kernel/drivers/clocksource/sh_cmt.c, branch linux-4.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-4.1.y2015-03-13T07:07:08Zclocksource: Rename __clocksource_updatefreq_*() to __clocksource_update_freq_*()2015-03-13T07:07:08ZJohn Stultzjohn.stultz@linaro.org2015-03-12T04:16:40Zurn:sha1:fba9e07208c0f9d92d9f73761c99c8612039da44
Ingo requested this function be renamed to improve readability,
so I've renamed __clocksource_updatefreq_scale() as well as the
__clocksource_updatefreq_hz/khz() functions to avoid
squishedtogethernames.
This touches some of the sh clocksources, which I've not tested.
The arch/arm/plat-omap change is just a comment change for
consistency.

clocksource: sh_cmt: Replace global spinlock with a per-device spinlock2014-07-02T14:01:48ZLaurent Pinchartlaurent.pinchart+renesas@ideasonboard.com2014-02-17T15:49:05Zurn:sha1:de599c8843ebbdfc29a119c94af481b1de76700e
The global spinlock is used to protect the shared start/stop register.
Now that all CMT channels are handled by a single device instance, use a
per-device spinlock.

duplicate the MM subsystem generic OOM message.

Clock sources don't need an IRQ, request the IRQ only for channels used
as clock event devices.

Do not include the paragraph about writing to the Free Software

changed addresses in the past, and may do so again. Linux already
includes a copy of the GPL.

clocksource: sh_cmt: Rename clock to "fck" in the non-legacy case2014-04-16T10:03:14ZLaurent Pinchartlaurent.pinchart+renesas@ideasonboard.com2014-02-13T23:35:18Zurn:sha1:24b4e07df54b7bf7739fb3dd193f639a8f274ad6
The sh_cmt driver gets the CMT functional clock using a connection ID of
"cmt_fck". While all SH SoCs create clock lookup entries with a NULL
device ID and a "cmt_fck" connection ID, the ARM SoCs use the device ID
only with a NULL connection ID. This works on legacy platforms but will
break on ARM with DT boot.
Fix the situation by using a connection ID of "fck" in the non-legacy
platform data case. Clock lookup entries will be renamed to use the
device ID as well as the connection ID as platforms get moved to new
platform data. The legacy code will eventually be dropped, leaving us
with device ID based clock lookup, compatible with DT boot.

clocksource: sh_cmt: Add support for multiple channels per device2014-04-16T10:03:14ZLaurent Pinchartlaurent.pinchart+renesas@ideasonboard.com2014-01-28T11:36:48Zurn:sha1:81b3b2711072b6047d5f332cd8751a1c5c9a3fb2
CMT hardware devices can support multiple channels, with global
registers and per-channel registers. The sh_cmt driver currently models
the hardware with one Linux device per channel. This model makes it
difficult to handle global registers in a clean way.
Add support for a new model that uses one Linux device per timer with
multiple channels per device. This requires changes to platform data,
add new channel configuration fields.
Support for the legacy model is kept and will be removed after all
platforms switch to the new model.
