2013-11-26clk: tegra: move periph clocks to common filePeter De Schrijver
Introduce a new file for peripheral clocks common between several Tegra SoCs and move Tegra114 to this new infrastructure. Also PLLP and the PLLP_OUT clocks will be initialized here. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: move audio clk to common filePeter De Schrijver
Move audio clocks and PLLA initialization to a common file so it can be used by multiple Tegra SoCs. Also a new array tegra114_clks is introduced for Tegra114 which specifies which common clocks are available on Tegra114 and what their DT IDs are.

2013-11-26clk: tegra: add clkdev registration infraPeter De Schrijver
Add a common infra for registering clkdev. This allows decoupling clk registration from clkdev registration. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: add common infra for DT clocksPeter De Schrijver
Introduce a common infrastructure for sharing clock initialization between SoCs. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: add header for common tegra clock IDsPeter De Schrijver
Many clocks are common between several Tegra SoCs. Define an enum to list them so we can move them to separate files which can be shared between SoCs. Each SoC specific file will provide an array with the common clocks which are present on the SoC and their DT binding ID. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: move fields to tegra_clk_pll_paramsPeter De Schrijver
Move some fields related to the PLL HW description to the tegra_clk_pll_params. This allows some PLL code to be moved to common files later. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: use pll_ref as the pll_e parentPeter De Schrijver
Use pll_ref instead of pll_re_vco as the pll_e parent on Tegra114. Also add a 12Mhz pll_ref table entry for pll_e for Tegra114. This prevents the system from crashing at bootup because of an unsupported pll_re_vco rate. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: move some PLLC and PLLXC init to clk-pll.cPeter De Schrijver
VCO min clipping, dynamic ramp setup and IDDQ init can be done in the respective PLL clk_register functions if the parent is already registered. This is done for other some PLLs already. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: Add TEGRA_PERIPH_NO_DIV flagPeter De Schrijver
This flag indicates the peripheral clock does not have a divider. It will simplify the initialization tables and avoids some very similar code. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: common periph_clk_enb_refcnt and clksPeter De Schrijver
This patch makes periph_clk_enb_refcnt a global array, dynamically allocated at boottime. It simplifies the macros somewhat and allows clocks common to several Tegra SoCs to be defined in a separate files. Also the clks array becomes global and dynamically allocated which allows the DT registration to be moved to a generic funcion. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: simplify periph clock dataPeter De Schrijver
This patch determines the register bank for clock enable/disable and reset based on the clock ID instead of hardcoding it in the tables describing the clocks. This results in less data to be maintained in the tables, making the code easier to understand. The full benefit of the change will be realized once also other clocktypes will be table based. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: Fix clock rate computationThierry Reding
The PLL output frequency is multiplied during the P-divider computation, so it needs to be divided by the P-divider again before returning. This fixes an issue where clk_round_rate() would return the multiplied frequency instead of the real one after the P-divider. Signed-off-by: Thierry Reding <treding@nvidia.com>

2013-11-26clk: tegra: Set the clk parent of host1x to pll_pAndrew Chew
The power-on default parent for this clock is pll_m, which turns out to be wrong. Previously, bootloader reparented this clock. We'll do it in the kernel as well, so that there's one less thing that we depend on bootloader to initialize.

Well, it covered the function tracer by adding checks in __register_ftrace_function(). The problem is that the function graph tracer circumvents that (for a slight efficiency gain when function graph trace is running with a function tracer. The gain was not worth this). The problem came with ftrace_startup() which should always be called after __register_ftrace_function(), if you want this bug to be completely fixed. Anyway, this solution moves __register_ftrace_function() inside of ftrace_startup() and removes the need to call them both.

2013-11-25ARM: OMAP2+: Fix eMMC on n900 with device treeTony Lindgren
Looks like we need to configure the regulators and use the pdata quirk to make eMMC work with device tree. It seems that mostly vaux3 is used, and only some earlier revisions used vmmc2. This has been tested to work on devices where the system_rev passed by the bootloader has versions 0x0010, 0x2101 and 0x2204.

2013-11-25ARM: OMAP2+: Add fixed regulator to omap2plus_defconfigTony Lindgren
We do not have REGULATOR_FIXED selected if no boards are selected and we boot with device tree. This can cause various devices to fail. Signed-off-by: Tony Lindgren <tony@atomide.com>
2013-11-25ARM: OMAP2+: Fix more missing data for omap3.dtsi fileTony Lindgren
After dropping the duplicate data in hwmod that now should come from the .dts files, I noticed few more entries missing. Let's add these as otherwise devices relying on these won't work. Looks like the side tone entries are bundled into the mcbsp1 to 3, so that may needs some special handling in the hwmod code as it's currently trying to look up mcbsp2_sidetone and mcbsp3_sidetone entries.

2013-11-25ARM: vexpress/TC2: Implement MCPM power_down_finish()Dave Martin
This patch implements the power_down_finish() method for TC2, to enable the kernel to confirm when CPUs are safely powered down. The information required for determining when a CPU is parked cannot be obtained from any single place, so a few sources of information must be combined: * mcpm_cpu_power_down() must be pending for the CPU, so that we don't get confused by false STANDBYWFI positives arising from CPUidle. This is detected by waiting for the tc2_pm use count for the target CPU to reach 0. * Either the SPC must report that the CPU has asserted STANDBYWFI, or the TC2 tile's reset control logic must be holding the CPU in reset. Just checking for STANDBYWFI is not sufficient, because this signal is not latched when the the cluster is clamped off and powered down: the relevant status bits just drop to zero. This means that STANDBYWFI status cannot be used for reliable detection of the last CPU in a cluster reaching WFI. This patch is required in order for kexec to work with MCPM on TC2. MCPM code was changed in commit 0de0d6467525 ('ARM: 7848/1: mcpm: Implement cpu_kill() to synchronise on powerdown'), and since then it will hit a WARN_ON_ONCE() due to power_down_finish not being implemented on the TC2 platform.

The cpupower idle-set subcommand was introduce recently. This patch provides the missing manpage. If cpupower is properly installed it will show up automatically (similar to git), when invoking: cpupower help idle-set or cpupower idle-set --help Some parts have been taken over and adjusted from git commit 62d6ae880e3e76098 documentation submitted by Carsten Emde.

2013-11-25ARM: tegra: Provide dummy powergate implementationThierry Reding
In order to support increased build test coverage for drivers, implement dummies for the powergate implementation. This will allow the drivers to be built without requiring support for Tegra to be selected. This patch solves the following build errors, which can be triggered in v3.13-rc1 by selecting DRM_TEGRA without ARCH_TEGRA: drivers/built-in.o: In function `gr3d_remove': drivers/gpu/drm/tegra/gr3d.c:321: undefined reference to `tegra_powergate_power_off' drivers/gpu/drm/tegra/gr3d.c:325: undefined reference to `tegra_powergate_power_off' drivers/built-in.o: In function `gr3d_probe': drivers/gpu/drm/tegra/gr3d.c:266: undefined reference to `tegra_powergate_sequence_power_up' drivers/gpu/drm/tegra/gr3d.c:273: undefined reference to `tegra_powergate_sequence_power_up' Signed-off-by: Thierry Reding <treding@nvidia.com> [swarren, updated commit description] Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Olof Johansson <olof@lixom.net>
