Renesas RZ/G2L gpt supports output pin disable function by dead time error and detecting short-circuits between output pins. There are 4 poeg groups shared between gpt channels. This patch adds support for linking poeg group with gpt channel, so that gpt channel can control the output disable function through poeg module(port output enable for gpt) v2->v3: * Moved minItems/MaxItems one level up in bindings. * Updated commit header and description for the driver * Added check for poeg group in rzg2l_gpt_parse_properties(). v1->v2: * removed quotes from ref * Added maxItems and minItems for renesas,poegs property * Added enums for gpt index * Replaced id->poeg-id as per poeg bindings in patch#3. patch#1 is just added to avoid bot errors.
