PM / devfreq: exynos: Rename Exynos to lowercase

2020-01-06T01:50:09+00:00

Fix up inconsistent usage of upper and lowercase letters in "Exynos"
name.

"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

PM / devfreq: exynos-nocp: Fix module autoload

2016-11-17T02:31:27+00:00

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/devfreq/event/exynos-nocp.ko | grep alias
$

After this patch:

$ modinfo drivers/devfreq/event/exynos-nocp.ko | grep alias
alias:          of:N*T*Csamsung,exynos5420-nocpC*
alias:          of:N*T*Csamsung,exynos5420-nocp

PM / devfreq: exynos-nocp: Remove incorrect IS_ERR() check

2016-06-22T04:52:55+00:00

Smatch complains because platform_get_resource() returns NULL on error
and not an error pointer so the check is wrong.  Julia Lawall pointed
out that normally we don't check these, because devm_ioremap_resource()
has a check for NULL.

PM / devfreq: event: Add new Exynos NoC probe driver

2016-05-03T02:21:07+00:00

This patch adds NoC (Network on Chip) Probe driver which provides
the primitive values to get the performance data. The packets that the Network
on Chip (NoC) probes detects are transported over the network infrastructure.
Exynos542x bus has multiple NoC probes to provide bandwidth information about
behavior of the SoC that you can use while analyzing system performance.
