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: BCM63XX: Replace strcpy() with strscpy() in board_prom_init()

strcpy() is deprecated; use strscpy() instead. Link: https://github.com/KSPP/linux/issues/88 Cc: linux-hardening@vger.kernel.org Signed-off-by: Thorsten Blum Signed-off-by: Thomas Bogendoerfer

MIPS: bcm63xx: gpio: use new line value setter callbacks

2025-04-27T07:21:21+00:00

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

gpiolib: legacy: Kill GPIOF_INIT_* definitions

2024-09-02T09:47:06+00:00

Besides the fact that (old) drivers use wrong definitions, e.g., GPIOF_INIT_HIGH instead of GPIOF_OUT_INIT_HIGH, shrink the legacy definitions by killing those GPIOF_INIT_* completely.

mips: bmips: setup: make CBR address configurable

2024-06-27T08:44:32+00:00

Add support to provide CBR address from DT to handle broken SoC/Bootloader that doesn't correctly init it. This permits to use the RAC flush even in these condition. To provide a CBR address from DT, the property "brcm,bmips-cbr-reg" needs to be set in the "cpus" node. On DT init, this property presence will be checked and will set the bmips_cbr_addr value accordingly. Also bmips_rac_flush_disable will be set to false as RAC flush can be correctly supported. The CBR address from DT will overwrite the cached one and the one set in the CBR register will be ignored. Also the DT CBR address is validated on being outside DRAM window.

mips: bmips: rework and cache CBR addr handling

2024-06-27T08:44:24+00:00

Rework the handling of the CBR address and cache it. This address doesn't change and can be cached instead of reading the register every time. This is in preparation of permitting to tweak the CBR address in DT with broken SoC or bootloader. bmips_cbr_addr is defined in setup.c for each arch to keep compatibility with legacy brcm47xx/brcm63xx and generic BMIPS target.

MIPS: BCM63XX: Fix missing prototypes

Most of the symbols for which we do not have a prototype can actually be made static and for the few that cannot, there is already a declaration in a header for it. Signed-off-by: Florian Fainelli Signed-off-by: Thomas Bogendoerfer

MIPS: BCM63xx: Add check for NULL for clk in clk_enable
