PM / devfreq: tegra: remove unneeded variable

2019-04-16T00:29:18Z

This variable is not used after initialization, so remove it. And in order to unify the code style, move the location where the dev_get_drvdata is called by the way. Signed-off-by: Yangtao Li Reviewed-by: Chanwoo Choi Acked-by: Jon Hunter Signed-off-by: MyungJoo Ham

headers: separate linux/mod_devicetable.h from linux/platform_device.h

2018-07-07T15:52:26Z

At over 4000 #includes, is the 9th most #included header file in the Linux kernel. It does not need , so drop that header and explicitly add to source files that need it. 4146 #include After this patch, there are 225 files that use , for a reduction of around 3900 times that does not have to be read & parsed. 225 #include This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

PM / devfreq: tegra: fix error return code in tegra_devfreq_probe()

2017-07-06T01:16:17Z

platform_get_irq() returns an error code, but the tegra-devfreq driver ignores it and always returns -ENODEV. This is not correct, and prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e330b9a6bb35dc7097a4f02cb1ae7b6f96df92af Print and propagate the return value of platform_get_irq on failure.

PM / OPP: Update OPP users to put reference

2017-01-30T08:22:21Z

This patch updates dev_pm_opp_find_freq_*() routines to get a reference to the OPPs returned by them. Also updates the users of dev_pm_opp_find_freq_*() routines to call dev_pm_opp_put() after they are done using the OPPs. As it is guaranteed the that OPPs wouldn't get freed while being used, the RCU read side locking present with the users isn't required anymore. Drop it as well. This patch also updates all users of devfreq_recommended_opp() which was returning an OPP received from the OPP core. Note that some of the OPP core routines have gained rcu_read_{lock|unlock}() calls, as those still use RCU specific APIs within them.

PM / devfreq: tegra: Set freq in rate callback

2016-02-23T05:27:42Z

As per the documentation of the devfreq_dev_profile.target callback, set the freq argument to the new frequency before returning. This caused endless messages like this after recent changes in the core: devfreq 6000c800.actmon: Couldn't update frequency transition information.
