2019-05-08T11:50:06+00:00

Add support for Maxim 77663 using the Max77620 driver. The hardware is very similar to Max77663/20024, although there are couple minor differences. Signed-off-by: Dmitry Osipenko Signed-off-by: Lee Jones

mfd: Use of_node_name_eq() for node name comparisons

2019-01-03T08:32:42+00:00

Convert string compares of DT node names to use of_node_name_eq() helper instead. This removes direct access to the node name pointer. Signed-off-by: Rob Herring Signed-off-by: Lee Jones

mfd: max77620: Fix FPS switch statements

2016-06-30T06:44:23+00:00

When configuring FPS during probe, assuming a DT node is present for FPS, the code can run into a problem with the switch statements in max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely, in the case of chip->chip_id == MAX77620, it will set fps_[mix|max]_period but then fall through to the default switch case and return -EINVAL. Returning this from max77620_config_fps() will cause probe to fail.

mfd: max77620: Mask/unmask interrupt before/after servicing it

2016-06-29T09:14:38+00:00

The programming guidelines of the MAX77620 for servicing interrupt is: 1. When interrupt occurs from PMIC, mask the PMIC interrupt by setting GLBLM. 2. Read IRQTOP and service the interrupt. 3. Once all interrupts has been checked and serviced, the interrupt service routine un-masks the hardware interrupt line by clearing GLBLM. Add the pre and post interrupt service handler for mask and unmask the global interrupt mask bit (for step 1 and 3) as callback from regmap-irq.
