This patch series allows to tune VDD_LOG on RK3399-Q7 Puma boards using a PWM adjustable regulator.
The effect of the series is, that VDD_LOG will be set to about 950 mV on Puma. This is required to address stability issues on Puma. Christoph Muellner (4): rockchip: rk3399-puma: Cleanup vdd_log node in puma DTSI. power: regulator: Allow PWM regulator to be omitted from SPL. rockchip: defconfig: puma-rk3399: enable PWM regulator rockchip: puma-rk3399: Enable vdd-log during bootup. arch/arm/dts/rk3399-puma.dtsi | 5 +-- board/theobroma-systems/puma_rk3399/puma-rk3399.c | 43 +++++++++++++++++++++++ configs/puma-rk3399_defconfig | 1 + drivers/power/regulator/Kconfig | 7 ++++ drivers/power/regulator/Makefile | 2 +- 5 files changed, 53 insertions(+), 5 deletions(-) -- 2.11.0 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
