From: Frieder Schrempf <frieder.schrempf@xxxxxxxxxx> This patchset fixes the control of the LDO5 regulator by providing an option for letting the driver know which of the two possible control registers is currently in use by the hardware. It also fixes the enable register for LDO5 to use PCA9450_REG_LDO5CTRL_L as specified by the datasheet. The last patch makes use of the fix by adjusting the devicetree for the Kontron i.MX8MM boards. In Linux this currently doesn't fix any functional issues, but in U-Boot similar changes are needed in order to fix SD card access.
