ARM: tegra: hotplug: Include missing common.h

2016-06-10T14:17:58Z

Some of the functions implemented are flagged as not having a prototype defined when building with W=1. Include the header to avoid these build warnings. Signed-off-by: Thierry Reding

ARM: Remove __ref on hotplug cpu die path

2015-10-22T16:55:03Z

Now that __cpuinit has been removed, the __ref markings on these functions are useless. Remove them. This also reduces the size of the multi_v7_defconfig image: $ size before after text data bss dec hex filename 12683578 1470996 348904 14503478 dd4e36 before 12683274 1470996 348904 14503174 dd4d06 after presumably because now we don't have to jump to code in the .ref.text section and/or the noinline marking is removed.

ARM: tegra: Setup CPU hotplug in a pure initcall

2014-07-17T12:58:41Z

CPU hotplug support doesn't have to be set up until fairly late in the boot process, so it can be done in a regular initcall. To make sure that we don't miss any ordering problems in the future, output a warning if any of the functions are called before initialization has completed. This is part of untangling the boot order dependencies on Tegra so that more code can be shared between 32-bit and 64-bit ARM. Signed-off-by: Thierry Reding

ARM: tegra: Use a function to get the chip ID

2014-07-17T11:36:41Z

Instead of using a simple variable access to get at the Tegra chip ID, use a function so that we can run additional code. This can be used to determine where the chip ID is being accessed without being available. That in turn will be handy for resolving boot sequence dependencies in order to convert more code to regular initcalls rather than a sequence fixed by Tegra SoC setup code.

ARM: tegra: Sort includes alphabetically

2014-07-17T11:29:57Z

If these aren't sorted alphabetically, then the logical choice is to append new ones, however that creates a lot of potential for conflicts because every change will then add new includes in the same location. Signed-off-by: Thierry Reding

ARM: tegra: CPU hotplug support for Tegra124

2013-10-18T22:28:08Z

The procedure of CPU hotplug for Tegra124 is same with Tegra114. We re-use the same function with it. Signed-off-by: Joseph Lo Signed-off-by: Stephen Warren

ARM: tegra: add a flag for tegra_disable_clean_inv_dcache to do LoUIS or ALL

2013-07-19T16:08:05Z

Adding a flag for tegra_disable_clean_inv_dcache to flush cache as LoUIS or ALL. After this patch, the v7_flush_dcache_louis is used for CPU hotplug and CPU suspend in CPU power down (e.g. CPU idle power-down mode) case. And the v7_flush_dcache_all is used for CPU cluster power down (e.g. suspend to LP2 mode). Signed-off-by: Joseph Lo Signed-off-by: Stephen Warren

Revert "ARM: tegra: add cpu_disable for hotplug"

2013-07-19T16:00:37Z

This reverts commit 510bb59 "ARM: tegra: add cpu_disable for hotplug". The Tegra114 support CPU0 hotplug function in HW physically, but it needs other software to make it work normally after we add CPU idle power down mode support. So remove them for now.

ARM: tegra: add cpu_disable for hotplug

2013-05-28T21:26:07Z

The Tegra114 could hotplug the CPU0, but the common cpu_disable didn't support that. Adding a Tegra specific cpu_disable function for it. Signed-off-by: Joseph Lo [swarren: adjusted the switch statement to be future-proof] Signed-off-by: Stephen Warren
