Subject: [PATCH 0/3] gpio: shared: close remaining gaps

This series fixes some remaining issues and corner-cases in the shared
GPIO management. In order to address multiple shared GPIOs per consumer
as well as the reset-gpio interaction, we need to support multiple
lookup tables per consumer device.

This is targetting v6.19 as it effectively fixes the code that went
upstream during the v6.19 merge window.

Bartosz Golaszewski (3):
      gpiolib: allow multiple lookup tables per consumer
      gpio: shared: verify con_id when adding proxy lookup
      gpio: shared: allow sharing a reset-gpios pin between reset-gpio and gpiolib
