clk: davinci: psc: drop unused reset lookup

2025-11-18T16:52:54+00:00

We no longer support any non-DT DaVinci boards so there are no more users of legacy reset lookup. Signed-off-by: Bartosz Golaszewski Acked-by: Stephen Boyd Acked-by: David Lechner Signed-off-by: Philipp Zabel

clk: Fix typos

clk: davinci: Add NULL check in davinci_lpsc_clk_register()

2025-06-19T23:48:09+00:00

devm_kasprintf() returns NULL when memory allocation fails. Currently, davinci_lpsc_clk_register() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue and ensuring no resources are left allocated.

clk: davinci: Use of_get_available_child_by_name()

2025-05-06T21:46:00+00:00

Simplify of_davinci_pll_init() by using of_get_available_child_by_name(). While at it, move of_node_put(child) inside the if block to avoid additional check if of_child is NULL.

clk: davinci: remove support for da830

2025-03-13T20:17:41+00:00

This SoC has some leftover code all over the kernel but no boards are supported anymore. Remove support for da830 from the davinci clock driver. With it: remove the ifdefs around the data structures as the da850 remains the only davinci SoC supported and the only user of this driver.

clk: davinci: remove platform data struct

2024-12-17T18:53:06+00:00

There are no board files using struct davinci_pll_platform_data anymore. The structure itself is currently used to store a single pointer. Let's remove the struct definition, the header and rework the driver to not require the syscon regmap to be stored in probe().

da8xx-cfgchip.c: replace of_node_put with __free improves cleanup

2024-07-29T23:12:50+00:00

The use of the __free function allows the cleanup to be based on scope instead of on another function called later. This makes the cleanup automatic and less susceptible to errors later. This code was compiled without errors or warnings.

clk: davinci: da8xx-cfgchip: Initialize clk_init_data before use

2024-07-18T20:33:01+00:00

The flag attribute of the struct clk_init_data isn't initialized before the devm_clk_hw_register() call. This can lead to unexpected behavior during registration. Initialize the entire clk_init_data to zero at declaration.

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers.
