pwm: sysfs: Replace sprintf() with sysfs_emit()

2022-09-28T15:52:02Z

While the uses in this code are unproblematic, it's generally safer for sysfs outputs to use the new sysfs_emit() helper instead of raw calls to sprintf() and friends. This also has the benefit of annotating the uses, which makes them easier to audit and potentially use them to generate sysfs documentation from them. This patch replaces existing sprintf() calls straightforwardly with the new helper. Signed-off-by: Andy Shevchenko Reviewed-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: core: Replace custom implementation of device_match_fwnode()

2022-09-28T14:54:25Z

Replace custom implementation of the device_match_fwnode(). This hides the implementation details and makes future changes easier. Signed-off-by: Andy Shevchenko Signed-off-by: Thierry Reding

pwm: lpss: Add a comment to the bypass field

2022-09-28T14:21:46Z

Add a comment to the bypass field based on the commit b997e3edca4f ("pwm: lpss: Set enable-bit before waiting for update-bit to go low"). Signed-off-by: Andy Shevchenko Reviewed-by: Hans de Goede Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: lpss: Make use of bits.h macros for all masks

2022-09-28T14:19:43Z

Make use of the GENMASK() (far less error-prone, far more concise). Signed-off-by: Andy Shevchenko Reviewed-by: Hans de Goede Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: lpss: Use DEFINE_RUNTIME_DEV_PM_OPS() and pm_ptr() macros

2022-09-28T14:18:57Z

Using these new macros allows the compiler to remove the unused dev_pm_ops structure and related functions if !CONFIG_PM without the need to mark the functions __maybe_unused. Signed-off-by: Andy Shevchenko Reviewed-by: Hans de Goede Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: lpss: Use device_get_match_data() to get device data

2022-09-28T14:18:11Z

device_get_match_data() in ACPI case calls similar to the acpi_match_device(). We may simplify the code and make it generic by replacing the latter with the former. Signed-off-by: Andy Shevchenko Reviewed-by: Hans de Goede Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: lpss: Move resource mapping to the glue drivers

2022-09-28T14:10:35Z

Move resource mapping to the glue drivers which helps to transform pwm_lpss_probe() to pure library function that may be used by others without need of specific resource management. Signed-off-by: Andy Shevchenko Reviewed-by: Hans de Goede Acked-by: Uwe Kleine-König Signed-off-by: Thierry Reding

pwm: lpss: Move exported symbols to PWM_LPSS namespace

2022-09-28T14:08:51Z

Avoid unnecessary pollution of the global symbol namespace by moving library functions in to a specific namespace and import that into the drivers that make use of the functions.
