ARM: tegra: remove common.c

2013-09-17T19:44:21+00:00

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

ARM: tegra: split tegra_pmc_init() in two

2013-09-17T19:42:17+00:00

Tegra's board file currently initializes clocks much earlier than those for most other ARM SoCs. The reason is: * The PMC HW block is involved in the path of some interrupts (i.e. it inverts, or not, the IRQ input pin dedicated to the PMIC). * So, that part of the PMC must be initialized early so that the IRQ polarity is correct. * The PMC initialization is currently monolithic, and the PMC has some clock inputs, so the init routine ends up calling of_clk_get_by_name(), and hence clocks must be set up early too. In order to defer clock initialization to the more typical location, split out the portions of tegra_pmc_init() that are truly IRQ-related into a separate tegra_pmc_init_irq(), which can be called from the machine descriptor's .init_irq() function, and defer the rest until the machine descriptor's .init_machine() function. This allows the clock initiliazation to happen from the machine descriptor's .init_time() function, as is typical. Signed-off-by: Stephen Warren

reboot: arm: change reboot_mode to use enum reboot_mode

2013-07-09T17:33:29+00:00

Preparing to move the parsing of reboot= to generic kernel code forces the change in reboot_mode handling to use the enum.

Pull clock framework updates from Mike Turquette: "The common clock framework changes for 3.11 include new clock drivers across several different platforms and architectures, fixes to existing drivers, a MAINTAINERS file fix and improvements to the basic clock types that allow them to be of use to more platforms than before. Only a few fixes to the core framework are included with most all of the changes landing in the various clock drivers themselves." * tag 'clk-for-linus-3.11' of git://git.linaro.org/people/mturquette/linux: (55 commits) clk: tegra: fix ifdef for tegra_periph_reset_assert inline clk: tegra: provide tegra_periph_reset_assert alternative clk: exynos4: Fix clock aliases for cpufreq related clocks clk: samsung: Add MUX_FA macro to pass flag and alias clk: add support for Rockchip gate clocks clk: vexpress: Make the clock drivers directly available for arm64 clk: vexpress: Use full node name to identify individual clocks clk: tegra: T114: add DFLL DVCO reset control clk: tegra: T114: add DFLL source clocks clk: tegra: T114: add FCPU clock shaper programming, needed by the DFLL clk: gate: add CLK_GATE_HIWORD_MASK clk: divider: add CLK_DIVIDER_HIWORD_MASK flag clk: mux: add CLK_MUX_HIWORD_MASK clk: Always notify whole subtree when reparenting MAINTAINERS: make drivers/clk entry match subdirs clk: honor CLK_GET_RATE_NOCACHE in clk_set_rate clk: use clk_get_rate() for debugfs clk: tegra: Use override bits when needed clk: tegra: override bits for Tegra30 PLLM clk: tegra: override bits for Tegra114 PLLM ...

ARM: tegra: cpuidle: move the init function behind the suspend init function

2013-06-05T17:44:53+00:00

One of the state of CPUidle on Tegra can power gate the CPU and the vdd_cpu rail. But it depends on some configurations from DT and a common hook function for different Tegra SoCs to power gate the CPU rail. And these stuffs are initialized after common Tegra suspend init function. So we move the CPUidle init behind the suspend init function. And making the CPUidle driver more generic.

Merge tag 'tegra-for-3.10-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/multiplatform

2013-04-09T14:55:15+00:00

From Stephen Warren : ARM: tegra: multi-platform conversion This branch converts Tegra to support multi-platform/single-zImage. One header is made accessible to drivers. The earlyprintk implementation is moved to the multi-platform location. Some Kconfig changes are made to enable multi-platform. Some dead files are deleted. The APIs exposed in the now-global tegra-powergate.h should be replaced with standard reset and power domain APIs in the future. This branch is based on (part of) the previous soc pull request. * tag 'tegra-for-3.10-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: ARM: tegra: convert to multi-platform ARM: tegra: move to Signed-off-by: Arnd Bergmann

ARM: tegra: pm: add platform suspend support

2013-04-03T20:31:41+00:00

Adding suspend to RAM support for Tegra platform. There are three suspend mode for Tegra. The difference were below. * LP2: CPU voltage off * LP1: CPU voltage off, DRAM in self-refresh * LP0: CPU + Core voltage off, DRAM in self-refresh After this patch, the LP2 suspend mode will be supported.

ARM: tegra: moving the CPU power timer function to PMC driver

2013-04-03T20:30:22+00:00

The CPU power timer set up function was related to PMC register. Now moving it to PMC driver. And it also help to clean up the PM related code later. The timer was calculated based on the input clock of PMC. In this patch, we also get the clock from DT. Signed-off-by: Joseph Lo Signed-off-by: Stephen Warren
