sh: prefer _THIS_IP_ to current_text_addr

2018-08-17T23:20:27+00:00

As part of the effort to reduce the code duplication between _THIS_IP_
and current_text_addr(), let's consolidate callers of
current_text_addr() to use _THIS_IP_.

Merge tag 'dma-mapping-4.19' of git://git.infradead.org/users/hch/dma-mapping

2018-08-14T18:11:52+00:00

Pull dma-mapping updates from Christoph Hellwig:

 - a series from Robin to fix bus imposed dma limits by adding a
   separate mask for them to struct device instead of trying to squeeze
   a second meaning out of the existing dma mask as we did before.

   This has ACKs from the various other subsystems touched

 - a small swiotlb cleanup from Kees (acked by Konrad)

 - conversion of nios2 and sh to the new generic dma-noncoherent code.

   Various other architecture conversions will come through the
   architectures maintainers trees.

sh: split arch/sh/mm/consistent.c

2018-08-02T11:54:15+00:00

Half of the file just contains platform device memory setup code which
is required for all builds, and half contains helpers for dma coherent
allocation, which is only needed if CONFIG_DMA_NONCOHERENT is enabled.

sh: use dma_direct_ops for the CONFIG_DMA_COHERENT case

2018-08-02T11:54:11+00:00

This is a slight change in behavior as we avoid the detour through the
virtual mapping for the coherent allocator, but if this CPU really is
coherent that should be the right thing to do.

media: arch: sh: ap325rxa: Use new renesas-ceu camera driver

2018-06-28T11:29:00+00:00

Use the new renesas-ceu camera driver in ap325rxa board file instead of
the soc_camera based sh_mobile_ceu_camera driver.

Get rid of soc_camera specific components, and register CEU0 with a single
video sensor (ov7725).

Memory for the CEU video buffers is now reserved with membocks APIs
and need to be declared as dma_coherent during machine initialization to
remove that architecture specific part from CEU driver.

The ap325rxa board file registers another camera (ncm03j) for which I found no
driver in mainline kernel version, and that was configured/probed by sending
i2c messages (of 'magic blobs) from the board file itself. I removed the
sensor registration from this new version as it used soc_camera components
that will be later removed.

While at there update license to SPDX header and sort headers alphabetically.

Compile tested only.

This field seem to be unused, perhaps a leftover from old code...
