Subject: [PATCH v6 0/7] cpufreq: add generic cpufreq driver support for
Exynos542x/5800 platforms
Hi,
This patch series adds generic cpufreq-dt driver support for
Exynos542x/5800 (using the new CPU clock type which allows it).
It has been tested on Exynos5422 based ODROID-XU3 Lite board.
Depends on:
- next-20151211 branch of linux-next kernel tree
- "[PATCH] ARM: dts: Make CPU configuration more readable for
exynos542x/5800" patch (https://lkml.org/lkml/2015/12/11/107)
Changes since v5:
- rebased over next-20151211 branch (something is broken in
newer branches, namely next-2015121[45])
- rebased on top of "ARM: dts: Make CPU configuration more
readable for exynos542x/5800" patch
- renamed cpu0_opp_table to cluster_a15_opp_table and
cpu1_opp_table to cluster_a7_opp_table
- added Reviewed-by from Krzysztof
Changes since v4:
- renamed oppXX@hz to opp@hz
- put Odroid changes in exynos5422-odroidxu3-common.dtsi
- override CPU OPP properties for Exynos5422/5800 instead of
duplicating them
- merged "ARM: dts: Exynos5422: fix OPP tables" patch with
"ARM: dts: Exynos5420: add CPU OPP properties" one
- added missing Thomas' SoB line to "ARM: dts: Exynos5420:
add CPU OPP properties" patch
- updated authorship of "ARM: Exynos: use generic cpufreq
driver for Exynos5420" and "ARM: Exynos: use generic
cpufreq driver for Exynos5422/5800" patches
- updated Javier's and Mike's e-mail adresses
- removed non-working e-mail address of Sachin Kamat
Changes since v3:
- switched to using cpufreq-dt driver
- updated patch descriptions to cover Exynos5422 support
- added Acked-by from Sylwester to clock driver patches
Changes since v2:
- ported over next-20151124 branch
- integrated missing CLK_RECALC_NEW_RATES flags fix to patch #3
(from Anand Moon)
- added regulator supply properties for ODROID-XU3 Lite and
ODROID-XU4 in patch #2
- ported CPU OPPs to operating-points-v2 (from Ben Gamari)
- added "ARM: dts: Exynos5422: fix OPP tables" patch (from Ben
Gamari)
- added "cpufreq: arm-big-little: accept operating-points-v2
nodes" patch (from Ben Gamari)
- renamed OPP nodes as opp@<opp-hz>
Changes since v1:
- added CPU cluster regulator supply properties to
exynos5420-arndale-octa.dts, exynos5420-peach-pit.dts,
exynos5420-smdk5420.dts and exynos5800-peach-pi.dts
Changes over Thomas' original v12 code:
- split Exynos5420 and Exynos5800 support
- moved E5420_[EGL,KFC]_DIV0() macros to clk-exynos5420.c
- disabled cpufreq if big.LITTLE switcher support is enabled
- enhanced arm_big_little[_dt] driver with CPU cluster regulator
support
- fixed CPU clock configuration data for Exynos5800
- fixed CPU operating points setup for Exynos5800
- added CPU cluster regulator supplies for ODROID-XU3 board
Best regards,
