From: Andre Przywara Date: Thu, 9 May 2024 23:43:18 +0000 (+0100) Subject: power: pmic: sunxi: add AXP717 SPL support X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=51bee9b5a349b5f39ed39f650e07d16a1b22004f;p=u-boot.git power: pmic: sunxi: add AXP717 SPL support On boards using the AXP717 PMIC, the DRAM rail is often not setup correctly at reset time, so we have to program the PMIC very early in the SPL, before running the DRAM initialisation. Using the new generic AXP SPL driver, add the Kconfig options and platform bits needed to support an AXP717 PMIC chip in I2C mode. This allows to set up the correct voltage for the DRAM chips and the CPU cores.
