config DM_I2C
bool "Enable Driver Model for I2C drivers"
depends on DM
I2C or LPC). Some Chromebooks use this when the hardware design
does not allow direct access to the main PMIC from the AP.
+config I2C_CROS_EC_LDO
+ bool "Provide access to LDOs on the Chrome OS EC"
+ depends on CROS_EC
+ ---help---
+ On many Chromebooks the main PMIC is inaccessible to the AP. This is
+ often dealt with by using an I2C pass-through interface provided by
+ the EC. On some unfortunate models (e.g. Spring) the pass-through
+ is not available, and an LDO message is available instead. This
+ option enables a driver which provides very basic access to those
+ regulators, via the EC. We implement this as an I2C bus which
+ emulates just the TPS65090 messages we know about. This is done to
+ avoid duplicating the logic in the TPS65090 regulator driver for
+ enabling/disabling an LDO.
config DM_I2C_GPIO
bool "Enable Driver Model for software emulated I2C bus driver"
bindings are supported.

+config SYS_I2C_FSL
+ bool "Freescale I2C bus driver"
+ depends on DM_I2C
+ help
+ Add support for Freescale I2C busses as used on MPC8240, MPC8245, and
+ MPC85xx processors.

+config SYS_I2C_CADENCE
+ tristate "Cadence I2C Controller"
+ depends on DM_I2C && (ARCH_ZYNQ || ARM64)
+ help
+ Say yes here to select Cadence I2C Host Controller. This controller is
+ e.g. used by Xilinx Zynq.
+
+config SYS_I2C_DW
+ bool "Designware I2C Controller"
+ default n
+ help
+ Say yes here to select the Designware I2C Host Controller. This
+ controller is used in various SoCs, e.g. the ST SPEAr, Altera
+ SoCFPGA, Synopsys ARC700 and some Intel x86 SoCs.
+
+config SYS_I2C_DW_ENABLE_STATUS_UNSUPPORTED
+ bool "DW I2C Enable Status Register not supported"
+ depends on SYS_I2C_DW && (TARGET_SPEAR300 || TARGET_SPEAR310 || \
+ TARGET_SPEAR320 || TARGET_SPEAR600 || TARGET_X600)
+ default y
+ help
+ Some versions of the Designware I2C controller do not support the
+ enable status register. This config option can be enabled in such
+ cases.
+
+config SYS_I2C_INTEL
+ bool "Intel I2C/SMBUS driver"
+ depends on DM_I2C
+ help
+ Add support for the Intel SMBUS driver. So far this driver is just
+ a stub which perhaps some basic init. There is no implementation of
+ the I2C API meaning that any I2C operations will immediately fail
+ for now.
+
+config SYS_I2C_ROCKCHIP
+ bool "Rockchip I2C driver"
+ depends on DM_I2C
+ help
+ Add support for the Rockchip I2C driver. This is used with various
+ Rockchip parts such as RK3126, RK3128, RK3036 and RK3288. All chips
+ have several I2C ports and all are provided, controled by the
+ device tree.

config SYS_I2C_SANDBOX
bool "Sandbox I2C driver"
depends on SANDBOX && DM_I2C
Support for UniPhier FIFO-builtin I2C controller driver.
This I2C controller is used on PH1-Pro4 or newer UniPhier SoCs.
+config SYS_I2C_MVTWSI
+ bool "Marvell I2C driver"
+ depends on DM_I2C
+ help
+ Support for Marvell I2C controllers as used on the orion5x and
+ kirkwood SoC families.
