This format of PCH GPIOs configuration, unlike the raw DW0 and DW1 [1] registers values from the inteltool dump, is more understandable and makes the code much cleaner. The pad configuration in this patch was generated using the pch-pads-parser utility [2]. The inteltool dump before and after the patch is identical (see notes) Notes: 1. For some reason, GPIO RX State (RO) for the GPP_F4 and GPP_G10 changed the value to 0, but this doesn't affect the motherboard operation. Perhaps this is because PAD_CFG1_GPIO_DRIVER is set to PAD_CFG_GPI_INT(), and the pad is not actually connected. So far I haven't circuit diagram to check this out. 2. According to the documentation [1], the value 3h for RXEVCFG is implemented as setting 0h. 3. If the available macros from gpio_defs.h [3] can't determine the configuration of the pad, the utility [2] generates common _PAD_CFG_STRUCT() macros [1] page 1429,Intel (R) 100 Series and Intel (R) C230 Series PCH Family Platform Controller Hub (PCH), Datasheet, Vol 2 of 2, February 2019, Document Number: 332691-003EN [2] https://github.com/maxpoliak/pch-pads-parser/tree/stable_1.0 [3] src/soc/intel/common/block/include/intelblocks/gpio_defs.h Change-Id: I01ad4bd29235fbe2b23abce5fbaaa7e63c87f529 Signed-off-by: Maxim Polyakov <max.senia.poliak@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/33565 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Held <felix-coreboot@felixheld.de> |
