Yes indeed :(quoted
I think it's best to drop this patch until the issues are resolved, also there are some open comments above that might be answered by limiting this quirk to a specific range of SoCs :)Oops, I did test patch AM33xx assuming its equivalent to OMAP3, but UART IP is quite different. I will respin the patch making sure, workaround applies only to AM65x and K3 SoCs. Regards VigneshWhat's the status here for AM65x? The issue remains present on that platform, and I was hoping to see a quick follow up that limit the fix to that target.
Sorry for the delay, I am trying to find which other TI SoCs are affected by this issue. But that exercise will need a bit more time. Will send a fix to address K3 SoCs like AM65x today/tomo.
