There is no need to duplicate what SPI core already does, i.e. mapping buffers for DMA capable transfers. Remove all related pices of code. Note, that code, besides its redundancy, was buggy: DMA address potentially can be 0, SPI slave device has nothing to do with DMA capable device properties and DMA mask in particular. Suggested-by:

First of all, fbtft in current state doesn't allow to override GPIOs to be optional, like "reset" one. It might be a bug somewhere, but rather out of scope of this fix. Second, not all GPIOs available on the board would be SoC based, some of them might sit on I2C GPIO expanders, for example, on Intel Edison/Arduino, and thus any communication with them might sleep. Besides that using udelay() and mdelay() is kinda resource wasteful. Summarize all of the above, convert fbtft_reset() function to non-atomic variant by using gpio_set_value_cansleep(), usleep_range(), and msleep(). Reviewed-by:

vfree frees the virtually continuous block of memory beginning at addr. If addr is NULL, no operation is performed. So, NULL test is not needed before vfree(). Signed-off-by:

The constants MAX_COMPLETIONS and MSG_QUEUE_SIZE control the number of messages that can be outstanding to each client before the system as a whole stalls. If the numbers are too small then unnecessary thread switching will occur while waiting for a (potentially low priority) client thread to consume some data; badly written clients can even lead to deadlock. For services that carry many short messages, 16 messages can represent a very small amount of data. Since the resources are small - 16 bytes for a completion, 4 bytes for a message pointer - increase the limits so they are unlikely to be hit except in exceptional circumstances. Signed-off-by:

An issue was observed when flushing openmax components which generate a large number of messages returning buffers to host. We occasionally found a duplicate message from 16 messages prior, resulting in a buffer returned twice. So fix the issue by adding more memory barriers. Signed-off-by:
