{
am33xx_cpuidle_init();
am33xx_mux_init(board_mux);
omap_serial_init();
omap_sdrc_init(NULL, NULL);
omap_board_config = am335x_evm_config;
omap_board_config_size = ARRAY_SIZE(am335x_evm_config);
/* Create an alias for icss clock */
if (clk_add_alias("pruss", NULL, "pruss_uart_gclk", NULL))
pr_warn("failed to create an alias: icss_uart_gclk --> pruss\n");
/* Create an alias for gfx/sgx clock */
if (clk_add_alias("sgx_ck", NULL, "gfx_fclk", NULL))
pr_warn("failed to create an alias: gfx_fclk --> sgx_ck\n");
}
How can I fix this problem?
