2025-05-16memory: omap-gpmc: Switch to irq_domain_create_linear()Jiri Slaby (SUSE)
irq_domain_add_linear() is going away as being obsolete now. Switch to the preferred irq_domain_create_linear(). That differs in the first parameter: It takes more generic struct fwnode_handle instead of struct device_node. Therefore, of_fwnode_handle() is added around the parameter. Note some of the users can likely use dev->fwnode directly instead of indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not guaranteed to be set for all, so this has to be investigated on case to case basis (by people who can actually test with the HW).

2024-12-22memory: tegra20-emc: fix an OF node reference bug in ↵Joe Hattori
tegra_emc_find_node_by_ram_code() As of_find_node_by_name() release the reference of the argument device node, tegra_emc_find_node_by_ram_code() releases some device nodes while still in use, resulting in possible UAFs. According to the bindings and the in-tree DTS files, the "emc-tables" node is always device's child node with the property "nvidia,use-ram-code", and the "lpddr2" node is a child of the "emc-tables" node. Thus utilize the for_each_child_of_node() macro and of_get_child_by_name() instead of of_find_node_by_name() to simplify the code. This bug was found by an experimental verification tool that I am developing.

aemif_calc_rate() checks the validity of a new computed timing against a 'max' value given as input. This isn't convenient if we want to check the CS timing configuration somewhere else in the code. Wrap the verification of all the chip select's timing configuration into a single function to ease its exportation in upcoming patches. Remove the validity check from aemif_calc_rate(). Also remove the no longer used 'max' input and change the return type to u32. Remove the check of the aemif_calc_rate()'s return value during device-tree parsing as aemif_calc_rate() can't fail anymore.

2024-12-09memory: ti-aemif: Store timings parameter in number of cycles - 1Bastien Curutchet
The CS configuration register expects timings to be expressed in 'number of cycles - 1' but they are stored in ns in the struct aemif_cs_data. So at init, the timings currently set are converted to ns by aemif_get_hw_params(), updated with values from the device-tree properties, and then converted back to 'number of cycles - 1' before being applied. Store the timings directly in 'number of cycles - 1' instead of nanoseconds. Perform the conversion from nanosecond during the device-tree parsing. Remove aemif_cycles_to_nsec() as it isn't used anymore.

2024-12-01Get rid of 'remove_new' relic from platform driver structLinus Torvalds
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
