It's not used there either, but I didn't want to lose it. No functional changes. Tested on DB1300 and DB1500. --- arch/mips/alchemy/board-mtx1.c | 4 +- arch/mips/alchemy/board-xxs1500.c | 4 +- arch/mips/alchemy/common/clocks.c | 7 +- arch/mips/alchemy/common/dbdma.c | 22 +- arch/mips/alchemy/common/dma.c | 15 +- arch/mips/alchemy/common/irq.c | 4 +- arch/mips/alchemy/common/platform.c | 2 +- arch/mips/alchemy/common/power.c | 88 +- arch/mips/alchemy/common/setup.c | 3 +- arch/mips/alchemy/common/time.c | 25 +- arch/mips/alchemy/devboards/db1000.c | 5 +- arch/mips/alchemy/devboards/db1200.c | 29 +- arch/mips/alchemy/devboards/db1300.c | 10 +- arch/mips/alchemy/devboards/db1550.c | 25 +- arch/mips/alchemy/devboards/pm.c | 39 +- arch/mips/include/asm/mach-au1x00/au1000.h | 2571 ++++++++++------------- arch/mips/include/asm/mach-au1x00/au1000_dma.h | 51 +- arch/mips/include/asm/mach-au1x00/gpio-au1000.h | 66 +- arch/mips/pci/pci-alchemy.c | 65 +- drivers/mmc/host/au1xmmc.c | 168 +- drivers/mtd/nand/au1550nd.c | 52 +- drivers/net/ethernet/amd/au1000_eth.c | 155 +- drivers/rtc/rtc-au1xxx.c | 18 +- drivers/spi/spi-au1550.c | 66 +- drivers/video/fbdev/au1100fb.c | 15 +- drivers/video/fbdev/au1200fb.c | 34 +- sound/soc/au1x/psc-ac97.c | 140 +- sound/soc/au1x/psc-i2s.c | 100 +- sound/soc/au1x/psc.h | 22 +- 29 files changed, 1826 insertions(+), 1979 deletions(-) diff --git a/arch/mips/alchemy/board-mtx1.c b/arch/mips/alchemy/board-mtx1.c index 25a59a2..962cefa 100644 --- a/arch/mips/alchemy/board-mtx1.c +++ b/arch/mips/alchemy/board-mtx1.c @@ -85,10 +85,10 @@ void __init board_setup(void) #endif /* IS_ENABLED(CONFIG_USB_OHCI_HCD) */ /* Initialize sys_pinfunc */ - au_writel(SYS_PF_NI2, SYS_PINFUNC);
