2023-08-06drivers: Add SPDX license headers to MakefilesMartin Roth
To help identify the licenses of the various files contained in the coreboot source, we've added SPDX headers to the top of all of the .c and .h files. This extends that practice to Makefiles. Any file in the coreboot project without a specific license is bound to the license of the overall coreboot project, GPL Version 2. This patch adds the GPL V2 license identifier to the top of all makefiles in the drivers directory that don't already have an SPDX license line at the top.

2022-11-18drivers/i2c/rv3028c7: Add ACPI generation callbacksJan Samek
Add ACPI generation callback to the driver after obtaining the ACPI HID "MCRY3028" for this device from Microcrystal AG (VID: "MCRY"). Also add I2C bus speed field to the device config structure, which is a required ACPI entry. BUG=none TEST=Disassemble the SSDT table and see whether the device entry "MC28" is generated correctly. Also check whether the RV3028 driver in Linux (drivers/rtc/rtc-rv-3028.c) is bound correctly after adding an ACPI match table to it containing the HID. A proper kernel patch is pending.

This patch adds a driver for a new RTC from Micro Crystal. Supported features are: * configure backup voltage switchover via devicetree * configure backup capacitor charging mode via devicetree * set date if a voltage drop on backup voltage was detected to either a user definable (devicetree) or coreboot build date Change-Id: I37176ea726e50e4e74d409488981d7618ecff8bb Signed-off-by: Werner Zeh <werner.zeh@siemens.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/67099 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Mario Scheithauer <mario.scheithauer@siemens.com>
