Merge tag 'gpio-fixes-for-v6.10-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
"Two OF lookup quirks and one fix for an issue in the generic gpio-mmio
driver:
- add two OF lookup quirks for TSC2005 and MIPS Lantiq
- don't try to figure out bgpio_bits from the 'ngpios' property in
gpio-mmio"
* tag 'gpio-fixes-for-v6.10-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
gpiolib: of: add polarity quirk for TSC2005
gpio: mmio: do not calculate bgpio_bits via "ngpios"
gpiolib: of: fix lookup quirk for MIPS Lantiq
