clk: tegra: dfll: CVB calculation alignment with the regulator

2019-02-06T13:28:41Z

The CVB table contains calibration data for the CPU DFLL based on process characterization. The regulator step and offset parameters depend on the regulator supplying vdd-cpu, not on the specific Tegra SKU. When using a PWM controlled regulator, the voltage step and offset are determined by the regulator type in use. This is specified in DT. When using an I2C controlled regulator, we can retrieve them from CPU regulator Then pass this information to the CVB table calculation function. Based on the work done of "Peter De Schrijver " and "Alex Frid ". Signed-off-by: Joseph Lo Acked-by: Jon Hunter Acked-by: Stephen Boyd Signed-off-by: Thierry Reding

clk: tegra: dfll: improve function-level documentation

2016-11-02T00:38:50Z

Adjust variables to correspond to the names used in the parameter list of the function. Move the struct device * variable up to the place where it appears in the parameter list. Issue detected using Coccinelle (http://coccinelle.lip6.fr/) Signed-off-by: Julia Lawall Signed-off-by: Stephen Boyd

clk: tegra: dfll: Properly clean up on failure and removal

2016-04-28T10:41:54Z

Upon failure to probe the DFLL, the OPP table will not be cleaned up properly. Fix this and while at it make sure the OPP table will also be cleared upon driver removal. Signed-off-by: Thierry Reding

clk: tegra: dfll: Make code more comprehensible

2016-04-28T10:41:53Z

Rename some variables and structure fields to make the code more comprehensible. Also change the prototype of internal functions to be more in line with the OPP core functions. Signed-off-by: Thierry Reding

clk: tegra: Unlock top rates for Tegra124 DFLL clock

2015-09-15T10:54:39Z

The new determine_rate prototype allows for clock rates exceeding 2^31-1 Hz to be used. Switch the DFLL clock to use determine_rate instead of round_rate and unlock the top rates supported by the Tegra124. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

clk: tegra: Add functions for parsing CVB tables

2015-07-16T07:32:47Z

Tegra CVB tables encode the relationship between operating voltage and optimal frequency as a function of the so-called speedo value. The speedo value is written to the on-chip fuses at the factory, which allows the voltage-frequency operating points to be calculated on an per-chip basis. Add utility functions to parse the Tegra-specific tables and export the voltage-frequency pairs to the generic OPP framework for other drivers to use.
