From 5c5cbb53a4fd2f7d2a7038b584f8ee01266cef04 Mon Sep 17 00:00:00 2001 From: Zong Li Date: Fri, 15 Apr 2022 02:24:20 +0000 Subject: lib: utils/serial: support 'reg-offset' property reg-offset property is used for offset to apply to the mapbase from the start of the registers in 8250 UART. In Linux kernel, it has been handled in 8250 UART driver. dt-bindings: /Documentation/devicetree/bindings/serial/8250.yaml Signed-off-by: Zong Li Reviewed-by: Anup Patel --- platform/fpga/ariane/platform.c | 4 +++- platform/fpga/openpiton/platform.c | 4 +++- 2 files changed, 6 insertions(+), 2 deletions(-) (limited to 'platform/fpga') diff --git a/platform/fpga/ariane/platform.c b/platform/fpga/ariane/platform.c index c6f0ffd..3fdc03b 100644 --- a/platform/fpga/ariane/platform.c +++ b/platform/fpga/ariane/platform.c @@ -23,6 +23,7 @@ #define ARIANE_UART_BAUDRATE 115200 #define ARIANE_UART_REG_SHIFT 2 #define ARIANE_UART_REG_WIDTH 4 +#define ARIANE_UART_REG_OFFSET 0 #define ARIANE_PLIC_ADDR 0xc000000 #define ARIANE_PLIC_NUM_SOURCES 3 #define ARIANE_HART_COUNT 1 @@ -92,7 +93,8 @@ static int ariane_console_init(void) ARIANE_UART_FREQ, ARIANE_UART_BAUDRATE, ARIANE_UART_REG_SHIFT, - ARIANE_UART_REG_WIDTH); + ARIANE_UART_REG_WIDTH, + ARIANE_UART_REG_OFFSET); } static int plic_ariane_warm_irqchip_init(int m_cntx_id, int s_cntx_id) diff --git a/platform/fpga/openpiton/platform.c b/platform/fpga/openpiton/platform.c index 59c6702..15e289a 100644 --- a/platform/fpga/openpiton/platform.c +++ b/platform/fpga/openpiton/platform.c @@ -22,6 +22,7 @@ #define OPENPITON_DEFAULT_UART_BAUDRATE 115200 #define OPENPITON_DEFAULT_UART_REG_SHIFT 0 #define OPENPITON_DEFAULT_UART_REG_WIDTH 1 +#define OPENPITON_DEFAULT_UART_REG_OFFSET 0 #define OPENPITON_DEFAULT_PLIC_ADDR 0xfff1100000 #define OPENPITON_DEFAULT_PLIC_NUM_SOURCES 2 #define OPENPITON_DEFAULT_HART_COUNT 3 @@ -127,7 +128,8 @@ static int openpiton_console_init(void) uart.freq, uart.baud, OPENPITON_DEFAULT_UART_REG_SHIFT, - OPENPITON_DEFAULT_UART_REG_WIDTH); + OPENPITON_DEFAULT_UART_REG_WIDTH, + OPENPITON_DEFAULT_UART_REG_OFFSET); } static int plic_openpiton_warm_irqchip_init(int m_cntx_id, int s_cntx_id) -- cgit v1.1
