* pinctrl: renesas: rzg2l: Add support to get/set drive-strength and ↵Lad Prabhakar2021-11-151-48/+113
| | | | | | | | | | | | | | | | | output-impedance-ohms RZ/G2L supports two groups of pins Group-A and Group-B. For Group-A pins drive-strength can be configured and for Group-B output-impedance can be configured. This patch splits PIN_CFG_IOLH macro to PIN_CFG_IOLH_A/B and adds support to get/set drive-strength and output-impedance-ohms for the supported pins.
