This series does the initial work to migrate sunxi boards to DM_I2C. Version 1 of this series bitrotted quite a bit, so there is some reorganization in version 2.
First it takes care of the PMIC: - Patches 1-2 clean up the PMIC Kconfig, though they are not strictly necessary after 7abf178b, and are independent from the other patches. - Patch 3 then adds a DM_PMIC driver. - Patches 4-6 prepare to move the P2WI/RSB bus drivers to drivers/i2c. - Patches 7-8 move and add DM_I2C versions of those two drivers. - Patches 9-10 migrate the "pmic_bus" functions to use the DM_I2C bus and DM_PMIC driver when possible. Then it takes care of the LCD panels: - Patch 11 converts those drivers to use DM_I2C. Finally, patch 12 switches all sunxi boards over to DM_I2C.
I have build-tested each commit on all sunxi boards.
There is some remaining work to clean up uses of pmic_bus in U-Boot proper and replace them with DM_PMIC functions: - drivers/gpio/axp_gpio.c - I have a series for this. - do_poweroff() in drivers/gpio/axp???.c - I have a series for this. - axp_get_sid() in drivers/power/axp221.c - Not sure what to do here. - axp_set_eldo() in drivers/video/sunxi/sunxi_display.c - This will need a DM_REGULATOR driver.
Changes in v2: - Rebase to pick up 7abf178b ("power: Tidy up #undef of CONFIG_DM_PMIC") - Rebase to pick up 7abf178b ("power: Tidy up #undef of CONFIG_DM_PMIC") - Replace axp_pmic_bind() with `.bind = dm_scan_fdt_dev` - New patch to account for I2C Kconfig changes - Renamed Kconfig symbol to SYS_I2C_SUN6I_P2WI - Moved entire P2WI driver source to drivers/i2c - Renamed Kconfig symbol to SYS_I2C_SUN8I_RSB - Moved entire RSB driver source to drivers/i2c - Update IS_ENABLEDs in pmic_bus.c to match chages to previous patches
