-Subject: [PATCH] leds: pca963x: Fix open-drain initialization
-
-commit 697529091ac7a0a90ca349b914bb30641c13c753 upstream.
-
-Before commit bb29b9cccd95 ("leds: pca963x: Add bindings to invert
-polarity") Mode register 2 was initialized directly with either 0x01
-or 0x05 for open-drain or totem pole (push-pull) configuration.
-
-Afterwards, MODE2 initialization started using bitwise operations on
-top of the default MODE2 register value (0x05). Using bitwise OR for
-setting OUTDRV with 0x01 and 0x05 does not produce correct results.
-When open-drain is used, instead of setting OUTDRV to 0, the driver
-keeps it as 1:
-
-Open-drain: 0x05 | 0x01 -> 0x05 (0b101 - incorrect)
-Totem pole: 0x05 | 0x05 -> 0x05 (0b101 - correct but still wrong)
-
-Now OUTDRV setting uses correct bitwise operations for initialization:
-
-Open-drain: 0x05 & ~0x04 -> 0x01 (0b001 - correct)
-Totem pole: 0x05 | 0x04 -> 0x05 (0b101 - correct)
-
-Additional MODE2 register definitions are introduced now as well.
-
-Fixes: bb29b9cccd95 ("leds: pca963x: Add bindings to invert polarity")
