sh: superhyway: use dev_groups and not dev_attrs for bus_type

2017-06-09T09:00:46+00:00

The dev_attrs field has long been "depreciated" and is finally being
removed, so move the driver to use the "correct" dev_groups field
instead for struct bus_type.

lib: radix-tree: check accounting of existing slot replacement users

2016-12-13T02:55:08+00:00

The bug in khugepaged fixed earlier in this series shows that radix tree
slot replacement is fragile; and it will become more so when not only
NULL<->!NULL transitions need to be caught but transitions from and to
exceptional entries as well.  We need checks.

Re-implement radix_tree_replace_slot() on top of the sanity-checked
__radix_tree_replace().  This requires existing callers to also pass the
radix tree root, but it'll warn us when somebody replaces slots with
contents that need proper accounting (transitions between NULL entries,
real entries, exceptional entries) and where a replacement through the
slot pointer would corrupt the radix tree node counts.

drivers: sh: Stop using the legacy clock domain on ARM

2016-05-30T00:41:11+00:00

Since commits 71d076ceb245f0d9 ("ARM: shmobile: Enable PM and
PM_GENERIC_DOMAINS for SoCs with PM Domains") and 2ee98234b88174f2
("arm64: renesas: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM
Domains"), CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled
unconditionally for Renesas ARM-based SoCs. Hence the legacy clock
domain is no longer used on these SoCs.

Remove the related support code, and stop entering drivers/sh/ on ARM.

drivers: sh: Restore legacy clock domain on SuperH platforms

2016-02-25T00:05:19+00:00

CONFIG_ARCH_SHMOBILE is not only enabled for Renesas ARM platforms
(which are DT based and multi-platform), but also on a select set of
Renesas SuperH platforms (SH7722/SH7723/SH7724/SH7343/SH7366). Hence
since commit 0ba58de231066e47 ("drivers: sh: Get rid of
CONFIG_ARCH_SHMOBILE_MULTI"), the legacy clock domain is no longer
installed on these SuperH platforms, and module clocks may not be
enabled when needed, leading to driver failures.

To fix this, add an additional check for CONFIG_OF.

Fixes: 0ba58de231066e47 ("drivers: sh: Get rid of CONFIG_ARCH_SHMOBILE_MULTI").

drivers: Initialize resource entry to zero

2016-01-30T08:49:58+00:00

I/O resource descriptor, 'desc' in struct resource, needs to be
initialized to zero by default.  Some drivers call kmalloc() to
allocate a resource entry, but do not initialize it to zero by
memset().  Change these drivers to call kzalloc(), instead.

drivers: sh: clk: Avoid crashes when passing NULL clocks

2015-11-24T02:49:18+00:00

Several clock API functions handle NULL clocks when the Common Clock
Framework is used, while their legacy SH counterparts don't, and would
just crash when a NULL clock is passed.

Add NULL checks to clk_get_rate(), clk_set_rate(), clk_get_parent(), and
clk_round_rate(), to avoid different behavior in drivers shared between
legacy and CCF-based platforms.

drivers: sh: clk: Remove obsolete and unused clk_round_parent()

2015-11-24T02:48:35+00:00

clk_round_parent() was only ever used by AP4EVB, until commit
b24bd7e97b3784af ("ARM: shmobile: Remove AP4EVB board support").

The Common Clock Framework does not provide clk_round_parent(), hence
remove it.
