Merge series "Add pca9450 driver" from Robin Gong <yibin.gong@nxp.com>:
Add pca9450 driver for i.mx8mn-evk board. PCA9450A/B/C supported now.
Please refer to below link for PCA9450 datasheet:
https://www.nxp.com/docs/en/data-sheet/PCA9450DS.pdf
v2:
1. rebase with the latest code to use linear_ranges helper instead.
2. address Frieder's comments, such as dulipcated buck4 description,
debug info added etc.
