* soc/amd/cezanne: Turn off gpp clock request for disabled devicesRobert Zieba2022-03-231-5/+7
| | | | | | | | | | | | | | | | | | | | The current behavior does not actually check if a device is present before enabling the corresponding gpp_clkx_clock_request_mapping bits which may cause issues with L1SS. This change sets the corresponding gpp_clkx_clock_request_mapping to off if the corresponding device is disabled. BUG=b:202252869 TEST=Checked that value of GPP_CLK_CNTRL matched the expected value when devices are enabled/disabled, checked that physically removing a device that is marked as enabled also disables the corresponding clk req BRANCH=guybrush Signed-off-by: Robert Zieba <robertzieba@google.com> Change-Id: I77389372c60bdec572622a3b49484d4789fd4e4c Reviewed-on: https://review.coreboot.org/c/coreboot/+/61259 Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
* soc/amd/*/i2c: factor out common I2C pad configurationFelix Held2022-02-031-1/+2
| | | | | | | | | | | | | | | The I2C pad control registers of Picasso and Cezanne are identical and the one of Sabrina is a superset of it, so factor out the functionality. To avoid having devicetree settings that contain raw register bits, the i2c_pad_control struct is introduced and used. The old Picasso code for this had the RX level hard-coded for 3.3V I2C interfaces, so keep it this way in this patch but add a TODO for future improvements.

| | | | | | | | | | | | | | Since we need the GPIO defines in the devicetree settings, include gpio.h in each SoC's chip.h file which will indirectly include the soc-specific soc/gpio.h header instead of having it indirectly included via soc/i2c.h.

* soc/amd/*/chip.h: Correct PSPP Enum ValueMatt Papageorge2021-07-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | It appears the pspp_policy enum is not the same as the FSP definition currently being used. This means that the incorrect PSPP value setting would get read by FSP. For Zork programs this meant we actually were setting links as DXIO_PSPP_BALANCED instead of DXIO_PSPP_POWERSAVE. This change adds DXIO_PSPP_DISABLED as the first enum value to properly match the FSP definition and adjusts non AMD Customer Reference Boards that reference the enum to still send the same value even though it has now change definitions. If we actually want DXIO_PSPP_POWERSAVE for those boards that can be adjusted in a future change.

* soc/amd/cezanne: Configure I2C Pad RX Select through devicetreeKarthikeyan Ramasubramanian2021-06-071-0/+1
| | | | | | | | | | | | | | | | | | | Some of the I2C buses are required to operate at different voltage level compared to other I2C buses eg. I2C bus to Google Security Chip (GSC) should be at 1.8V level. By default, all the I2C buses are initialized to operate at 3.3 V. Add support to configure I2C pad RX select through devicetree and update the concerned devicetree. BUG=b:188538373 TEST=Build and boot to OS in Guybrush. Ensure that the communication with GSC is fine. Build Majolica mainboard.

* soc/amd/cezanne/fch: add PCIe GPP clock generator configuration settingsFelix Held2021-05-191-0/+9
| | | | | | | | | | | | | | | | | | I'm not 100% sure if this should rather be duplicated from Picasso or commonized. Checked with the docs and this won't be compatible with Stoneyridge and one future product's PPR lacked the corresponding register. Some other chip has a compatible register layout, but a different number of PCIe GPP clock outputs, so the common code would need to use some SoC-dependent defines and possibly a SoC-specific lookup table for the mapping which is also not that great.
