dm: Rename dev_addr..() functions 2017-06-01T13:03:01+00:00 Simon Glass sjg@chromium.org 2017-05-17T23:18:05+00:00 a821c4af79e4f5ce9b629b20473863397bbe9b10 These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.
