[PATCH v2 1/2] pinctrl: renesas: rzg2l: Introduce single macro for digital noise filter configuration

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

Support for enabling the digital noise filter, and support for
configuring the noise filter stages (via the FILNUM register) and the
sampling interval (via the FILCLKSEL register) are related: a pin
supports either all or none of them. Hence simplify declaring digital
noise filter support for a pin by using a single feature flag instead of
three separate flags.

This patch removes the PIN_CFG_FILNUM and PIN_CFG_FILCLKSEL configuration
macros and renames PIN_CFG_FILONOFF to PIN_CFG_NF.
