	Based on 1 normalized pattern(s): this program is free software you can redistribute it and or modify it under the terms and conditions of the gnu general public license version 2 as published by the free software foundation this program is distributed in the hope it will be useful but without any warranty without even the implied warranty of merchantability or fitness for a particular purpose see the gnu general public license for more details you should have received a copy of the gnu general public license along with this program if not see http www gnu org licenses extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 228 file(s).

2014-07-17	ARM: tegra: Sort includes alphabetically	Thierry Reding	1	-0/+1
	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 <treding@nvidia.com>
2013-08-12	ARM: tegra: add LP1 suspend support for Tegra30	Joseph Lo	1	-0/+34
	The LP1 suspend mode will power off the CPU, clock gated the PLLs and put SDRAM to self-refresh mode. Any interrupt can wake up device from LP1. The sequence when LP1 suspending: * tunning off L1 data cache and the MMU * storing some EMC registers, DPD (deep power down) status, clk source of mselect and SCLK burst policy * putting SDRAM into self-refresh * switching CPU to CLK_M (12MHz OSC) * tunning off PLLM, PLLP, PLLA, PLLC and PLLX * switching SCLK to CLK_S (32KHz OSC) * shutting off the CPU rail The sequence of LP1 resuming: * re-enabling PLLM, PLLP, PLLA, PLLC and PLLX * restoring the clk source of mselect and SCLK burst policy * setting up CCLK burst policy to PLLX * restoring DPD status and some EMC registers * resuming SDRAM to normal mode * jumping to the "tegra_resume" from PMC_SCRATCH41 Due to the SDRAM will be put into self-refresh mode, the low level procedures of LP1 suspending and resuming should be copied to TEGRA_IRAM_CODE_AREA (TEGRA_IRAM_BASE + SZ_4K) when suspending. Before restoring the CPU context when resuming, the SDRAM needs to be switched back to normal mode. And the PLLs need to be re-enabled, SCLK burst policy be restored, CCLK burst policy be set in PLLX. Then jumping to "tegra_resume" that was expected to be stored in PMC_SCRATCH41 to restore CPU context and back to kernel.
