From 9b15062cc05dbfec8092f5f08ac734fd29ed7b5a Mon Sep 17 00:00:00 2001 From: Matti Vaittinen Date: Thu, 26 Sep 2024 15:01:13 +0300 Subject: [PATCH] mfd: rtc: bd7xxxx Drop IC name from IRQ A few ROHM PMICs have an RTC block which can be controlled by the rtc-bd70528 driver. The RTC driver needs the alarm interrupt information from the parent MFD driver. The MFD driver provides the interrupt information as a set of named interrupts, where the name is of form: -rtc-alm-, where x is an alarm block number. >From the RTC driver point of view it is irrelevant what the PMIC name is. It is sufficient to know this is alarm interrupt for a block X. The PMIC model information is carried to RTC via the platform device ID. Hence, having the PMIC model in the interrupt name is only making things more complex because the RTC driver needs to request differently named interrupts on different PMICs, making code unnecessary complicated. Simplify this slightly by always using the RTC driver name 'bd70528' as the prefix for alarm interrupts, no matter what the exact PMIC model is, and always request the alarm interrupts of same name no matter what the PMIC model is.
