2014-02-03ARM: tegra: pass just partition ID to power_partition()Stephen Warren
Pass just the partition ID to power_partition(), rather than also passing the partition's status register mask too. This makes it simpler to get call-sites correct, since they don't need to pass two different values that define the same thing and must match. Consequently, we can remove the mask definitions from pmc.h.

2014-02-03ARM: tegra: don't exceed AVP limits when configuring PLLPJimmy Zhang
Based on the Tegra TRM, the system clock (which is the AVP clock) can run up to 275MHz. On power on, the default sytem clock source is set to PLLP_OUT0. In function clock_early_init(), PLLP_OUT0 will be set to 408MHz which is beyond system clock's upper limit. The fix is to set the system clock to CLK_M before initializing PLLP, and then switch back to PLLP_OUT4, which has an appropriate divider configured, after PLLP has been configured Implement this logic in new function tegra30_set_up_pllp(), which sets up PLLP and all PLLP_OUT* dividers, and handles the AVP clock switching. Remove the duplicate PLLP setup from pllx_set_rate() and adjust_pllp_out_freqs().

2014-02-03ARM: tegra: amend pmc.h for Tegra114+Stephen Warren
Tegra114 and later's PMC module removes the pwrgate_timer_on register and replaces it with a clamp_status register. Adjust pmc.h to reflect this, and update any code affected by the change. The cpu.c change in this patch was extracted from a much larger patch by Jimmy Zhang. The pmc.h change was written from scratch, but inspired by related changes made by Tom Warren. There could well be other differences in the PMC register set for chips after Tegra20/30. However, they don't affect the code in U-Boot at present, so I haven't attempted an exhaustive update of pmc.h.

2014-02-03ARM: tegra: MASK_BITS_ no longer needs specific valuesStephen Warren
Since all code that sets or interprets MASK_BITS_* now uses the enums to define/compare the values, there is no need for MASK_BITS_* to have a specific integer value. In fact, having a specific integer value may encourage people to hard-code those values, or interpret the values in incorrect ways. As such, remove the logic that assigns a specific value to the enum values in order to make it completely clear that it's just an enum, not something that directly represents some integer value.

2014-02-03ARM: tegra: use MASK_BITS_* macros everywhereStephen Warren
Not all code that set or interpreted "mux_bits" was using the named macros, but rather some was simply using hard-coded integer constants. This makes it hard to determine which pieces of code are affected by changes to those constants. Replace the integer constants with the equivalent macro definitions so that everything is nicely tied together. Note that I'm not convinced all the code was using the correct integer constants, and hence I'm not convinced that all the code is now using the desired macros. However, this change is a purely mechanical replacement and should have no functional change. Fixing any bugs will come later, separately.

2014-02-03ARM: tegra: rename OUT_CLK_SOURCE_*Stephen Warren
OUT_CLK_SOURCE_ are currently named after the number of bits the mask they represent includes. However, bit count is not the only possible variable; bit position may also vary. Rename OUT_CLK_SOURCE_ to OUT_CLK_SOURCE_31_30_ and OUT_CLK_SOURCE4_ to OUT_CLK_SOURCE_31_28 to more completely describe exactly what they represent, without having to go look up the definitions.

2014-02-03ARM: tegra: rename MASK_BITS_29_28 to MASK_BITS_31_28Stephen Warren
The only place where the MASK_BITS_* values are used is in adjust_periph_pll(), which interprets the value 4 (old MASK_BITS_29_28, new MASK_BITS_31_28) as being associated with mask OUT_CLK_SOURCE4_MASK, i.e. bits 31:28. Rename the MASK_BITS_ macro to reflect how it's actually implemented. Note that no Tegra clock register actually uses all of bits 31:28 as the mux field. Rather, bits 30:28, 29:28, or 28 are used. However, in those cases, nothing is stored in the bits above the mux field, so it's safe to pretend that the mux field extends all the way to the end of the register. As such, the U-Boot clock driver is currently a bit lazy, and doesn't distinguish between 31:28, 30:28, 29:28 and 28; it just lumps them all together and pretends they're all 31:28. This patch doesn't cause this issue; it was pre-existing. Hopefully, future patches will clean this up.

2014-02-03ARM: tegra: deduplicate MASK_BITS_xxx clock mux enumTom Warren

2014-02-03ARM: tegra: accept any SKU ID for most chipsStephen Warren
For Tegra20, the SKU ID actually impacts how U-Boot programs the chip, and hence we need to explicitly know about each and every SKU ID in order to operate correctly. However, for Tegra30/114, this isn't the case. Rather than forcing each new user with a different SKU to manually add their SKU ID into the code, simply accept any SKU ID. If U-Boot ever starts e.g. programming maximal CPU clocks etc., we'll need to undo this, or make the default case map to conservative defaults, but for now it's likely the path to least support cost.
