Subject: RE: [PATCH] serial: tegra: Map the iir register to default defines
Verification failed on Tegra.
Fix here is, IIR should be masked with UART_IIR_MASK after reading the IIR register as on Tegra bit-6 is used for internal usage to know if FIFO mode is enabled.
while (1) {
iir = tegra_uart_read(tup, UART_IIR);
+iir &= UART_IIR_MASK;
Thanks,
Shardar
