This patch series updates the tegra common clock driver and adds
support for the Tegra210 clocks. The clocks in Tegra210 changed
significantly in some ways from earlier generations, so to support
them, we need to extend our base framework a bit and add some new
features.
Some patches here also address issues found while adding features
and other cleanup type work.
Note this series does depend on
"clk: tegra: Fix comments for structure definitions"
which has been reviewed already.
v6:
- Add new clks for pllp_out* and xusb clks
- Fixed up UTMI programming for XUSB support
- Reordered patches to ensure bisectability
v5:
- Reorderd some patches
- Added Thierry's kerneldoc update patch as dependency
v4:
- Fixed minor checkpatch errors and other typos
- Rebased ontop of linux-next 20150504
v3:
- Added a fix from Andrew Bresticker that was found while testing
this code.

tegra_audio_clk_init was written expecting a single PLL to be
passed in directly. Change this to accept an array which will
allow for supporting multiple plls and specifying specific data
about them, like their parent, which may change over time.

1.7.9.5
Tegra210 has significant differences in muxes for peripheral clocks.
One of the most important changes is that pll_m isn't to be used
as a source for peripherals. Therefore, we need to define the new
muxes and new clocks to use those muxes for Tegra210 support.
Tegra210 has some differences in the PLLP clock tree:
- Four new output clocks: PLLP_OUT_CPU, PLLP_OUT_ADSP, PLLP_OUT_HSIO,
and PLLP_OUT_XUSB.
- PLLP_OUT2 is fixed at 1/2 the rate of PLLP_VCO.
- PLLP_OUT4 is the child of PLLP_OUT_CPU.
Update the xusb_hs_src mux and add the xusb_ssp_src mux for Tegra210.
Including work by Andrew Bresticker <[email protected]> and
Bill Huang <[email protected]>.

Create a wrapper interface to make use of the existing
clk_pll_wait_for_lock. This will be useful for implementations
of callbacks in Tegra SoC specific clock drivers.

Instead of having multiple similar wrapper functions for
_clk_pll_[enable|disable], we can simplify it to single
wrappers and use checks to avoid the logic we don't want to use.

- Moved the iddq settings into _clk_pll_enable/disable. This is because
some places in this file call directly into these internal functions,
but still need the iddq/reset logic to happen.

New SoC's may have more then 3 MISC registers, so bump up the
array size and use a #define to be more informative about the value.

SoC specific drivers should define the appropriate flags for each
PLL rather than relying on the registration functions to automatically
set flags on their behalf. This will properly allow for changes between
SoC generations where flags might be different and allow sharing the
same logic functions.

1.7.9.5
This adds logic for taking SDM_DIN (Sigma Delta Modulator) setting into
the equation to calculate the effective N value for PLL which supports
fractional divider.
The effective N = NDIV + 1/2 + SDM_DIN/2^13, where NDIV is the integer
feedback divider.

1.7.9.5
For Tegra210, the logic to calculate out-of-table rates is different
from previous generations. Add callbacks that can be overridden to
allow for different ways of calculating rates. Default to
_cal_rate when not specified.
This patch also includes a new flag which is used to set which method
of fixed_mdiv calculation is used. The new method for calculating the
fixed divider value for M can be more accurate especially when
fractional dividers are in play. This allows for older chipsets to use
the existing logic and new generations to use a newer version which
may work better for them.

1.7.9.5
From: Danny Huang <[email protected]>
PLLM is fixed for Tegra30 up through Tegra114. Starting with Tegra124
PLLM can change rate. Mark PLLM as TEGRA_PLL_FIXED for the generations
where it should be. Modify the check in clk_pll_round_rate and
clk_pll_recalc_rate to allow for the non-fixed version to
return the correct rate.
Note that clk-tegra20 is not touched. This is because PLL_M is not
distinguished in that driver, and adding either the PLL_M or FIXED_RATE
flags will cause potential problems.
PLLM never supported dynamic ramping. On T20/T30, there is no dynamic
ramping al all, and on T114/T124/T132, only PLLX and PLLC support
dynamic ramping, so we can go ahead and remove the specialized pllm_ops.

On Tegra210 SoC's, the logic to enable several of the plls is different
from previous generations. Therefore, add registration functions specific
to Tegra210 which will handle them appropriately.

v6:
- Removed setting up hw control for SATA PLL/XUSB
v5:
- Removed unused variables.
v4:
- Fixed plle_tegra210_is_enabled callback typos
v2:
- Fixed plle logic. PLLE on Tegra210 has had its enable bit moved, so
we can't use the default _clk_pll_enable/disable routines. Instead,
manually set/clear the correct bit for PLLE within its functions.

