The existing values are rejected by the da9063 regulator driver, as they are unachievable with the declared chip setup (non-merged vcore and bmem are unable to provide the declared curent). Fix voltages to match rev3 schematics, which also matches their boot-up configuration within the chip's available precision. Declare bcore1/bcore2 and bmem/bio as merged. Set ldo09 and ldo10 as always-on as their consumers are not declared but exist. Drop ldo current limits as there is no current limit feature for these regulators in the DA9063. Fixes warnings like: DA9063_LDO3: Operation of current configuration missing Signed-off-by: Vincent Pelletier <plr.vincent@gmail.com> -- Changes since v1: - Remove trailing "." on subject line. --- .../boot/dts/sifive/hifive-unmatched-a00.dts | 84 ++++++------------- 1 file changed, 24 insertions(+), 60 deletions(-)
