memory: ti-emif: simplify platform_get_resource()

2022-04-26T07:48:25+00:00

Use devm_platform_ioremap_resource() instead of platform_get_resource()
and devm_ioremap_resource().

memory: ti-aemif: Drop child node when jumping out loop

2021-01-25T19:18:42+00:00

Call of_node_put() to decrement the reference count of the child node
child_np when jumping out of the loop body of
for_each_available_child_of_node(), which is a macro that increments and
decrements the reference count of child node. If the loop is broken, the
reference of the child node should be dropped manually.

memory: ti-aemif: fix a potential NULL-pointer dereference

2018-09-06T17:04:07+00:00

Platform data pointer may be NULL. We check it everywhere but in one
place. Fix it.

memory: aemif: add support for board files

2018-04-20T17:14:27+00:00

Currently aemif is supported in two places separately. By the platform
driver in drivers/memory and by a hand crafted driver in mach-davinci.

We want to drop the latter but also keep the legacy mode. Add support
for board files to the aemif driver.

The new structure in platform data currently only contains the chip
select number, since currently existing users don't require anything
else, but it can be extended in the future.

While extending the platform data struct, add kernel docs describing
its members.

We want to use aemif from board files. Use a static name in the

memory: aemif: allow passing device lookup table as platform data

2017-01-19T11:42:25+00:00

TI aemif driver creates its own subnodes of the device tree in order
to guarantee that all child devices are probed after the AEMIF timing
parameters are configured.

Some devices (e.g. da850) use struct of_dev_auxdata for clock lookup
but nodes created from within the aemif driver can't access the lookup
table.

Create a platform data structure that holds a pointer to
of_dev_auxdata so that we can use it with of_platform_populate().
