soc/tegra: Move Tegra flowctrl driver

2017-04-04T13:48:04+00:00

The flowctrl driver is required for both ARM and ARM64 Tegra devices and in order to enable support for it for ARM64, move the Tegra flowctrl driver into drivers/soc/tegra. By moving the flowctrl driver, tegra_flowctrl_init() is now called by via an early initcall and to prevent this function from attempting to mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()' is also added.

ARM: tegra: Initialize flow controller from DT

2014-08-26T17:43:55+00:00

Use a matching device tree node to initialize the flow controller driver instead of hard-coding the I/O address. This is necessary to get rid of the iomap.h include, which in turn make it easier to share this code with 64-bit Tegra SoCs. Signed-off-by: Thierry Reding Signed-off-by: Stephen Warren

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

2014-07-17T11:36:41+00:00

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

2014-07-17T11:29:57+00:00

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: add LP1 support code for Tegra124

2013-10-18T22:28:10+00:00

The LP1 suspend procedure is the same with Tegra30 and Tegra114. Just need to update the difference of the register address, then we can continue to share the code. Signed-off-by: Joseph Lo Signed-off-by: Stephen Warren

ARM: tegra: flowctrl: add support for cpu_suspend_enter/exit

2013-07-19T16:08:08+00:00

The flow controller can help CPU to go into suspend mode (powered-down state). When CPU goes into powered-down state, it needs some careful settings before getting into and after leaving. The enter and exit functions do that by configuring appropriate mode for flow controller. For Tegra114, the setting is compatible with Tegra30. Signed-off-by: Joseph Lo Signed-off-by: Stephen Warren

ARM: tegra: move iomap.h to mach-tegra

2012-11-05T18:36:06+00:00

Nothing outside mach-tegra uses this file, so there's no need for it to be in . Since uncompress.h and debug-macro.S remain in include/mach, they need to include "../../iomap.h" becaue of this change. uncompress.h will soon be deleted in later multi-platform/single-zImage patches. debug-macro.S will need to continue to include this header using an explicit relative path, to avoid duplicating the physical->virtual address mapping that iomap.h dictates.
