Subject: [PATCH V2 0/3] add support for cherryview gpio controller driver
Date: Tue, 31 Aug 2021 01:07:33 -0400 [thread overview]
Message-ID: <20210831050736.5371-1-hongzhan.chen@intel.com> (raw)
1. move out of OF config conditional compilation so that non-OF platform
call same API to remove rtdm gpio chip device and remove _of for api
name.
2. Introduce helper to find gpiochip as referring to pair of
rtdm_gpiochip_scan_of and rtdm_gpiochip_scan_array_of.
3. Add Intel Cherryview pinctrl driver based on on 1 and 2.
I also did following tests with this patchset:
1. run /usr/lib/xenomai/testsuite/gpiobench -i 334 -i 335 -c INT33FF:02
to validate patch 9afea5ff2d7ba97db96b22a005a9a7fcf5f2d892 when
setting GPIO_RTIOC_TS
2. apply following patch, and rerun 1.

3. test result for inner related output:

Hardware env:
1. Rock PI X V1.4.
2. GPIO loopback connection between GPIO 334 and 335.
