2013-11-28clk: tegra: fix __clk_lookup() return value checksWei Yongjun
In case of error, the function __clk_lookup() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-28clk: tegra: Do not print errors for clk_round_rate()Thierry Reding
clk_round_rate() can be used by drivers to determine whether or not a frequency is supported by the clock. The current Tegra clock driver outputs an error message and a stacktrace when the requested rate isn't supported. That's fine for clk_set_rate(), but it's confusing when all the driver does is query whether or not a frequency is supported. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-11-27clk: socfpga: Remove check for "reg" property in socfpga_clk_initDinh Nguyen
The function socfpga_clk_init() can support clocks that do not have a divider register, but a fixed-divider that can be read from DTS. Therefore, the "reg" property is not a failing condition for socfpga_clk_init(). Signed-off-by: Dinh Nguyen <dinguyen@altera.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
2013-11-27clk: fixed-factor: Fix device-tree binding typoEzequiel Garcia
The required properties are not named "div" and "mult", but rather "clock-div" and "clock-mult". Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
2013-11-27clk: clean up everything on debugfs errorAlex Elder
[Maybe the third time will be the charm. -Alex] If CONFIG_COMMON_CLK_DEBUG is defined, clk_debug_create_one() is called to populate a debugfs directory with a few entries that are common for all clock types. If an error happens after creating the first one debugfs_remove() is called on the clock's directory. The problem with this is that no cleanup is done on the debugfs files already created in that directory, so the directory never actually gets removed. This problem is silently ignored. Fix this by calling debugfs_remove_recursive() instead. Reset the clk->dentry field to null afterward, to ensure it can't be mistaken as a valid pointer.

2013-11-26clk: tegra: Initialize DSI low-power clocksThierry Reding
The low-power DSI clocks are used during host-driven transactions on the DSI bus. Documentation recommends that they be children of PLLP and run at a frequency of at least 52 MHz. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-11-26clk: tegra: add FUSE clock deviceAlexandre Courbot
This clock is needed to ensure the FUSE registers can be accessed without freezing the system. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com>
2013-11-26clk: tegra: Properly setup PWM clock on Tegra30Thierry Reding
The clock for the PWM controller is slightly different from other peripheral clocks on Tegra30. The clock source mux field start at bit position 28 rather than 30. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-11-26clk: tegra: Initialize secondary gr3d clock on Tegra30Thierry Reding
There are two GPUs on Tegra30 and each of them uses a separate clock, so the secondary clock needs to be initialized in order for the gr3d module to work properly. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-11-26clk: tegra114: Initialize clocks needed for HDMIMikko Perttunen

2013-11-26clk: tegra124: add suspend/resume function for tegra_cpu_car_opsJoseph Lo
Adding suspend/resume function for tegra_cpu_car_ops. We only save and restore the setting of the clock of CoreSight. Other clocks still need to be taken care by clock driver.

2013-11-26clk: tegra124: add wait_for_reset and disable_clock for tegra_cpu_car_opsJoseph Lo
Hook the functions for CPU hotplug support. After the CPU is hot unplugged, the flow controller will handle to clock gate the CPU clock. But still need to implement an empty function to avoid warning message. Cc: Mike Turquette <mturquette@linaro.org> Signed-off-by: Joseph Lo <josephl@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. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra: add clkdev registration infraPeter De Schrijver

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>
2013-11-26ARM: tegra30: add missing CLK IDsPeter De Schrijver
The Tegra30 clock bindings lack few IDs for audio and clk_out muxes. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-26clk: tegra114: Rename gr_2d/gr_3d to gr2d/gr3dThierry Reding
These clocks were named gr2d and gr3d on Tegra20 and Tegra30, so use the same names on Tegra114 for consistency. Signed-off-by: Thierry Reding <treding@nvidia.com> Acked-by: Stephen Warren <swarren@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.

2013-11-26clk: tegra: add TEGRA_DIVIDER_ROUND_UP for periph clksPeter De Schrijver
Perform upwards rounding when calculating dividers for periph clks on Tegra30 and Tegra114. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-25clk: tegra: Set the clock parent of gr2d/gr3d to pll_c2Mark Zhang
pll_m will be the parent of gr2d/gr3d if we don't do this. And because pll_m runs at a high rate so gr2d/gr3d will be unstable. So change the parent of them to pll_c2. Signed-off-by: Mark Zhang <markz@nvidia.com> Acked-By: Peter De Schrijver <pdeschrijver@nvidia.com>
2013-11-25clk: tegra: Fix vde/2d/3d clock src offsetMark Zhang
In Tegra114, vde/gr_2d/gr_3d have 3 bits for clock source selection. So change the clock init macro for these clocks from "TEGRA_INIT_DATA_INT" to "TEGRA_INIT_DATA_INT8". Besides, no one uses "TEGRA_INIT_DATA_INT" after this change, so remove this macro.

2013-11-25clk: tegra: replace enum tegra114_clk by binding headerPeter De Schrijver
As the clock IDs are now specified in a header file, we can use those definitions instead of maintaining an internal enum. Signed-off-by: Peter De Schrijver <pdeschrijver@nvidia.com>
