When building with LPAE=y (64-bit dma_addr_t), the following warnings are seen:
drivers/gpu/host1x/hw/cdma_hw.c:57:3: warning: format '%x' expects
argument of type 'unsigned int', but argument 5 has type 'dma_addr_t'
drivers/gpu/host1x/hw/debug_hw.c:167:10: warning: format '%x' expects
argument of type 'unsigned int', but argument 3 has type 'dma_addr_t'
The agreed-to solution for this is upcast to u64 and using %llx.

gpu: host1x: Add syncpoint base support2013-10-31T08:55:48ZArto Merilainen2013-10-14T12:21:53Zurn:sha1:f5a954fed9b3eb04973ede72c50c66157fa9e15b
This patch adds support for hardware syncpoint bases. This creates
a simple mechanism to stall the command FIFO until an operation is
completed.

Tegra114 uses a slightly updated version of host1x with an additional
syncpoint.

This is slightly safer than adding -Idrivers/gpu/host1x to cflags-y.

Expose the buffer objects, syncpoint and channel functionality in the
public public header so that drivers can use them.

Most of the included files are either not required or already included
by some other header file.

This patch merges host1x_syncpt_cpu_incr to host1x_syncpt_incr() as
they are in practise doing the same thing. host1x_syncpt_incr() is
also modified to return error codes. User space interface is modified
accordingly to pass return values.

Add support for host1x debugging. Adds debugfs entries, and dumps
channel state to UART in case of stuck job.
