Fix this by moving all cache-related forward declarations to

sh: check return code of request_irq

2021-09-17T17:59:59+00:00

request_irq is marked __must_check, but the call in shx3_prepare_cpus
has a void return type, so it can't propagate failure to the caller.
Follow cues from hexagon and just print an error.

tmu3_device platform device to new style of platform data but removed it
from sh7786_early_devices array effectively removing last three timers

sh: add the sh_ prefix to early platform symbols

2019-10-07T11:50:48+00:00

Old early platform device support is now sh-specific. Before moving on
to implementing new early platform framework based on real platform
devices, prefix all early platform symbols with 'sh_'.

drivers: move the early platform device support to arch/sh

2019-10-07T11:50:47+00:00

SuperH is the only user of the current implementation of early platform
device support. We want to introduce a more robust approach to early
probing. As the first step - move all the current early platform code
to arch/sh.

In order not to export internal drivers/base functions to arch code for
this temporary solution - copy the two needed routines for driver
matching from drivers/base/platform.c to arch/sh/drivers/platform_early.c.

Also: call early_platform_cleanup() from subsys_initcall() so that it's
called after all early devices are probed.

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.

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

2018-03-21T19:29:59+00:00

SH4 7724 Ecovec platform uses sh_mobile_ceu camera driver, which is now
being replaced by a proper V4L2 camera driver named 'renesas-ceu'.

Get rid of soc_camera defined components used to register sensor drivers
and of platform specific enable/disable routines.

Register GPIOs for sensor drivers and declare memory reserved with
memblock APIs as dma capable to be used for CEU buffers.

While at there re-order include directives to respect alphabetical
ordering.
