The driver has intel_lpss_platform_info structs for I2C, SPI, and UART. The I2C and UART structs are named with "i2c" and "uart" in the variable name, whereas SPI ones do not mention "spi". Rename the SPI related info structs to include "spi" in their names for consistency and to make it obvious in the device ID list what kind of device the line relates to.

2024-07-04mfd: intel_soc_pmic_crc: Use PWM_LOOKUP_WITH_MODULE() for the PWM lookupHans de Goede
The primary use of the CRC PMIC's PWM is for LCD panel backlight control by the i915 driver. Due to its complexity the probe() function of the i915 driver does not support -EPROBE_DEFER handling. So far the pwm-crc driver must be built into the kernel to ensure that the pwm_get() done by the i915 driver succeeds at once (rather then returning -EPROBE_DEFER). But the PWM core can load the module from pwm_get() if a module-name is provided in the pwm_lookup associated with the consumer device. Switch to using PWM_LOOKUP_WITH_MODULE() for the lookup added for the Intel integrated GPU, so that the PWM core can load the module from pwm_get() as needed allowing the pwm-crc driver to be safely built as module. This has been successfully tested on an Asus T100TAM with pwm-crc build as a module.

2024-07-04mfd: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

Replace FB_BLANK_ constants with their counterparts from the backlight subsystem. The values are identical, so there's no change in functionality. Only change the driver's backlight device, but leave the LCD device as-is.

2024-07-04backlight: Add BACKLIGHT_POWER_ constants for power statesThomas Zimmermann
Duplicate FB_BLANK_ constants as BACKLIGHT_POWER__ constants in the backlight header file. Allows backlight drivers to avoid including the fbdev header file and removes a compile-time dependency between the two subsystems. The new BACKLIGHT_POWER_ constants have the same values as their FB_BLANK_ counterparts. Hence UAPI and internal semantics do not change. The backlight drivers can be converted one by one. Each instance of FB_BLANK_UNBLANK becomes BACKLIGHT_POWER_ON, each of FB_BLANK_POWERDOWN becomes BACKLIGHT_POWER_OFF, and FB_BLANK_NORMAL becomes BACKLIGHT_POWER_REDUCED. Backlight code or drivers do not use FB_BLANK_VSYNC_SUSPEND and FB_BLANK_HSYNC_SUSPEND, so no new constants for these are being added. The semantics of FB_BLANK_NORMAL appear inconsistent. In fbdev, NORMAL means display off with sync enabled. In backlight code, this translates to turn the backlight off, but some drivers interpret it as backlight on. So we keep the current code as is, but mark BACKLIGHT_POWER_REDUCED as deprecated. Drivers should be fixed and the constant removed. This affects ams369fg06 and a few DRM panel drivers. v2: - rename BL_CORE_ power constants to BACKLIGHT_POWER_ (Sam) - fix documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org> Link: https://lore.kernel.org/r/20240624152033.25016-2-tzimmermann@suse.de Signed-off-by: Lee Jones <lee@kernel.org>
