This commit configures all PWM function -pins to input GPIO mode. This will allow fans to run at full speed when BMC resets or in U-boot. - -Signed-off-by: Chanh Nguyen <chnguyen@amperecomputing.com> ---- - arch/arm/include/asm/arch-aspeed/ast_scu.h | 1 + - arch/arm/mach-aspeed/ast-scu.c | 12 ++++++++++++ - board/aspeed/ast-g5/ast-g5.c | 10 ++++++++++ - include/configs/ast-g5-phy.h | 3 +++ - 4 files changed, 26 insertions(+) - -diff --git a/arch/arm/include/asm/arch-aspeed/ast_scu.h b/arch/arm/include/asm/arch-aspeed/ast_scu.h -index dcbc6730d4..d2c010a0dc 100644 ---- a/arch/arm/include/asm/arch-aspeed/ast_scu.h -+++ b/arch/arm/include/asm/arch-aspeed/ast_scu.h -@@ -45,5 +45,6 @@ extern u32 ast_scu_get_vga_memsize(void); - extern void ast_scu_init_eth(u8 num); - extern void ast_scu_multi_func_eth(u8 num); - extern void ast_scu_multi_func_romcs(u8 num); -+extern void ast_scu_switch_pwm_to_gpio_mode(void); - - #endif -diff --git a/arch/arm/mach-aspeed/ast-scu.c b/arch/arm/mach-aspeed/ast-scu.c -index 12de9b8036..ef90ef3805 100644 ---- a/arch/arm/mach-aspeed/ast-scu.c -+++ b/arch/arm/mach-aspeed/ast-scu.c -@@ -443,6 +443,18 @@ void ast_scu_multi_func_eth(u8 num) - } - } - -+void ast_scu_switch_pwm_to_gpio_mode(void) -+{ -+ ast_scu_write(ast_scu_read(AST_SCU_FUN_PIN_CTRL3) & -+ ~SCU_FUN_PIN_VPIG2 & -+ ~SCU_FUN_PIN_VPIG3 & -+ ~SCU_FUN_PIN_VPIG4 & -+ ~SCU_FUN_PIN_VPIG5 & -+ ~SCU_FUN_PIN_VPIG6 & -+ ~SCU_FUN_PIN_VPIG7, -+ AST_SCU_FUN_PIN_CTRL3); -+} -+ - void ast_scu_multi_func_romcs(u8 num) - { - ast_scu_write(ast_scu_read(AST_SCU_FUN_PIN_CTRL3) | -diff --git a/board/aspeed/ast-g5/ast-g5.c b/board/aspeed/ast-g5/ast-g5.c -index e67a4bf8b2..fba22a728e 100644 ---- a/board/aspeed/ast-g5/ast-g5.c -+++ b/board/aspeed/ast-g5/ast-g5.c -@@ -24,6 +24,16 @@ int board_init(void) - return 0; - } - -+#ifdef CONFIG_BOARD_LATE_INIT -+int board_late_init(void) -+{ -+ /* Switch PWM to GPIO mode to make FAN run in max speed */ -+ ast_scu_switch_pwm_to_gpio_mode(); -+ -+ return 0; -+} -+#endif -+ - int dram_init(void) - { - u32 vga = ast_scu_get_vga_memsize(); -diff --git a/include/configs/ast-g5-phy.h b/include/configs/ast-g5-phy.h -index 62ddb841e5..5443a26cab 100644 ---- a/include/configs/ast-g5-phy.h -+++ b/include/configs/ast-g5-phy.h -@@ -30,4 +30,7 @@ - /* platform.S */ - #define CONFIG_DRAM_ECC_SIZE 0x10000000 - -+/* Call board_late_init */ -+#define CONFIG_BOARD_LATE_INIT 1 -+ - #endif /* __AST_G5_PHY_CONFIG_H */ --- -2.25.1 - |
