Subject: Tegra: PLL: use per-SoC pllinfo table instead of PLL_DIVM/N/P, etc.
X-Git-Tag: KARO-TX6-2015-09-18~854
X-Git-Url: https://git.kernelconcepts.de/?a=commitdiff_plain;h=80b1150680938e4164c6203de80e676357a93dfc;p=karo-tx-uboot.git

Tegra: PLL: use per-SoC pllinfo table instead of PLL_DIVM/N/P, etc.

Added PLL variables (dividers mask/shift, lock enable/detect, etc.)
to new pllinfo struct for each Soc/PLL. PLLA/C/D/E/M/P/U/X.

Used pllinfo struct in all clock functions, validated on T210.
Should be equivalent to prior code on T124/114/30/20. Thanks
to Marcel Ziswiler for corrections to the T20/T30 values.
