I am trying to boot the Renesas R-Car H1 (Marzen) board with 3.10 LTSi kernel which is present at : https://git.kernel.org/cgit/linux/kernel/git/horms/renesas-backport.git/ Branch: backport/v3.10.28-ltsi-rc1/snapshot There are no sound cards detected on booting this kernel, although graphics is found to be working. Are there any updates which adds the RCAR_SOUND support to Marzen on v3.10 LTSi kernel ? -------------------------- root at marzenh1:~# cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 29: 5840 17228 5026 14491 GIC twd 59: 0 0 0 0 GIC renesas_intc_irqpin 60: 8094 0 0 0 GIC renesas_intc_irqpin 61: 0 0 0 0 GIC renesas_intc_irqpin 62: 0 0 0 0 GIC renesas_intc_irqpin 63: 0 0 0 0 GIC rcar-du-r8a7779, rcar-du-r8a7779 64: 13 0 0 0 GIC sh_tmu.0 76: 60 0 0 0 GIC ehci_hcd:usb1, ohci_hcd:usb3 77: 1 0 0 0 GIC ehci_hcd:usb2, ohci_hcd:usb4 96: 0 0 0 0 GIC r8a7779-vin.1 98: 0 0 0 0 GIC r8a7779-vin.3 111: 82 0 0 0 GIC i2c-rcar.0 112: 0 0 0 0 GIC i2c-rcar.2 113: 0 0 0 0 GIC i2c-rcar.3 114: 0 0 0 0 GIC i2c-rcar.1 122: 982 0 0 0 GIC sh-sci.2:mux 132: 0 0 0 0 GIC sata_rcar 136: 52 0 0 0 GIC sh_mobile_sdhi.0 173: 0 0 0 0 GIC gpio_rcar.0 174: 0 0 0 0 GIC gpio_rcar.1 175: 0 0 0 0 GIC gpio_rcar.2 176: 0 0 0 0 GIC gpio_rcar.3 177: 0 0 0 0 GIC gpio_rcar.4 178: 0 0 0 0 GIC gpio_rcar.5 179: 0 0 0 0 GIC gpio_rcar.6 2001: 8094 0 0 0 renesas_intc_irqpin eth0 IPI0: 0 0 0 0 CPU wakeup interrupts IPI1: 0 0 0 0 Timer broadcast interrupts IPI2: 476 1715 1732 1236 Rescheduling interrupts IPI3: 50 62 112 112 Function call interrupts IPI4: 0 0 0 0 Single function call interrupts IPI5: 0 0 0 0 CPU stop interrupts Err: 0 ... .... ..... root at marzenh1:~# aplay -l aplay: device_list:268: no soundcards found... --------------------------- When will be the Audio support available for R-Car Marzen (R8A7779) on v3.10 LTSi kernel ?
