Input: Switch i2c drivers back to use .probe()

2023-05-17T16:59:11Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

Input: drv260x - fix magnitude handling

2023-05-02T00:07:12Z

First of all, previously the 16-bit magnitude was written as-is to the device which actually discarded the upper 8 bits since the device has 8-bit registers only. This meant that a strong_magnitude of 0xFF00 would result in 0. To correct this shift the strong_magnitude / weak_magnitude input values so we discard the lower 8 bits and keep the upper bits instead. Secondly the RTP mode that is used by default interprets the values as signed (2s complement), so 0x81 = 0%, 0x00 = 50%, 0x7F = 100%. This doesn't match the FF_RUMBLE interface at all, so let's tell the device to interpret the data as unsigned instead which gets us 0x00 = 0% and 0xFF = 100%. As last change switch ERM to using "Closed-Loop Mode, Unidirectional" instead of "Open-Loop Mode" since it's recommended by the datasheet compared to open loop and better matches our use case of 0% - 100% vibration.

Input: drv260x - remove unused .reg_defaults

2023-05-02T00:07:10Z

Since the driver has disabled regmap caching with REGCACHE_NONE, it's warning us that we provide defaults that are not used. Remove them.

Input: drv260x - sleep between polling GO bit

2023-05-02T00:07:09Z

When doing the initial startup there's no need to poll without any delay and spam the I2C bus. Let's sleep 15ms between each attempt, which is the same time as used in the vendor driver.

Input: drv260x - switch to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()

2023-01-10T04:25:20Z

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings.
