From 0b271258544b3f89f9a14fa3b53e20ec9ce75392 Mon Sep 17 00:00:00 2001 From: Beomho Seo Date: Tue, 9 Dec 2014 21:03:51 +0900 Subject: mfd: rt5033: Add Richtek RT5033 driver core. This patch adds a new driver for Richtek RT5033 driver. RT5033 is a Multifunction device which includes battery charger, fuel gauge, flash LED current source, LDO and synchronous Buck converter. It is interfaced to host controller using I2C interface.

This patch provides suspend and resume functions for the DLN2 driver so that the above scenario is avoided, if the host controller does not drop VBUS during suspend, since in this case the device state is preserved. We chose not implemented reset_resume so that if the host controller does drop VBUS the resume path will go through above the disconnect/reconnect process since it is probably better to fix the GPIO framework disconnect issue then to save and restore the device state for every driver.

After removal of board file support from max77686 and max77802 regulator drivers, the MFD driver can be converted to DTS-only version. This simplifies a little the code: 1. No dead (unused) entries in platform_data structure. 2. More code removed. 3. Regulator driver does not depend on allocated memory from MFD driver. 4. It makes also easier extending the regulator driver. Add to the max77686 MFD driver dependency on CONFIG_OF because without DTS the regulator drivers (max77686 and max77802) won't bind.

Under current 1-HZ polling interval setting in mmc_core, the worst case of such undetectablility is about 1 second. To further reduce the undetectability, detect card slot again in suspend method and defer the autosuspend if the slot is loaded. The default 2 second autosuspend delay of USB subsystem should let the next polling detects the card.
