2014-07-17ARM: tegra: Convert PMC to a driverThierry Reding
This commit converts the PMC support code to a platform driver. Because the boot process needs to call into this driver very early, also set up a minimal environment via an early initcall. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-09-17ARM: tegra: delete stale header contentStephen Warren
A few function prototypes were left in header files during code re- organization. Delete them. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-09-17ARM: tegra: remove common.cStephen Warren
common.c was create to contain code shared across the various Tegra board files. There is now only one board file, tegra.c. So, move the code there. One exception is the PMC reboot routine, which moves to pmc.c, and now takes advantage of the 'standard' tegra_pmc_readl/writel functions. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-08-13PCI: tegra: Move PCIe driver to drivers/pci/hostThierry Reding
Move the PCIe driver from arch/arm/mach-tegra into the drivers/pci/host directory. The motivation is to collect various host controller drivers in the same location in order to facilitate refactoring. The Tegra PCIe driver has been largely rewritten, both in order to turn it into a proper platform driver and to add MSI (based on code by Krishna Kishore <kthota@nvidia.com>) as well as device tree support.

2013-07-09reboot: arm: change reboot_mode to use enum reboot_modeRobin Holt
Preparing to move the parsing of reboot= to generic kernel code forces the change in reboot_mode handling to use the enum.

2013-03-29ARM: tegra: move <mach/powergate.h> to <linux/tegra-powergate.h>Stephen Warren
This is required so that code such as Tegra's PCIe and clock drivers can still access this header file once Tegra is converted to multiplatform, and <mach/> no longer exists. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-03-11ARM: tegra: Unify tegra{20,30,114}_init_early()Hiroshi Doyu
Refactored tegra{20,30,114}_init_early() so that we have the unified tegra_init_early(). Signed-off-by: Hiroshi Doyu <hdoyu@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
2013-02-09ARM: tegra: Fix build error w/ ARCH_TEGRA_114_SOC w/o ARCH_TEGRA_3x_SOCOlof Johansson
This patch fixes the build error when ARCH_TEGRA_114_SOC is enabled and ARCH_TEGRA_3x_SOC is disabled. This provides Tegra114 with its own tegra114_init_early() instead of making use of tegra30_init_early() so that T114 build doesn't depend on T3x anymore.

2013-01-28ARM: tegra: move timer.c to drivers/clocksource/Stephen Warren
Move arch/arm/mach-tegra/timer.c to drivers/clocksource/tegra20_timer.c so that the code is co-located with other clocksource drivers, and to reduce the size of the mach-tegra directory. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-06-20ARM: tegra: paz00: enable WiFi rfkill when booting from device treeStephen Warren
There currently aren't bindings for a WiFi rfkill button, and defining a good binding is non-trivial. Manually register this "device" when booting from device tree, in order to bring DT support to the same feature level as board files, which will in turn allow board files to be deprecated.

2012-06-20ARM: tegra: harmony: init regulators, PCIe when booting from DTStephen Warren
There currently aren't bindings for the Tegra PCIe controller. Work on this is in progress, but not yet complete. Manually initialize PCIe when booting from device tree, in order to bring DT support to the same feature level as board files, which will in turn allow board files to be deprecated. PCIe on Harmony requires various regulators to be registered and enabled before initializing the PCIe controller. Note that since the I2C controllers are instantiated from DT, we must use i2c_new_device() to register the PMU rather than i2c_register_board_info().

2011-12-19arm/tegra: Delete tegra_init_clock()Stephen Warren
tegra_init_clock() is written to call tegra2_init_clocks(), which only exists if Tegra20 support is enabled. This breaks the build of a Tegra30-only kernel. tegra_init_clock() isn't actually used any more; tegra20_init_early() calls tegra2_init_clocks() directly. So, just delete this function.

2011-12-17arm/tegra: implement support for tegra30Peter De Schrijver
Add support for tegra30 SoC. This includes a device tree compatible type for this SoC ("nvidia,tegra30") and adds L2 cache initialization for this new SoC. The clock framework is still missing, which prevents most drivers from working. The basic IRQs are the same, so remove the dependency on CONFIG_ARCH_TEGRA_2x_SOC.

2011-02-22ARM: tegra: Move tegra_common_init to tegra_init_earlyColin Cross
Move tegra_common_init to tegra_init_early, and set it as the init_early entry in the machine struct. Initializes the clocks earlier so that timers can enable their clocks. Also reorders the members in the Harmony and Trimslice boards' machine structs to match the order they are called in.
