From: Quentin Schulz <[email protected]> This simplifies the "depends on" since we don't need DM_PWM listed explicitly there as it already is made explicit via the surrounding "if". No intended change in behavior.
Signed-off-by: Quentin Schulz <[email protected]> --- Note that I believe PWM_SANDBOX should also depend on DM_PWM but I'm not sure how to make sure of that. The PWM sandbox test is explicitly only built when DM_PWM=y instead of SANDBOX_PWM=y (is that another issue?). --- drivers/pwm/Kconfig | 136 ++++++++++++++++++++++++++-------------------------- 1 file changed, 67 insertions(+), 69 deletions(-) diff --git a/drivers/pwm/Kconfig b/drivers/pwm/Kconfig index ec57a967721..218c861ae43 100644 --- a/drivers/pwm/Kconfig +++ b/drivers/pwm/Kconfig @@ -11,75 +11,12 @@ config DM_PWM frequency/period can be controlled along with the proportion of that time that the signal is high. -config PWM_ASPEED - bool "Enable support for the Aspeed PWM" - depends on DM_PWM - select SYSCON - help - This PWM is found on Ast2600 SoCs.
