From 394409aafd017adfcffd075595cb01cc456a9327 Mon Sep 17 00:00:00 2001 From: Guru Das Srinagesh Date: Wed, 24 Mar 2021 12:28:54 -0700 Subject: regmap-irq: Add driver callback to configure virtual regs Enable drivers to configure and modify "virtual" registers, which are non-standard registers that further configure irq type on some devices. Since they are non-standard, enable drivers to configure them according to their particular idiosyncrasies by specifying an optional callback function while registering with the framework.
