soc/tegra: pmc: Use existing pclk reference

2015-08-13T14:49:58Z

The driver requests the pclk clock at probe time already and stores its reference to it in struct tegra_pmc, so there is no need to look it up everytime it is needed. Use the existing reference instead. Signed-off-by: Thierry Reding

soc/tegra: pmc: Remove unnecessary return statement

2015-08-13T14:49:43Z

Functions returning no value don't need an explicit return statement. Signed-off-by: Thierry Reding

soc/tegra: pmc: Add Tegra210 support

2015-07-16T08:38:27Z

Tegra210 uses a power management controller that is compatible with earlier SoC generations but adds a couple of power partitions for new hardware blocks. Reviewed-by: Paul Walmsley Signed-off-by: Thierry Reding

soc/tegra: pmc: Restrict legacy code to 32-bit ARM

2015-07-16T08:38:26Z

For backwards-compatibility with old device trees, if no PMC node exists this driver hard-codes the I/O memory region. All 64-bit ARM device tree files are recent enough that they can be required to have this node, and therefore the legacy code path is not required on 64-bit ARM. Based on work done by Paul Walmsley .

soc/tegra: pmc: Avoid usage of uninitialized variable

2015-07-16T08:38:20Z

Make sure to only drop the reference to the OF node after it's been successfully obtained. Fixes: 3568df3d31d6 ("soc: tegra: Add thermal reset (thermtrip) support to PMC") Cc: # v4.0+ Reviewed-by: Mikko Perttunen Signed-off-by: Thierry Reding

Pull module_platform_driver replacement from Paul Gortmaker: "Replace module_platform_driver with builtin_platform driver in non modules. We see an increasing number of non-modular drivers using modular_driver() type register functions. There are several downsides to letting this continue unchecked: - The code can appear modular to a reader of the code, and they won't know if the code really is modular without checking the Makefile and Kconfig to see if compilation is governed by a bool or tristate. - Coders of drivers may be tempted to code up an __exit function that is never used, just in order to satisfy the required three args of the modular registration function. - Non-modular code ends up including the which increases CPP overhead that they don't need. - It hinders us from performing better separation of the module init code and the generic init code. So here we introduce similar macros for builtin drivers. Then we convert builtin drivers (controlled by a bool Kconfig) by making the following type of mapping: module_platform_driver() ---> builtin_platform_driver() module_platform_driver_probe() ---> builtin_platform_driver_probe(). The set of drivers that are converted here are just the ones that showed up as relying on an implicit include of during a pending header cleanup. So we convert them here vs adding an include of to non-modular code to avoid compile fails. Additonal conversions can be done asynchronously at any time. Once again, an unused module_exit function that is removed here appears in the diffstat as an outlier wrt all the other changes" * tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: drivers/clk: convert sunxi/clk-mod0.c to use builtin_platform_driver drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver drivers/cpufreq: Convert non-modular s5pv210-cpufreq.c to use builtin_platform_driver drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driver drivers/platform: Convert non-modular pdev_bus to use builtin_platform_driver platform_device: better support builtin boilerplate avoidance

drivers/soc: Convert non-modular tegra/pmc to use builtin_platform_driver

2015-06-16T18:12:38Z

This file depends on Kconfig ARCH_TEGRA which is a bool, so we use the appropriate registration function, which avoids us relying on an implicit inclusion of which we are doing currently. While this currently works, we really don't want to be including the module.h header in non-modular code, which we'd be forced to do, pending some upcoming code relocation from init.h into module.h. So we fix it now by using the non-modular equivalent. Cc: Stephen Warren Cc: Thierry Reding Cc: Alexandre Courbot Cc: linux-tegra@vger.kernel.org Signed-off-by: Paul Gortmaker

soc/tegra: pmc: move to using a restart handler

2015-05-04T12:21:45Z

The pmc driver was previously exporting tegra_pmc_restart, which was assigned to machine_desc.init_machine, taking precedence over the restart handlers registered through register_restart_handler().

soc: tegra: Add thermal reset (thermtrip) support to PMC

2015-01-23T15:20:49Z

This adds a device tree controlled option to enable PMC-based thermal reset in overheating situations. Thermtrip is supported on Tegra30, Tegra114 and Tegra124. The thermal reset only works when the thermal sensors are calibrated, so a soctherm driver is also required. The thermtrip event is triggered by the soctherm block, and all soctherm sensors default to showing a temperature of zero Celsius before they are initialized. Because of this, it is safe to initialize thermtrip and soctherm in any order. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

soc/tegra: pmc: Add Tegra132 support

2015-01-09T15:14:53Z

Tegra132 uses the same GPU as Tegra124 and therefore requires the same method to remove clamps. However Tegra132 has a separate chip ID, so in order to avoid having to extend the list of chip IDs for the special case, add a feature flag to the SoC data.
