Most PMIC-s use only a single i2c-address, so after verifying the i2c-address matches, we can simply pass the call to regmap_update_bits. This commit adds support for this and hooks this up for the xpower AXP288 PMIC by setting the new pmic_i2c_address field. This fixes the following errors on display on / off on a Jumper Ezpad mini 3 and an Onda V80 plus tablet, both of which use the AXP288: intel_soc_pmic_exec_mipi_pmic_seq_element: Not implemented intel_soc_pmic_exec_mipi_pmic_seq_element: i2c-addr: 0x34 reg-addr ... [drm:mipi_exec_pmic [i915]] *ERROR* mipi_exec_pmic failed, error: -95 Instead of these errors on both devices we now correctly turn on / off DLDO3 (through direct register manipulation). On the Onda V80 plus this fixes an issue with the backlight being brighter around the borders after an off / on cycle. This should also help to save some power when the display is off.
