Signed-off-by: Jarkko Nikula Reviewed-by: Andi Shyti --- v3: Drop the idea to call this as Meteor Point-S in code since it's confusing. Intel Meteor Lake-S platform can have the SMBus controller both in SoC die and PCH. I decided earlier to call latter as Meteor Point-S since it fitted nicely into i801_ids table and I saw it to be used somewhere in internal documentation. But it's more historical naming convension for PCHs and to be honest internal documentation uses mostly Meteor Lake PCH-S. v2: "SOC/PCH" -> "SOC and PCH" in documentation and Kconfig. PCI ID define according to updated patch 1/2. --- Documentation/i2c/busses/i2c-i801.rst | 2 +- drivers/i2c/busses/Kconfig | 2 +- drivers/i2c/busses/i2c-i801.c | 3 +++ 3 files changed, 5 insertions(+), 2 deletions(-) diff --git a/Documentation/i2c/busses/i2c-i801.rst b/Documentation/i2c/busses/i2c-i801.rst index ab9e850e8fe0..e76e68ccf718 100644 --- a/Documentation/i2c/busses/i2c-i801.rst +++ b/Documentation/i2c/busses/i2c-i801.rst @@ -46,7 +46,7 @@ Supported adapters: * Intel Emmitsburg (PCH) * Intel Alder Lake (PCH) * Intel Raptor Lake (PCH) - * Intel Meteor Lake (SOC) + * Intel Meteor Lake (SOC and PCH) Datasheets: Publicly available at the Intel website diff --git a/drivers/i2c/busses/Kconfig b/drivers/i2c/busses/Kconfig index 87600b4aacb3..3144ef99f040 100644 --- a/drivers/i2c/busses/Kconfig +++ b/drivers/i2c/busses/Kconfig @@ -157,7 +157,7 @@ config I2C_I801 Emmitsburg (PCH) Alder Lake (PCH) Raptor Lake (PCH) - Meteor Lake (SOC) + Meteor Lake (SOC and PCH) This driver can also be built as a module.
