2023-10-24drivers/wwan/fm: Wake up modem on PEWAKE# signal changePaweł Anikiel
Create an event handler for the PEWAKE# GPIO and notify the device driver to wake up the device. BUG=b:301150499 TEST=Compiled and tested on google/redrix: 1. Enable runtime suspend for linux mtk_t7xx driver 2. Wait for device to enter suspended state 3. Modem should be able to wake up driver, e.g. on SIM card insert/eject The interrupts should show up under /proc/interrupts as ACPI:Event Signed-off-by: Paweł Anikiel <panikiel@google.com> Change-Id: I32257689da85ea71f9de781093b3ede0cfe70a0e Reviewed-on: https://review.coreboot.org/c/coreboot/+/78297 Reviewed-by: Jakub Czapiga <czapiga@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
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.
