These devices should have a clkfreq nvram configuration value set - to 200, read it and set the clock to the correct value. - - Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> - Cc: linux-mips@linux-mips.org - Patchwork: https://patchwork.linux-mips.org/patch/5842/ - Signed-off-by: Ralf Baechle <ralf@linux-mips.org> - ---- a/arch/mips/bcm47xx/time.c -+++ b/arch/mips/bcm47xx/time.c -@@ -27,10 +27,14 @@ - #include <linux/ssb/ssb.h> - #include <asm/time.h> - #include <bcm47xx.h> -+#include <bcm47xx_nvram.h> - - void __init plat_time_init(void) - { - unsigned long hz = 0; -+ u16 chip_id = 0; -+ char buf[10]; -+ int len; - - /* - * Use deterministic values for initial counter interrupt -@@ -43,15 +47,23 @@ void __init plat_time_init(void) - #ifdef CONFIG_BCM47XX_SSB - case BCM47XX_BUS_TYPE_SSB: - hz = ssb_cpu_clock(&bcm47xx_bus.ssb.mipscore) / 2; -+ chip_id = bcm47xx_bus.ssb.chip_id; - break; - #endif - #ifdef CONFIG_BCM47XX_BCMA - case BCM47XX_BUS_TYPE_BCMA: - hz = bcma_cpu_clock(&bcm47xx_bus.bcma.bus.drv_mips) / 2; -+ chip_id = bcm47xx_bus.bcma.bus.chipinfo.id; - break; - #endif - } - -+ if (chip_id == 0x5354) { -+ len = bcm47xx_nvram_getenv("clkfreq", buf, sizeof(buf)); -+ if (len >= 0 && !strncmp(buf, "200", 4)) -+ hz = 100000000; -+ } -+ - if (!hz) - hz = 100000000; - |