1.7.9.5
Tegra210 SoC's have 2 PLLS for memory usage. Add plumbing to register
and handle PLLMB.
PLLMB is used to allow switching between 2 PLLM's without having to use
and intermediate backup PLL, as we need to lock the PLL before we can
switch to it.

This code makes use of the SDM fractional divider if present to
constrain the allowable programming range of the PLL divider register
bitfields to take advantage of higher frequency granularity that can
be induced by the SDM divider.

This removes the conversion from pdiv to hw, which is already taken
care of by _get_table_rate before this code is run. This avoids
incorrectly converting pdiv to hw twice and getting the wrong hw value.
Also set the input_rate in the freq cfg in _calc_dynamic_ramp_rate while
setting all the other fields.

1.7.9.5
Implement clock support for Tegra210.
Signed-off-by: Rhyland Klein <[email protected]>
---
v6:
- Updated UTMI programming
- Added new clks (pllp_out*, xusb, etc)
- exported and used tegra_pll_p_div_to_hw
- changed set_defaults callbacks to print pll names for debugging purposes
- Combined init tables to just "init_table" since there is no need for the split
v5:
- Fixed UTMIP_PLL_CFG1/2 MACROS
- Added pr_warns for set_defaults when PLL is already enabled
- Changed vco_out member to flag instead (as it was simple boolean anyway)
- Switch to using clk72Mhz_8 for new mux
- Added usb2_hsic_trk, hsic_trk, and usb2_trk clks
- renamed pll_d_dsi -> pll_d_dsi_out
- Used ARRAY_SIZE for tegra_audio_clk_init
- Initialzed pll_dp to allow set_defaults to run properly
v4:
- Fixed checkpatch errors
- Fixed pllx_dyn_ramp error (missing ->params)
v3:
- Fixed pll_u hierarchy. PLL_U has a vco output now, and out1 and out2
clocks which are used to generate 60M and 48M clocks. VCO is used for
480M clock and the pll_u_out clock generates the 240M clock.
- Renamed pll_u -> pll_u_vco
- Removed 12M clock which doesn't exist anymore
- Renamed pll_re_c4_div_table -> pll_vco_post_div_table
- Set initial rates for pll_u_out1/2 for 48M/60M respectively.
v2:
- Fixed pll_a sdm_din_reg address (MISC0 -> MISC1)
- Fixed plld_set_defaults to not override DSI_CLKENABLE
- Fixed error in pll_e_freq table where cml divider was set into wrong field
- Removed freq comments based on previous review comments
- Removed freq for FPGA as suggested
- Added _pll_misc_chk_default inline function
- Fixed error in pllx dynamic ramp logic

+NVIDIA Tegra210 Clock And Reset Controller
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
+for muxing and gating Tegra's clocks, and setting their rates.
+
+Required properties :
+- compatible : Should be "nvidia,tegra210-car"
+- reg : Should contain CAR registers location and length
+- clocks : Should contain phandle and clock specifiers for two clocks:
+ the 32 KHz "32k_in".
+- #clock-cells : Should be 1.
+ In clock consumers, this cell represents the clock ID exposed by the
+ CAR. The assignments may be found in header file
+ <dt-bindings/clock/tegra210-car.h>.
+- #reset-cells : Should be 1.
+ In clock consumers, this cell represents the bit number in the CAR's
+ array of CLK_RST_CONTROLLER_RST_DEVICES_* registers.
+
+Example SoC include file:
+
+/ {
+ tegra_car: clock {
+ compatible = "nvidia,tegra210-car";
+ reg = <0x60006000 0x1000>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+ usb@c5004000 {
+ clocks = <&tegra_car TEGRA210_CLK_USB2>;
+ };
+};
+
+Example board file:
+
+/ {
+ clocks {
+ compatible = "simple-bus";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ clk_32k: clock@1 {
+ compatible = "fixed-clock";
+ reg = <1>;
+ #clock-cells = <0>;
+ clock-frequency = <32768>;
+ };
+ };
+
+ &tegra_car {
+ clocks = <&clk_32k>;
+ };
+};

From: Andrew Bresticker <[email protected]>
Without this change clk_get_rate would return the final output
rather than the VCO output as it would factor in the pdiv when
it shouldn't. This will cause problems for all dividers in the
subtree of the VCO PLL.

From: Andrew Bresticker <[email protected]>
On Tegra210, hardware control of the SATA and XUSB pad PLLs must be
done during the UPHY enable sequence rather than the PLLE enable
sequence. Export functions to do this so that hardware control can
be enabled from the XUSB padctl driver.
