2020-04-03mb/google/auron: Convert variants to use override devicetreeMatt DeVillier
Since the variants' devicetrees are almost identical, convert to using an overridetree setup for simplicity. As part of the cleanup, drop unused PCIe RP5 for buddy as well. Test: build all auron variants, compare generated static.c to ensure resulting generated contents unchanged (although layout will) Change-Id: I290e7243335a64afdcfc629db7b8ce18f5aa993c Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39940 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com>
2019-10-16intel/broadwell: Implement proper backlight PWM configNico Huber
Port the backlight-PWM handling from Skylake instead of the previously used Haswell version. We use a 200Hz PWM signal for all boards. Which is higher than the previous devicetree value, 183Hz, but that was over- ridden by the VBIOS anyway. 200Hz is still very low, considering LED backlights, but accurate values are unknown at this time. Lynx Point, the PCH for Haswell and Broadwell, is a transition point for the backlight-PWM config. On platforms with a PCH, we have: o Before Lynx Point: The CPU has no PWM pin and sends the PWM duty-cycle setting to the PCH. The PCH can choose to ignore that and use its own setting (BLM_PCH_OVERRIDE_ENABLE). We use the CPU setting on these platforms. o Lynx Point + Haswell: The CPU has an additional PWM pin but can be set up to send its setting to the PCH as before. The PCH can still choose to ignore that. We use the CPU setting with Haswell. o Lynx Point + Broadwell: The CPU can't send its setting to the PCH anymore. BLM_PCH_ OVERRIDE_ENABLE must always be set(!) if the PCH PWM pin is used (it virtually always is). We have to use the PCH setting in this case. o After Lynx Point: Same as with Broadwell, only BLM_PCH_OVERRIDE_ENABLE is implied and the bit not implemented anymore.

2018-08-03mb/google/auron,cyan: Remove interrupt from devicetree LPC TPM chip driverMatt DeVillier
These boards require polling vs interrupts, so remove the IRQ definition to prevent it being added to the SSDT device entry. Test: Boot Linux on various auron and cyan variants, verify no error for 'TPM interrupt not working' present in kernel boot log.

2016-12-22Add/Combine Broadwell Chromebooks using variant board schemeMatt DeVillier
Combine existing boards google/auron_paine and google/samus with new ChromeOS devices auron_yuna, gandof and lulu, using their common reference board (auron) as a base. Chromium sources used: firmware-yuna-6301.59.B 6ed8b9d [CHERRY-PICK: broadwell: Update to...] firmware-gandof-6301.155.B 666f34f [gandof: modify power limiting for...] firmware-lulu-6301.136.B 8811714 [lulu: update RAMID table] Additionally, some minor cleanup/changes were made: - I2C devices set to use level (vs edge) interrupt triggering - HDA verb entries use simplified macro entry format - correct FADT table header version - remove unused ACPI device entries / .asl file(s) - clean up ACPI code (e.g., trackpad on Lulu) - adjust _CID for trackpad on Lulu in order to not load non-functional Windows driver (does not affect Linux) - remove unused header includes (multiple/various) - correct I2C addresses used for SMBIOS device entries - correct misc typos etc The existing auron_paine samus boards are removed.
