However, the touch screen driver is trying to send messages of size 5.... (AC: Set to 20 bytes having checked the max size allowed) Signed-off-by: Arjan van de Ven Signed-off-by: Alan Cox Signed-off-by: Matthew Garrett --- diff --git a/drivers/platform/x86/intel_scu_ipc.c b/drivers/platform/x86/intel_scu_ipc.c index 5258749138d6..1b0d0d54cb0f 100644 --- a/drivers/platform/x86/intel_scu_ipc.c +++ b/drivers/platform/x86/intel_scu_ipc.c @@ -58,8 +58,8 @@ #define IPC_BASE_ADDR 0xFF11C000 /* IPC1 base register address */ #define IPC_MAX_ADDR 0x100 /* Maximum IPC regisers */ -#define IPC_WWBUF_SIZE 16 /* IPC Write buffer Size */ -#define IPC_RWBUF_SIZE 16 /* IPC Read buffer Size */ +#define IPC_WWBUF_SIZE 20 /* IPC Write buffer Size */ +#define IPC_RWBUF_SIZE 20 /* IPC Read buffer Size */ #define IPC_I2C_BASE 0xFF12B000 /* I2C control register base address */ #define IPC_I2C_MAX_ADDR 0x10 /* Maximum I2C regisers */
