MIPS: Alchemy: convert from round_rate() to determine_rate()

2025-08-29T20:34:29+00:00

The round_rate() clk ops is deprecated, so migrate this driver from round_rate() to determine_rate() using the Coccinelle semantic patch appended to the "under-the-cut" portion of the patch. Note that prior to running Coccinelle, alchemy_clk_aux_roundr() was renamed to alchemy_clk_aux_round_rate(). A few minor style cleanups were also done by hand.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

MIPS: alchemy: gpio: use new GPIO line value setter callbacks for the remaining chips

2025-07-28T06:03:08+00:00

Previous commit missed two other places that need converting, it only came out in tests on autobuilders now. Convert the rest of the driver.

struct gpio_chip now has callbacks for setting line values that return an integer, allowing to indicate failures. Convert the driver to using them. Signed-off-by: Bartosz Golaszewski Reviewed-by: Linus Walleij Signed-off-by: Thomas Bogendoerfer

MIPS: Remove unused function dump_au1000_dma_channel() in dma.c

MIPS: Alchemy: Use kcalloc() instead of kzalloc()

2024-02-20T12:36:34+00:00

As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the purpose specific kcalloc() function instead of the argument size * count in the kzalloc() function.

MIPS: Alchemy: Fix missing prototypes

2024-01-22T09:32:36+00:00

We have a number of missing prototypes warnings for board_setup(), alchemy_set_lpj() and prom_init_cmdline(), prom_getenv() and prom_get_ethernet_addr(). Fix those by providing definitions for the first two functions in au1000.h which is included everywhere relevant, and including prom.h for the last three.
