2023-08-15Merge patch series "Introduce Intel Tangier pinctrl driver"Andy Shevchenko
Raag Jadav <raag.jadav@intel.com> says: Merrifield and Moorefield pinctrl driver implementations are similar in terms of how they access the hardware. We can consolidate their pinctrl functionalities into a common library driver. This patch set introduces: 1. Intel Tangier driver that supports the common pinctrl functionalities for Merrifield and Moorefield platforms. 2. Intel Tangier adaptation for Merrifield pinctrl driver. 3. Intel Tangier adaptation for Moorefield pinctrl driver. Tested on Intel Edison platform. No deviation observed in the contents of below entries before and after this patchset. - /proc/interrupts - /sys/kernel/debug/gpio - /sys/kernel/debug/pinctrl/*/pins Link: https://lore.kernel.org/r/20230814054033.12004-1-raag.jadav@intel.com Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
