2019-12-26soc/intel/cannonlake: Move GPIO PM configuration to soc levelEric Lai
Enable GPIO clock gating when enter s0ix/Sx and save the PM bits. Restore the PM bits when exit s0ix/Sx. BUG=b:144002424 TEST=Check GPIO PM bits when enter/exit s0ix are expected Signed-off-by: Eric Lai <ericr_lai@compal.corp-partner.google.com> Change-Id: I120f8369b8d3cf7ac821332bdfa124f6ed0570e9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/37685 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
2019-07-11soc/intel/cannonlake: Add GPID and CGPM methods to GPIO ASLTim Wawrzynczak
The GPID method returns the PCR Port ID of the given GPIO community. The CGPM method alters the given GPIO community's PM bits, given in Arg1.

2019-01-03soc/intel/cannonlake: Add cannonlake ACPI GPIO opLijian Zhao
Follow instrcution from https://doc.coreboot.org/acpi/gpio.html to implement GPIO toggling method, covered for both CNP_LP and CNP_H pch. BUG=N/A TEST=Build and boot up fine on sarien platform, add an dummy STSX in DSDT table, read back from iotools to confirm the GPIO tx state get updated.

2018-12-10soc/intel/cannonlake: Fix GPIO reportingDuncan Laurie
The kernel GPIO driver only expects some GPIO communities to be exported in the _CRS and it will not work correctly if the other communities are exported. CNL-LP: GPIO communities 0, 1, 4 CNL-H: GPIO communities 0, 1, 3, 4 Additionally one of the pin offset values was incorrect in GPIO community 1 for CNL-LP. This doesn't have any specific failure mode but it was found when auditing the GPIO code. Details of the kernel expected map can be found in the linux kernel at drivers/pinctrl/intel/pinctrl-cannonlake.c BUG=b:120686247 TEST=check /sys/kernel/debug/pinctrl/INT34BB:00/pins to ensure that pins >= 198 are not reading all zeros for the pin config registers.

2018-02-16soc/intel/cannonlake: Update GPIO ASLLijian Zhao
GPIO pin definition had been updated to match Cannonlake PCH-LP EDS, hence the ACPI dsdt table will include those changes as well. BUG=None TEST=Build coreboot image, flah coreboot image into DUT, and target system can boot up into OS.
