hte: tegra-194: Use proper includes

2023-04-26T22:44:30Z

The test driver uses the gpiod consumer API so include the right header. This may cause a problem with struct of_device_id being implcitly pulled in by the legacy header so include explicitly as well. While at it, drop explicit moduleparam.h (it's included with module.h) and sort the headers.

hte: Use device_match_of_node()

hte: tegra-194: Fix off by one in tegra_hte_map_to_line_id()

2023-04-26T22:44:14Z

The "map_sz" is the number of elements in the "m" array so the > comparison needs to be changed to >= to prevent an out of bounds read. Fixes: 09574cca6ad6 ("hte: Add Tegra194 HTE kernel provider") Signed-off-by: Dan Carpenter Acked-by: Dipen Patel Signed-off-by: Dipen Patel

hte: Use of_property_present() for testing DT property presence

2023-04-26T22:43:57Z

It is preferred to use typed property access functions (i.e. of_property_read_ functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

hte: handle nvidia,gpio-controller property

2023-04-26T22:43:42Z

The dt binding adds nvidia,gpio-controller property from Tegra234 SoC onwards to simplify code handling gpio chip search. The gpio chip search is needed for the AON GPIO GTE instances to map the hardware timestamp GPIO request (coming from the GPIO framework) to the tegra HTE providers. The patch also adds new gpio chip match function to match from the fwnode instead of the gpio controller label. The addition of the property does not break ABI for the existing Tegra194 code.

hte: Deprecate nvidia,slices property

The relevant DT bindings deprecates nvidia,slices property from Tegra234 SoC onwards, moving the slices value per SoC data structure instead. Signed-off-by: Dipen Patel

hte: Add Tegra234 provider

2023-04-26T22:43:26Z

The Tegra234 AON GPIO instance and LIC IRQ support HTE. For the GPIO HTE support, it also requires to add mapping between GPIO and HTE framework same as it was done with Tegra194 SoC. Signed-off-by: Dipen Patel
