Hello,
I'm looking at the available options to support overlays in the display
pipeline of the i.MX7. The LCDIF itself unfortunaltey doesn't support
overlays, the feature being implemented in the PXP. A driver for the PXP
is available but only supports older SoCs whose PXP doesn't support

Rename the PM8941* references as WLED3 to make the driver
generic and have WLED support for other PMICs. Also rename
"i_boost_limit" and "i_limit" variables to "boost_i_limit"

This patch series renames the pm8941-wled.c driver to qcom-wled.c to add
the support for multiple PMICs supported by qualcomm. This patch series
supports both PM8941 and PMI8998 WLED. The PMI8998 WLED has the support
