Add missing 2.0GHz, 1.9GHz & 1.8GHz OPPs (for A15 cores) and 1.4GHz OPP (for A7 cores). Also update common Odroid-XU3 Lite/XU3/XU4 thermal cooling maps to account for new OPPs. Since some new OPPs are not available on all Exynos5422/5800 boards modify dts files for Odroid XU3 Lite (limited to 1.8 GHz / 1.3 GHz) & Peach Pi (limited to 2.0 GHz / 1.3 GHz) accordingly. This patch uses maximum voltages for new OPPs. This is a temporary solution till proper Exynos ASV support is added. Also while at it fix the number of cooling down steps for big cores (should be 11 instead of 12 on Odroid XU3 Lite and 14 on XU3/XU4). Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> [mszyprow: rebased onto v5.5-rc1 and adapted to recent dts changes, fixed removal of the 1.4GHz OPP for A7s on Peach-Pi] Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
