CONFIG_UART_NS16550_PORT_1_PCP¶
Port 1 PCP value
Type: hex
Help¶
Value for PRV_CLOCK_PARAMS register. If left at its default value (0), then the kernel will not attempt to set the PCP for this UART; otherwise be sure the device tree for this port has sys_clk_freq set accordingly.
Direct dependencies¶

(Includes any dependencies from if’s and menus.)
