Hi,
This patch series adds generic arm_big_little_dt cpufreq driver
support for Exynos542x/5800 (using the new CPU clock type which
allows it). It also:
- enhances arm_big_little[_dt] driver with CPU cluster regulator
support
- adds CPU clock configuration data and CPU operating points
setup for Exynos542x/5800
- adds CPU cluster regulator supplies for Exynos542x/5800 boards
This patch series has been tested on Exynos5422 based ODROID-XU3
Lite board.
Please note that this is not a final version of the patchset.
I just wanted to push out current work-in-progress patches that
integrate changes from Anand, Ben and me.
TODO:
- porting the Exynos542x/5800 support over cpufreq-dt
Depends on:
- next-20151124 branch of linux-next kernel tree
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,
