These become a maintenance burden now, so our development group decided to remove upstream support and disable booting for this SoC. Public users only have ES2 onwards. Reviewed-by: Laurent Pinchart Reviewed-by: Geert Uytterhoeven Signed-off-by: Wolfram Sang --- Please apply individually per subsystem. There are no dependencies and the SoC doesn't boot anymore since v6.3-rc1. drivers/usb/host/xhci-rcar.c | 31 ++----------------------------- 1 file changed, 2 insertions(+), 29 deletions(-) diff --git a/drivers/usb/host/xhci-rcar.c b/drivers/usb/host/xhci-rcar.c index 567b096a24e9..c4925f8d6b06 100644 --- a/drivers/usb/host/xhci-rcar.c +++ b/drivers/usb/host/xhci-rcar.c @@ -12,26 +12,22 @@ #include #include #include -#include #include "xhci.h" #include "xhci-plat.h" #include "xhci-rzv2m.h" #define XHCI_RCAR_FIRMWARE_NAME_V1 "r8a779x_usb3_v1.dlmem" -#define XHCI_RCAR_FIRMWARE_NAME_V2 "r8a779x_usb3_v2.dlmem" #define XHCI_RCAR_FIRMWARE_NAME_V3 "r8a779x_usb3_v3.dlmem" /* -* - The V3 firmware is for almost all R-Car Gen3 (except r8a7795 ES1.x) -* - The V2 firmware is for r8a7795 ES1.x. +* - The V3 firmware is for all R-Car Gen3 * - The V2 firmware is possible to use on R-Car Gen2.
