- First part of DT header detangling dropping cpu.h from of_device.h and replacing some includes with forward declarations. A handful of drivers needed some adjustment to their includes as a result. - Refactor of_device.h to be used by bus drivers rather than various device drivers. This moves non-bus related functions out of of_device.h. The end goal is for of_platform.h and of_device.h to stop including each other. - Refactor open coded parsing of "ranges" in some bus drivers to use DT address parsing functions - Add some new address parsing functions of_property_read_reg(), of_range_count(), and of_range_to_resource() in preparation to convert more open coded parsing of DT addresses to use them. - Treewide clean-ups to use of_property_read_bool() and of_property_present() as appropriate. The ones here are the ones that didn't get picked up elsewhere. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEktVUI4SxYhzZyEuo+vtdtY28YcMFAmRIOrkACgkQ+vtdtY28 YcN9WA//R+QrmSPExhfgio5y+aOJDWucqnAcyAusPctLcF7h7j0CdzpwaSRkdaH4 KiLjeyt6tKn8wt8w7m/+SmCsSYXPn81GH/Y5I2F40x6QMrY3cVOXUsulKQA+6ZjZ PmW3bMcz0Dw9IhUK3R/WX96+9UdoytKg5qoTzNzPTKpvKA1yHa/ogl2FnHJS5W+8 Rxz+1oJ70VMIWGpBOc0acHuB2S0RHZ46kPKkPTBgFYEwtmJ8qobvV3r3uQapNaIP 2jnamPu0tAaQoSaJKKSulToziT+sd1sNB+9oyu/kP+t3PXzq4qwp2Gr4jzUYKs4A ZF3DPhMR3YLLN41g/L3rtB0T/YIS287sZRuaLhCqldNpRerSDk4b0HRAksGk1XrI HqYXjWPbRxqYiIUWkInfregSTYJfGPxeLfLKrawNO34/eEV4JrkSKy8d0AJn04EK jTRqI3L7o23ZPxs29uH/3+KK90J3emPZkF7GWVJTEAMsM8jYZduGh7EpsttJLaz/ QnxbTBm9295ahIdCfo/OQhqjWnaNhpbTzf31pyrBZ/itXV7gQ0xjwqPwiyFwI+o/ F/r81xqdwQ3Ni8MKt2c7zLyVA95JHPe95KQ3GrDXR68aByJr4RuhKG8Y2Pj1VOb3 V+Hsu5uhwKrK7Yqe+rHDnJBO00OCO8nwbWhMy2xVxoTkSFCjDmo= =89Zj -----END PGP SIGNATURE----- Merge tag 'devicetree-for-6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull more devicetree updates from Rob Herring: - First part of DT header detangling dropping cpu.h from of_device.h and replacing some includes with forward declarations.
