Changes were tested atop the current linux tree (v3.15-rc1). FET retries were tested on a machine with a known flaky tps65090. Since display isn't working on pure upstream, I augmented the code to turn FET1 (vcd_led) on/off 500 times at bootup. When testing I included <https://patchwork.kernel.org/patch/3980731/> to make sure tps65090 was in exynos5250-snow's device tree. Dependencies: - Patch #1 (mfd no irq) has no dependencies, though patch #2 won't work without it. - Patch #2 (charger polling) can be applied without patch #1 but won't actually make charger polling work without it. - Patch #3 (caching) can be applied before retries patch but not after. - Patch #4 (overcurrent wait time) can be applied before retries patch but not after (just due to merge conflicts, no other reason). - Patch #5 (retries) absolutely requires patch #3 (caching). Changes in v2: - Split noirq (polling mode) changes into MFD and charger - Leave cache on for the registers that can be cached. - Move register offsets to mfd header file. - Separated the overcurrent and retries changes into two patches. - Now set overcurrent at probe time since it doesn't change. - Separated the overcurrent and retries changes into two patches. - No longer open code fet_is_enabled(). - Fixed tps6090 typo. - For loop => "while true". - Removed a set of braces.
