Subject: [PATCH] mfd: Kconfig: change INTEL_SOC_PMIC_CHTDC_TI to bool
The INTEL_SOC_PMIC_CHTDC_TI should be initialized early, before
loading the fbcon driver, as otherwise the i915 driver will
fail to configure pwm:
[ 13.674287] fb0: switching to inteldrmfb from EFI VGA
[ 13.682380] Console: switching to colour dummy device 80x25
[ 13.682468] i915 0000:00:02.0: vgaarb: deactivate vga console
[ 13.682686] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[ 13.685773] i915 0000:00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem
[ 13.686219] i915 0000:00:02.0: [drm] *ERROR* Failed to configure the pwm chip
[ 13.699572] [drm] Initialized i915 1.6.0 20200313 for 0000:00:02.0 on minor 0
[ 13.739044] fbcon: i915drmfb (fb0) is primary device
[ 14.037792] intel_soc_pmic_exec_mipi_pmic_seq_element: No PMIC registered
...
[ 24.621403] intel_pmic_install_opregion_handler: Ask to register OpRegion for bus ID=PMI2, HID=INT33F5
[ 24.630540] intel_pmic_install_opregion_handler: OpRegion registered
(some extra debug printk's were added to the above)
As suggested by Hans, this patch also addresses an issue with
the dependencies, as, for this driver to be a bool, it also
need the I2C core and the I2C_DESIGNWARE driver to be builtin.
