imx6 adds three serial ports

I am the development board of imx6q-sdb. Now I want to add three serial ports, namely UART2/UART4/UART5. I changed five files, namely board-mx6q_sabresd.h

, board-mx6q_sabresd.c, platform-imx-uart .c, clock.c, mx6.h modified as follows:

1.board-mx6q_sabresd.h
/ * * UART3 /
MX6Q_PAD_EIM_D26_UART2_TXD,
MX6Q_PAD_EIM_D27_UART2_RXD,

/ * * UART4 /
MX6Q_PAD_KEY_COL0_UART4_RXD,
MX6Q_PAD_KEY_ROW0_UART4_TXD,

/ * * of UART5 /
MX6Q_PAD_KEY_COL0_UART4_RXD,
MX6Q_PAD_KEY_ROW_UART4_TXD,

2.board -mx6q_sabresd.c

static inline void mx6q_sabresd_init_uart(void)
{
imx6q_add_imx_uart(0,NULL);
imx6q_add_imx_uart(1,NULL);
imx6q_add_imx_uart(2,NULL);
imx6q_add_imx_uart(3,NULL);
imx6q_add_imx_uart(4,NULL)
;

3.platform-imx-uart.c
#define imx6q_imx_uart_data_entry(_id, _hwid)
imx_imx_uart_lirq_data_entry(MX6Q, _id, _hwid, SZ_4K)
imx6q_imx_uart_data_entry(0,1),
imx6q_imx_uart_data_entry(1,2),
imx6q_imx_uart_data_entry(2,3),
imx6q_imx_uart_data_entry(3,4),
imx6q_imx_uart_data_entry(4,5),
};

4.clock.c
_REGISTER_CLOCK("imx_uart.0", NULL, uart_clk[0]),
_REGISTER_CLOCK("imx_uart.1", NULL, uart_clk[0]),
_REGISTER_CLOCK("imx_uart.2", NULL, uart_clk[0]),
_REGISTER_CLOCK("imx_uart.3", NULL, uart_clk[0]),
_REGISTER_CLOCK("imx_uart.4", NULL, uart_clk[0]),
