hte: tegra: Fix missing error code in tegra_hte_test_probe()

2023-11-20T10:59:08+00:00

[ Upstream commit b7c3ca3553d1de5e86c85636828e186d30cd0628 ] The value of 'ret' is zero when of_hte_req_count() fails to get number of entitties to timestamp. And returning success(zero) on this failure path is incorrect.

hte: Explicitly include correct DT includes

2023-08-28T18:31:06+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

hte: tegra-194: Use proper includes

2023-04-26T22:44:30+00:00

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.

2023-04-26T22:44:14+00:00

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

2023-04-26T22:43:57+00:00

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

2023-04-26T22:43:42+00:00

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.
