On K3 SoCs the A53 cluster does not own device power, clocks, resets or interrupt routing; these are managed by the DM/TIFS firmware and requested over TISCI through the secure-proxy mailbox. Add: - a TISCI client (secure-proxy transport plus device/clock/reset helpers) - a GPIO driver for banks 0/1 with pad mux and TISCI power-on - an OMAP-I2C driver for the main-domain I2C controllers and wire them into the PocketBeagle2 and BeaglePlay bring-up. Tested on PocketBeagle2 (SYSFW 11.2.5) with the TechLab cape attached: nsh> i2c bus nsh> i2c dev -b 0 0x03 0x77 # I2C0 detects onboard 0x20 and 0x50 nsh> gpio -o 1 /dev/gpio3 # drives a user LED; read back with: nsh> gpio /dev/gpio3 Signed-off-by: Piyush Patle <piyushpatle228@gmail.com>
