used. It provides 5 channels which can be independently
programmed. Channel 4 (the last) is normally used as a timer.
+config PWM_IMX
+ bool "Enable support for i.MX27 and later PWM"
+ help
+ This PWM is found i.MX27 and later i.MX SoCs.
+
config PWM_ROCKCHIP
bool "Enable support for the Rockchip PWM"
depends on DM_PWM
Various options provided in the hardware (such as capture mode and
continuous/single-shot) are not supported by the driver.
+config PWM_SANDBOX
+ bool "Enable support for the sandbox PWM"
+ help
+ This is a sandbox PWM used for testing. It provides 3 channels and
+ records the settings passed into it, but otherwise does nothing
+ useful. The PWM can be enabled but is not connected to any outputs
+ so this is not very useful.
+
config PWM_TEGRA
bool "Enable support for the Tegra PWM"
depends on DM_PWM
four channels with a programmable period and duty cycle. Only a
32KHz clock is supported by the driver but the duty cycle is
configurable.
+
+config PWM_SUNXI
+ bool "Enable support for the Allwinner Sunxi PWM"
+ depends on DM_PWM
+ help
+ This PWM is found on H3, A64 and other Allwinner SoCs. It supports a
+ programmable period and duty cycle. A 16-bit counter is used.
